[Red5] Newbie trying to get beyond 'ant server' broadcasting withred5 0.8

[Andy Shaules]

Well, something has to encode the video frames to a compressed format.
Something also has to form rtmp packets.

If you would rather not go through a browser, then I suggest to look at the 
hardware/device api and use xuggler to compress the frames into a suitable 
codec and wrap it into a rtmp stream.

You would think that more people have done this, but surpisingly not.

Good luck. The critical point to make this happen is getting a pointer to 
the pixel data using either interprocess communication or java api's.
