Don't forget... every supposed "end-to-end secure crypto" thingy that pushes pulls terminates stores into from or on an endpoint you don't control... is not secure, and often plundered in various manners by those with your best disinterests in mind. This generally includes all closed source commercial software. Wannabee Crypto AG's, NSA's, and backdoor corporate datapimps everywhere. "
What are the best-in-class video conferencing options for low-bandwidth situations?
Lines flapping or dropping packets is classic problem for streaming / interactive comms, downgrade is to use file xfer tools. Beware commercial services regarding cryptoprivacy. There are lot of tools for creating crypto private lans, anon nets, over IP to add that layer to standalone opensource apps where needed. If just low bandwidth, try testing point-to-point on lowest rate/quality codec option settings first, don't need 4K HDR just to talk and hold newspaper pages in front of camera. If at least one peer can handle being a hub, or threat model allows to rent some cheap shell host, then conference options open up. https://en.wikipedia.org/wiki/Comparison_of_instant_messaging_protocols https://en.wikipedia.org/wiki/Comparison_of_cross-platform_instant_messaging... https://en.wikipedia.org/wiki/Comparison_of_VoIP_software Tox, Jami, Matrix, Signal, Jitsi, Wire FreeSWITCH, Jingle Protocol Some people play with those, there are many tools, see what fits, have fun.
