History

Sebastian Dröge c95e07a897 gtk4paintablesink: Improve scaling logic If force-aspect-ratio=false then make sure to fully fill the given width/height with the video frame and avoid rounding errors. This makes sure that the video is rendered in the exact position selected by the caller and that graphics offloading is going to work more likely. In other cases and for all overlays, make sure that the calculated positions are staying inside (0, 0, width, height) as rendering outside is not allowed by GTK.

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.

Flatpak Integration

To build and include the plugin in a Flatpak manifest, you can add the following snippet to your json manifest:
