Webcam not working...
Hi there
I'm running Repetier-Server Pro 0.93.1 on a Raspberry Pi 4. (image from the website...)
I'm using a USB Cam called Razer Kiyo which has worked fine on Octoprint (on same Raspberry Pi 4)
I seems no matter what I do, I cannot get any picture to show up...
Some details from the cmd-line:
I have tried to use several of the listed resolutions and frame-rates in the setup...
Strangely this command reports no supported or detected cameras...
Seems like this works...?
This is what I see in the messages log... when I try to restart the webcam server... the resolution is strange... and it seems no matter that I put in the GUI, the desired resolution is always 0 x 0...
I have tried to download the latest server, recompile it "over the existing one"... but still no dice...
It's strange mostly because the cam worked fine with the Octoprint software... but I'm not sure if they use the same webcam server...
Is there anything else I can try?
I might give a total reinstall a try, but I suspect it will result in the same issue...
Any help is welcome...

I tried to re-image a new MicroSD card and reinstall everything...
Same result pretty much...
I have not recompiled the webcam server as with the previous installation...
Here is what I get.. from the cmdline...
Strangely it will not show anything here...
But it now shows one supported device, yet none detected which seems strange?
root@Repetier-Server:/home/pi# /usr/bin/vcgencmd get_camera
In the messages log I see the resolutiuon has now been "fixed"...
Every time I restart the webcam server the camera inits... it has a light "halo" which turns off and on every time... so it has some kind of contact with the camera...
Any other suggestions?
is only for raspi webcam, so for usb webcam ignore what it detects.
With our image you do not need to compile mjpg_streamer - we have included it with some automatic script to start it directly. In server webcam setup of printer you just select the webcam from list and assign it, which normally works. Port is 8080+ depending on number of webcams. Each gets a new port. Infos like resolution and framerate are all taken from our config file and can be changed in the same interface at the bottom. So please do not try your add mjpg_streamer solution on top - that will get conflicts with our autodetect/autostart scripts.
Your last log looks like it started correctly. When you say light goes on/off it sounds like it is restarting webcam. So look in the log further down to see why it disabled it. One reason might be if linux disconnected usb to reduce power drops. Before I go to deep into this you should say if you added own solution on top and what the log says about exit reason for mjpg_streamer.
