Taking a snapshot of an flv

Following my last post on 9-Slice items, here comes another nice one on Bitmap.draw() and the security sandbox.
Many people know the solution to this one, but i just found myself looking for it for too long, so here it goes :)

If you want to take a snapshot of a running Video object, you can't, you'll be alerted by the flash player that you are violating
the sandbox security. So how do we do it?
Easy as pie :)

video.attachNetStream( null );
bitmapData.draw( video );
video.attachNetStream ( myNetStreamObject );

Three very simple lines of code but that are hard to come by.

    This RTMP protection trick does not work with 9,0,115,0 Moviestar anymore. Also, this prevents taking snapshot of the any http-streamed FLV (non-protected).

    Thus, RTMP content is not compatible with Papervision3D, for example. Bitter by Adobe.
