USB Webcam on Raspberry Pi

[Tobi_innit]

Hi, i´m trying to get a Logitech C920 to run on my Printer. The Camera is connected to the Raspberry and is recognized as a device (Checked using: v4l2-ctl --list-devices). My Duet is Version 3.4.6 and RepRap is on 3.5beta2. I downloaded the Motion Version 3.4, as it was the latest one compatible with my Firmware versions. I tried installing it on my DWC (External Plugins) but it failed and displayed this error:

"InternalServerException in InstallPlugin: ArgumentException in InstallPlugin: Failed to install package libmicrohtipd12, package manager exited with code 100"
Any ideas? Thanks

Edit (Because I dont know how to answer topics): I changed the Firmware back to 3.4.6 which had motion, so I didn´t need to install it.

@Tobi_innit for starters you shouldn't be running different versions of the firmware.
DSF, DWC and RRF should all be the same, so I suggest you rectify that first

@Tobi_innit If you are running in SBC mode with the Duet image, and at least RRF 3.4 (DSF, DWC and RRF), Motion should already be installed. You just need to install the Motion plugin. See https://docs.duet3d.com/en/User_manual/Reference/DWC_webcam#motion-on-a-raspberry-pi-running-dsf

@droftarts @jay_s_uk I changed it to RRF 3.4 and the Plugin was there, thanks. But i still cant get it to run. I connected my USB Webcam, which the Pi recognizes as dev/video0 and tested the webcam by taking a picture with fswebcam, which worked. I followed the instructions until it said "Download the .zip file of the plugin without extracting it, using the version that matches the firmware version of your Duet, from Motion Webcam Plugin". Isnt the Plugin already there? (it was in my External Plugins in my DWC after changing to 3.4) or do i have to add something extra? I can click it but it won´t start. I also installed motion on the Raspberry to try it but it didnt change anything. Any idea what i´m missing?
