Description: I am not able to transcode to xvid with the latest version of ffmpeg on x86_64. For example:

[david@darkstar Video]$ ffmpeg -i Catching_Glasses_Explanation.flv -vcodec xvid -r 25 -b 312k Catching_Glasses_Explanation.avi

Seems stream 0 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 29.97 (30000/1001)
Input #0, flv, from 'Catching_Glasses_Explanation.flv':

Stream #0.0: Video: flv, yuv420p, 320x240 [PAR 0:1 DAR 0:1], 29.97 tb(r)

Unknown encoder 'xvid'
[david@darkstar Video]$

Transcoding to other codecs works, as far as I have checked, e.g. I get no errors with "ffmpeg -i Catching_Glasses_Explanation.flv -vcodec msmpeg4v2 -r 25 -b 312k -mbd 2 Catching_Glasses_Explanation.avi"


Additional info:
* package version(s)ffmpeg-20071204-1-x86_64.

Steps to reproduce: See above (the Catching Glasses Explanation flv comes from YouTube)
