New Revision: 14636

Modified:
   trunk/souffleur/GPlayer.py
Log:
Applied patch from Jo?\195?\163o Mesquita:
Changes the default playbin video sink to autovideosink with textoverlay.
This change was done because GStreamer does not support all
kinds of subtitles yet and I do not expect to be dependent
on GStreamer subtitle support development
