Are you referring to the choice of FLV_CODECID values?

Not only, you can find whole history on:
https://lists.ffmpeg.org/pipermail/ffmpeg-devel/
https://trac.ffmpeg.org/ticket/6389
https://trac.ffmpeg.org/ticket/3581

try play this sample in ticket
The objections mainly center on compliance with Adobe's spec which is a
concern when muxing.

no not only muxing, it’s format spec, and no documentation said which

codec id is hevc. 10?11?12?13?14?15? How do you make sure which one is
hevc
from users flv? This is very unreasonable.

By making it a user option: ffmpeg -f flv -hevc_id 12 -i rtmp://...
i do not think this can play all flv from other muxing, just private
demuxing, so why add it in ffmpeg? It is your private format, it can not
play all flv with hevc.

Is there a sample HEVC-in-FLV file for which this method won't work?
