Stream Team Planning
Last edit — 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-compensated1), 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 overlays2). 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: 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)
