---------------------------------+--------------------------------------
 The `-debug` options provide very usable information for e.g. H.264. For
 HEVC, none of these options seems to produce the intended output. Only
 highlevel header data is available.

 I especially miss the `-debug qp` feature.

 Everything is a lot simpler for H.264 and is handled nicely in
 mpegvideo.c. For HEVC the quadtree makes it a lot more complex...

 Summary of the bug:
 How to reproduce:
 {{{
 $ ffmpeg -debug qp -i input.hevc
 $ ffplay -debug qp input.hevc
 }}}
