When organising a DebConf, there are a number of things the local team needs to investigate so that the video team knows what to expect when they arrive to set-up. Most of these are physical constraints of the rooms hired, which makes pictures of the rooms and existing equipment useful.
The biggest question is how large the rooms are. This affects the Room setup. The positioning and number of power and network sockets as well as the speed of the network sockets are also crucial. If there are floor plans of the rooms, they make the planning of the setup much easier.
The minimum network we require for video streaming is a single static public IP that we can NAT behind. If we can get a range of IPs this makes things easier however. Our setup requires gigabit connectivity between all our machines.
Another consideration is how cables can be run between the front and the back of the talk rooms. This includes any local safety laws that may prevent us from running cables in specific areas or tape them down to the floor. If there is a false ceiling that cables can be hung from, this is often the easiest solution.
Often the chosen venue has some audio/visual equipment available for use to use in the talk rooms. What is available needs to be determined early on so that the hire list can be adjusted as needed.
The most important piece of equipment usually provided by the venue is one (or more) projector(s) in each talk room. These need to be able to take HDMI input, as this is what the Opsis outputs. They should also be of sufficient quality so that the image projected is clearly visible. If there are any switchers or range extenders between the computer input and the projector, these should also be identified.
The next useful pieces of equipment are speakers. We can hire these, but it is easier if the venue has a room PA that we can connect into. We require stereo (left and right) 3 pin XLR or balanced 1/4” jack line inputs that we can connect our mixer into.
Finally we need computers. These are usually easier to borrow from the venue than to hire. We need servers on site to handle encoding, storage and streaming as well as two desktops per room for capturing presentations and mixing the video.
