various notes on streaming.
use VLC to recode a network-stream (from an IP-camera or whatever) display and stream it via icecast:
vlc $STREAM_IN_URL --sout transcode{vcodec=theora,vb=300,venc=theora,width=320, height=240,fps=12}:duplicate{dst=display,dst=standard{access=shout, mux=ogg,dst=source:$IC_PASSWORD@$ICE_SERVER:$ICE_PORT/live.ogg}}" --sout-shout-name="$STREAM_NAME" --sout-shout-description="$STREAM_DESC" --sout-shout-genre="$STREAM_GENRE" --sout-shout-url="$STREAM_URL"
