I'm sorry, but you merged this deprecation in 2013. See ffmpeg commit
The commit even states it should have removed "all traces of its use",
but it looks like with the years more and more code was added to it,
seeing the removal commit 8933ac2079644fb09916f1875c569103aefe84b1 in
libav doesn't even feature the massive amount of code we have under this
deprecation wrapper in mpegvideo.
So basically, the functionality was deprecated, but then further
developed to the point removing it is almost impossible.
How the hell did this happen?
