Hackeriet has 3 permanent video devices:

• The “pinball” TV
• The “Hackeriet” TV
• A projector in the ceiling

Currently, the only semi-permanent way to control these is using Chromecasts. This is suboptimal for a variety of reasons, including:

• Latency in realtime settings
• Compatibility with certain types of equipment

If we were to install NDI receivers on these video devices, we'd be able to support a decent amount of realtime usecases in addition to more casual Youtube video playback.

Receivers

• https://dicaffeine.com/
  • Provides a significantly low bar-of-entry for getting NDI devices up and running, and managing them remotely
  • Runs like utter shit on our RPis – Low resolution mode must be used, and drops frames
  • Does however provide packages for Ubuntu: Should be possible to run with good results on NUCs, ThinkCenters etc.

Sources

• The DistroAV project provides NDI plugins for OBS, with support for Windows, Linux, and MacOS.
