Ok we finally decided to switch to x264, quality looks a bit better and we are about 40-52kb/sec (384~-~512kbit/s). We was at about 5mbit/s before. This is a huge difference in both quality and feeling.
As sound quality is important in qw, i decided to not touch it. it's 128kbit 44khz now and will stay that way.
For the opengl question, in the future it's possible. however, i will never use ezquake for streaming 24/7 unless some big important game is on it's way and it's neccesary to show such graphic at all.
I can run more cams at the same time, but it makes no sense since all the sound will be mixed into DAC anway :|
Perhaps someone have time to fix the qwcl.x11/ezquake.x11/fodquake.x11 to make it run in a 8bit xorg server. Might take even less then with a suitable codec which supports 8bit (256 colours). [edit: fodquake-sw seems to run perfectly fine under 8bit configuration on some conditions]
Ofcourse, for big events, someone else is more than welcome to do the show.
* fixed sound quality
* fixed video quality.
* autotrack is ONLY turned on when griffin is not playing.

OpenGL on it's way. "The Big Games" will probably be in OpenGL. - please post good configurations for OpenGL and nice textures. Note that this machine is so utter crap, it will probably not work with higher resolution than 640x480 anyway :/
