mpv/libmpcodecs/vd_divx4.c
arpi 1864646717 I've found some time to implement the encoding support for the new 
DivX API. Now it's possible to play and encode movies with the
latest DivX release.
One thing that doesn't work is the new Video Buffer Verifier (VBV)
multipass encoding. The encoder segfaults. Maybe it just isn't
supported with the standard profile of the released binary encoder.
