Hi Anton,
I do agree with you. 
Please find the updated (and rebased) patch attached to this email.

Best,
Elias

P.S. By the way, I would be tempted  (I didn't do that here) to declare
the block_size field as 

const size_t block_size;

and then when setting it into av_video_hint_alloc(...) cast away the
const (it has to be assigned only once, upon allocation of the struct),
just to enforce compiler checking against accidental assignments and
for better clarity that this is a read-only field, in the general case.

P.P.S.: I'm sending the second part of the patch for libavcodec  as a
separate email.
