Following are some logs coming from the ffmpeg mpeg4 decoder regarding
timestamps.  You can see for the logs for the working machine, the
timestamps are space roughly 0.04s apart, which is what you would expect
given that the source is 25fps.

You can see however for the logs for the problematic machine that the
timestamps are screwy.  Is this what you are talking about when you say "bad
timestamp"?  I am 95% certain that I am using the same versions of things on
both machines, since I'm simply installing from the ubuntu hardy
repositories, except that one is 32 bit and the other 64 bit (so the actual
binaries are different, but versions should still be the same).

But perhaps there is some way I can confirm the actual gst-ffmpeg version
being used?

Regards,
Jono
