Detailed Description

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.

Field Documentation

itu_t_t35_country_code

uint8_t AVDynamicHDRPlus::itu_t_t35_country_code

Country code by Rec.

ITU-T T.35 Annex A. The value shall be 0xB5.

Definition at line 247 of file hdr_dynamic_metadata.h.

application_version

uint8_t AVDynamicHDRPlus::application_version

Application version in the application defining document in ST-2094 suite.

CTA-861-H sets this to 1 for the HDR10+ payload carried in a Rec. ITU-T T.35 message.

av_dynamic_hdr_plus_from_t35() sets this field from the parsed payload. av_dynamic_hdr_plus_to_t35() ignores it and always writes 1.
