Detailed Description

struct v4l2_ctrl_h264_scaling_matrix - H264 scaling matrices

@scaling_list_4x4: scaling matrix after applying the inverse scanning process. Expected list order is Intra Y, Intra Cb, Intra Cr, Inter Y, Inter Cb, Inter Cr. The values on each scaling list are expected in raster scan order. @scaling_list_8x8: scaling matrix after applying the inverse scanning process. Expected list order is Intra Y, Inter Y, Intra Cb, Inter Cb, Intra Cr, Inter Cr. The values on each scaling list are expected in raster scan order.

Note that the list order is different for the 4x4 and 8x8 matrices as per the H264 specification, see table 7-2 "Assignment of mnemonic names to scaling list indices and specification of fall-back rule".
