Tried 'ffmpeg -f image2 -i source.jpg file.avi' with a svn snapshot
of ffmpeg from yesterday (2008-03-21), and there are no problems
with it:  The brightness is preserved.

So it appears that there's a problem in the interaction
between mplayer and ffmpeg then?  This problem is not limited
to mf://*.jpg, by the way.  I've seen it happen with many other
ffmpeg codecs, such as ffh263.
