gtk:media-stream-loop (object)

object -- a gtk:media-stream object
setting -- true if the stream should loop

The accessor for the loop slot of the gtk:media-stream class gets or sets whether the stream is set to loop. That is, restart playback from the beginning instead of stopping at the end.

Not all streams may support looping, in particular non-seekable streams. Those streams will ignore the loop setting and just end.
