Hi all,<br> I was using the qtdemux to get H.264 NAL Units. <br> <br> For few mp4 files, the first 4 bytes correspond to NumBytesInNalUnit and for few other the first 2 bytes tell the Nal Unit size. Is there a way to determine if the first 4 or the first 2 bytes give the size on Nal unit? <br>
<br> Also, is it possible to configure qtdemux to give Nal units with NAL prefix ( Annex-B of <em>14496-10</em> standard)<br><br>Thanks.<br><br>--vineeth<br><br>
