Encoding

We use dvgrab to rip the talks from the camera and ffmpeg to encode.

Mirrors

• taurine (90 Mbps) [It can probably push much more if it were on a gigabit link]
• citric-acid (250 Mbps)

The list of mirrors can be found in caffeine:/var/www/mirrors.txt the web server selects a random mirror from this list at each file request. We now run Net-SNMP on all of our hosts, so we have real-time access to network and cpu load data. We should therefore be able to write a more intelligent mirror selection script. We also use mirror.cs to mirror on-campus.

We are currently looking at QoS tagging to reduce the load on campus switches/routers.
