I appreciate your offer, but if you're getting the same error on the C615 this is probably not related to your other camera 
.
Can you tell me a bit about your Octoprint setup? Did you install from an OctoPi image? If so, what version. Also, what version of OctoPrint and MJpegstreamer are you running? Have you made any security/proxy changes to your server?
I broke my old installation, so I re-installed from Octopi 0.16.0. I’m not sure which version of mjpg-streamer I’m running; probably the one that came with the Octopi 0.16.0 distribution.
I haven’t made any changes to my networking configuration from default. No proxy for remote access or anything like that.
I have installed a 3.5” touch screen and TouchUI. I can try rebuilding with just the default 0.16.0 plus Octolapse and see if it works that way.
Definitely disable all of your other plugins at least. I need to try a fresh install with 0.16.0 as well. Perhaps something has changed with mjpegstreamer (shudder... lol!).
I'm running octoprint 1.3.10 on image 4.14.98-v7+ with a Raspberry pi 3B+, my webcam is a Logitech C615. I'm unable to change the webcam resolution. Any change I made in /boot/octopi.txt simply makes the webcam unavailable because of an error, the log says:
Starting up webcamDaemon...

When I check the webcam log, with default parameters, I see:

Now, I just kill the mjpg thread, cd to /home/pi/mjpg-streamer and run the same command again: this fails.
./mjpg_streamer: invalid option -- 'w'
When I strip the "faulty" arguments:
./mjpg_streamer: invalid option -- 'd'
./mjpg_streamer: invalid option -- 'f'
I already lost a stupid amount of time on this. Anyone can tell me what's going wrong?
You might try v4l2-ctl -D and v4l2-ctl --list-formats-ext as shown in this thread.
Searching for "logitech C615 mjpg_streamer raspberry pi" may find other useful resources.
It might be useful to note that the plugin TheSpaghettiDetective bypasses the octopi.txt file and changes are not applied, as stated in this thread:
This issue still persists.
The -q setting is not being read at boot.
When doing a "sudo service webcamd restart" it is being read, and image is changed accordingly.
I added this to my txt file
camera_usb_options="-r 1280x720 -f 30 -hf"
ps aux | grep stream

I have a Logitech C720
The image is still upp side down
Not all cameras support all the options. There's options in the UI for flipping/rotating if your camera doesn't support it.
okay, I was planing to stream the "raw" stream without needing anything that changes the settings.
There's also v4l2-ctrl that you could use (which the Camera Settings plugin uses).
Run the command v4l2-ctrl -d /dev/video0 --list-ctrls-menus and see what is reported - you may be able to flip it that way, but no guarantees.
I've seen some confusion about the -r switch with the input_uvc plugin: you can also specify some mode names, but they don't appear to be documented outside of the source code: mjpg-streamer/utils.c at 310b29f4a94c46652b20c4b7b6e5cf24e532af39 · jacksonliam/mjpg-streamer · GitHub

If nothing works try the -y and with smallers resolution! On my webcam the musb just crashes with higher resolution than 176x144.
Check dmesg if you got a problem
Also check the supported resolution using v4l2-ctl -d /dev/video0 --list-formats-ext
I spend a lot of time trying to figure out that
Hello, when I enabled the Custom Image Preferences, it only shows option to change JPEG quality (0-100) and nothing else. Anyone know how can I have the full settings instead? Camera is generic 1080P webcam that is shown as supported in Octoprint's list.
Hi all!
I start to configure webcam streaming and now I have choice of a soft for streaming from usb webcam.
I trayed the mjpg-streaming and it don't like me by several reason:
I made small python script (based on fork) that use ffmpeg and send pictures through http. the ffmpeg has enough options to made every needed convertation. The script stops the ffmpeg process if a http client is disconnected.
But now I want to use v4l2 driver directly to copy the driver buffer content to the http socket (without ffmpeg).
Yeah but you have to do at by hand
ssh into the pi and run
sudo service webcamd stop
to disable the cam an
sudo service webcamd start
to start the cam again.
I'm not sure if that can be done - or if it is already done that way - but the cpu utilization is pretty low for me. Less than 5% on my Pi 3+. I would guess about 3% on average.
@PrintedWeezl thank you for answer, but it not what I want. I think that the service should work all time but if has no requests by http from octo, camera shoud be disabled until new request will income
That's not possible with mjpg streamer.
It might be worth documenting the --softfps option, which limits FPS by dropping frames. It works for camera_usb_options, not sure about camera_raspi_options (I don't have one; a quick source search suggests it is not supported).
For my use, I'm more interested in resolution than frame rate. It seems that the -f option simply attempts to set the camera frame rate; my camera (Wyze Cam v2 with webcam firmware) seems to ignore that, and I always get the same frame rate (15fps). These frame rates overwhelm my Pi3 at higher resolutions. The --softfps option drops frames to achieve a target framerate (per the documentation), and achieves for me what I was hoping -f would do, limiting framerate to limit performance impact of using higher resolution.
The option isn't listed on the linked documentation page, but is described in the source:
Do you know if there's an option to disabe the fish eye?
