Raspberry Pi - WebRTC Stream Not Available

[SCH00N3R]

Hello,

I followed your instructions on installing camera-streamer to my Raspberry Pi. I can connect to the web interface and can see the /stream working. However, when I click on /webrtc I get a blank playback screen with an infinitely spinning wheel. Also, if I go to the control section, The Start WebRTC button is greyed out. What did I miss?

Thank you!

Same for me. On what RasbianOS version are you? cat /etc/os-release

Did you ever figure this out? Maybe its just me but the instructions wasn't very clear how to enable webrtc.

"The WebRTC is accessible via http://:8080/webrtc by default and is available when there's H264 output generated."

I'm using the precompiled binary and my service file looks like this:

`[Unit] Description=camera-streamer web camera for USB camera on Generic platform After=network.target

[Service] ExecStart=/usr/bin/camera-streamer

But when I click on the webrtc link, just the spinning loading bar.

Use --webrtc-disable_client_ice=1

Same issue here, --webrtc-disable_client_ice=1 has no effect.

More context:

• running on Raspberry Pi 3 (bookworm) with Klipper and Crowsnest
• "normal" Stream via Mainsail on /webcam/?action=stream works
• "normal" Stream via SSH tunnel directly on camera-streamer on /?action=stream works
• WebRTC also does not work if tunneling directly to camera-streamer, so it's not getting lost in mainsails nginx server.

... and the solution for me was adding gpu_mem=128 to the config.txt.

This IS documented, but without it the normal MJPEG streams still work, and there are no error messages whatsoever. So I noticed it just by chance.
