gtk:video-media-stream (object)

object -- a gtk:video widget
stream -- a gtk:media-stream object to play or nil to unset

Accessor of the media-stream slot of the gtk:video class. The gtk:video-media-stream function gets the media stream managed by object or nil if none. The (setf gtk:video-media-stream) function sets the media stream to be played back. The object argument will take full control of managing the media stream. If you want to manage a media stream yourself, consider using a gtk:picture widget for display.

If you want to display a file, consider using the gtk:video-file function instead.
