Comment (by haasn):
As of 2cb0cebd11eb90dfcccac5c258af1003bd4f17d2, ffmpeg is capable of
parsing embedded ICC profiles and inferring the colorimetry tags.
Currently, this is not automatic, but must be manually requested by
inserting a `-vf iccdetect` filter.
Note that this relies on reasonably well-behaved ICC profiles - if the ICC
profile deviates too strongly from the set of known primaries and transfer
curve, the tags will remain as 'undefined'.
All ICC profiles used in practice should be well-behaved in this regard,
but YMMV.
