    Hi,

     

    Thanks for your interest in F4Fs..


    The official F4F specification is only available , as of now, through an NDA. The following thread gives all the details : http://forums.adobe.com/thread/685558

     

    Please let us know if you need more information on this.

    F4V is almost similar to the basic mp4 ISO specification. F4F is a fragmented version of the F4V where the audio/video data is stored in mutliple mdat files instead of a single mdat, so that the files can be delivered in chunks, and can be 'appended' while playback.

     

    Yes, if you are able to spec out your own F4f, i think you should be able to add DRM support much like what it is now.


    Thank you !

    Hi,

     

    Adobe Http Dynamic Streaming SDK already does simple fragmentation and fragmentation with DRM enabled using Flash access, which you are also trying to do. Can I have your contact so that someone from adobe can contact you.

     

    Thanks.
