------- Additional Comments From Gabriel de Perthuis  2005-01-27 21:01 -------
I have a quite recent CVS:
2005-01-27  Ronald S. Bultje  <rbultje at ronald.bitfreak.net>

        * ext/ffmpeg/gstffmpeg.c: (plugin_init):
          Fix compile with debug disabled (#165250).

I have only one version of gst-ffmpeg installed. Other avi films play fine, this
one plays fine in MPlayer, so I can't see what's wrong here. I'm snice-ing totem
to a higher priority in case it was a resource problem.

What the "shaky playback" looks like, is that the image doesn't move for one
second, then moves fast for less than a second, again and again, while still
being in sync with the audio on average. I'm noticing the time display is
strange too, it jumps and sometimes goes one second backwards.

Here are samples of the debugging output, at level 2.
