Picture header should be in its own NALU

The semantics of sh_picture_header_in_slice_header_flag state that:

When any of the following conditions is true, the value of sh_picture_header_in_slice_header_flag shall be equal to 0:

  • The value of sps_subpic_info_present_flag is equal to 1.
  • The value of pps_rect_slice_flag is equal to 0.
  • The value of pps_rpl_info_in_ph_flag, pps_dbf_info_in_ph_flag, pps_sao_info_in_ph_flag, pps_alf_info_in_ph_flag, pps_wp_info_in_ph_flag, or pps_qp_delta_info_in_ph_flag is equal to 1.

SLICES_A_HUAWEI_2 appears to not abide by this restriction as sh_picture_header_in_slice_header_flag is equal to 1 when pps_rect_slice_flag is equal to 0 (2nd IRAP frame).

Thanks for reporting this issue, and it is confirmed.

This bitstream exercises six layouts.
Each layout last for 5 frames and it is the second layout (the entire frame has only one raster slice) causes this issue in the SLICES_A_HUAWEI_2 package.

I have removed this layout in the newly generated bitstream SLICES_A_HUAWEI_3.bit using VTM-12.3.
