Detailed Description

VVC Luma Mapping with Chroma Scaling Data Structure.

Host decoder sends in an array of VVC LMCS sets through one or multiple buffers which may contain 1 to 4 VALmcsDataVVC data structures in total. Each buffer contains an integer number of VALmcsDataVVC data structures with no gap in between. Driver may store the data internally. Host decoder may choose not to send the same LMCS data for each frame. When a VALmcsDataVVC structure carries a same value of aps_adaptation_parameter_set_id as a previously stored structure, driver should override the old structure with values in the new structure. VALmcsBufferType is used to send this buffer.
