[FFmpeg-user] Requesting colormatrix advice

[Phil Rhodes]

 Well, yeah, but we've been discussing x265, too, so it seemed worth asking.
I presume you're talking about this setparams filter:
https://ffmpeg.org/ffmpeg-filters.html#setparams-1

There aren't any examples of usage there, but it seems to do nothing but set the flags on the output data. I'm not sure how that would work out with various output file formats and codecs, which may have various different ways of including that information.
I'm not clear what the function of "color transfer," "color primaries" and "colorspace" is in that case.
