Octoprint will not receive video from my raspberry pi NoIR camera. It's an element14 1.3 rev camera. Octoprint runs just fine with my Logitech C170 and the video feed works. I am using a Raspberry Pi 3 Model B running Octoprint 1.3.9, flashed from OctoPi 0.15.1 using Etcher. I have expanded the filesystem. i have also made the necessary changes to /boot/octopi.txt.
The light on the Pi cam turns on when Octoprint boots up. when i SSH into the pi, i can run vcgencmd get_camera and receive supported=1 detected=1 so the camera is being detected. i ran sudo raspi-config and enabled the camera. I can also run sudo /etc/init.d/webcamd stop and the light on the camera will turn off, and i can turn it back on by running sudo /etc/init.d/webcamd start. I know the cables are plugged in correctly and i am using the correct port on the raspberry pi.
I have been using this set up to run my MP Select Mini V2 for months now and purchased the C170 because i was not able to fix this issue in the past. I realized how poor the picture on the c170 is and decided to attempt using the raspberry pi camera again to no avail.
Any help would be great!
The red LED comes on, which unless you've put the cable in correctly and haven't accidentally detached the lens from the PCB. Try grabbing a shot with "raspistill'; that will help narrow down the problem.

As you insert it, it should be oriented like this:
And for the Raspi, the contact side of the cable should point toward the end of the board on the side of the microSD connection.
Yup i have the cables connected correctly! as for using raspistill, this is the output of it.
pi@PrinterPi:~ $ raspistill -o cam.jpg mmal: mmal_vc_component_enable: failed to enable component: ENOSPC mmal: camera component couldn't be enabled mmal: main: Failed to create camera component mmal: Failed to run camera app. Please check for firmware updates
Did you enable the camera support using sudo raspi-config?
Yup! that was the first thing i did actually
Yeah my config file has all that jazz in it too
# Additional overlays and parameters are documented /boot/overlays/README
Enable audio (loads snd_bcm2835)
dtparam=audio=on
enable raspicam

tried increasing the gpu_mem value to 256 and im still not getting video feed and still getting the same error from raspistill
Alright, well you've diligently installed the sucker and endured any attempts to question that.
I think I'd check dmesg and look for any whining.
Given the error message you received, it might actually help to "update the firmware", a.k.a. sudo apt-get update && sudo apt-get -y upgrade.
From the actual code itself:
if (buffer->alloc_size < event->length) {
LOG_ERROR("event buffer too small (%i/%i)", buffer->alloc_size, event->length);
mmal_buffer_header_release(buffer);
return MMAL_ENOSPC;
}
It's all about GPU memory, it would seem. The log should indicate the length, though. This would suggest the GPU memory setting for this to be.
You might review /var/log/webcamd.log. Mine has the Pi NoIR v2 webcam, for what it's worth.

Joshua, what does this return?
$ vcgencmd get_mem gpu
I have a hunch.
running that exactly as you typed it out i get command not found
which vcgencmd
/usr/bin/vcgencmd
Makes me wonder if the start_x.elf actually ran.
If the config.txt that you gave us is verbatim, you have two lines that are comments and need to be prefixed with a comment:
# Additional overlays and parameters are documented /boot/overlays/README
# Enable audio (loads snd_bcm2835)
dtparam=audio=on

Goodbye...
Why is it trying to load up a USB-based camera? Maybe... unplug the Logitech?
If you ignore all the errors from the USB-based camera, it looks like the Raspi Cam is happy. Try unplugging the Logitech, rebooting completely and see if the Raspi Cam is now working.
i think i removed those comments for some reason, recommented the lines with no change
i'm not sure, i have had a c170 plugged in yesterday to test and see if it was working correctly, but hasnt been plugged in since
The timestamps looked so close. I assumed they were from the same session.
haha they shouldnt be from the same session, ive rebooted the pi half a dozen times today already haha. but yeah that logitech hasnt been plugged in for a while now
I think I would sudo systemctl stop octoprint to turn it off for a bit, kill mjpg_streamer with a pkill mjpg_streamer and repeat the raspistill from earlier.
Good thing I'm diligent like this: raspistill -o cam.jpg for me on a working rig produces what could be considered a false positive.
mmal: mmal_vc_component_enable: failed to enable component: ENOSPC
mmal: camera component couldn't be enabled
mmal: main: Failed to create camera component
mmal: Failed to run camera app. Please check for firmware updates
So of course, I'm also running the upgrade...
