Heh. The documentation is, as with most OSS projects, not the best way
to find out *all* the tricks that things are capable of. I found that
one out by reading the source. :)

OTOH, mplayer has significantly better documentation than most of the
packages out there. Oh, and if anyone wants to include my description
into the libavc-options.txt file, feel free.
