------- Additional Comments From Jürg Billeter  2005-08-23 00:57 -------
Got exactly the same problem. It may have something to do with variable bit rate
movies where time_base is used for precision instead of frame rate. Precision
seems to be measured in frames/millisecond in ffmpeg while framerate is measured
in frames/second. The code in gstffmpegcodecmap.c doesn't seem to differentiate
between variable and constant framerate.

Both, the attached test case and my test video, are DivX 5 movies. They play
fine with gst-ffmpeg 0.8.5, ffplay, xvidcore.
