2c6811397b lavc: add profiles to AVCodecDescriptor
The profiles are a property of the codec, so it makes sense to export
them through AVCodecDescriptors, not just the codec implementations.

a853388d2f hevc: change the stride of the MC buffer to be in bytes instead of elements
Currently, the frame stride is passed in bytes, while the MC buffer size
is in int16_t elements, This can be confusing, so pass both strides in
bytes.

b1a32429ef hevc: Fix a53 caption extraction
Just realized my previous patch doesn't work quite right.  I uploaded a better
sample file that actually has visible captions to /incoming/hevc_cc.ts.  I
tested with that file doing hevc->x264 and it works.

This is basically an exact copy of the existing h264 logic.

94c0df79c7 lavc: propagate hwaccel errors
At least the new videotoolbox decoder does not actually set a frame if
end_frame fails. This causes the API to return success and signals that
a picture was decoded, even though AVFrame->data[0] is NULL.

Fix this by propagating end_frame errors.
