Re: Proposal for support of RTMP

About overhead I meant that there is RTMP inside RTMFP, RTMP itself has
overhead, so there is overhead in the end. I don't think Adobe is going to
open it anytime soon, and there is no RFC for it, while all other
protocols mentioned there are already standardized.

Alexey
