[MPlayer-dev-eng] Re: mplayer UDP port number

[Marc Hoffman]

Ok what I have done is added a new video out driver for raw video 
dumping.

static vo_info_t info =
{
	"RAW file eyuv I420",
	"raw",
	"mmh",
	""
};

This has been done in much the same way that pgm files are dumped.

and to use it lets say you type

mplayer tennis.bits -vo raw

Do I just add this file, I don't think I have CVS ACCESS for 1 and 
secondly who reviews changes?
