Only artists like Cesar can produce art from garbage.
In signal processing, you can't produce anything better than
garbage-like stuff from garbage data.

I'd suggest trying a different decoder, i.e try to append -vfm ffmpeg
to see if you like that kind of decode better.


I am disillusioned enough to know that no man's opinion on any subject
is worth a damn unless backed up with enough genuine information to
make him really know what he's talking about.
