[Pkg-telepathy-maintainers] Bug#709951: Messed up video in xmpp calls

[Bas Wijnen]

Package: empathy
Version: 3.4.2.3-3
Severity: important

I'm trying to make video calls between two hosts, both running Empathy.  The
server is jabberd 1.4 from Debian.  The video behaves extremely weird.

- Sometimes everything works normally (but usually not for long).
- With one of my cameras, I get good video when not connected and in
  gstreamer-properties, but when connected to the other host, my own thumbnail
  shows garbage.  (There is also garbage on the other side.)  With a different
  camera, this does not happen.
- When in an audio call, and the other side of the connection turns on the
  video, _my_ camera's "active" LED lights up.
- When any of my cameras has transmitted some frames to the other connection
  and things go wrong, it will often alternate between two frames.  If I then
  turn my camera off, no response is visible on the other side (it will
  continue to alternate those two frames).  In some cases, one of the frames
  turns into my avatar (as would be expected when turning the camera off), but
  the alternating picture remains, just with one frame changed.

Especially the "garbage in my own thumbnail" and "camera mysteriously switches
on" problems make me suspect that this may be a bug in gstreamer.  Please
reassign if appropriate.

Thanks,
Bas
