Thanks Hank. I guess Flash is not going to solve my needs right now.

Sorry ahead of time if the following has been covered previously. I would like to make a client to client voice (and later video) application via the Red5 server. 1) Can I build the client GUI from the Red5 components without the need of the Flash player? Not likely. Anything is of course possible, its just software, but in practical terms you would need to be able to encode in FLV, the flash video format. The audio component of the FLV format is nellymoser, and I am not sure if there is an open source code for creating that format. But it would be ugly. 2) What exactly is the voice codec available in Red5? It looks like I can only create MP3 voice data. You cannot create MP3 data and stream it to Red5. The only reasonable way to capture audio with the flash client is to use the flash video encoding faclility in the player and just turn video off. Unfortunately you basically end up dealing with it in video format. Inside the FLV format is the spark or VP6 codec for the video, and nellymoser for the audio. So, no matter what, you will be sending Nellymoser wrapped inside FLV to Red5. The bad news is that there is not a good way to convert nellymoser into mp3. Actually, thats not true. For around $7500 you can buy something from nellymoser.com to do this. But you dont need it if you only want to allow flash clients to listen to the audio. If you wanted to ever make content available via mp3, that is currently not really possible. At least not with any commonly available tools. 3) Are there routines in Red5 to extract the raw audio from the RTMP stream to potentially convert the encoding? I wouldnt think so, but this is better answered by someone else. In any case, and "raw" audio would be nelly moser, not some uncompressed or public format stream. Regards, Hank
