| + | == 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.)), | ||
| + | |||
| + | 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:// | ||
| + | |||
| + | Robin has a collection of useful streaming scripts at [[http:// | ||
| + | |||
| + | Our network operations guy is Carr Wilkerson | ||
| + | |||
| + | == To do == | ||
| + | |||
| + | * create short intro trailer (CCRMA and lac logos would be nice, Fernando has some sound snippets) -- underway: [[http:// | ||
| + | * 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) | ||
