New Webcam stack + WebRTC + Logitech C920

[FlyingRatBull]

Camera model

Logitech, Inc. HD Pro Webcam C920

What is the problem?

MJPEG stream works but WebRTC doesn't

What did you already try to solve it?

• Use /webcam/control to test WebRTC in Firefox - player loads but shows no image (pressed play)
• Use /webcam/webrtc in Firefox - player loads but shows no image (pressed play)
• Use /webcam/webrtc in VLC - doesn't play, debug log:

  main debug: `http://anycubic-i3.local/webcam/control' successfully opened
  ps warning: garbage at input from 509, trying to resync...
  prefetch debug: end of stream
  

• journalctl -u camera-streamer-usb@default.service
