I have 2 things to say about this. First is that IIRC, tiles and WPP are
mutually exclusive, so I would have expected your change to introduce dead
code. It might have been changed for a later profile, but I think ffmpeg's
decoder doesn't support this or these profiles. Anyway, I wonder what the
intent of that code was.
Which leads me to the second. FFmpeg decoder does not support tile
threading (the one it's based off does/did) so maybe this code never
mattered for FFmpeg.
Hesitant LGTM, as I find this fishy and wondering if I'm missing something
