Well, in the patch I respected the current mapping, that is
WARN  -> DEBUG
FATAL -> ERROR
ERR   -> ERROR
V     -> INFO
DBG2  -> DEBUG
INFO  -> INFO

Is "WARN->INFO" the only needed change, or should some other mapping be
changed? Let me know, and I'll update the patch.

We currently have: QUIET, ERROR, INFO, DEBUG. To have a 1->1 mapping
with the levels used in libswscale, we would need to add FATAL, WARNING,
and VERBOSE. I think this would result in an ABI incompatibility, so I
am not sure if it is worth doing it.
Anyway, if we decide to add some debug levels I'd like to do it before
committing this patch (otherwise, I would have to change the libswscale
code 2 times :).

I did some quick tests with both mplayer and ffmpeg yesterday, and
things seem to be ok (if someone has some particular mplayer's command
line that I should test, let me know).

Ok, I'll prepare a separate patch for this.
