    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 !

    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.
