Well, that only helps here if you replace mp_image everywhere by
whatever libavfilter uses, which means in the codecs, filters and vos.
Especially the last part means this might help to make the switch much
smoother (of course that's all just a theory ;-) ), if I find time this
change should allow me to implement the functionality that allows H.264
direct-rendering into -vo gl buffers, which would also help libavfilter.
