+ the client on the flash
is too lazy to tear out the code now, but if we briefly create
connection = NetConnection()
Connect to the server connection .connect(<address of the recording application on the server>)
stream = NetStream(connection );
Attach a camera with a microphone to the stream stream.attachCamera(); stream.attachAudio()
Publishing stream .publish(<video file name on server>, "record");
After 30 seconds, close the connection stream.close() connection.close()
