Class
GtkMediaFile
Description [src]
abstract class Gtk.MediaFile : Gtk.MediaStream {
parent_instance: GtkMediaStream
}GtkMediaFile implements GtkMediaStream for files.
This provides a simple way to play back video files with GTK.
GTK provides a GIO extension point for GtkMediaFile implementations
to allow for external implementations using various media frameworks.
GTK itself includes implementations using GStreamer and ffmpeg.
