【正文】 rresponds to the QP value delta for the picture with POC value n. Default is “”. Shorthand form is –m. TemporalLayerQPOffset_L0 Defines QP offset relative to the parameter QP for temporal layer 0. When this parameter is specified as the value other than 52, default hierarchical QP assignments in Table 2 are ignored, and the value QP+TemporalLayerQPOffset_L0 is assigned to all slices in the temporal layer 0. Default is 52. Shorthand form is –tq0. Page: 8 Date Saved: 20210124 TemporalLayerQPOffset_L1 Defines QP offset relative to the parameter QP for temporal layer 1. When this parameter is specified as the value other than 52, default hierarchical QP assignments in Table 2 are ignored, and the value QP+TemporalLayerQPOffset_L1 is assigned to all slices in the temporal layer 1. Default is 52. Shorthand form is –tq1. TemporalLayerQPOffset_L2 Defines QP offset relative to the parameter QP for temporal layer 2. When this parameter is specified as the value other than 52, default hierarchical QP assignments in Table 2 are ignored, and the value QP+TemporalLayerQPOffset_L2 is assigned to all slices in the temporal layer 2. Default is 52. Shorthand form is –tq2. TemporalLayerQPOffset_L3 Defines QP offset relative to the parameter QP for temporal layer 3. When this parameter is specified as the value other than 52, default hierarchical QP assignments in Table 2 are ignored, and the value QP+TemporalLayerQPOffset_L3 is assigned to all slices in the temporal layer 3. Default is 52. Shorthand form is –tq3. Entropy coding parameters SymbolMode Defines entropy coder to use. Value 0 is for lowplexity entropy coder (LCEC) and 1 for binary arithmetic coder. Default is 1. Shorthand form is –sym. SBACRD Defines use of bit counts from arithmetic coder in ratedistortion decisions. Default is 1 (true). Slice coding parameters SliceGranularity Determines the depth in an LCU at which slices may begin and end. A value of 0 means that slice addresses are LCU aligned. A value of 1 means that slices addresses may additionally be aligned with CUs that has a width and height that is one half of an LCU. (depth of 1). Values between 0 and 3 inclusive are permitted, provided that CUs at the given depth are of size 16x16 or larger. For 64x64 LCUs, this means that the maximum allowed SliceGranularity is 2 since that gives a CU of 16x16 which is the smallest allowed. Default is 0 (LCUaligned slices) SliceMode Enables slice coding. When set to 1, the parameter SliceArgument will specify the maximum number of CUs at a depth of SliceGranuarity in a slice. When set to 2, the parameter SliceArgument will specify the number of bytes in a slice. Default is 0 (no slices). SliceArgument Defines the maximum number of CUs or bytes in a slice depending on the SliceMode setting. Page: 9 Date Saved: 20210124 EntropySliceMode Enables entropy slice coding. When set to 1, the parameter SliceArgument will specify the maximum number of CUs in a slice. When set to 2, the parameter SliceArgument will specify the number of bytes (LCEC) or bins (CABAC) in a slice. Default is 0 (no slices). EntropySliceArgument Defines the maximum number of CUs or bytes/bins in an entropy slice depending on the SliceMode setting. Deblocking filter parameters LoopFilterDisable Flag to disable the loop deblocking filter. Default is 0 (false). LoopFilterAlphaC0Offset Defines alpha offset used in loop deblocking filter. Default is 0. LoopFilterBetaOffset Defines beta offset used in loop deblocking filter. Default is 0. LFCrossSliceBoundaryFlag Flag to enable inloop filtering across slice boundaries. When it is set to 1, in loop filtering can cross slice boundaries. When it is set to 0, in loop filtering cannot cross slice boundaries. Default is 1 (across). Coding tools parameters MRG Defines use of the merge mode. Default is 1 (true). ALF Defines use of the adaptive loop filter. Default is
