Gtk.MediaFile
Description: Reference for Gtk.MediaFile

### 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.
