====== Stream Team Planning ======
Last edit --- //[[nettings@stackingdwarves.net|Jörn Nettingsmeier]] 2012/02/10 10:10//

== List of available gear ==

  * Sony HDR-HC1 cam, does 16:9 720i, mini-jack stereo mic in
  * Canon GL2 cam, 4:3 DV, Composite out, YC out, 4.2-84mm f1.6-2.9, mini-jack stereo mic in
  * two Canon Vixia HV30, does 16:9 1080p @ 30fps, f1.8-?, 6.1-61mm, mini jack stereo mic in (Jarek) 
  * 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]

== Missing links ==

  * one VGA-to-DV converter, DVI capability would be a plus
  * a fallback VGA-to-DV converter
  * loooooooong firewire cables
  * magic firewire line amplifiers

== 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://rg42.org/t/lac12|trailer drafts and code]]
  * 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)
