In our case I hope it will only impact internal ffmpeg copy - initially I
ommited -L part of ffmpeg configure and ffmpeg complained about unability
to find lcms2

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.

So I guess by applying videofilter opts file to (image) media, in our case?

Ffmpeg.git should be able to detect it by setting demuxer flag, something I
hope to experiment with soon.
