Comment (by Aras Pranckevicius):
This change (regression?) probably breaks many expectations and
scripts/pipelines that people might have.
E.g. ffmpeg's own wiki says "On ffmpeg command-line this is what options
such as colorspace and color_trc do; you can also put them on the output
side to modify what space the output is in"
(https://trac.ffmpeg.org/wiki/colorspace), but apparently now on the
"output side" they do nothing at all.
Likewise, Academy Sofware Foundation "encoding guidelines" page
(https://academysoftwarefoundation.github.io/EncodingGuidelines/Quickstart.html)
in all the ffmpeg command line examples puts color_trc and color_primaries
on the output side. I've spent quite some hours yesterday puzzled why
examples there do not work properly, before thinking of "let's try ffmpeg
6.0 instead of 7.1"
