So specifically, what are the features that you get with yaml that ffmpeg
doesn't already provide (that is: yaml is itself just a wrapper for other
stuff; what does it wrap that ffmpeg doesn't have already?). I see
h264enc/vp8dec/vp8enc/vp9dec/jpegdec/jpegenc vaapi. Anything else? Why not
just implement these in ffmpeg directly?

(Note that indeed, we did not link to libvpx to get vp9/vp8 decoding; we
wrote our own, and it worked _much_ better. That same may be true here
also.)
