Our conditions force us to make video call between 2 rooms almost every day for learning and teaching.
We don't have a good Internet connection here.
However, we do have 2 long HDMI cables, 2 HDMI TV, 2 laptops.
So we are trying a very simple approach that is just connecting them like the following illustration.
Room A Computer ]-- HDMI Cable --> Room B TV
Room A TV Then on the 2 laptops, we just use a simple WebRTC like this one:
https://webrtc.github.io/samples/src/content/devices/input-output/
to stream the video & voice call to each other.
The WebRTC does have echo problems with computer built in microphone.
So my question is:
Does any free/open source offline software that can handle this streaming task better then WebRTC, or do you have any suggestions?
(PS: We have Ubuntu OS computers. Just in case, we can also borrow Mac computers).
Thanks HN.
