As a casual developer/observer, I wonder about the consistency of the
options here with other parts of ffmpeg, in the general case it uses:
-color_primaries
bt709
unspecified
bt470m
bt470bg
smpte170m
smpte240m
film
bt2020
-color_trc
bt709
unspecified
gamma22
gamma28
smpte170m
smpte240m
linear
log
log_sqrt
iec61966_2_4
bt1361
iec61966_2_1
bt2020_10bit
bt2020_12bit
-colorspace
rgb
bt709
unspecified
fcc
bt470bg
smpte170m
smpte240m
ycocg
bt2020_ncl
bt2020_cl
For the colour range it has
-color_range
unspecified
mpeg
jpeg
The scale filter also has 'tv' and 'pc', it would be nice if there was
a canonical set to pull from, certainly from the command line user's
point of view. I had a hand in making some of those and I know I
didn't find a single source to use,
