struct v4l2_ctrl_mpeg2_quantisation - MPEG-2 quantisation
Quantisation matrices as specified by section 6.3.7 "Quant matrix extension".
@intra_quantiser_matrix: The quantisation matrix coefficients for intra-coded frames, in zigzag scanning order. It is relevant for both luma and chroma components, although it can be superseded by the chroma-specific matrix for non-4:2:0 YUV formats. @non_intra_quantiser_matrix: The quantisation matrix coefficients for non-intra-coded frames, in zigzag scanning order. It is relevant for both luma and chroma components, although it can be superseded by the chroma-specific matrix for non-4:2:0 YUV formats. @chroma_intra_quantiser_matrix: The quantisation matrix coefficients for the chominance component of intra-coded frames, in zigzag scanning order. Only relevant for 4:2:2 and 4:4:4 YUV formats. @chroma_non_intra_quantiser_matrix: The quantisation matrix coefficients for the chrominance component of non-intra-coded frames, in zigzag scanning order. Only relevant for 4:2:2 and 4:4:4 YUV formats.
