Stratus – P2P Communication Using RTMFP and Flash 10

22 April 2009 | 26,414 views | 8 Comments

After doing some research on live broadcasting events using streaming video, I happened to come across a beta Adobe product called Stratus which builds upon Adobe’s RTMP. Not to confuse RTMP (Real Time Media Protocol) with RTMFP (Real Time Media Flow Protocol), RTMFP is a new communication protocol built by Adobe that will let users connect and communicate using P2P between multiple clients running a Flash or Adobe AIR application.

Stratus as defined by Adobe…

Stratus is a hosted rendezvous service that aids in establishing communications between Flash Players or Adobe AIR endpoints using RTMFP. Flash Player endpoints must stay connected to the server during the entire time of communications. Unlike Flash Media Server, Stratus does not stream video or support media relay, shared objects, or scripting. Stratus is being made available as a beta service through Adobe Labs to allow our developer community to begin building applications using RTMFP.

…which basically states that Stratus can be used in combination with Flash Media Server to allow for developers to easily connect a small amount of users (at the moment) directly instead of through the Flash Media Server using peer-to-peer technology.

Flash Media Server is built to support client to server communication. Stratus breaks free of that structure and allows client to client communication. This is a great starting point for Flash and P2P application development.

Unfortunately, this system was not intended to create an infinitely scalable MMORPG, although, there are some variables within the Stratus environment that will allow you to push the user limit over the default of 5.

Adobe’s first iteration of RTMFP is really only a taste of what is to come, and is only a glimpse into the Flash world of P2P.

Here are some tutorial resources I’ve put together. Feel free to leave any that you have also found helpful in learning how to effectively use Stratus.

    C++ RTMP Server PITA to set up compared to FMS

    Thanks for overview!
    I wonder if anyone was able to actually see Adobe Labs Stratus Sample Application working between 2 users behind NAT? WiFi router hooked up to some residential network on one end, and symmetrical setup on another.

    for the past month I have been developing a free multi webcam chat box based on rtmfp (stratus) & MySQL only. I now have a working beta version but the application needs soms serious testing. I can do that only with your help. I need some people at the same time in 1 room to test the bandwidth use and video quality. I have tried to optimize bandwidth as much as possible but I am curious what the result will be in real world conditions.
    You can post feedback, suggestions and bug reports on the site itself.

    Please be a good sport and give me a hand!


    Thanks a lot!
