Can't seek with gnonlin

Good to know, I'm doing it now.

After modifying gnlurisource properties, when I execute the following line:

the video is not displayed at all and nothing works.
If I don't commit the changes to gnlcomposition, the file is played
correctly.

Yes, the pipeline prerolls properly and the first frame is displayed.  After
receiving ASYNC_DONE I can play and pause without any problems.  The only
thing that doesn't work is seeking.


Anyway, I found that the problem be caused by EOS sent prematurely.  I can
see in the log that while seeking, after frame 39, gnlcomposition receives
EOS.  This would explain why I can't play the file after a seek attempt.


Any idea where to look for the source of the problem?  Playbin seeks the
same video file without complaining.
I am going to write C# bindings for GES and start using GES instead of
gnonlin directly, but it will take a while and I need something to work for
now.
