Detailed Description

Mastering display metadata capable of representing the color volume of the display used to master the content (SMPTE 2086:2014).

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

Note

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