VLC - the Video LAN Client

VLC is a very flexible framework - not only for A/V playback but also allows to capture (both desktop and cameras) and stream video.

Menu → File → Open Network & paste an URL found in the Yellow Pages.

Hint: Enable “loop all” mode to make VLC re-connect in case of network-hickups or short project dropouts.

This walkthrough may differ slightly depending on VLC version & Operating System. Generic Information can be found in the VLC Flossmanual.

• Menu → File → Open Capture Device or “Menu → File → Streaming/Export”
• Select input
  • Capture Device → adjust camera settings
  • Desktop → set boundaries, size & scaling
  • File → choose file from disk
• Streaming-method: Icecast, Shoutcast or HTTP
• Destination: source:inoutsource@av.theartcollider.org:8000/MyProjectName.ogg
  That basically means: user=source, password=inoutsource, server/host=av.theartcollider.org, port=8000, mountpoint=MyProjectName.ogg.
• Transcode:
  Video: Theora 128kb/s (or 96-1024 depending on your bandwidth; some VLC versions say “theo” instead of “Theora”)
  Audio: off or Vorbis 64kb/s (or 32-256 kbps)
  
• Encapsulation format : OGG
• Finish

of couse you can also launch VLC from the commandline. ie capturing a Camera on OSX:

vlc qtcapture:// --sout='#transcode{vcodec=theo,vb=128}:standard{access=shout,mux=ogg,dst=source:inoutsource@av.theartcollider.org:8000/MyProjectName.ogg}'
