>the code overrides avctx->color_trc is from function
You must override it. HLG is signalled in ATC, VUI signals HDR, because
HLG has SDR layer that should be used to present SDR. That is the point.
Also ATC SEI is really only allowed in TS, i.e. in DVB-X2 applications.
One need to check whether HLG ATC SEI is even present in mp4 file. Will
do.
