That's a thought. I'll do that right after I win the lottery or
inherit from a Texan uncle, and hire Richard to do it (well, maybe I'd
have to sequester him in a room with no net, but well...)

Meanwhile, since I'm just a human like you guys, I committed the only
the AMD-64 part of the patch. I'll try to find a better solution for
the libavcodec part)
