MediaFile

abstract class MediaFile(val gtkMediaFilePointer: <Error class: unknown class><<Error class: unknown class>>) : MediaStream(source)

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 an implementation using GStreamer.
