Yeah, I use both mplayer and mencoder. I believe it is possible handle
both at link time. The key seems to be avcodec_register_all() - if
mplayer built a different version of that file only, the unused
encoders should be properly left out at link time, without breaking the
mencoder built at the same time.

This should be doable with some sed magic, and making a
libavcodec_mplayer.a for mplayer to link with. No changes needed in
ffmpeg.
