1. Introduction

   MediaTomb is an open source (GPL) UPnP MediaServer with a nice
   web user interface, it allows you to stream your digital media
   through your home network and listen to/watch it on a variety
   of UPnP compatible devices.

   MediaTomb implements the UPnP MediaServer V 1.0 specification
   that can be found on http://www.upnp.org/. The current
   implementation focuses on parts that are required by the
   specification, however we look into extending the functionality
   to cover the optional parts of the spec as well.

   MediaTomb should work with any UPnP compliant MediaRenderer,
   please tell us if you experience difficulties with particular
   models, also take a look at the Supported Devices list for more
   information.

WARNING!

   The server has an integrated file system browser in the UI,
   that means that anyone who has access to the UI can browse your
   file system (with user permissions under which the server is
   running) and also download your data! If you want maximum
   security - disable the UI completely! Account authentication
   offers simple protection that might hold back your kids, but it
   is not secure enough for use in an untrusted environment!

   Note:
          since the server is meant to be used in a home LAN
          environment the UI is enabled by default and accounts
          are deactivated, thus allowing anyone on your network to
          connect to the user interface.

1.1. Currently Supported Features

     * browse and playback your media via UPnP
     * metadata extraction from mp3, ogg, flac, jpeg, etc. files.
     * Exif thumbnail support
     * user defined server layout based on extracted metadata
       (scriptable virtual containers)
     * automatic directory rescans
     * sophisticated web UI with a tree view of the database and
       the file system, allowing to add/remove/edit/browse your
       media
     * highly flexible media format transcoding via plugins /
       scripts
     * allows to watch YouTube(tm) videos on your UPnP player
       device
     * supports last fm scrobbing using lastfmlib
     * on the fly video thumbnail generation with
       libffmpegthumbnailer
     * support for external URLs (create links to internet content
       and serve them via UPnP to your renderer)
     * support for ContentDirectoryService container updates
     * Active Items (experimental feature), allows execution of
       server side scripts upon HTTP GET requests to certain items
     * highly flexible configuration, allowing you to control the
       behavior of various features of the server
     * runs on Linux, FreeBSD, NetBSD, Mac OS X, eCS
     * runs on x86, Alpha, ARM, MIPS, Sparc, PowerPC

2. Requirements

   Note:
          remember to install associated development packages,
          because development headers are needed for compilation!

   Note:
          libupnp is now a part of MediaTomb and does not have to
          be installed separately. We base our heavily patched
          version on libupnp 1.4.1 from http://pupnp.sf.net/

   Note:
          you need at least one database in order to compile and
          run MediaTomb - either sqlite or mysql.

   In order to compile MediaTomb you will have to install the
   following packages.:
     * sqlite (version > 3.x) http://www.sqlite.org/ REQUIRED (if
       mysql is not available)
     * mysql client library (version > 4.0.x) http://mysql.org/
       REQUIRED (if sqlite is not available)
     * expat http://expat.sourceforge.net/ REQUIRED
       Expat is a very good and robust XML parser, since most of
       UPnP is based on XML this package is a requirement.
     * zlib http://www.zlib.net/ OPTIONAL, HIGHLY RECOMMENDED
       Zlib is a compression library that is available on most
       systems, we need it for the database autocreation
       functionality. Make sure to install the zlib development
       package providing zlib.h, if it is not available you will
       need to create the MediaTomb sqlite3/MySQL database
       manually.
     * libmagic OPTIONAL, RECOMMENDED
       This is the 'file' package, it is used to determine the
       mime type of the media. If you don't have this you will
       have to enter file extension to mime type mappings manually
       in your config file.
     * js - SpiderMonkey JavaScript Engine
       http://www.mozilla.org/js/spidermonkey/ OPTIONAL,
       RECOMMENDED, REQUIRED FOR PLAYLIST SUPPORT
       This package is necessary to allow the user defined
       creation of virtual containers. The import.js script
       defines the layout of your media, the default import script
       will create a structure sorted by Audio/Photo/Video, it
       will make use of the gathered metadata (like ID3 tags) to
       sort your music by Artist/Album/Genre/Year , etc. The
       import script can be adjusted and modified - it allows you
       to create the layout that you want.
     * taglib http://developer.kde.org/~wheeler/taglib.html
       OPTIONAL, RECOMMENDED
       This library retrieves metadata from mp3, ogg and flac
       files. You will need it if you want to have virtual objects
       for those files (i.e. nice content layout).

        Note:
                It makes no sense to use taglib and id3lib at the
                same time, the configure script will first look
                for TagLib, if TagLib detection fails it will
                search for id3lib. You can also force the
                configure script to take the library of your
                choice, overriding the default setting.

     * id3lib http://id3lib.sourceforge.net/ (at least version
       3.8.3) OPTIONAL, RECOMMENDED (if TagLib is not available)
       This library retrieves id3 tags from mp3 files.
     * libexif http://libexif.sourceforge.net/ OPTIONAL,
       RECOMMENDED
       You will need this library if you want to extract metadata
       from images, this will allow you to have virtual containers
       for your Photos, sorted by various attributes like Date,
       etc. It also enables thumbnail support: if EXIF thumbnails
       are present in your images they will also be offered via
       UPnP.
     * curl http://curl.haxx.se/ OPTIONAL, REQUIRED FOR YOUTUBE
       AND SOPCAST SUPPORT
       curl is a library that allows to easily fetch content from
       the web, if you want to compile MediaTomb with YouTube
       and/or SopCast support then curl is required.
     * ffmpeg http://ffmpeg.mplayerhq.hu/ OPTIONAL
       Currently ffmpeg is used to gather additional metadata from
       audio and video files.
     * libffmpegthumbnailer
       http://code.google.com/p/ffmpegthumbnailer/ OPTIONAL
       ffmpegthumbnailer is used to generate video thumbnails on
       the fly. If your device (like DSM-510 or PlayStation 3)
       supports video thumbnails it would be worth to compile
       MediaTomb with this library.

        Note:
                ffmpegthumbnailer support is only provided if
                MediaTomb is compiled with ffmpeg support.

     * lastfmlib http://code.google.com/p/lastfmlib/ OPTIONAL
       last.fm scrobbing

   In order to use the web UI you will need to have javascript
   enabled in your web browser.

   The UI has been tested and works with the recent versions of :
     * Firefox/Mozilla
     * Opera

   Tested and does not work with the recent versions of:
     * Konqueror
     * Safari

   Limited functionality with:
     * Internet Explorer 6 and 7

3. Compiling From Source

3.1. Standard Method

   If you don't care about the details - make sure you have
   installed the required packages and the appropriate development
   headers and simply run
$ ./configure
$ make
$ make install

   This should compile and install MediaTomb, the resulting binary
   is ready to run.

   Note:
          if you checked out the sources from SVN the configure
          script will not be available, you will have to create it
          with the following command:

autoreconf -i

3.2. Configure Options

   The MediaTomb configure script provides a large variety of
   options, allowing you to specify the additional libraries that
   will be used, features that will be compiled or disabled,
   workarounds for known bugs in some distributions and so on.
   Some options are straightforward, some require deeper knowledge
   - make sure you know what you are doing :)

3.2.1. Install Location Of Architecture Independent Files

--prefix=PREFIX

   Default:
          /usr/local/

   Install all architecture independent files - all .js files and
   .png images for the Web UI, the import.js script, the service
   description XML files - in the directory of your choice. This
   is especially useful if you do not want to perform a
   system-wide installation, but want to install MediaTomb only
   for your user.

   Important:
          the prefix path will be compiled into the binary; the
          binary will still be relocatable, but you move those
          files you will have to point MediaTomb to the proper
          location by specifying it in the server configuration
          file.

3.2.2. Static Build

--enable-static

   Default:
          disabled

   Build a static binary. This may be useful if you plan to
   install a precompiled MediaTomb binary on a system that does
   not have all the required libraries and where installation of
   those libraries is not possible due to reasons beyond your
   control.

   Note:
          if you enable this option, make sure that you have all
          static versions of the appropriate libraries installed
          on your system. The configure script may not detect that
          those are missing - in this case you will get linker
          errors. Some distributions, for example Fedora Core, do
          not ship static library versions.

3.2.3. Automatically Create Database

--enable-db-autocreate

   Default:
          enabled

   Automatically create the database if it is missing (for example
   upon a first time launch). Disabling this will make the
   resulting binary a little smaller, however you will have to
   take care of the database creation yourself by invoking the
   appropriate .sql scripts that are provided with the package.

   Note:
          the server configuration file has to be setup correctly.
          Either sqlite or MySQL has to be chosen in the storage
          section, for sqlite the database file has to point to a
          writable location, for MySQL the user has to be setup
          with a valid password and permissions and the database
          "mediatomb" has to exist.

3.2.4. Debug Malloc/Realloc Of Zero bytes

--enable-debug-malloc0

   Default:
          disabled

   This feature is only for debugging purposes, whenever a malloc
   or realloc with a value of zero bytes is encountered, the
   server will terminate with abort()

3.2.5. Force Linking With The Pthread Library

--enable-pthread-lib

   Default:
          disabled

   We use the ACX_PTHREAD macro from the autoconf archive to
   determine the way how to link against the pthread library.
   Usually it works fine, but it can fail when cross compiling.
   This configure option tells us to use -lpthread when linking,
   it seems to be needed when building MediaTomb under Optware.
   Note, that using --disable-pthread-lib will not prevent
   automatic checks against the pthread library.

3.2.6. Force Linking With The Iconv Library

--enable-iconv-lib

   Default:
          disabled

   By default we will attempt to use iconv functionality provided
   with glibc, however under some circumstances it may make sense
   to link against a separate iconv library. This option will
   attempt to do that. Note, that using --disable-iconv-lib will
   not prevent automatic attempts to link ageinst the iconv
   library in the case where builtin glibc iconv functionality is
   not available.

3.2.7. Use Atomic Assembler Code For x86 Single CPU systems

--enable-atomic-x86-single

   Default:
          disabled

   Use assembler code suited for single CPU x86 machines. This may
   improve performance, but your binary will not function properly
   on SMP systems. If you specify this for a non x86 architecture
   the binary will not run at all. If you wonder about the purpose
   of assembler code in a mediaserver application: we need it for
   atomic operations that are required for reference counting. The
   pthread library will be used as a fallback for other
   architectures, but can also be forced by a designated configure
   option. This however, will have the worst performance.

   By default x86 SMP code will be used on x86 systems - it will
   reliably work on both SMP and single CPU systems, but will not
   be as fast as the atomic-x86-single option on uniprocessor
   machines.

3.2.8. Use Pthread Code For Atomic Operations

--enable-atomic-pthread

   Default:
          auto detect

   This is the default setting for non x86 architectures, we may
   add assembler optimizations for other architectures as well,
   but currently only x86 optimizations are available. This option
   may also be safely used on x86 machines - the drawback is poor
   performance, compared to assembler optimized code.

3.2.9. Enable SIGHUP Handling

--enable-sighup

   This option turns on SIGHUP handling, every time a SIGHUP is
   caught we will attempt to restart the server and reread the
   configuration file. By default this feature is enabled for x86
   platforms, but is disabled for others. We discovered that
   MediaTomb will not cleanly restart on ARM based systems,
   investigations revealed that this is somehow related to an
   unclean libupnp shutdown. This will be fixed in a later
   release.

   Default:
          auto detect

3.2.10. X_MS_MediaReceiverRegistrar Support

--enable-mrreg-service

   Default:
          disabled

   This option will enable the compilation and support of the
   X_MS_MediaReceiverRegistrar UPnP service, this was implemented
   for future Xbox 360 support. If you have a renderer that
   requires this service, you can safely enable it. It will always
   return true to IsValidated and IsAuthorized requests.

   Note:
          eventhough this service is implemented there is still no
          Xbox 360 support in MediaTomb, more work needs to be
          done.

3.2.11. Playstation 3 Support

--enable-protocolinfo-extension

   Default:
          enabled

   This option allows to send additional information in the
   protocolInfo attribute, this will enable MP3 and MPEG4 playback
   for the Playstation 3, but may also be useful to some other
   renderers.

   Note:
          allthough compiled in, this feature is disabled in
          configuration by default.

3.2.12. Fseeko Check

--disable-fseeko-check

   Default:
          enabled

   This is a workaround for a bug in some Debian distributions,
   disable this check if you know that your system has large file
   support, but configure fails to detect it.

3.2.13. Largefile Support

--disable-largefile

   Default:
          auto

   By default largefile support will be auto detected by
   configure, however you can disable it if you do not want it or
   if you experience problems with it on your system.

3.2.14. Redefinition Of Malloc And Realloc

--disable-rpl-malloc

   Default:
          enabled

   Autoconf may redefine malloc and realloc functions to
   rpl_malloc and rpl_realloc, usually this will happen if the
   autotools think that you are compiling against a non GNU C
   library. Since malloc and realloc may behave different on other
   systems, this gives us the opportunity to write wrapper
   functions to handle special cases. However, this redefinition
   may get triggered when cross compiling, even if you are
   compiling against the GNU C lib. If this is the case, you can
   use this option to disable the redefinition.

3.2.15. SQLite Support

--enable-sqlite3

   Default:
          enabled

   The SQLite database is very easy in installation and use, you
   do not have to setup any users, permissions, etc. A database
   file will be simply created as specified in the MediaTomb
   configuration. At least SQLite version 3 is required.

3.2.16. MySQL Support

--enable-mysql

   Default:
          enabled

   MySQL is a very powerful database, however it requires some
   additional setup. You will find information on how to setup
   MediaTomb with MySQL in the Installation section.

3.2.17. SpiderMonkey LibJS Support

--enable-libjs

   Default:
          enabled

   SpiderMonkey is Mozilla's JavaScript engine, it plays a very
   important role in MediaTomb. We use it to create a nice virtual
   container layout based on the metadata that is extracted from
   your media. We also allow the user to create custom import
   scripts, so everyone has the possibility to adapt the layout to
   ones personal needs. Read more about this in the installation
   section.

   The main problem with this library is, that it is called
   differently on various distributions and that it is installed
   in different locations. For example, it is called js on Fedora,
   but is available under the name of smjs on Debian. If configure
   fails to find your js headers and libraries you can point it to
   the desired locations (see options below).

3.2.18. Filemagic Support

--enable-libmagic

   Default:
          enabled

   This library determines the file type and provides us with the
   appropriate mime type information. It is very important to
   correctly determine the mime type of your media - this
   information will be sent to your renderer. Based on the mime
   type information, the renderer will decide if it can
   play/display the particular file or not. If auto detection
   returns strange mime types, you may want to do a check using
   the 'file' command (the 'file' package must be installed on
   your system). Assuming that you want to check somefile.avi
   enter the following in your terminal:
$ file -i somefile.avi

   This will print the detected mime type, this is exactly the
   information that we use in MediaTomb. You can override auto
   detection by defining appropriate file extension to mime type
   mappings in your configuration file. You can also edit the mime
   type information of an imported object manually via the web UI.

3.2.19. Id3lib Support

--enable-id3lib

   Default:
          disabled, used if taglib is not available

   This library will parse id3 tags of your MP3 files, the
   gathered information will be saved in the database and provided
   via UPnP. Further, the gathered metadata will be used by the
   import script to create a nice container layout
   (Audio/Artist/Album, etc.)

3.2.20. Taglib Support

--enable-taglib

   Default:
          enabled, preffered over id3lib

   This library will parse id3 tags of your MP3 files as well as
   information provided with flac files. It claims to be faster
   than id3lib, but it also seems to have some drawbacks. We had
   some cases where it crashed when trying to parse tags of
   certain MP3 files on embedded systems, we had reports and
   observed that it had problems parsing the sample rates. We also
   did some valgrinding and detected memory leaks. Our feeling is,
   that you will have more stable results with id3lib, however it
   is up to you to enable or disable this library. By default
   id3lib will be taken if both libraries are present on the
   system.

3.2.21. Libexif Support

--enable-libexif

   Default:
          enabled

   The exif library will gather metadata from your photos, it will
   also find exif thumbnails which are created automatically by
   most digital camera models. The gathered data will be used by
   the import script, the thumbnails will be offered as additional
   resources via UPnP.

3.2.22. Inotify Support

--enable-inotify

   Default:
          auto

   Inotify is a kernel mechanism that allows monitoring of
   filesystem events. You need this if you want to use the Inotify
   Autoscan mode, contrary to the Timed mode which recsans given
   directories in specified intervals, Inotify mode will
   immedeately propagate changes in monitored directories on the
   filesystem to the database.

   If you do not specify this option configure will check if
   inotify works on the build system and compile it in only if the
   check succeeds. If you specify this option, the functionality
   will be compiled in even if the build system does not support
   inotify - the availability of inotify will then be checked at
   server runtime.

3.2.23. YouTube Service Support

--enable-youtube

   Default:
          enabled

   This option enabled support of the YouTube service, it allows
   to gather information about content on the YouTube site and
   offers the content via UPnP, thus enabling you to watch your
   favorite YouTube videos on your UPnP player device. The feature
   only makes sense in combination with transcoding, since most
   devices do not support playback of flv files natively.

3.2.24. External Transcoding

--enable-external-transcoding

   Default:
          enabled

3.2.25. Sqlite Backup Defaults

--enable-sqlite-backup-defaults

   Default:
          disabled

   Enables backup option for sqlite as the default setting, might
   be useful for NAS builds.

3.2.26. Curl

--enable-curl

   Default:
          enabled if external transcoding or YouTube features are
          turned on

   It only makes sense to enable the curl library if YouTube and
   External Transcoding are turned on. YouTube requires curl, but
   it's optional for External Transcoding.

3.2.27. Ffmpeg Support

--enable-ffmpeg

   Default:
          enabled

   Currently the ffmpeg library is used to extract additional
   information from audio and video files. It is also capable of
   reading out the tag information from theora content. It is not
   yet used for transcoding, so this feature only gathers
   additional metadata.

3.2.28. Ffmpeg Thumbnailer Support

--enable-ffmpegthumbnailer

   Default:
          enabled

   Compiling with ffmpegthumbnailer support is only possible if
   you also compile with ffmpeg support. The library allows to
   generate thumbnails for the videos on the fly.

3.2.29. MediaTomb Debug Output

--enable-tombdebug

   Default:
          disabled

   This option enables debug output, the server will print out a
   lot of information which is mainly interesting to developers.
   Use this if you are trying to trace down a bug or a problem,
   the additional output may give you some clues.

3.2.30. UPnP Library Debug Output

--enable-upnpdebug

   Default:
          disabled

   This option enables debug output of the UPnP SDK. You should
   not need it under normal circumstances.

3.2.31. Log Output

--disable-log

   Default:
          enabled

   This option allows you to suppress all log output from the
   server.

3.2.32. Debug Log Output

   Default:
          enabled

   This option allows you to compile the server with debug
   messages. If enabled, switching between verbose and normal
   output during runtime becomes possible.

3.2.33. Package Search Directory

--with-search=DIR

   Default:
          /opt/local/ on Darwin, /usr/local/ on all other systems

   Some systems may have whole sets of packages installed in an
   alternative location, for example Darwinports on OSX get
   installed to /opt/local/. This option tells the configure
   script to additionally search for headers and libraries of
   various packages in DIR/include and DIR/lib.

3.2.34. Specifying Header And Library Locations Of Various Packages

   You can specify the exact location of particular headers and
   libraries. Some packages use extra programs that tell us the
   appropriate flags that are needed for compilation - like
   mysql_config. You can also specify the exact location of those
   programs. The parameters are self explanatory, in case of
   headers and libraries the DIR parameter is the directory where
   those headers and libraries are located.
--with-sqlite3-h=DIR               search for sqlite3 headers only in DI

3.2.35. The devconf Script

   If you are doing some development work and some debugging, you
   will probably want to compile with the -g flag and also disable
   optimization. The devconf script does exactly that. In
   addition, it accepts command line parameters that are passed to
   the configure script.

4. Initial Installation

4.1. Network Setup

   Some systems require a special setup on the network interface.
   If MediaTomb exits with UPnP Error -117, or if it does not
   respond to M-SEARCH requests from the renderer (i.e. MediaTomb
   is running, but your renderer device does not show it) you
   should try the following settings (the lines below assume that
   MediaTomb is running on a Linux machine, on network interface
   eth1):
# route add -net 239.0.0.0 netmask 255.0.0.0 eth1
# ifconfig eth1 allmulti

   Those settings will be applied automatically by the init.d
   startup script.

   You should also make sure that your firewall is not blocking
   port UDP port 1900 (required for SSDP) and UDP/TCP port of
   MediaTomb. By default MediaTomb will select a free port
   starting with 49152, however you can specify a port of your
   choice in the configuration file.

4.2. First Time Launch

   When starting MediaTomb for the first time, a .mediatomb
   directory will be created in your home. Further, a default
   server configuration file, called config.xml will be generated
   in that directory.

4.2.1. Using Sqlite Database

   If you are using sqlite - you are ready to go, the database
   file will be created automatically and will be located
   ~/.mediatomb/mediatomb.db If needed you can adjust the database
   file name and location in the server configuration file.

4.2.2. Using MySQL Database

   If MediaTomb was compiled with support for both databases,
   sqlite will be chosen as default because the initial database
   can be created and used without any user interaction. If
   MediaTomb was compiled only with MySQL support, the appropriate
   config.xml file will be created in the ~/.mediatomb directory,
   but the server will then terminate, because user interaction is
   required.

   MediaTomb has to be able to connect to the MySQL server and at
   least the (empty) database has to exist. To create the database
   and provide MediaTomb with the ability to connect to the MySQL
   server you need to have the appropriate permissions. Note that
   user names and passwords in MySQL have nothing to do with UNIX
   accounts, MySQL has it's own user names/passwords. Connect to
   the MySQL database as "root" or any other user with the
   appropriate permissions:
$ mysql [-u <username>] [-p]

   (You'll probably need to use "-u" to specify a different MySQL
   user and "-p" to specify a password.)

   Create a new database for MediaTomb: (substitute "<database
   name>" with the name of the database)
mysql> CREATE DATABASE <database name>;

   (You can also use "mysqladmin" instead.)

   Give MediaTomb the permissions to access the database:
mysql> GRANT ALL ON <database name>.*
       TO '<user name>'@'<hostname>'
       IDENTIFIED BY '<password>';

   If you don't want to set a password, omit "IDENTIFIED BY .."
   completely. You could also use the MySQL "root" user with
   MediaTomb directly, but this is not recommended.

   To create a database and a user named "mediatomb" (who is only
   able to connect via "localhost") without a password (the
   defaults) use:
mysql> CREATE DATABASE mediatomb;
mysql> GRANT ALL ON mediatomb.* TO 'mediatomb'@'localhost';

   If MediaTomb was compiled with database auto creation the
   tables will be created automatically during the first startup.
   All table names have a "mt_" prefix, so you can theoretically
   share the database with a different application. However, this
   is not recommended.

   If database auto creation wasn't compiled in (configure was run
   with the "--disable-db-autocreate" or zlib.h was not available)
   you have to create the tables manually:
$ mysql [-u <username>] [-p] \
  <database name> < \
  <install prefix>/share/mediatomb/mysql.sql

   After creating the database and making the appropriate changes
   in your MediaTomb config file you are ready to go - launch the
   server, and everything should work.

5. Command Line Options

   There is a number of options that can be passed via command
   line upon server start up, for a short summary you can invoke
   MediaTomb with the following parameter:
$ mediatomb --help

   Note:
          the command line options override settings in the
          configuration file!

5.1. IP Address

--ip or -i

   The server will bind to the given IP address, currently we can
   not bind to multiple interfaces so binding to 0.0.0.0 will not
   be possible.

5.2. Interface

--interface or -e

   Interface to bind to, for example eth0, this can be specified
   instead of the ip address.

5.3. Port

--port or -p

   Specify the server port that will be used for the web user
   interface, for serving media and for UPnP requests, minimum
   allowed value is 49152. If this option is omitted a default
   port will be chosen, however, in this case it is possible that
   the port will change upon server restart.

5.4. Configuration File

 --config or -c

   By default MediaTomb will search for a file named "config.xml"
   in the ~/.mediatomb directory. This option allows you to
   specify a config file by the name and location of your choice.
   The file name must be absolute.

5.5. Daemon Mode

--daemon or -d

   Run the server in background, MediaTomb will shutdown on
   SIGTERM, SIGINT and restart on SIGHUP.

5.6. Home Directory

--home or -m

   Specify an alternative home directory. By default MediaTomb
   will try to retrieve the users home directory from the
   environment, then it will look for a .mediatomb directory in
   users home. If .mediatomb was found we will try to find the
   default configuration file (config.xml), if not found we will
   create both, the .mediatomb directory and the default config
   file.

   This option is useful in two cases: when the home directory can
   not be retrieved from the environment (in this case you could
   also use -c to point MediaTomb to your configuration file or
   when you want to create a new configuration in a non standard
   location (for example, when setting up daemon mode). In the
   latter case you can combine this parameter with the parameter
   described in Section 5.7, "Config Directory"

5.7. Config Directory

--cfgdir or -f

   The default configuration directory is combined out of the
   users home and the default that equals to .mediatomb, this
   option allows you to override the default directory naming.
   This is useful when you want to setup the server in a
   nonstandard location, but want that the default configuration
   to be written by the server.

5.8. Write PID File

--pidfile or -P

   Specify a file that will hold the server process ID, the
   filename must be absolute.

5.9. Run Under Different User Name

--user or -u

   Run MediaTomb under the specified user name, this is especially
   useful in combination with the daemon mode.

5.10. Run Under Different Group

--group or -g

   Run MediaTomb under the specified group, this is especially
   useful in combination with the daemon mode.

5.11. Add Content

--add or -a

   Add the specified directory or file name to the database
   without UI interaction. The path must be absolute, if path is a
   directory then it will be added recursively. If path is a file,
   then only the given file will be imported.

5.12. Log To File

--logfile or -l

   Do not output log messages to stdout, but redirect everything
   to a specified file.

5.13. Debug Output

--debug or -D

   Enable debug log output.

5.14. Compile Info

--compile-info

   Print the configuration summary (used libraries and enabled
   features) and exit.

5.15. Version Information

--version

   Print version information and exit.

5.16. Display Command Line Summary

--help or -h

   Print a summary about the available command line options.

6. Configuration File

   MediaTomb is highly configurable and allows the user to set
   various options and preferences that define the servers
   behavior. Rather than enforcing certain features upon the user,
   we prefer to offer a number of choices where possible. The
   heart of MediaTomb configuration is the config.xml file, which
   is located in the ~/.mediatomb directory. If the configuration
   file is not found in the default location and no configuration
   was specified on the command line, MediaTomb will generate a
   default config.xml file in the ~/.mediatomb directory. The file
   is in the XML format and can be edited by a simple text editor,
   here is the list of all available options:
     * "Required" means that the server will not start if the tag
       is missing in the configuration.
     * "Optional" means that the tag can be left out of the
       configuration file.

   The root tag of MediaTomb configuration is:
<config>

6.1. Server Settings

   These settings define the server configuration, this includes
   UPnP behavior, selection of database, accounts for the UI as
   well as installation locations of shared data.
<server>

   Required

   This section defines the server configuration parameters.

   Child tags:
     *
<port>0</port>

       Optional
       Default: 0 (automatic)
       Specifies the port where the server will be listening for
       HTTP requests. Note, that because of the implementation in
       the UPnP SDK only ports above 49152 are supported. The
       value of zero means, that a port will be automatically
       selected by the SDK.
     *
<ip>192.168.0.23</ip>

       Optional
       Default: ip of the first available interface.
       Specifies the IP address to bind to, by default one of the
       available interfaces will be selected.
     *
<interface>eth0</interface>

       Optional
       Default: first available interface.
       Specifies the interface to bind to, by default one of the
       available interfaces will be selected.
     *
<name>MediaTomb</name>

       Optional
       Default: MediaTomb
       Server friendly name, you will see this on your devices
       that you use to access the server.
     *
<manufacturerURL>http://mediatomb.org/</manufacturerURL>

       Optional
       Default: http://mediatomb.cc/
       This tag sets the manufacturer URL of a UPnP device, a
       custom setting may be necessary to trick some renderers in
       order to enable special features that otherwise are only
       active with the vendor implemented server.
     *
<modelName>MediaTomb</modelName>

       Optional
       Default: MediaTomb
       This tag sets the model name of a UPnP device, a custom
       setting may be necessary to trick some renderers in order
       to enable special features that otherwise are only active
       with the vendor implemented server.
     *
<modelNumber>0.9.0</modelNumber>

       Optional
       Default: MediaTomb version
       This tag sets the model number of a UPnP device, a custom
       setting may be necessary to trick some renderers in order
       to enable special features that otherwise are only active
       with the vendor implemented server.
     *
<serialNumber>1</serialNumber>

       Optional
       Default: 1
       This tag sets the serial number of a UPnP device.
     *
<presentationURL append-to="ip">80/index.html</presentationURL>

       Optional
       Default: "/"
       The presentation URL defines the location of the servers
       user interface, usually you do not need to change this
       however, vendors who want to ship our server along with
       their NAS devices may want to point to the main
       configuration page of the device.
       Attributes:
          +
append-to=...

            Optional
            Default: "none"
            The append-to attribute defines how the text in the
            presentationURL tag should be treated.
            The allowed values are:
append-to="none"

            Use the string exactly as it appears in the
            presentationURL tag.
append-to="ip"

            Append the string specified in the presentationURL tag
            to the ip address of the server, this is useful in a
            dynamic ip environment where you do not know the ip
            but want to point the URL to the port of your web
            server.
append-to="port"

            Append the string specified in the presentationURL tag
            to the server ip and port, this may be useful if you
            want to serve some static pages using the built in web
            server.
     *
<udn/>

       Required
       Default: automatically generated if the tag is empty
       Unique Device Name, according to the UPnP spec it must be
       consistent throughout reboots. You can fill in something
       yourself, but we suggest that you leave this tag empty - it
       will be filled out and saved automatically after the first
       launch of the server.
     *
<home>/home/your_user_name/.mediatomb</home>

       Required
       Default: ~/.mediatomb
       Server home - the server will search for the data that it
       needs relative to this directory - basically for the sqlite
       database file. The mediatomb.html bookmark file will also
       be generated in that directory.
     *
<webroot>/usr/share/mediatomb/web</webroot>

       Required
       Default: depends on the installation prefix that is passed
       to the configure script.
       Root directory for the web server, this is the location
       where device description documents, UI html and js files,
       icons, etc. are stored.
     *
<servedir>/home/myuser/mystuff</servedir>

       Optional
       Default: empty (disabled)
       Files from this directory will be served as from a regular
       web server. They do not need to be added to the database,
       but they are also not served via UPnP browse requests.
       Directory listing is not supported, you have to specify
       full paths.

        Example:
                the file something.jar is located in
                /home/myuser/mystuff/javasubdir/something.jar on
                your filesystem. Your ip address is 192.168.0.23,
                the server is running on port 50500. Assuming the
                above configuration you could download it by
                entering this link in your web browser:
                http://192.168.0.23:50500/content/serve/javasubdir
                /something.jar

     *
<alive>180</alive>

       Optional
       Default: 180, this is according to the UPnP specification.
       Interval for broadcasting SSDP:alive messages
     *
<protocolInfo extend="no"/>

       Optional
       Default: no
       Adds specific tags to the protocolInfo attribute, this is
       required to enable MP3 and MPEG4 playback on Playstation 3.
     *
<pc-directory upnp-hide="no"/>

       Optional
       Default: no
       Enabling this option will make the PC-Directory container
       invisible for UPnP devices.

        Note:
                independent of the above setting the container
                will be always visible in the web UI!

     *
<tmpdir>/tmp/</tmpdir>

       Optional
       Default: /tmp/
       Selects the temporary directory that will be used by the
       server.
     *
<bookmark>mediatomb.html</bookmark>

       Optional
       Default: mediatomb.html
       The bookmark file offers an easy way to access the user
       interface, it is especially helpful when the server is not
       configured to run on a fixed port. Each time the server is
       started, the bookmark file will be filled in with a
       redirect to the servers current IP address and port. To use
       it, simply bookmark this file in your browser, the default
       location is ~/.mediatomb/mediatomb.html
     *
<custom-http-headers>

       Optional
       This section holds the user defined HTTP headers that will
       be added to all HTTP responses that come from the server.
       Child tags:
          +
<add header="..."/>
<add header="..."/>
...

            Optional
            Specify a header to be added to the response. If you
            have a DSM-320 use <add header="X-User-Agent:
            redsonic"/> to fix the .AVI playback problem.
     *
<upnp-string-limit>

       Optional
       Default: disabled
       This will limit title and description length of containers
       and items in UPnP browse replies, this feature was added a
       s workaround for the TG100 bug which can only handle titles
       no longer than 100 characters. A negative value will
       disable this feature, the minimum allowed value is "4"
       because three dots will be appended to the string if it has
       been cut off to indicate that limiting took place.

     *
<ui enabled="yes" poll-interval="2" poll-when-idle="no"/>

       Optional
       This section defines various user interface settings.
       WARNING!
       The server has an integrated filesystem browser, that means
       that anyone who has access to the UI can browse your
       filesystem (with user permissions under which the server is
       running) and also download your data! If you want maximum
       security - disable the UI completely! Account
       authentication offers simple protection that might hold
       back your kids, but it is not secure enough for use in an
       untrusted environment!

        Note:
                since the server is meant to be used in a home LAN
                environment the UI is enabled by default and
                accounts are deactivated, thus allowing anyone on
                your network to connect to the user interface.

       Attributes:
          +
enabled=...

            Optional
            Default: yes
            Enables ("yes") or disables ("no") the web user
            interface.
          +
show-tooltips=...

            Optional
            Default: yes
            This setting specifies if icon tooltips should be
            shown in the web UI.
          +
poll-interval=...

            Optional
            Default: 2
            The poll-interval is an integer value which specifies
            how often the UI will poll for tasks. The interval is
            specified in seconds, only values greater than zero
            are allowed.
          +
poll-when-idle=...

            Optional
            Default: no
            The poll-when-idle attribute influences the behavior
            of displaying current tasks: - when the user does
            something in the UI (i.e. clicks around) we always
            poll for the current task and will display it - if a
            task is active, we will continue polling in the
            background and update the current task view
            accordingly - when there is no active task (i.e. the
            server is currently idle) we will stop the background
            polling and only request updates upon user actions,
            but not when the user is idle (i.e. does not click
            around in the UI)
            Setting poll-when-idle to "yes" will do background
            polling even when there are no current tasks; this may
            be useful if you defined multiple users and want to
            see the tasks the other user is queuing on the server
            while you are actually idle.
            The tasks that are monitored are:
               o adding files or directories
               o removing items or containers
               o automatic rescans
       Child tags:
          +
<accounts enabled="yes" session-timeout="30"/>

            Optional
            This section holds various account settings.
            Attributes:
               o
enabled=...

                 Optional
                 Default: yes
                 Specifies if accounts are enabled ("yes") or
                 disabled ("no").
               o
session-timeout=...

                 Optional
                 Default: 30
                 The session-timeout attribute specifies the
                 timeout interval in minutes. The server checks
                 every five minutes for sessions that have timed
                 out, therefore in the worst case the session
                 times out after session-timeout + 5 minutes.
            Accounts can be defined as shown below:
               o
<account user="name" password="password"/>
<account user="name" password="password"/>
....

                 Optional
                 There can be multiple users, however this is
                 mainly a feature for the future. Right now there
                 are no per-user permissions.
          +
<items-per-page default="25">

            Optional
            Default: 25
            This sets the default number of items per page that
            will be shown when browsing the database in the web
            UI.
            The values for the items per page drop down menu can
            be defined in the following manner:
               o
<option>10</option>
<option>25</option>
<option>50</option>
<option>100</option>

                 Default: 10, 25, 50, 100

                    Note:
                            this list must contain the default
                            value, i.e. if you define a default
                            value of 25, then one of the <option>
                            tags must also list this value.

     *
<storage caching="yes">

       Required
       Defines the storage section - database selection is done
       here. Currently sqlite3 and mysql are supported. Each
       storage driver has it's own configuration parameters.
          +
caching="yes"

            Optional
            Default: yes
            Enables caching, this feature should improve the
            overall import speed.
          +
<sqlite enabled="yes>

            Required if MySQL is not defined
            Allowed values are "sqlite3" or "mysql", the available
            options depend on the selected driver.
               o
enabled="yes"

                 Optional
                 Default: yes
            Below are the sqlite driver options:
               o
<database-file>mediatomb.db</database-file>

                 Optional
                 Default: mediatomb.db
                 The database location is relative to the server's
                 home, if the sqlite database does not exist it
                 will be created automatically.
               o
<synchronous>off</synchronous>

                 Optional
                 Default: off
                 Possible values are "off", "normal" and "full".
                 This option sets the SQLite pragma "synchronous".
                 This setting will affect the performance of the
                 database write operations. For more information
                 about this option see the SQLite documentation:
                 http://www.sqlite.org/pragma.html#pragma_synchron
                 ous
               o
<on-error>restore</on-error>

                 Optional
                 Default: restore
                 Possible values are "restore" and "fail".
                 This option tells MediaTomb what to do if an
                 SQLite error occurs (no database or a corrupt
                 database). If it is set to "restore" it will try
                 to restore the database from a backup file (if
                 one exists) or try to recreate a new database
                 from scratch.
                 If the option is set to "fail", MediaTomb will
                 abort on an SQLite error.
               o
<backup enabled="no" interval="6000"/>

                 Optional
                 Backup parameters:
                    #
enabled=...

                      Optional
                      Default: no
                      Enables or disables database backup.
                    #
interval=...

                      Optional
                      Default: 600
                      Defines the backup interval in seconds.
          +
<mysql enabled="no"/>

            Defines the MySQL storage driver section.
               o
enabled=...

                 Optional
                 Default: yes
                 Enables or disables the MySQL driver.
            Below are the child tags for MySQL:
               o
<host>localhost</host>

                 Optional
                 Default: "localhost"
                 This specifies the host where your MySQL database
                 is running.
               o
<port>0</port>

                 Optional
                 Default: 0
                 This specifies the port where your MySQL database
                 is running.
               o
<username>root</username>

                 Optional
                 Default: "mediatomb"
                 This option sets the user name that will be used
                 to connect to the database.
               o
<password></password>

                 Optional
                 Default: no password
                 Defines the password for the MySQL user. If the
                 tag doesn't exist MediaTomb will use no password,
                 if the tag exists, but is empty MediaTomb will
                 use an empty password. MySQL has a distinction
                 between no password and an empty password.
               o
<database>mediatomb</database>

                 Optional
                 Default: "mediatomb"
                 Name of the database that will be used by
                 MediaTomb.

6.1.1. Extended Runtime Options

<extended-runtime-options>

   These options reside under the server tag and allow to
   additinally control the so called "runtime options". The
   difference to the import options is:

   Import options are only triggered when data is being imported
   into the database, this means that if you want new settings to
   be applied to already imported data, you will have to reimport
   it. Runtime options can be switched on and off without the need
   to reimport any media. Unfortunately you still need to restart
   the server so that these options take effect, however after
   that they are immediately active.
     *
<ffmpegthumbnailer enabled="no">

       Optional
       Default: no
       Ffmpegthumbnailer is a nice, easy to use library that
       allows to generate thumbnails from video files. Some DLNA
       compliant devices support video thumbnails, if you think
       that your device may be one of those you can try enabling
       this option. It would also make sense to enable the
       protocolInfo option, since it will add specific DLNA tags
       to tell your device that a video thumbnail is being offered
       by the server.

        Note:
                thumbnails are not cached and not stored anywhere,
                they will be generated on the fly in memory and
                released afterwards. If your device supports video
                thumbnails and requests them from the server in
                large amounts, the performance when browsing video
                containers will depend on the speed of your
                machine. A feature to allow caching of thumbnails
                is planned for future releases.

       The following options allow to control the
       ffmpegthumbnailer library (these are basically the same
       options as the ones offered by the ffmpegthumbnailer
       command line application). All tags below are optional and
       have sane default values.
          +
<thumbnail-size>128</thumbnail-size>

            Optional
            Default: 128
            The thumbnail size should not exceed 160x160 pixels,
            higher values can be used but will mostprobably not be
            supported by DLNA devices. The value of zero or less
            is not allowed.
          +
<seek-percentage>5</seek-percentage>

            Optional
            Default: 5
            Time to seek to in the movie (percentage), values less
            than zero are not allowed.
          +
<filmstrip-overlay>yes</filmstrip-overlay>

            Optional
            Default: yes
            Creates a filmstrip like border around the image, turn
            this option off if you want pure images.
          +
<image-quality>8</image-quality>

            Optional
            Default: 8
            Sets the image quality of the generated thumbnails.
          +
<workaround-bugs>no</workaround-bugs>

            Optional
            Default: no
            Accodring to ffmpegthumbnailer documentation, this
            option will enable workarounds for bugs in older
            ffmpeg versions. You can try enabling it if you
            experience unexpected behaviour, like hangups during
            thumbnail generation, crashes and alike.
     *
<lastfm enabled="no">

       Optional
       Support for the last.fm service.
          +
<username>login</username>

            Required
            Your last.fm user name.
          +
<password>pass</password>

            Required
            Your last.fm password.
     *
<mark-played-items enabled="no" suppress-cds-updates="yes">

       Optional
       The attributes of the tag have the following meaning:
          +
enabled=...

            Optional
            Default: no
            Enables or disables the marking of played items, seto
            to "yes" to enable the feature.
          +
suppress-cds-updates=...

            Optional
            Default: yes
            This is an advanced feature, leave the default setting
            if unsure. Usually, when items are modified we send
            out container updates as specified in the Content
            Directory Service. This notifies the player that data
            in a particular container has changed, players that
            support CDS updates will rebrowse the container and
            refresh the view. However, in this case we probably do
            not want it (this actually depends on the particular
            player implementation). For example, if we update the
            list of currently playing items, the player could
            interrupt playback and rebrowse the current container
            - clearly an unwatned behaviour. Because of this, we
            provide an option to suppress and not send out
            container updates - only for the case where the item
            is marked as "played". In order to see the changes you
            will have to get out of the current container and
            enter it again - then the view on your player should
            get updated.

              Note:
                      some players (i.e. PS3) cache a lot of data
                      and do not react to container updates, for
                      those players it may be necessary to leave
                      the server view or restart the player in
                      order to update content (same as when adding
                      new data).

       The following tag defines how played items should be
       marked:
          +
<string mode="prepend">* </string>

            Optional
            Default: *
            Specifies what string should be appended or prepended
            to the title of the object that will be marked as
            "played".
               o
mode=...

                 Optional
                 Default: prepend
                 Specifies how a string should be added to the
                 object's title, allowed values are "append" and
                 "prepend".
          +
<mark>

            Optional
            This subsection allows to list which type of content
            should get marked. We figured, that marking played
            items is mostly useful for videos, mainly for watching
            series. It could also be used with audio and image
            content, but otherwise it's probably useless. Thefore
            we decided to specify only three supported types that
            can get marked:
               o
<content>audio</content>
<content>video</content>
<content>image</content>

                 You can specify any combination of the above tags
                 to mark the items you want.

6.2. Import Settings

   The import settings define various options on how to aggregate
   the content.
<import hidden-files="no">

   Optional

   This tag defines the import section.

   Attributes:
     *
hidden-files=...

       Optional
       Default: no
       This attribute defines if files starting with a dot will be
       imported into the database ("yes"). Autoscan can override
       this attribute on a per directory basis.

   Child tags:
     *
<filesystem-charset>ISO-8859-1</filesystem-charset>

       Optional
       Default: if nl_langinfo() function is present, this setting
       will be auto detected based on your system locale, else set
       to ISO-8859-1
       Defines the charset of the filesystem. For example, if you
       have file names in Cyrillic KOI8-R encoding, then you
       should specify that here. The server uses UTF-8 internally,
       this import parameter will help you to correctly import
       your data.
     *
<metadata-charset>ISO-8859-1</metadata-charset>

       Optional
       Default: if nl_langinfo() function is present, this setting
       will be auto detected based on your system locale, else set
       to ISO-8859-1
       Same as above, but defines the charset of the metadata
       (i.e. id3 tags, Exif information, etc.)
     *
<scripting script-charset="UTF-8">

       Optional
       Defines the scripting section.
          +
script-charset=...

            Optional
            Default: UTF-8
       Below are the available scripting options:
          +
<virtual-layout type="builtin">

            Optional
            Defines options for the virtual container layout; the
            so called "virtual container layout" is the way how
            the server organizes the media according to the
            extracted metadata. For example, it allows sorting
            audio files by Album, Artist, Year and so on.
               o
type=...

                 Optional
                 Default: builtin
                 Specifies what will be used to create the virtual
                 layout, possible values are:
                    # builtin: a default layout will be created by
                      the server
                    # js: a user customizable javascript will be
                      used (MediaTomb must be compiled with js
                      support)
                    # disabled: only PC-Directory structure will
                      be created, i.e. no virtual layout
            The virtual layout can be adjusted using an import
            script which is defined as follows:
               o
<import-script>/path/to/my/import-script.js</import-script>

                 Required if virtual layout type is "js"
                 Default: ${prefix}/share/mediatomb/js/import.js,
                 where ${prefix} is your installation prefix
                 directory.
                 Points to the script invoked upon media import.

               o
<dvd-script>/path/to/my/import-dvd.js</dvd-script>

                 Optional, only has effect when layout type is
                 "js" and if MediaTomb was compiled with
                 libdvdread support.
                 Default:
                 ${prefix}/share/mediatomb/js/import-dvd.js, where
                 ${prefix} is your installation prefix directory.
                 Points to the script invoked upon import of DVD
                 iso images. For more details read
                 doc/scripting.txt
          +
<common-script>/path/to/my/common-script.js</common-script>

            Optional
            Default: ${prefix}/share/mediatomb/js/common.js, where
            ${prefix} is your installation prefix directory.
            Points to the so called common script - think of it as
            a custom library of js helper functions, functions
            added there can be used in your import and in your
            playlist scripts. For more details read
            doc/scripting.txt

<playlist-script create-link="yes">/path/to/my/playlist-script.js</playl
ist-script>

            Optional
            Default: ${prefix}/share/mediatomb/js/playlists.js,
            where ${prefix} is your installation prefix directory.
            Points to the script that is parsing various
            playlists, by default parsing of pls and m3u playlists
            is implemented, however the script can be adapted to
            parse almost any kind of text based playlist. For more
            details read doc/scripting.txt
               o
create-link=...

                 Optional
                 Default: yes
                 Links the playlist to the virtual container which
                 contains the expanded playlist items. This means,
                 that if the actual playlist file is removed from
                 the database, the virtual container corresponding
                 to the playlist will also be removed.
     *
<magic-file>/path/to/my/magic-file</magic-file>

       Optional
       Default: System default
       Specifies an alternative file for filemagic, containing
       mime type information.
     *
<autoscan use-inotify="auto">

       Optional
       Specifies a list of default autoscan directories.
       This section defines persistent autoscan directories. It is
       also possible to define autoscan directories in the UI, the
       difference is that autoscan directories that are defined
       via the config file can not be removed in the UI. Even if
       the directory gets removed on disk, the server will try to
       monitor the specified location and will re add the removed
       directory if it becomes available/gets created again.
          +
use-inotify=...

            Optional
            Default: auto
            Specifies if the inotify autoscan feature should be
            enabled. The default value is "auto", which means that
            availability of inotify support on the system will be
            detected automatically, it will then be used if
            available. Setting the option to 'no' will disable
            inotify even if it is available. Allowed values:
            "yes", "no", "auto"
       Child tags:
          +
<directory location="/media" mode="timed" interval="3600"
    level="full" recursive="no" hidden-files="no"/>
<directory location="/audio" mode="inotify"
    recursive="yes" hidden-files="no"/>
...

            Optional
            Defines an autoscan directory and it's parameters.
            The attributes specify various autoscan options:
               o
location=...

                 Required
                 Absolute path to the directory that shall be
                 monitored.
               o
mode=...

                 Required
                 Scan mode, currently "inotify" and "timed" are
                 supported. Timed mode rescans the given directory
                 in specified intervals, inotify mode uses the
                 kernel inotify mechanism to watch for filesystem
                 events.
               o
interval=...

                 Required for "timed" mode
                 Scan interval in seconds.
               o
level=...

                 Required for "timed" mode
                 Either "full" or "basic". Basic mode will only
                 check if any files have been added or were
                 deleted from the monitored directory, full mode
                 will remember the last modification time and re
                 add the media that has changed. Full mode might
                 be useful when you want to monitor changes in the
                 media, like id3 tags and alike.
               o
recursive=...

                 Required
                 Values of "yes" or "no" are allowed, specifies if
                 autoscan shall monitor the given directory
                 including all sub directories.
               o
hidden-files=...

                 Optional
                 Default: value specified in <import
                 hidden-files=""/>
                 Allowed values: "yes" or "no", process hidden
                 files, overrides the hidden-files value in the
                 <import/> tag.
     *
<mappings>

       Optional
       Defines various mapping options for importing media,
       currently two subsections are supported.
       This section defines mime type and upnp:class mappings, it
       is vital if filemagic is not available - in this case media
       type auto detection will fail and you will have to set the
       mime types manually by matching the file extension. It is
       also helpful if you want to override auto detected mime
       types or simply skip filemagic processing for known file
       types.
          +
<extension-mimetype ignore-unknown="no" case-sensitive="no">

            Optional
            This section holds the file name extension to mime
            type mappings.
            Attributes:
               o
ignore-unknown=...

                 Optional
                 Default: no
                 If ignore-unknown is set to "yes", then only the
                 extensions that are listed in this section are
                 imported.
               o
case-sensitive=...

                 Optional
                 Default: no
                 Specifies if extensions listed in this section
                 are case sensitive, allowed values are "yes" or
                 "no".
            Child tags:
               o
<map from="mp3" to="audio/mpeg"/>

                 Optional
                 Specifies a mapping from a certain file name
                 extension (everything after the last dot ".") to
                 mime type.

                    Note:
                            this improves the import speed,
                            because invoking libmagic to discover
                            the right mime type of a file is
                            omitted for files with extensions
                            listed here.

                    Note:
                            extension is case sensitive, this will
                            probably need to be fixed.

          +
<mimetype-upnpclass>

            Optional
            This section holds the mime type to upnp:class
            mappings.
            Child tags:
               o
<map from="audio/*" to="object.item.audioItem.musicTrack"/>

                 Optional
                 Specifies a mapping from a certain mime type to
                 upnp:class in the Content Directory. The mime
                 type can either be entered explicitly
                 "audio/mpeg" or using a wildcard after the slash
                 "audio/*". The values of "from" and "to"
                 attributes are case sensitive.
          +
<mimetype-contenttype>

            Optional
            This section makes sure that the server knows about
            remapped mimetypes and still extracts the metadata
            correctly. For example, we know that id3lib can only
            handle mp3 files, the default mimetype of mp3 content
            is audio/mpeg. If the user remaps mp3 files to a
            different mimetype, we must know about it so we can
            still pass this item to id3lib for metadata
            extraction.

              Note:
                      if this section is not present in your
                      config file, the defaults will be filled in
                      automatically. However, if you add an empty
                      tag, without defining the following <treat>
                      tags, the server will assume that you want
                      to have an empty list and no files will be
                      process by the metadata handler.

               o
<treat mimetype="audio/mpeg" as="mp3"/>

                 Optional
                 Tells the server what content the specified
                 mimetype actually is.

                    Note:
                            it makes no sense to define 'as'
                            values that are not below, the server
                            only needs to know the content type of
                            the ones specified, otherwise it does
                            not matter.

                 The 'as' attribute can have following values:
                    #
mp3

                      Default mimetype: audio/mpeg
                      The content is an mp3 file and should be
                      processed by either id3lib or taglib (if
                      available).
                    #
ogg

                      Default mimetype: application/ogg
                      The content is an ogg file and should be
                      processed by taglib (if available).
                    #
flac

                      Default mimetype: audio/x-flac
                      The content is a flac file and should be
                      processed by taglib (if available).
                    #
jpg

                      Default mimetype: image/jpeg
                      The content is a jpeg image and should be
                      processed by libexif (if available).
                    #
playlist

                      Default mimetype: audio/x-mpegurl or
                      audio/x-scpls
                      The content is a playlist and should be
                      processed by the playlist parser script.
                    #
pcm

                      Default mimetype: audio/L16 or audio/x-wav
                      The content is a PCM file.
                    #
avi

                      Default mimetype: video/x-msvideo
                      The content is an AVI container, FourCC
                      extraction will be attempted.
     *
<library-options>

       Optional
       This section holds options for the various supported import
       libraries, it is useful in conjunction with virtual
       container scripting, but also allows to tune some other
       features as well.
       Currently the library-options allow additional extraction
       of the so called auxilary data (explained below) and
       provide control over the video thumbnail generation.
       Here is some information on the auxdata: UPnP defines
       certain tags to pass along metadata of the media (like
       title, artist, year, etc.), however some media provides
       more metadata and exceeds the scope of UPnP. This
       additional metadata can be used to fine tune the server
       layout, it allows the user to create a more complex
       container structure using a customized import script. The
       metadata that can be extracted depends on the library,
       currently we support libebexif which provides a default set
       of keys that can be passed in the options below. The data
       according to those keys will the be extracted from the
       media and imported into the database along with the item.
       When processing the item, the import script will have full
       access to the gathered metadata, thus allowing the user to
       organize the data with the use of the extracted
       information. A practical example would be: if have more
       than one digital camera in your family you could extract
       the camera model from the Exif tags and sort your photos in
       a structure of your choice, like:
       Photos/MyCamera1/All Photos
       Photos/MyCamera1/Date
       Photos/MyCamera2/All Photos
       Photos/MyCamera2/Date
       etc.
       Child tags:
          +
<libexif>

            Optional
            Options for the exif library.
            Child tags:
               o
<auxdata>

                 Optional
                 Currently only adding keywords to auxdata is
                 supported. For a list of keywords/tags see the
                 libexif documentation. Auxdata can be read by the
                 import java script to gain more control over the
                 media structure.
                 Child tags:

<add-data tag="keyword1"/>
<add-data tag="keyword2"/>
...

                      Optional
                      If the library was able to extract the data
                      according to the given keyword, it will be
                      added to auxdata. You can then use that data
                      in your import scripts.
            A sample configuration for the example described above
            would be:
<libexif>
    <auxdata>
        <add-data tag="EXIF_TAG_MODEL"/>
    </auxdata>
</libexif>

          +
<id3>

            Optional
            These options apply to id3lib or taglib libraries.
            Child tags:
               o
<auxdata>

                 Optional
                 Currently only adding keywords to auxdata is
                 supported. The keywords are those defined in the
                 id3 specification, we do not perform any extra
                 checking, so you could try to use any string as a
                 keyword - if it does not exist in the tag nothing
                 bad will happen.
                 Here is a list of possible keywords:
                 TALB, TBPM, TCOM, TCON, TCOP, TDAT, TDLY, TENC,
                 TEXT, TFLT, TIME, TIT1, TIT2, TIT3, TKEY, TLAN,
                 TLEN, TMED, TOAL, TOFN, TOLY, TOPE, TORY, TOWN,
                 TPE1, TPE2, TPE3, TPE4, TPOS, TPUB, TRCK, TRDA,

<add-data tag="TENC"/>
...

                      Optional
                      If the library was able to extract the data
                      according to the given keyword, it will be
                      added to auxdata. You can then use that data
                      in your import scripts.
            A sample configuration for the example described above
            would be:
<id3>
    <auxdata>
        <add-data tag="TENC"/>

6.2.1. Online Content Settings

   This section resides under import and defines options for
   various supported online services.
<online-content fetch-buffer-size="262144" fetch-buffer-fill-size="0">

   Optional

   This tag defines the online content section.

   Attributes:
     *
fetch-buffer-size=...

       Optional
       Default: 262144
       Often, online content can be directly accessed by the
       player - we will just give it the URL. However, sometimes
       it may be necessary to proxy the content through MediaTomb.
       This setting defines the buffer size in bytes, that will be
       used when fetching content from the web. The value must not
       be less than allowed by the curl library (usually 16384
       bytes).
     *
fetch-buffer-fill-size=...

       Optional
       Default: 0 (disabled)
       This setting allows to prebuffer a certain amount of data,
       given in bytes, before sending it to the player, this
       should ensure a constant data flow in case of slow
       connections. Usually this setting is not needed, because
       most players will anyway have some kind of buffering,
       however if the connection is particularly slow you may want
       to try enable this setting.

   Below are the settings for supported services.

6.2.2. YouTube Service

   MediaTomb allows you to watch YouTube videos using your UPnP
   device, you can specify what content you are interested in, we
   will import the meta data and present it in the database, so
   you can browse the content on your player just like you do it
   with your local data.

   WANING:
          by using this feature you may be violating the YouTube
          service terms and conditions:
          http://www.youtube.com/t/terms

   Note:
          we do not download/mirror the actual videos, we only get
          description of the content and present it in the
          database. The actual video is only streamed when you
          press play on your device. So, when we use the term
          "retrieve videos" we actually mean retrieving the video
          name, description and associated meta data, not the
          actual flv file.

   Note:
          so far we have not yet seen many devices that will
          natively support the .flv format, you will need to setup
          appropriate transcoding profiles to make use of the
          YouTube feature.

<YouTube enabled="no" refresh="12600" update-at-start="yes" purge-after=
"1200000" racy-content="exclude">

   Optional

   Options and setting for YouTube service support, the attributes
   are:
     *
enabled=...

       Optional
       Default: no
       Enables or disables the service, allowed values are "yes"
       or "no".
     *
refresh=...

       Optional
       Default: 28800
       Refresh interval in seconds, each time the interval elapses
       we will contact the YouTube server and fetch new meta data,
       presenting the changes in the database view. This allows
       you to stay up to date with what is available on YouTube,
       you probably should not need to update more than once per
       day, so specify a reasonably high value here. Setting the
       option to 0 (zero) disables automatic refreshing.
     *
purge-after=...

       Optional
       Default: 0 (disabled)
       Time amount in seconds when data that has not been updated
       is considered old and can be purged from the database. This
       setting helps to prevent an endless filling of the database
       with YouTube meta data, the idea is the following: each
       video has a unique ID, during a refresh cycle the video
       meta data will be imported into the database and a time
       stamp will be added. Each refresh cycle we may encounter
       same content (i.e. nothing changed on the YouTube site), we
       will update the time stamp. However, if a particular video
       is no longer available on YouTube it will not be refreshed,
       once the time stamp exceeds the purge-after value we will
       remove the meta data for this particular video from the
       database.
     *
update-at-start=...

       Optional
       Default: no
       This option defines if we will contact the service right
       after MediaTomb was started (about 10 seconds after start
       up) or if data should be fetched when the first refresh
       cycle kicks in. It may be useful if you frequently restart
       the server and do not want the content to be updated each
       time. Allowed values are "yes" or "no".
     *
format=...

       Optional
       Default: mp4
       Selects the format in which the videos should be retrieved
       from YouTube.
          +
mp4

            A while ago YouTube also offers the videos in the mp4
            format which is playable by most players, it will also
            allow you to seek/pause.
          +
flv

            Flash video, obviously not a good choice if you want
            to play it on your UPnP device, only useful in
            combination with a properly set up transcoding
            profile.
     *
hd=...

       Optional
       Default: no
       If set to "yes", then a HD video will be retrieved if
       available.
     *
racy-content=...

       Optional
       Default: exclude
       Specifies if restricted content should be inclueded in the
       search results. The option will automatically be used with
       YouTube requests that support. By default restricted
       content is not included.

   Below are various options that allow you to define what content
   you are interested in.

   Note:
          all tags are optional and can occur more then once.

     *

6.3. Transcoding Settings

   The transcoding section allows to define ways on how to
   transcode content.
<transcoding enabled="yes" fetch-buffer-size="262144" fetch-buffer-fill-
size="0">

   Optional

   This tag defines the transcoding section.

   Attributes:
     *
enabled=...

       Optional
       Default: yes
       This attribute defines if transcoding is enabled as a
       whole, possible values are "yes" or "no".
     *
fetch-buffer-size=...

       Optional
       Default: 262144
       In case you have transcoders that can not handle online
       content directly (see the accept-url parameter below), it
       is possible to put the transcoder between two FIFOs, in
       this case MediaTomb will fetch the online content. This
       setting defines the buffer size in bytes, that will be used
       when fetching content from the web. The value must not be
       less than allowed by the curl library (usually 16384
       bytes).
     *
fetch-buffer-fill-size=...

       Optional
       Default: 0 (disabled)
       This setting allows to prebuffer a certain amount of data
       before sending it to the transcoder, this should ensure a
       constant data flow in case of slow connections. Usually
       this setting is not needed, because most transcoders will
       just patiently wait for data and we anyway buffer on the
       output end. However, we observed that ffmpeg will fail to
       transcode flv files if it encounters buffer underruns -
       this setting helps to avoid this situation.

   Child tags:
     *
<mimetype-profile-mappings>

       The mime type to profile mappings define which mime type is
       handled by which profile.
       Different mime types can map to the same profile in case
       that the transcoder in use supports various input formats.
       The same mime type can also map to several profiles, in
       this case multiple resources in the XML will be generated,
       allowing the player to decide which one to take.
       The mappings under mimetype-profile are defined in the
       following manner:
          +
<transcode mimetype="audio/x-flac" using="oggflac-pcm"/>

            Optional
            In this example we want to transcode our flac audio
            files (they have the mimetype audio/x-flac) using the
            "oggflac-pcm" profile which is defined below.
               o
mimetype=...

                 Selects the mime type of the source media that
                 should be transcoded.
               o
using=...

                 Selects the transcoding profile that will handle
                 the mime type above. Information on how to define
                 transcoding profiles can be found below.
     *
<profiles>

       This section defines the various transcoding profiles.
          +
<profile name="oggflag-pcm" enabled="yes" type="external">

            Optional
            Definition of a transcoding profile.
               o
name=...

                 Required
                 Name of the transcoding profile, this is the name
                 that is specified in the mime type to profile
                 mappings.
               o
enabled=...

                 Required
                 Enables or disables the profile, allowed values
                 are "yes" or "no".
               o
type=...

                 Required
                 Defines the profile type, currently only
                 "external" is supported, this will change in the
                 future.
               o
<mimetype>audio/x-wav</mimetype>

                 Required
                 Defines the mime type of the transcoding result
                 (i.e. of the transcoded stream). In the above
                 example we transcode to PCM.
               o
<accept-url>yes</accept-url>

                 Optional
                 Default: yes
                 Some transcoders are able to handle non local
                 content, i.e. instead giving a local file name
                 you can pass an URL to the transcoder. However,
                 some transcoders can only deal with local files,
                 for this case set the value to "no".
               o
<first-resource>no</first-resource>

                 Optional
                 Default: no
                 It is possible to offer more than one resource in
                 the browse result, a good player implementation
                 will go through all resources and pick the one
                 that it can handle best. Unfortunately most
                 players only look at the first resource and
                 ignore the rest. When you add a transcoding
                 profile for a particular media type it will show
                 up as an additional resource in the browse
                 result, using this parameter you can make sure
                 that the transcoded resource appears first in the
                 list.

                    Note:
                            if more than one transcoding profile
                            is applied on one source media type
                            (i.e. you transcode an OGG file to MP3
                            and to PCM), and the first-resource
                            parameter is specified in both
                            profiles, then the resource positions
                            are undefined.

               o
<hide-original-resource>no</hide-original-resource>

                 Optional
                 Default: no
                 This parameter will hide the resource of the
                 original media when sending the browse result to
                 the player, this can be useful if your device
                 gets confused by multiple resources and allows
                 you to send only the transcoded one.
               o
<accept-ogg-theora>no</accept-org-theora>

                 Optional
                 Default: no
                 As you may know, OGG is just a container, the
                 content could be Vorbis or Theora while the mime
                 type is "application/ogg". For transcoding we
                 need to identify if we are dealing with audio or
                 video content, specifying yes in this tag in the
                 profile will make sure that only OGG files
                 containing Theora will be processed.
               o
<avi-fourcc-list mode="ignore">

                 Optional
                 Default: disabled
                 This option allows to specify a particular list
                 of AVI fourcc strings that can be either set to
                 be ignored or processed by the profile.

                    Note:
                            this option has no effect on non AVI
                            content.

                    #
mode=...

                      Required
                      Specifies how the list should be handled by
                      the transcoding engine, possible values are:
                         @
"disabled"

                           The option is completely disabled,
                           fourcc list is not being processed.
                         @
"process"

                           Only the fourcc strings that are listed
                           will be processed by the transcoding
                           profile, AVI files with other fourcc
                           strings will be ignored. Setting this
                           is useful if you want to transcode only
                           some specific fourcc's and not
                           transcode the rest.
                         @
"ignore"

                           The fourcc strings listed will not be
                           transcoded, all other codecs will be
                           transcoded. Setting this might be
                           useful if you want to prevent a limited
                           number of codecs from being transcoded,
                           but want to apply transcoding on the
                           rest (i.e. - do not transcode divx and
                           xvid, but want to transcode mjpg and
                           whatever else might be in the AVI
                           container).
                 The list of fourcc strings is enclosed in the
                 avi-fourcc-list section:
                    #
<fourcc>XVID</fourcc>
<fourcc>DX50</fourcc>

                      etc...
               o
<agent command="ogg123" arguments="-d wav -f %out %in/>

                 Required
                 Defines the transcoding agent and the parameters,
                 in the example above we use ogg123 to convert ogg
                 or flac to wav.
                    #
command=...

                      Required
                      Defines the transcoder binary that will be
                      executed by MediaTomb upon a transcode
                      request, the binary must be in $PATH. It is
                      very important that the transcoder is
                      capable of writing the output to a FIFO,
                      some applications, for example ffmpeg, have
                      problems with that. The command line
                      arguments are specified separately (see
                      below).
                    #
arguments=...

                      Required
                      Specifies the command line arguments that
                      will be given to the transcoder application
                      upon execution. There are two special
                      tokens:
%in
%out

                      Those tokens get substituted by the input
                      file name and the output FIFO name before
                      execution.
               o
<buffer size="1048576" chunk-size="131072" fill-size="262144"/>

                 Required
                 These settings help you to achieve a smooth
                 playback of transcoded media. The actual values
                 need to be tuned and depend on the speed of your
                 system. The general idea is to buffer the data
                 before sending it out to the player, it is also
                 possible to delay first playback until the buffer
                 is filled to a certain amount. The prefill should
                 give you enough space to overcome some high
                 bitrate scenes in case your system can not
                 transcode them in real time.
                    #
size=...

                      Required
                      Size of the buffer in bytes.
                    #
chunk-size=...

                      Required
                      Size of chunks in bytes, that are read by
                      the buffer from the transcoder. Smaller
                      chunks will produce a more constant buffer
                      fill ratio, however too small chunks may
                      slow things down.
                    #
fill-size=...

                      Required
                      Initial fill size - number of bytes that
                      have to be in the buffer before the first
                      read (i.e. before sending the data to the
                      player for the first time). Set this to 0
                      (zero) if you want to disable prefilling.
               o
<resolution>320x240</resolution>

                 Optional
                 Default: not specified
                 Allows you to tell the resolution of the
                 transcoded media to your player. This may be
                 helpful if you want to generate thumbnails for
                 your photos, or if your player has the ability to
                 pick video streams in a particular resolution. Of
                 course the setting should match the real
                 resolution of the transcoded media.
               o
<use-chunked-encoding>yes</use-chunked-encoding>

                 Optional
                 Default: yes
                 Specifies that the content should be sent out
                 using chunked HTTP encoding, this is the default
                 setting for transcoded streams, because the
                 content length of the data is not known.
               o
<sample-frequency>source</sample-frequency>

                 Optional
                 Default: source
                 Specifies the sample frequency of the transcoded
                 media, this information is passed to the player
                 and is particularly important when streaming PCM
                 data. Possible values are: source (automatically
                 set the same frequency as the frequency of the
                 source content, which is useful if you are not
                 doing any resampling), off (do not provide this
                 information to the player), frequency (specify a
                 fixed value, where frequency is a numeric value >
                 0)
               o
<audio-channels>source</audio-channels>

                 Optional
                 Default: source
                 Specifies the number of audio channels in the
                 transcoded media, this information is passed to
                 the player and is particularly important when
                 streaming PCM data. Possible values are: source
                 (automatically set the same number of audio
                 channels as in the source content), off (do not
                 provide this information to the player), number
                 (specify a fixed value, where number is a numeric
                 value > 0)
               o
<thumbnail>yes</thumbnail>

                 Optional
                 Default: no

                    Note:
                            this is an experimental option, the
                            implementation will be refined in the
                            future releases.

                 This is a special option which was added for the
                 PS3 users. If the resolution option (see above)
                 was set, then, depending on the resolution an
                 special DLNA tag will be added, marking the
                 resource as a thumbnail. This is useful if you
                 have a transcoding script that extracts an image
                 out of the video and presents it as a thumbnail.
                 Use the option with caution, no extra checking is
                 being done if the resulting mimetype represents
                 an image, also, it is will only work if the
                 output of the profile is a JPG image.

7. Supported Devices

Attention Hardware Manufacturers:

   If you want to improve compatibility between MediaTomb and your
   renderer device or if you are interested in a port of MediaTomb
   for your NAS device please e-mail to: <contact at mediatomb dot
   cc>

7.1. MediaRenderers

   MediaTomb supports all UPnP compliant MediaRenderers, however
   there can always be various problems that depend on the
   particular device implementation. We always try to implement
   workarounds to compensate for failures and limitations of
   various renderers.

   This is the list of client devices that MediaTomb has been
   tested with and that are known to work. Please drop us a mail
   if you are using MediaTomb with a device that is not in the
   list, report any success and failure. We will try to fix the
   issues and will add the device to the list.

7.1.1. Acer

     * AT3705-MGW

7.1.2. Asus

     * O!Play

7.1.3. Conceptronic

     * C54WMP

7.1.4. Currys UK

     * Logik IR100

7.1.5. Denon

     * AVR-3808
     * AVR-4306
     * AVR-4308
     * S-52
     * ASD-3N

7.1.6. D-Link

     * DSM-320
     * DSM-320RD
     * DSM-510
     * DSM-520

   Some additional settings in MediaTomb configuration are
   required to enable special features for the DSM renderers. If
   you have a DSM-320 and are experiencing problems during AVI
   playback, add the following to the server section of your
   config.xml:
<custom-http-headers>
    <add header="X-User-Agent: redsonic"/>
</custom-http-headers>

   Further, the DSM-320 behaves differently if it thinks that it
   is dealing with the D-Link server. Add the following to the
   server section of your configuration to enable srt subtitle
   support:
<manufacturerURL>redsonic.com</manufacturerURL>
<modelNumber>105</modelNumber>

   It is still being investigated, but we were able to get
   subtitles working with a U.S. DSM-320 unit running firmware
   version 1.09

   Also, the DSM-510 (probably also valid for other models) will
   only play avi files if the mimetype is set to video/avi, you
   may want to add a mapping for that to the extension-mimetype
   section in your config.xml:
<map from="avi" to="video/avi"/>

7.1.7. Freecom

     * MusicPal

7.1.8. Haeger

     * OnAir (also known as BT Internet Radio)

7.1.9. HP

     * MediaSmart TV

   Users reported that after a firmwre upgrade the device stopped
   working properly. It seems that it does not sue the UPnP Browse
   action anymore, but now uses the optional Search action which
   is not implemented in MediaTomb.

   Playing OGG audio files requres a custom mimetype, add the
   following to the <extension-mimetype> section and reimport your
   OGGs:
<map from="ogg" to="audio/ogg"/>

   Also, add this to the <mimetype-contenttype> section:
<treat mimetype="audio/ogg" as="ogg"/>

7.1.28. Roku

7.1.32. Snazio

     * Snazio* Net DVD Cinema HD SZ1350

7.1.33. Sony

     * Playstation 3

   Firmware 1.80 introduces UPnP/DLNA support, add the following
   to the <server> section of your configuration file to enable
   MediaTomb PS3 compatibility:
<protocolInfo extend="yes"/>

7.1.34. Syabas

     * Popcorn Hour A110

7.1.35. T+A

     * T+A Music Player

7.1.36. Tangent

     * Quattro MkII

7.1.37. Telegent

     * TG100

   The TG100 client has a problem browsing containers, where item
   titles exceed 101 characters. We implemented a server-side
   workaround which allows you to limit the lengths of all titles
   and descriptions. Use the following settings in the <server>
   section of your configuration file:
<upnp-string-limit>101</upnp-string-limit>

7.1.38. TerraTec

     * NOXON iRadio
     * NOXON 2 Audio

7.1.39. Western Digital

     * WD TV Live

7.1.40. Vistron

     * MX-200I

7.1.41. Xtreamer

     * Xtreamer

7.1.42. Yamaha

     * RX-V2065

7.1.43. ZyXEL

     * DMA-1000
     * DMA-2500

   Some users reported problems where the DMA will show an error
   "Failed to retrieve list" and the DMA disconnecting from the
   server. Incresing the alive interval seems to solve the problem
   - add the following option to the <server> section of your
   configuration file:
<alive>600</alive>

   Additionally, the DMA expects that avi files are serverd with
   the mime type of video/avi, so add the following to the
   <extensoin-mimetype> section in your configuration file:
<map from="avi" to="video/avi"/>

   Also, add this to the <mimetype-contenttype> section:
<treat mimetype="video/avi" as="avi"/>

7.2. Network Attached Storage Devices

   We provide a bitbake metadata file for the OpenEmbedded
   environment, it allows to easily cross compile MediaTomb for
   various platforms. We have successfully tested MediaTomb on ARM
   and MIPSel based devices, so it should be possible to install
   and run the server on various Linux based NAS products that are
   available on the market.

   So far two devices are shipped with a preinstalled version of
   MediaTomb, community firmware versions are available for the
   rest.

7.2.1. Asus

     * WL500g

   Use the statically linked mips32el binary package that is
   provided on our download site.

7.2.2. Buffalo

     * KuroBox-HG
     * LinkStation

7.2.3. Excito

     * Bubba Mini Server (preinstalled)

7.2.4. Iomega

     * StorCenter (preinstalled)

7.2.5. Linksys

     * NSLU2

   Available via Optware.

7.2.6. Maxtor

     * MSS-I

   Either use the Optware feeds or the statically linked mips2el
   binary package that is provided on our download site.

7.2.7. Raidsonic

     * IB-NAS4200-B

   Use the statically linked binary armv4 package that is provided
   on our download site.

7.2.8. Xtreamer

     * Xtreamer eTRAYz

7.2.9. Western Digital

     * MyBook

8. Running The Server

   When you run MediaTomb for the first time a default
   configuration will be created in the ~/.mediatomb directory. If
   you are using the sqlite database no further intervention is
   necessary, if you are using MySQL you will have to make some
   adjustments (see Configuration section for more details). To
   start the server simply run "mediatomb" from the console, to
   shutdown cleanly press Ctrl-C. At start up MediaTomb will print
   a link to the web UI.

   Note:
          Internet Explorer support is limited and not yet
          finished. It is very difficult to support this browser
          because of a huge number of bugs in its javascript
          implementation. If you don't believe us - just visit
          http://selfhtml.org/ and see how often IE is mentioned
          in not following the specs or simply not working with
          certain functions and features. We recommend Firefox.

   If you want to run a second server from the same PC, make sure
   to use a different configuration file with a different udn and
   a different database.

   After server launch the bookmark file is created in the
   ~/.mediatomb directory. You now can manually add the bookmark
   ~/.mediatomb/mediatomb.html in your browser. This will redirect
   you to the UI if the server is running.

   Assuming that you enabled the UI, you should now be able to get
   around quite easily.

   We also support the daemon mode which allows to start the
   server in background, the --user and --group parameters should
   be used to run the server under an unprivileged account. A
   script for starting/stopping the server is provided.
