Hi all,
I have integrated AVC/H.264 ISMACryp support within the mpeg4ip project and
encountered the following problem:
According to the ISMACryp spec the mp4v box of an encrypted MPEG-4 Video
(simple) has to be substituted with the encv box with the esds box as child,
etc. When creating AVC-Content I have an avc1 box with avcC as child and no
esds box anymore. How does the box structure for an ISMA encrypted AVC file
looks like? I have an idea but couldn´t find any information in the specs.
Is it sufficient to create the encv box with the avc1/avcC boxes as
children? Or do I have to add the esds box, too ?
example:
...
stbl
stsd
encv
avc1
avcC
...
Thanks for your help.
Cengiz.
