Red5 stream Quality

I’m using the oflaDemo connection of the Red5 example files. I’ve recreated it in AS3. When I broadcast to the server, my subscribing connection always gets back the same resolution broadcast no matter what the broadcast resolution is.

Is there a way to increase the resolution on the server side of things? Right now it is outputting at around 380x280 and I would like to output at around 640x480.
