GTK UVC VIEWER (guvcview)

Basic Configuration

Dependencies:

Guvcview depends on the following:
- intltool,
- cmake,
- libsdl2 and/or sfml,
- libgtk-3 and/or libqt6,
- portaudio19,
- libpng,
- libavcodec,
- libavutil,
- libv4l,
- libudev,
- libusb-1.0,
- libpulse (optional)
- libgsl0 (optional)

On most distributions you can just install the development
packages:
intltool, autotools-dev, libsdl2-dev, libsfml-dev,
libgtk-3-dev or qt6-base-dev, portaudio19-dev, libpng12-dev,
libavcodec-dev, libavutil-dev, libv4l-dev, libudev-dev,
libusb-1.0-0-dev, libpulse-dev, libgsl0-dev

Build configuration:

guvcview uses cmake since version 2.2.1.

Basic usage:

mkdir build
cd build

(for Gtk3 ui) cmake --install-prefix=/usr -DUSE_SFML=ON ..
(for Qt6 ui) cmake --install-prefix=/usr -DUSE_GTK3=OFF -DUSE_QT6=ON ..

After configuration binaries can be build with 'cmake --build .'

To install guvcview and all the associated data files:
'cmake --build . --target install' (this may require root or sudo)

guvcview will build with Gtk3 support by default, if you want to use the
Qt6 interface instead, disable Gtk3 with -DUSE_GTK3=OFF and enable Qt6
with -DUSE_QT6=ON
Guvcview can be build with both Gtk3 and Qt6 support enabled, you can then
change the ui interface from the command line: 'guvcview --gui=gtk3' or
'guvcview --gui=qt6'
For the rendering engine you can use SDL2 (enabled by default) and/or
SFML (disabled by default), both engines can be enabled during configuration,
you can then choose between the two with a command line option '--render=sdl'
or '--render=sfml'.

Data Files:

(language files; image files; gnome menu entry)

guvcview data files are stored by default to /usr/local/share
setting a different prefix (--install-prefix=BASEDIR) during configuration
will change the installation path to BASEDIR/share.

Built files, src/guvcview and data/gnome.desktop, are dependent
on this path, so if a new prefix is set a make clean is required
before issuing the make command.

After running the configure script the normal, make && make install
should build and install all the necessary files.

guvcview bin:

(guvcview)

The binarie file installs to the standart location,
/usr/local/bin, to change the install path, configure
must be executed with --install-prefix=DIR set, this will cause
the bin file to be installed in DIR/bin, make sure
DIR/bin is set in your PATH variable, or the gnome
menu entry will fail.

guvcview libraries:

(libgviewv4l2core, libgviewrender, libgviewaudio, libgviewencoder)

The core functionality of guvcview is now split into 4 libraries
these will install to ${prefix}/lib and development headers to
${prefix}/include/guvcview-2/libname if -DINSTALL_DEVKIT=ON is used.
pkg-config should be use to determine the compile flags.

guvcview.desktop:

(data/guvcview.desktop)

The desktop file (gnome menu entry) is built from the
data/guvcview.desktop.in definition and is dependent on the
--install-prefix setting, any changes to this, must
be done in data/guvcview.desktop.in.

configuration files:

(~/.config/guvcview2/video0)

The configuration file is saved into the $HOME dir when
exiting guvcview. If a video device with index > 0,
e.g: /dev/video1 is used then the file stored will be
named ~/.config/guvcview2/video1

Executing guvcview

For instructions on the command line args
execute "guvcview --help" or "man guvcview".
