id,summary,reporter,owner,description,type,status,priority,milestone,component,version,resolution,keywords,cc 1439,IRAP constraint for Main 4:4:4 Intra profile,o.nakagami,,"The spec says (e.g. JVCTV-V1005-v1), in A.3.5, – In bitstreams conforming to the Main Intra, Main 10 Intra, Main 12 Intra, Main 4:2:2 10 Intra, Main 4:2:2 12 Intra, Main 4:4:4 10 Intra, Main 4:4:4 12 Intra, or Main 4:4:4 16 Intra profiles, all pictures with nuh_layer_id equal to 0 shall be IRAP pictures and the output order indicated in the bitstream among these pictures shall be the same as the decoding order. However, ""Main 4:4:4 Intra"" is not listed. I think this is a typo of the spec text and should be fixed as below. – In bitstreams conforming to the Main Intra, Main 10 Intra, Main 12 Intra, Main 4:2:2 10 Intra, Main 4:2:2 12 Intra, '''Main 4:4:4 Intra''', Main 4:4:4 10 Intra, Main 4:4:4 12 Intra, or Main 4:4:4 16 Intra profiles, all pictures with nuh_layer_id equal to 0 shall be IRAP pictures and the output order indicated in the bitstream among these pictures shall be the same as the decoding order. As a background, the issue is found on checking GENERAL_8b_444_RExt_Sony_1 which (not intentionally) includes TRAIL NAL in the Intra profile bitstream. If the text fix is agreed, the bitstream will also be revised. ",defect,closed,minor,,Text,,fixed,,bbross wjhan jct-vc@…
