【正文】 e). SearchRagne’ = Round( SearchRange * ADAPT_SR_SCALE * abs( POCcur – POCref ) / RateGOPSize ) Quantization parameters QP Defines base value of the quantization parameter. Default is . Shorthand form is –q. MaxCUDQPDepth Defines max depth of a minimum CuDQP for subLCUlevel delta QP. Default is 0. RDOQ Defines whether ratedistortionoptimized quantization is used in the encoder. Default is 1 (on). DeltaQpRD Defines maximum QP offset at slice level for multipass slice encoding. In the encoder, each slice is tested multiple times by using slice QP values in the range [DeltaQpRD, DeptaQpRD], and the best QP value is chosen as the slice QP. Default is 0. Shorthand form is –dqr. MaxDeltaQP Defines maximum QP offset at largest coding unit level for blocklevel adaptive QP assignment scheme. In the encoder, each largest coding unit is tested multiple times by using the QP values in the range [MaxDeltaQP, MaxDeltaQP], and the best QP value is chosen as the QP value of the largest coding unit. Default is 0. Shorthand form is –d. dQPFile Defines file name containing list of QP value deltas. The nth line (where n is 0 for the first line) of this file corresponds 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
