I have no system ffmpeg in this case, and I care about startup speed
mainly. Using a shared ffmpeg may or may not help that.

Mplayer will never need to encode H.264, ROQ, AAC, Sorenson, etc ;)

The non-compressed audio encoding options and some image filter options
are necessary like you say, but most of them are not. They're included
wholesale.

Thanks, I'll add --disable-relocatable to my configure args.
