Hi all
As others who already posted on this matter but got no
answers, I'm trying to get motion vectors from h264 codec
(P-frames).
Before v2, they seemed to be available in AVFrame::motion_val,
(along with motion_subsample_log2 and mb_type), which are now
deprecated.
Is there any way to get these values since v2 ?
(I'm also interested in getting back the dct_coeff for
I-frames, but something tells me that all these questions are
linked)
I think the general direction nowadays is to hide such internals.
If you want access to this stuff in the future you'll have to fork
and hack the functionality in

So i've understood, but I don't really see why these values are not
available anymore. I realize that messing with the internals of
various codecs is not why libav is made for, but these fields are
calculated anyway, so why not propagate it to the AVFrame ?
Because they're internal, and having them exposed hampers refactoring
efforts. If you want stuff to remain "like before" then just use some
specific old version of ffmpeg in your application (or even a specific
commit)
