In ffplay, the “-debug vis_mb_type” doesn't work
I want to try options mentioned here: https://trac.ffmpeg.org/wiki/Debug/MacroblocksAndMotionVectors
I tried ffplay -debug vis_mb_type my-file.mp4, but it only showed a lot of console output. Here is the related part:
[NULL @ 01f55270] [Eval @ 05b5f12c] Undefined constant or missing '(' in 'vis_mb_type'
[NULL @ 01f55270] Unable to parse option value "vis_mb_type"
[NULL @ 01f55270] Error setting option debug to value vis_mb_type.
What can be the cause? I use the self-compiled ffplay, maybe I did something wrong, but overwise it works fine.
The related code is in libavcodec/mpegvideo.c, according to What do the numbers and colours represent for -vismv and vis_mb_type in ffmpeg?

That option along withvis_qpwas disabled in Mar 2017. Use the codecview filter.

-vf codecview=qpdoesn't work either. Doesn't look like there is a replacement forvis_mb_type.

For me with ffmpeg 4.1 the way to do it (which I guessed by reading the output of ffmpeg --help filter=codecview) is to explicitly set the qp flag to true, i.e. -vf codecview=qp=true.
