Little program which plays a file and reverses it after 10 seconds

I tried to reverse playback with playbin and it does work.
In my case, I need GStreamer Editing Service to insert files
in the timeline dynamically.

When I try to reverse, it seems like I receive an EOS message and
d3dvideosink render a 0 position, back to the beginning of the file, 
when I was at 10 seconds.

I think we have currently several issues:

 * compositor does not properly support reverse playback
 * audiomixer does not support at all reverse playback (the seek event is refused)
 * reverse playback has not been properly tested since GStreamer 1.0 and the port to NLE
Comment 2 Sebastian Dröge (slomo) 2016-08-17 18:49:55 UTC
On top of the dependant bugs (compositor, audiomixer, videorate, for the latter I have a WIP patch), there is also something going wrong inside GES with the seek event / segment handling.
