  * one unidentified consumer cam (Fernando)
  * good tripod with Manfrotto head+leveling (CCRMA)
  * good tripod with Manfrotto head (no leveling) (Jarek)
  * a few crappy tripods
  * Sony Z-1 (robin) [backup solution only! needs x-atlantic transfer]
  * 1 magic DV repeater [[http://www.datavideo.info/en/DV%20Cables%20and%20Repeaters/VP-314|VP-314]] (Robin)
  * 2 x [[http://www.datavideo.info/en/DV%20Cables%20and%20Repeaters/VP-314|VP-314]] repeaters (CCRMA)
  * 2 x [[http://www.datavideo.info/en/DV%20Cables%20and%20Repeaters/2066|2066]] 66ft dv cables (CCRMA)
  * [[http://www.grassvalley.com/products/twinpact100|Twinpact100]] VGA-to-DV converter (CCRMA) ([[http://www.rcc.ryerson.ca/media/twinpact100manual.pdf|Twinpact user-manual (PDF)]])

== Missing links ==

  * a fallback VGA-to-DV converter
 
== Venues ==

  * one main room for the paper track (Campbell Recital Hall; will have to move somewhere else on the 14th)
  * one or two workshop tracks
  * concert (video optional, we want to stream B-format and stereo and maybe 5.1)

== Infrastructure ==

We're looking into dvswitch. Robin points out that network links are not latency-compensated((a fixed offset can be configured manually, but there are known drift and sync problems.)), so all cams must be hooked to the dvswitch machine directly. For the VGA capture, a netlink would be ok.

Jörn has been running current git with the liveMedia layer, and it seems to work as advertised.

No color correction, no scaling, currently no semi-transparent overlays((it is trivial to patch in overlay feature - robin has a working patch - the hard part is to expose it properly in the user-interface -- patch @ [[http://rg42.org/gitweb/?p=dvswitch.git]])). The latter should be simple because there is an auto-fade option already - all we need is a manual control.

Robin has a collection of useful streaming scripts at [[http://rg42.org/gitweb/?p=lac2011.git;a=tree;f=tools;]]

Our network operations guy is Carr Wilkerson  carrlane at ccrma .

== To do ==

  * create short intro trailer (CCRMA and lac logos would be nice, Fernando has some sound snippets) -- underway: [[http://download.linuxaudio.org/lac2012/]]
  * work out a way to receive and decode a B-format stream, perhaps including video
  * document this for users
  * set up a B-format test stream (loop)
