James Almer	61b27b15fc	avutil/hdr_dynamic_metadata: allow av_dynamic_hdr_plus_to_t35() to accept an existing buffer ... The function now accepts an existing buffer to avoid unnecessary allocations, as well as only reporting the needed amount of bytes if you pass a NULL pointer as input for data. For this, both parameters become input and output, as well as making data optional. This is backwards compatible, and as such not breaking any existing use of the function in external code (if there's any). Signed-off-by: James Almer <jamrial@gmail.com>	2023-04-05 09:47:12 -03:00

Mohammad Izadi	2744d6b364	Add HDR dynamic metadata struct (for SMPTE 2094-40) to libavutil ... The dynamic metadata contains data for color volume transform - application 4 of SMPTE 2094-40:2016 standard. The data comes from HEVC in the SEI_TYPE_USER_DATA_REGISTERED_ITU_T_T35.
