This is a proof of concept RtmpClient based on Flazr (http://flazr.com/) created to run on Flash Player (AS3 + Sockets + ByteArray).
First of all. I did that code some time ago. I'm not working on it anymore, and it is just a proof of concept.
In order to use flash.net.Socket in a Flash sandbox environment, you need to have a flash socket policy server. Look at http://www.adobe.com/devnet/flashplayer/articles/socket_policy_files.html. Because of this restriction, this library might be more suited for AIR apps.
Why creating a AS3 RtmpClient if Flash supports it natively?
I did that experiment when I was trying to figure out some way to save video streaming to hd using only Flash Player.
Things that I got working on my tests:
var connectionConfig:String = "rtmp://rtmp01.hddn.com/play playpath=mp4:vod/demo.flowplayervod/buffalo_soldiers.mp4";
var video:Video = new Video();
var rtmpNetStream:RtmpStreamPlayer = new RtmpStreamPlayer();
rtmpNetStream.play(connectionConfig, video);
The play method receives a connection configuration like librtmp. http://rtmpdump.mplayerhq.hu/librtmp.3.html
Some videos will work, some others will not. Whatever, this library is just a proof of concept. :-)
