draw NetStream from local video (flv) snippets

Hi,

The application is for iOS and plays FLV files on top of other graphic elements. While navigating through screens, a 'screenshot' is taken of the currentscreen  for a push transition. The image of the video should be part of that offcourse.

The videos are short and embedded into the application (client does not want to host them)

When drawing I get the infamous:

Error #2123: Security sandbox violation: BitmapData.draw: app:/WWWrapper.swf cannot access null. No policy files granted access.

I know about crossdomain.xml, and that some RTMP servers have settings for it, but I cannot find a way to do it here. To have access to the NetStream/Video for draw purposes.

Thanks in advance,

Manno
