That FPS tho, @matrix (-; For devices more of the embed side like the PinePhone, I think a native video pointer (like what we had last #FOSDEM) would be much better job than two-way video conference.
Thinking about this, there should really be self-hostable service for one-way video stream (that is playable via one's favorite media player), plus low-latency audio conference: it would perform drastically better on lower-end devices and connections, e.g. for online learning.
