Well, the biggest mess is the MP_IMGTYPE_IP and MP_IMGTYPE_IPB stuff
which obviously most don't really understand since they are interpreted
differently in different places and also make it impossible for H.264
rendering to work. For all I know simply giving a buffer number in the
request would work much better (might be more problematic for a
(hypothetical?) device that can display buffers only in a round-robin
There are also things like having both MP_IMGFLAG_READABLE
MP_IMGFLAG_PRESERVE, seems somewhat questionable to me whether one makes
sense without the other...
