David - do you know who to direct this to?

Comment 10

[David Flanagan [:djf]]

Our Forward Lock DRM implementation only supports images and audio files. Video files have been explicitly out of scope from the very earliest discussions of this feature.

The point of creating the FL app in gaia was to demonstrate that we could implement forward lock drm with adequate security and without adding DRM to gecko. Partners who need to extend the forward lock mechanism can do so based on our example.

Support for short videos should be reasonably straightforward to add, following the existing code for music files.  The implementation supports ringtones and songs. Songs are downloaded and then stored in an encrypted form on the sdcard. The music app has special code for requesting the decryption key and decrypting the songs as needed. The same thing could be done for short videos, but only if the file size was small enough to be decrypted in memory, since we don't have a way to do streaming decryption.

In any case, I suggest that this is a WONTFIX bug and reflects a failure of communication between us and our partners. It should not have come as a late surprise that we do not support forward lock for videos.
