Abstract: A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a slice and a plurality of adaptation parameter sets (APSs) including a plurality of APS types, wherein each APS includes an APS identifier (ID), and wherein APS IDs for the APS types are assigned in sequence over a plurality of different value spaces. The mechanism further includes decoding the slice using parameters from the plurality of APSs. The mechanism further includes forwarding the slice for display as part of a decoded video sequence.

Abstract: A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a slice and a luma mapping with chroma scaling (LMCS) adaptation parameter set (APS) including LMCS parameters. The mechanism further includes determining that the LMCS APS is referenced in data related to the slice. The mechanism further includes decoding the slice using LMCS parameters from the LMCS APS based on the reference to the LMCS APS. The mechanism further includes forwarding the slice for display as part of a decoded video sequence.

Abstract: A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a first adaptation parameter set (APS) network abstraction layer (NAL) unit including an adaptive loop filter (ALF) type, a second APS NAL unit including a scaling list type, a third APS NAL unit including a luma mapping with chroma scaling (LMCS) type, and a slice. The mechanism further includes obtaining ALF parameters from the first APS NAL unit, obtaining scaling list parameters from the second APS NAL unit, and LMCS parameters from the third APS NAL unit. The mechanism further includes decoding the slice using the ALF parameters, the scaling list parameters, and the LMCS parameter. The mechanism further includes forwarding the slice for display as part of a decoded video sequence.
