Camera model
C920 & C270
What is the problem?
I cannot get both these cameras to stream in octoprint, i have tried to check the Webcamd log but cannot see if anything is wrong and would appreciate if someone could cast an eye over it!
What did you already try to solve it?
I made a working copy of octoprint on a Pi4b, i then created a fresh install exactly the same way using Raspberry Pi imager 3 with a clean install of Octopi as per previous SD card.
I edited the various files as per the prevoius SD card so they should be identical.
When i run the 2nd copy i cannot get both streams to display. I have been over and over the setup files and they look identical to me. Printed and attached a copy of the Webcamd log.
Logs (/var/log/webcamd.log, syslog, dmesg, ... no logs, no support)

Help for input plugin..: UVC webcam grabber
The following parameters can be passed to this plugin:
[-d | --device ].......: video device to open (your camera)
[-r | --resolution ]...: the resolution of the video device,
can be one of the following strings:
QQVGA QCIF CGA QVGA CIF PAL
VGA SVGA XGA HD SXGA UXGA
FHD
or a custom value like the following
example: 640x480
[-f | --fps ]..........: frames per second
(camera may coerce to different value)
[-q | --quality ] .....: set quality of JPEG encoding
[-m | --minimum_size ].: drop frames smaller then this limit, useful
if the webcam produces small-sized garbage frames
may happen under low light conditions
[-e | --every_frame ]..: drop all frames except numbered
[-n | --no_dynctrl ]...: do not initalize dynctrls of Linux-UVC driver
[-l | --led ]..........: switch the LED "on", "off", let it "blink" or leave
it up to the driver using the value "auto"
[-t | --tvnorm ] ......: set TV-Norm pal, ntsc or secam
[-u | --uyvy ] ........: Use UYVY format, default: MJPEG (uses more cpu power)
[-y | --yuv ] ........: Use YUV format, default: MJPEG (uses more cpu power)
[-fourcc ] ............: Use FOURCC codec 'argopt',
currently supported codecs are: RGB24, RGBP
[-timestamp ]..........: Populate frame timestamp with system time
[-softfps] ............: Drop frames to try and achieve this fps
set your camera to its maximum fps to avoid stuttering
[-timeout] ............: Timeout for device querying (seconds)
[-dv_timings] .........: Enable DV timings queriyng and events processing
Optional parameters (may not be supported by all cameras):
[-br ].................: Set image brightness (auto or integer)
[-co ].................: Set image contrast (integer)
[-sh ].................: Set image sharpness (integer)
[-sa ].................: Set image saturation (integer)
[-cb ].................: Set color balance (auto or integer)
[-wb ].................: Set white balance (auto or integer)
[-ex ].................: Set exposure (auto, shutter-priority, aperature-priority, or integer)
[-bk ].................: Set backlight compensation (integer)
[-rot ]................: Set image rotation (0-359)
[-hf ].................: Set horizontal flip (true/false)
[-vf ].................: Set vertical flip (true/false)
[-pl ].................: Set power line filter (disabled, 50hz, 60hz, auto)
[-gain ]...............: Set gain (auto or integer)
[-cagc ]...............: Set chroma gain control (auto or integer)
