mpv's vo_vaapi is based on the mplayer-vaapi repo's (just as your
patches), but in addition to mpv's changes over mplayer in general, the
vaapi code has been heavily changed. mpv also doesn't recommend using
vo_vaapi at all, but prefer vo_opengl EGL interop instead. The vaapi
video output API is pretty crap and tends to be buggy. It doesn't
prevent tearing in all cases either. I don't think anyone at Intel
really cares about the output API.

But vo_vaapi.c still has a vaPutSurface() call. The only thing that
seems different is that mpv actually uses the src part of
calc_src_dest_rects?
