Overview Cam Window doesn´t work on smartphone #99

Closed FalkoFuroro closed 1 year ago

The window opens but doesn't show anything. It works on Office PCs but not on Laptops or Smartphones.

Can confirm absence of a camera stream when opened under certain conditions, though the cause is quite elusive. I tested it with 3 devices:

  1. desktop PC at work
    • connected via local network: ✔
  2. smartphone
    • connected via eduroam: ❌
    • connected via home wifi: ✔
    • connected via mobile data: ❌
  3. desktop PC at home
    • connected via normal network: ✔
    • connected via VPN: ❌

I think we can conclude that it is certainly network depended, though not whether or not the device is located within the local network. Stressing the point that devices 2 and 3 were operated under identical settings other than the network, I have no clue what is going on here and am open for any suggestions.

Workaround found:

Use an ESP32 based camera, which use the socket.io server to distribute the stream instead of webRTC.
