50866c8d95 vp9: fix bugs in updating coef probabilities with parallelmode=1 
- The memcpy was completely wrong because
s->prob_ctx[s->framectxid].coef is a [4][2][2][6][6][3] array, whereas
s->prob.coef is a [4][2][2][6][6][11] array.
- The additional check was committed to ffmpeg by Ronald S. Bultje.

ba15aab4a4 libavformat/mtv: make clear we assume bpp is always 16 
All samples in the wild are RGB565/555 and we are already
acting on this assumption when pushing out the video frames,
so if we get anything != than 16 for bpp we just override
this value for doing any calculations making our approach
consistent.

Also avoid repeatedly shifting bpp.

padding) but if we haven't seen enough data then

as for the luma compoment for 4:4:4 streams. The Spec explicitly states
