Hi all I resized and reencoded an avc file into mpeg4 using:
-ovc lavc -lavcopts codec=mpeg4:vbitrate=2400:v4mv:mbd=2:trell:cmp=3:subcmp=3:autoaspect:vpass=2 -vf scale=720:400

(from the documentation chapter 14.3.).
This did produce an avi file that was playable in mplayer only! I tried viewing it in vlc and further edit it in avidemux, but none of them was able to show the picture, only sound worked. I wanted it in the end to be played in my hardware divx player, which I did not attempt. I tried to change the fourcc from the ffmpeg one to DIVX, just in case, but that doesn't help.

Did I use an option unavailable to other mpeg4 codecs? Any help?

use -lavcopts vcodec=mpeg4
The defaults usually work best (and the output video is compatible with other players)
