PiCam stream stopped working after a reboot

The Raspberry Pi camera worked properly until today morning. Currently I got the error

"Webcam stream not loaded"

If I check the webcamd status I get:

webcamd.service - the OctoPi webcam daemon with the user specified config
Loaded: loaded (/etc/systemd/system/webcamd.service; enabled; vendor preset: enabled)

Jul 08 17:57:18 octopi systemd[1]: Failed to start the OctoPi webcam daemon with the user specified config.

I get an appropriate response with the commands:
raspivid -v -o testvideo.h264 -t 5000
raspistill -v -o test.jpg
so I don't think it's a camera problem (Anyway I tried to replace the cable, but I got the same result).

Tried also to update and upgrade...

Any suggestion?

octoprint.log (25.4 KB)

/var/log/webcamd.log not found

I'm running octoprint 1.4.0 on Rasperry Pi 3B+

Edit 1:
I managed to get it to work with the commands:

git clone https://github.com/jacksonliam/mjpg-streamer.git
cd mjpg-streamer/mjpg-streamer-experimental
export LD_LIBRARY_PATH=.
make
./mjpg_streamer -i "./input_raspicam.so -fps 15" -o "./output_http.so"

So it's definitely not an hardware problem.

The question now is: what caused the previous problem? and how do I solve it? with this method the stream starts but I should write a script to lunch it at every reboot

Edit 2:
Doing a

sudo service webcamd restart
service webcamd status

I get this output:

Could my problem be related to the last line?

Edit 3:
I tried to set "raspi" (instead of "auto") in octopi.txt and now in journalctl -u webcamd

it seems to have been trying to start the webcamDaemon all day..

I feel your pain..
Same problem here, seems to be around the same time that happened.
I just installed a fresh Octopi and was happy seeing a video stream from my c270 in the Chrome Browser after reading a ton of stuff on the net and these forums when I couldn't get it to work in Firefox.
Then I rebooted and the image is gone ever since.
I can access the camera page, but I only get blank images for both snapshot and stream...

Hello @derZorn!

Firefox is quite over sensible with some things. You may try to disable the protection for the OctoPrint GUI with the little shield left to the address bar:

grafik

No problem, I use Chrome on most of my devices anyway.
The stream did work flawlessly on a number of devices including an Ipad , Notebook and Windows PC.
It just stopped for no reason that I can see.

So, since I am willing to solve that issue.
I started the whole process from scratch on another SD card.

  • I use a Raspberry Pi4b 2Gb.
  • use version '2019-09-26-octopi-buster-lite-0.17.0.img' to
  • freshly install on SD-Card as per instructions on octoprint.org
  • Camera works out of the box.
  • update to 1.4.0 as suggested by the screaming window on the top right
  • .. reload page
  • still working :slight_smile:
  • reboot Raspi
  • still working ! :smiley:
  • let's see what happens when I connect the Ender...

Ok, had a hunch and tried this....

  • turnig off the Raspi
  • cut the power
  • then boot again...
    Here's what it did look like before:
    `

And this is what I am seeing after I power down,cut the power and reboot..

What the ??
Any ideas ?

and another warm reboot later...

This is weird, and really unreliable. Why is this happening ?

Maybe a camera issue? Do you have another to test?

I fear I don't have another camera.
It seems the camera is not correctly recognized as chrome lists the webcam tab as 'webcam(640x480) .
The c270 should have an HD resolution (1280 x 720 px) .
So I set my
camera option in octopi.txt to reflect this.

camera_usb_options="-r 1280x720 -f 30"

after cold restart, I got a scrambled but widescreen image from the camera similar to the one above,
then I rebooted warm and the image is as intended...
Still weird, but I guess I can live with that for now.

I've been here before.
Now to connect the Ender...

My problem is different... I'm unable to start the webcam daemon properly...
The raspi cam has no issue it works but the daemon doesn't start and I can't see anything in the control tab

Sorry for somewhat hijacking your post, hope you find a solution to your problem and post it here.

After a fresh installation of OctoPi on another microsd every works again... I also restored a backup and everything seems to be ok...
Is there a metod to reinstall OctoPi without losing installations of other things (such as postgresql, multi-instance Octoprint, pyaes, scripts, etc.) it would take me a while to restore everything ... as long as I don't forget something...

[already tried to upgrade/downgrade, nothing happened]
