Hi all, I agree that video support in asterisk is quite .. umh.. how to say it.. not as good as it should. But i have never found the lack of the rtp headers to be a problem. Every info you need to rebuild the rtp header is in the asterisk frame.

The same issues apply to playing video out from a file, so it would be nice if it was all done without relying on RTP headers.
