Its presence is not required by the video standard.  However, its presence may be required in some application-level specifications.

Subject: [Mp4-tech] H264: is access unit delimiter required?
Hello,
Regarding parsing of H264 stream...
Do I have to start from searching for Access Unit delimiter to read NAL unit? More to the point: is the Access Unit delimiter required by standard and is it common practice to use it?
Thanks,
-vl
