This is **not** a script, only a bunch of commands collected here for convenience
Start icecast on the director's PC for the incoming webcam streams
/etc/init.d/icecast start
Start the feed-streams on the PCs/laptops where the webcams are:
- This is for V4L2 (USB webcams). We might need dvgrab or ffmpeg's iec61883-input for firewire-based cams
- This does NOT transmit audio. For V4L2 we need to find the correct ALSA-device and use that
gst-launch-0.10 v4l2src device=/dev/video0 ! ffmpegcolorspace ! video/x-raw-yuv,width=640,height=480 ! theoraenc quality=63 ! oggmux ! shout2send ip=regie port=12000 password=password mount=/cam1000.ogg

Thoughts about dependencies
All functionlities of krad are enabled by default
Some of them (GUI (station manager), xmms2, jack, wayland, x11, some codecs) can be disabled during
configuration
To disable, we use either "--without-FUNCTION" or "--disable-FUNCTION" (I don't care which :)
The build system will fail if a function has not been disabled but the dependency is missing
(just like today). There shall be no automagic like "If dependency is found on the system,
feature "xyz" will be silently enabled, otherwise it will be silently disabled"
