Motion Snapshot Release 3.2.2 snap10

Things are moving fast. Proxy support is back in netcam code.
A few more bugfixes.

We invite people to participate in the discussion about how the Netcam code=
=20
should retry and when it should give up when a Netcam does not respond.

This is the next step in completing 3.2.2

Release Notes

3.2.2 snap10 - 05 Aug 2005

Development Release

Changes since 3.2.1

snap1
    * Pthread deadlock in motion 3.2.1 fixed (Angel Carpintero)=20

    * http lockup bugfixes and=20
<http://www.lavrsen.dk/twiki/bin/view/Motion/ConvertSignalToSigaction>http:/=
/www.lavrsen.dk/twiki/bin/view/Motion/ConvertSignalToSigaction=20
only for webhttpd (Angel Carpintero)
    * alg_draw_location: Use temporary variables to store the values used=20
in for() loops instead of compute them in each loop (Angel Carpintero).=20
<http://www.lavrsen.dk/twiki/bin/view/Motion/ImproveAlgDrawLocation>http://w=
ww.lavrsen.dk/twiki/bin/view/Motion/ImproveAlgDrawLocation=20

    * Small speed boost to the function draw_textn (Andrew Hamilton and=20
Angel Carpintero).=20
<http://www.lavrsen.dk/twiki/bin/view/Motion/DrawTextnImprovement>http://www=
.lavrsen.dk/twiki/bin/view/Motion/DrawTextnImprovement=20

    * Added two new conversion specifiers: %o for threshold and %Q for=20
number of labels. (Kenneth Lavrsen)
    * Improved the config file description for pre_capture to get people to=
=20
use small values (Kenneth Lavrsen).

snap2
    * Avoid Cleanup Segfault. Allocates filepath using strdup to avoid=20
segfault is target_dir parameter is not supplied in motion.conf. Moves out=
=20
from signal handler the cleanup for pipe and mpipe. (Angel Carpintero)=20
<http://www.lavrsen.dk/twiki/bin/view/Motion/AvoidCleanupSegfault>http://www=
.lavrsen.dk/twiki/bin/view/Motion/AvoidCleanupSegfault=20

    * Major code cleanup concerning signedness of chars all over the code=20
to allow compilation with gcc4.0 (like in Fedora Core 4) without any errors=
=20
or warnings. This will probably require that some of the not yet included=20
patches will have to be fixed because it it code all over the place that=20
has been changed. (Kenneth Lavrsen)

snap3
    * Changed the order of drawing the red mask in setup mode so that the=20
smartmask is drawn after the fixed mask (Joerg Weber).
    * Changed the configure script so that /usr/lib64 is also searched for=
=20
the presense of ffmpeg (should fix the problem with 64 bit machines)=20
(Kenneth Lavrsen).
    * Changed the configure script so that rpms can be made by normal=20
non-root users (Angel Carpintero, Kenneth Lavrsen).

snap4
    * Fixed the ffmpeg code so that Motion also compiles against libavcodec=
=20
build 4754 or later. (Per J=F6nsson)
    * Above change in configure script for 64 bit ffmpeg support also=20
implemented in the freeBSD configure (Angel Carpintero)
    * Webhttp control interface fixed so it also works in=20
<http://www.lavrsen.dk/twiki/bin/view/motion/motionrelease3x2x2snap10/twiki/=
bin/view/Motion/FreeBSD>FreeBSD=20
(Angel Carpintero)
    * Improved the display of fixed mask. It is now shown as grey instead=20
of red. This makes it easier to see the smart mask working when you also=20
have a fixed mask (Joerg Weber).
    * Netcam First Header patch. If an error with jpeg decompression=20
occured at connecting to a mjpeg streaming webcam, this patch skips this=20
jpeg and tries to decompress next jpeg up to MAX_HEADER_RETRIES (20) (Peter=
=20
Holik).=20

snap5
    * Small improvement in framerate accuracy (Peter Holik).=20
<http://www.lavrsen.dk/twiki/bin/view/Motion/FramerateAdjust>http://www.lavr=
sen.dk/twiki/bin/view/Motion/FramerateAdjust=20

    * Fixed a bug in the autobrightness algoritm (Per Johnsson)
    * Fixed a bug in the webhttpd code related to pan/tilt. Bug was=20
introduced in snap4 (Angel Carpintero, Kenneth Lavrsen).
    * Improved the labelling algoritm so that locate feature and tracking=20
features includes all labelled areas above threshold (Joerg Weber).=20
<http://www.lavrsen.dk/twiki/bin/view/Motion/ImprovedLabellingPatch>http://w=
ww.lavrsen.dk/twiki/bin/view/Motion/ImprovedLabellingPatch=20

    * Fixed bug reporting errors when creating symlink to last snap (Bill=20
Maidment)
    * Changed all use of localtime to localtime_r which is threadsafe=20
(Kenneth Lavrsen).
    * Implemented a modified version of the=20
<http://www.lavrsen.dk/twiki/bin/view/motion/motionrelease3x2x2snap10/twiki/=
bin/view/Motion/WebcamCompressInMemory>WebcamCompressInMemory=20
so that Motion no longer uses the tmpfile() function for buffering the=20
frames of the mjpeg stream (Peter Hollik).=20
<http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory>http://w=
ww.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory=20

    * Modified the=20
<http://www.lavrsen.dk/twiki/bin/view/motion/motionrelease3x2x2snap10/twiki/=
bin/view/Motion/WebcamCompressInMemory>WebcamCompressInMemory=20
patch so that Motion now supports the mjpeg webcam stream while being setup=
=20
for saving PPM images (Kenneth Lavrsen).=20
<http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory>http://w=
ww.lavrsen.dk/twiki/bin/view/Motion/WebcamCompressInMemory=20

    * Major clean-up of code in picture.c and webcam.c so that function=20
names and variable names are less confusing. Also added many comments in=20
picture.c (Kenneth Lavrsen).

snap6
    * Webcam code commented more (Kenneth Lavrsen)
    * New improved webcam feature. When you set webcam_motion on Motion=20
will now stream at 1 fps instead of none. When motion is detected the=20
webcam stream increases to the limit set in the config file. This change=20
makes the webcam_motion much more interesting. The previous function always=
=20
ended up with clients timing out. (Kenneth Lavrsen).

snap7
    * Implemented WebcamShortWriteHandling patch (Bill Brack)=20
<http://www.lavrsen.dk/twiki/bin/view/Motion/WebcamShortWriteHandlingPatch>h=
ttp://www.lavrsen.dk/twiki/bin/view/Motion/WebcamShortWriteHandlingPatch=20

    * Implemented the libjpeg-mmx patch. Installing the MMX version of=20
libjpeg can increase performance. Especially for machines with very little=
=20
CPU power. It only modifies the configure script. If you do not have the=20
libjpeg-mmx the configure script with ignore this and use the standard=20
libjpeg. Note that RPMs will be built without this (Peter Holik and Angel=20
Carpintero).=20

k/twiki/bin/view/Motion/LibJpegMmx=20

snap8
    * Small code cleanup in webcam.c and picture.c and .h for the webcam=20
code (Peter Holik and Kenneth Lavrsen)
    * Small code cleanup in motion.c for the variable holding the number of=
=20
microseconds since epoch. The old code worked fine but relied on an integer=
=20
overflow every 71 minutes. (Bill Brack and Kenneth Lavrsen)
    * Implemented a fix/work around to a bug related to building and=20
installing RPMs on Suse. (Paul Beltrani)=20

://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2005x07x14x212356=20

    * Small speed optimization in the creation of reference frame (Peter=20
Holik).
    * Complete rewrite of the Netcam code. Should fix many of the reported=
=20
and still open netcam bugs. This is first release in a snapshot. Expect to=
=20
find bugs. Testing is important. If you have a netcam please test this and=
=20
report bugs.=20

=20
log accept(): Socket operation on non-socket continuously written to syslog=
=20
(Kenneth Lavrsen).=20

    * Fixed memory leak in webhttpd related to use of strdup (Angel=20
Carpintero).
    * Improved the error reporting in the Netcam code and did a few minor=20
corrections and code cleansups (Bill Brack).
    * Implemented a much easier to use motion_log function which replaces=20
the calls to prinf and syslog. The implementation to actually use this has=
=20
been implemented in video.c and the Netcam code files. Rest will be in next=
=20
snap. This code change as no impact to the user (Bill Brack).=20

tp://www.lavrsen.dk/twiki/bin/view/Motion/ErrorLoggingEnhancementPatch=20

    * Fixed a bug in video.c so that VIDEO_PALETTE_GREY cameras now=20
actually work (Bill Brack).
    * Implemented the conversion of signal to sigaction which should be=20
more thread safe. Hopefully this still keeps Motion from making Zombies.=20
(Christophe Grenier).=20
<http://www.lavrsen.dk/twiki/bin/view/Motion/ConvertSignalToSigaction>http:/=
/www.lavrsen.dk/twiki/bin/view/Motion/ConvertSignalToSigaction=20

    * Added new feature: Double size text. A new config option=20
'text_double' can be set 'on' and this scales the text to double size.=20
Default is off. (Andrew Hamilton).=20

patches that are easier to integrate without too much manual editing.=20
(Kenneth Lavrsen)
    * Added the missing rotate feature in the new netcam code (Billl Brack)

Next Steps

    * A lot of testing of the brand new netcam code.
    * Implement retry schemes as discussed in=20
<http://www.lavrsen.dk/twiki/bin/view/Motion/NetcamRetryErrorDiscussion>http=
://www.lavrsen.dk/twiki/bin/view/Motion/NetcamRetryErrorDiscussion=20

    * Fix open bugs.
    * tuner_number will be introduced later when Motion eventually supports=
=20
V4L2. Will not be in 3.2.2.
    * Add the two new conversion specifiers to Motion Guide and man page.
    * Add the new option text_double to Motion Guide when releasing 3.2.2
    * Add the new option netcam_proxy to Motion Guide when releasing 3.2.2
    * Range checking of options - includes a complete redesign of how=20
options are loaded and changed via remote control. This redesign is mainly=
=20
making the code more robust and should be transparent to the user.

Known Problems

    * See the=20
<http://www.lavrsen.dk/twiki/bin/view/Motion/BugReports>http://www.lavrsen.d=
k/twiki/bin/view/Motion/BugReports=20
for open bugs.
    * The pwc-ioctl.h is for pwc version 9.0.1, 10.0.6 and 10.0.7a. If you=
=20
still use the pwc 8 series then you need to use the headerfile=20
pwc-ioctl.h-pwc8.0 (copy the pwc-ioctl.h-pwc8.0 over pwc-ioctl.h). This is=
=20
relevant for USB cameras using Philips chips.
