It's actually 00 00 00 01 (four bytes) for the NAL units that we're dealing with here. To make this unambiguous, I would change the text to read
For H.264 the format MUST be that specified in ITU-T Rec. H.264 Annex B Byte stream format. agree, but we should still mention that its 0 0 0 1 + NAL as not every reader of nut.txt will have (or want) every spec of every codec ...
Fine by me. I just want the proper reference included for those that do have the document.
Actually, some NALs (PPS, SPS ?) can start with 00 00 01 IIRC. -- Baptiste COUDURIER GnuPG Key Id: 0x5C1ABAAA SMARTJOG S.A. http://www.smartjog.com Key fingerprint 8D77134D20CC9220201FC5DB0AC9325C5C1ABAAA Phone: +33 1 49966312
