[MPlayer-users] IYUV fourcc

Hello.

I've run into a problem with mplayer trying to play clips encoded with 
IYUV, uncompressed. According to fourcc.org, the IYUV designation is a 
duplicate of I420. I never encountered the IYUV designation before. I 
suppose it would have be nice if mplayer recognized aliases or 
duplicates and translated internally to use the I420 it supports. 
However, I couldn't find any option that tells mplayer to use I420 as an 
overriding fourcc code. Does anybody have any ideas on how I might go 
about playing this?

Thanks.
