Yeah, it should be possible using a special video out (vo) driver. I
think it's called "yuv" or something like that (get a list with
"mplayer -vo help").
I should work with a command line such as: mplayer in_file.vid -vf
my_filters -vo yuv
There might be some options you want to specify to this driver so that
it outputs the files in a certain directory, and start with a certain
string... but for that kind of thing, just read the man page, it's all
there! :-)
