I want to use WebRTC over my Raspberry Pi zero 2 w with an external webcam, so that I can communicate to other raspberrys, computers or smartphones. Problem is, that I'm very new to this topic. I tried to follow the links I posted on the bottom of this question.

Till now, I should have installed everything recommended in these links. When I reach the raspberry over 192.168.XXX.XXX:8080 I can enter the start page. The "MJPEG Stream" works, but when I try to call over the WebRTC, with checkboxes enables in HW support and camera, nothing happens.

First I tried:

uv4l --driver raspicam --auto-video_nr
sudo service uv4l_raspicam restart

Then I tried it with lsusb to get the device id of my webcam and then

uv4l --driver uvc --device-id 328f:2013 --config-file=/etc/uv4l/uv4l-uvc.conf --driver-config-file=/etc/uv4l/uv4l-uvc.conf

but, when I then try to restart the service with sudo service uv4l_uvc restart: "Job for uv4l_uvc.service failed because the control process exited with error code. See "systemctl status uv4l_uvc.service" and "journalctl -xe" for details."

I'm stuck now and have no idea if this is at least the right direction. Can someone please help me get the WebRTC to work? I'm also thankful for every input on the topic in general.

Thank you in advance! Ferrys

In case of problems, there is also a "--external-driver" option in uv4l which makes uv4l use the uvc kernel driver (if loaded) instead of its own userspace version (see the uv4l core manual).
