[gst-devel] gstreamer interaction with Gnome

[Marco Ballesio]

Hi,

checking on the totem code (both Ubuntu 9.10 or Fedora 12) and it
always overrides the gstreamer-properties settings with pulsesink. Ig
you e.g. don't want to use pulseaudio in your CPU bound box you'll
have to either manually modify totem or not use it as well.

Are there any bugs in totem about this?

Regards
