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.
