Webstream not starting/not reachable

Camera model
Z-Star Microelectronics Corp. Venus USB2.0 Camera

What is the problem?
The camera doesnt output a stream. I cant reach it remote (http://:8080) or on the pi itself(http://localhost:8080).

What did you already try to solve it?
I set the camera_usb_options="-r VGA -f 30 -y" (these settings are listet as supported on OctoPrint Community Forum)

Unfortunately I cannot verify if these settings work, because
./mjpg_streamer -i "./input_testpicture.so -r VGA" -o "./output_http.so -w ./www"
only outputs
-bash: ./mjpg_streamer: No such file or directory

I just noticed, that according to the webcamd.log, my setting didnt apply, although i have no clue why this is the case, i simple wrote camera_usb_options="-r VGA -f 30 -y" at the end of octoprint.txt .

Additional information about your setup (OctoPrint version, OctoPi version, ...)

I used the OctoPi Image to set up the Pi

OctoPrint version: 1.5.3
OctoPi version: 0.18.0

If you need aditional information please let me know.

Thanks in advance for any kind of help.

If you are using OctoPi, the URL ending in :8080 is incorrect, and should be http://your-ip/webcam/ instead.

thanks for the quick response.

I cant reach the stream through this page either, error 404.

404 is unusual, since that implies that it is broken somehow. There should be a page there.

Anyway, I looked at the log again and it is not finding the video device for the USB camera.

Try running lsusb, and also unplug and plug ulit back in then run dmesg | tail -n 20 and paste both the outputs here.

The camera is listed with lsusb

I think the problem is, that the camera_usb_opitons dont seem to apply(atleast the logs says so).

Also, I can see with ls /dev that the camera is labled "video1" but video1 isnt stated as a Video device by /var/log/webcamd.log.

pi@octopi:~ $ ls /dev | grep video

Hmm, that's strange because as far as I knew the webcamd service it logged any /dev/video* device. And video1 or video2 are not showing in your initial log. They should be.

Is the camera_usb_options line uncommented? It should default anyway to auto-detecting and using the first found video device (that works).

I don't have any more ideas at the moment for why the video device is not picked up by webcamd.
