This talk details our personal journey of creating a setup for video streaming at conferences, called mixos. We explain the challenges we faced and how Nix and NixOS helped us get the work done in a robust and efficient way. We do not consider ourselves extremely proficient in Nix, so any feedback from the community would be greatly appreciated.

In addition, we (as part of the FOSDEM video team) demonstrate how the same Nix-based setup can run on a FOSDEM video box.
