Adobe's RTMFP Profile for Flash Communication
Abstract
This memo describes how to use Adobe's Secure Real-Time Media Flow
Protocol (RTMFP) to transport the video, audio, and data messages of
Adobe Flash platform communications. Aspects of this application
profile include cryptographic methods and data formats, flow metadata
formats, and protocol details for client-server and peer-to-peer
communication.
