tested, mapping works for fourcc.
most of the raw codecs have mapped fourccs, mapped fourccs are a hack
for vfw codecs that were hardcoded to only use certain fourccs.
the vfw will crash if given a fourcc it does not support.

fixing the raw codecs to not hardcode the fourcc would fix the need to
map. i added the ffmpeg raw codecs to work around this limitation.

from DOCS/tech/codecs.conf.txt:

"A second fourcc can also be given, separated
with a space. MPlayer will replace the original fourcc in the headers
with this one before opening the codec. It's useful for win32 codecs
checking for the fourccs."

>For me, -vc ffraw444P fails.

yes it fails here too. it works if you add 'out YV12' to the codec, but
the plane is shifted and you get ghosted color. i am not sure what
colorspace would make it work correctly.
