AVDynamicHDRPlus

This struct represents dynamic metadata for color volume transform - application 4 of SMPTE 2094-40:2016 standard.

To be used as payload of a AVFrameSideData or AVPacketSideData with the appropriate type.

@note The struct should be allocated with av_dynamic_hdr_plus_alloc() and its size is not a part of the public ABI.
