[MPlayer-users] Create a raw (RGB) file from video

[A. Vel]

Apologies upfront if this has been answered before. I have spent good amount
of time on man page but couldn't find it (There are zillion options, I may
have missed it).

I am trying to convert a video sequence into raw video file. So far I found
this many options

mencoder <filename> -o a.avi -nosound -ovc raw

but still, I haven't found the option that I am going to tell mencoder that
this will be an RGB.

Can someone please?
Thanks
