For LAC we use icecast2 servers and a `dvgrab | ffmpeg2theora | oggfwd`

pipeline to send an A/V stream to it.
http://en.flossmanuals.net/FFmpeg2Theora/StreamingDV/
For conference streaming: http://dvswitch.alioth.debian.org/wiki/
For more /artistic/ projects: Pd-extended features [oggamp~] [oggcast~]

[pdp_icedthe~] [pdp_theonice~]
gstreamer can also send A/V to icecast:

`gst-launch videotestsrc ! theoraenc ! oggmux ! shout2send ip=...

port=... password=... mount=/test.ogg`

or

`... theoraenc ! oggmux ! fdsink | oggfwd server port password -p -g

"genre" -n "title" -d "description" test.ogv`
VLC features built-in camera capture and icecast/shoutcast support. It's

also one of the few FLOSS projects that supports QT capture on OSX: vlc

qtcapture://

--sout='#transcode{vcodec=theo,vb=128}:standard{access=shout,mux=ogg,dst=source:ICECASTPassword@server:port/mountpoint.ogg}'
In the not too distant future .webm will become a viable alternative,

but icecast2 does not yet support that OOTB on most distributions.

HTH,

robin
