Please describe the problem:
When I try to play back a file recorded with mencoder using the following
command line:
/usr/bin/mencoder tv:// -tv driver=v4l2:alsa:amode=1:forceaudio:volume=100:\
                quality=100:amode=1:decimation=1:\
                height=540:width=768:freq=196.25 \
                -vf pp=hb:a/vb:a/dr:a/fd -ovc lavc \
                -lavcopts vcodec=h263p:vbitrate=4000:mbcmp=6:aspect=1.402 \
                -vf-add crop=720:540 -oac lavc \
                -o /home/simon/Downloads/test.avi -of avi

it doesn't get played back correctly. Irrespective of whether I use totem or a
pipeline build with gst-launch using the playbin, the video playback is far too
fast while the audio playback works ok.
If I uninstall gstreamer-ffmpeg, totem gives the following error message:

** Message: don't know how to handle video/x-h263, framerate=(fraction)25/1,
width=(int)720, height=(int)540

which makes me think that the framerate has been correctly read from the file.


Steps to reproduce:
1. create a video file using the command mentioned above
2. try to play it with mplayer -- works
3. try to play it with gstreamer -- doesn't work (see above)


Actual results:
While the audio track is played back with the correct speed, the video is far
too fast.

Expected results:
The video file should be played back correctly.

Does this happen every time?
Always

Other information:
Tried this on a x86_64 running Fedora rawhide

gstreamer-0.10.3-3
gstreamer-ffmpeg-0.10.0-0.gst.1.1
gstreamer-plugins-ugly-0.10.1-0.gst.1.4

Are there any additional information I can give?
