VLC and mplayer need internal FourCCs because of their architecture.

FourCC are already split up for avi and mov. Apparently it got sabotaged at some point. A mux whitelist would be just as much as splitting the list. (Although having separate mux lists would be a good idea too.) Also here's an advice to FFmpeg: STOP ALLOWING USERS TO CREATE INVALID FILES. I'm sick of working them around. Stop creating a fucked up mess.
