drm headers in mp4 encryption

Apr 11, 2012 12:44 AM

In flash access support for mp4 format, does mp4.header file alone is sufficient to a player to do a license request?

Do you have any specifications detailing the mp4.header file structure? or how flash access encryption is done for mp4 files?

 

Thanks,

Archana

    The Media Packager command line tool can generate a .header and a .metadata file when packaging content. The .metadata file can be used to initiate a license request from the player -- the .metadata file alone is sufficient to perform a license request.

     

    For information on the FLV/F4V file formats, you can download the video file format specification from http://www.adobe.com/devnet/f4v.html.

    No, the .metadata is not the same as the DRM Additional Header. For the DRMAdditionalHeader tag in the manifest, you need to use the contents of .header file (base-64 encoded) that was generated by the Media Packager command line tool.
