Since the 10.1.0 flash player, it is pretty easy to implement a live streaming multicast system using rtmfp and stratus. However, it seems there is a unfixed bug when trying to manipulate the streaming data from client side, say, save the streaming data to hard disk. Normally, the stream publisher should have the ability to specify the permission of the published data. As discussed in:

An "Error #2123: Security sandbox violation: BitmapData.draw" is given by flash player when trying to capture the incoming video.
Since the post is in year 2009, I am wondering does anyone has a new walkaround of this problem?
