Description

In "7.4.3.3 Sequence parameter set RBSP semantics", maximum picture width and height in SPS should be a multiple of Max(8, MinCbSizeY) as well as picture width and height in PPS.

pic_width_max_in_luma_samples specifies the maximum width, in units of luma samples, of each decoded picture referring to the SPS. pic_width_max_in_luma_samples shall not be equal to 0 and shall be an integer multiple of Max( 8, MinCbSizeY ).

pic_height_max_in_luma_samples specifies the maximum height, in units of luma samples, of each decoded picture referring to the SPS. pic_height_max_in_luma_samples shall not be equal to 0 and shall be an integer multiple of Max( 8, MinCbSizeY ).

Another good catch! Since we have this updated constraint for pic_width_in_luma_samples and pic_height_in_luma_samples, we should also have this for pic_width_max_in_luma_samples and pic_height_max_in_luma_samples.
