GTK 4 Sink & Paintable
GTK 4 provides gtk::Video
& gtk::Picture
for rendering media such as videos. As the default gtk::Video
widget doesn't
offer the possibility to use a custom gst::Pipeline
. The plugin provides a gst_video::VideoSink
along with a gdk::Paintable
that's capable of rendering the sink's frames.
The sink can generate GL Textures if the system is capable of it, but it needs
to be compiled with either wayland
, x11glx
or x11egl
cargo features. On
Windows and macOS this is enabled by default.
Additionally, the sink can render DMABufs directly on Linux if GTK 4.14 or
newer is used. For this the dmabuf
feature needs to be enabled.
Depending on the GTK version that is used and should be supported as minimum,
new features or more efficient processing can be opted in with the gtk_v4_10
,
gtk_v4_12
and gtk_v4_14
features. The minimum GTK version required by the
sink is GTK 4.4 on Linux without GL support, and 4.6 on Windows and macOS, and
on Linux with GL support.
The sink will provides a simple test window when launched via gst-launch-1.0
or gst-play-1.0
or if the environment variable GST_GTK4_WINDOW=1
is set.
Setting GST_GTK4_WINDOW_FULLSCREEN=1
will make the window launch in fullscreen
mode.
Flatpak Integration
To build and include the plugin in a Flatpak manifest, you can add the following snippet to your json manifest:
To generate the additional file gst-plugin-gtk4-sources.json
which will contain links to all the Cargo dependencies for the plugin to avoid making network requests while building, you need to use the flatpak-cargo-generator
tool from flatpak-builder-tools:
