I can't get crowsnest to display images from either webcam connected to the Pi Zero connected to my printer.
Attached are screenshots of my crowsnest.cfg and webcam settings in mainsail.
If it's relevant, both cameras are connected to the Pi via a USB hub. One camera is an old 2mp Trust webcam, while the other is a two year old GoPro Clone.
My Pi is setup with the following config.txt settings:

gpu_mem=16
arm_freq=1085
#arm_freq=1095 for my other unit with heatsink
gpu_freq=530
#gpu_freq=550 for the unit with a heatsink.
over_voltage=2
core_freq=515
sdram_freq=533
over_voltage_sdram=1

Fix your tags #readme

#

port 8079? Then you have to set http://<ip.of.your.pi>:8079/webrtc as your stream url

#

/webcam is for port 8080
/webcam2 is for port 8081
...

#

If that doesn't help send a crowsnest.log. It's possible that you made an update recently too and therefore broke camera-streamer

scenic urchin Dec 19, 2023, 5:05 PM

#

I updates crowsnest.cfg and the settings as shown in the attached images but no change.
I suspect something is wrong with my crowsnest install as the crowsnest.log hasn't updated since 3:30am this morning in spite of delete_log: true

📎 crowsnest.log

chrome oxide Dec 19, 2023, 5:07 PM

#

After your change of the config you can again use /webcam/webrtc. Just for the 8079 port you would have needed the full address

#

Your issue is also related to building camera-streamer manually. The underlying package libcamera got an update and that breaks the manually compiled version of camera-streamer. So this issue can happen again.
To fix it run:

cd ~/crowsnest
make update

scenic urchin Dec 19, 2023, 5:17 PM

#

Thanks I'll do that shortly.
Just to be clear on your first point, do I change the URL Stream text to literal "/webcam/webrtc" or "/GoProClone/webrtc" for the first cam? Accordingly do i use "/webcam1/webrtc" or "/Microdia/webrtc" for the second?

chrome oxide Dec 19, 2023, 5:18 PM

#

/webcam/webrtc literally

scenic urchin Dec 19, 2023, 5:25 PM

#

So using SSH and the KIAUH script rather than Mainsail Update Manager is what broke libcamera?

chrome oxide Dec 19, 2023, 5:26 PM

#

Nope

#

Package update

#

*system package

scenic urchin Dec 19, 2023, 5:27 PM

#

Forgive me being a noob... but "sudo apt update && sudo apt upgrade -y" broke it?

chrome oxide Dec 19, 2023, 5:27 PM

#

Yes

#

Like I described above libcamera was updated => camera-streamer broke
That's dumb but atm we cannot do anything about this

scenic urchin Dec 19, 2023, 5:31 PM

#

If I update the system in future, to be sure nothing is broken should I use KIAUH script to reinstall each package or is there a better method to safety check a system update?

chrome oxide Dec 19, 2023, 5:38 PM

#

Tbh, I don't know how kiauh updates ^^
I already asked the dev about it.
Overall it should be fine to update with kiauh and with the update manager inside Mainsail. Just don't update the system packages.
If you want to check the upgradable packages, you can run apt --upgradable or something like that. It's always written at the end of sudo apt update
If it list libcamera, you have to rebuild camera-streamer/run the command I sent.

#

After looking at your log again, you should update the device paths.
Use the /dev/v4l paths listed inside the log. Your cams are not at /dev/video1 and /dev/video2. Those /dev/video paths can also change after reboots

scenic urchin Dec 19, 2023, 5:40 PM

#

Gr8.. I'll do as you advise.

chrome oxide Dec 19, 2023, 5:40 PM

#

Another thing:

/dev/v4l/by-id/usb-0c45_USB20_Camera-video-index0 -> /dev/video2
Supported Formats:

        Size: Discrete 160x120

        Size: Discrete 640x480
```This device doesn't have a MJPG encoder. I don't know if it will work without that. Send the output of `v4l2-ctl --list-devices`

#

And to the camera-streamer thing. Just check your log. If it says ERROR: Start of camera-streamer [cam Microdia] failed! it's most of the times that problem with an updated libcamera. Another error leading to that output would be wrong custom_flags or wrong v4l2ctl parameters

scenic urchin Dec 19, 2023, 5:49 PM

#

I was testing both cams, but only need one to track my print status in Obeco. usb-0c45_USB20_Camera-video-index0 is a very old webcam I had lying around and at under 2mp I'm not sure it'll be high enough resolution for such a task. IAE I'll probably stick with the GoProClone and forego having to diagnose issues with the old camera.

#

My Pi is still updating, but I'll send the results of "v4l2-ctl --list-devices" shortly.

chrome oxide Dec 19, 2023, 6:08 PM

#

Oh it's a pi zero 2 right?
It could hang at ~84% if you are unlucky

#

If it does, you should stop all services:

sudo systemctl stop klipper
sudo systemctl stop moonraker
sudo systemctl stop crowsnest
```and then try again

scenic urchin Dec 19, 2023, 6:19 PM

#

Wow, you are amazing! I just checked the update and it's slowed almost to a halt at 85%, yet the mainsail interface is still updating so I'll just wait. I have a small overclock on the PiZ so I hope it will help push it to completion.

#

pytho@CTCi3ProB:~/crowsnest $ v4l2-ctl --list-devices
General Image Device: General I (usb-20980000.usb-1.2):
/dev/video1
/dev/video2
/dev/media0

USB20 Camera (usb-20980000.usb-1.3):
/dev/video0

#

I'm just waiting for my Pi to reboot to ensure all these changes have been applied.

#

Still not working. attached are images of updated crowsnest.cfg and webcam settings.

scenic urchin Dec 19, 2023, 7:53 PM

#

Here's the latest log:

📎 crowsnest.log

scenic urchin Dec 19, 2023, 8:20 PM

#

To simplify I removed the GoProClone from the configuration and left the older camera.
While there are no errors, there's also no image and a FPS of 0

📎 crowsnest.conf 📎 crowsnest.log

#

Could this be caused by the gpu_mem=16 or could it need custom_flags: or v4l2ctl: settings?

chrome oxide Dec 19, 2023, 9:28 PM

#

scenic urchin Could this be caused by the gpu_mem=16 or could it need custom_flags: or v4l2ctl...

no custom_flags and no v4l2ctl parameters used, so it can'Ät be that

#

And I already told you that that cam will make trouble

#

Set log_level: debug and send a new log

scenic urchin Dec 19, 2023, 9:29 PM

#

Should I single out the GoProClone to test this with instead of the old cam?

chrome oxide Dec 19, 2023, 9:30 PM

#

Yes, please

#

I looked again at the device. This is a Pi zero one?

#

Is this running only a cam?

#

I don't know if it's that capable tbh.

scenic urchin Dec 19, 2023, 9:43 PM

#

It is now

#

📎 crowsnest.log

chrome oxide Dec 19, 2023, 9:43 PM

#

The gpu_mem at 16 can be an issue. You might want to play around with that value

chrome oxide Dec 19, 2023, 9:44 PM

#

scenic urchin

That looks already promising

#

Does it work?

#

Don't forget to use /webcam/?action=stream and service mjpg inside Mainsail

scenic urchin Dec 19, 2023, 9:46 PM

#

Set gpu_mem to 128 and rebooted

#

I'm hoping the gpu_mem was not enough to display an image

chrome oxide Dec 19, 2023, 9:48 PM

#

It might be the CPU overloaded 🤷‍♂️

scenic urchin Dec 19, 2023, 9:50 PM

#

No luck I'm afraid... here's the settings for webcam

scenic urchin Dec 19, 2023, 9:50 PM

👍

#

I think I need to ask Father Xmas for a better Pi 😀

chrome oxide Dec 19, 2023, 9:52 PM

#

scenic urchin No luck I'm afraid... here's the settings for webcam

I had a look at your log again xD
You used port 8081, so the webcam is running on webcam1

chrome oxide Dec 19, 2023, 9:52 PM

#

scenic urchin I think I need to ask Father Xmas for a better Pi 😀

Is this pi also running your klipper or only the cam?

scenic urchin Dec 19, 2023, 9:53 PM

#

Both Klipper and Cam. Does the webcam string need to be "/webcam1/?action=stream"?

chrome oxide Dec 19, 2023, 9:55 PM

#

Does the webcam string need to be "/webcam1/?action=stream"?
Yes

#

Both Klipper and Cam
You won't finish even one print if the cam is running

#

I already had problems with just running klipper on the pi zero 1. It's just not powerful enough

#

So father Xmas will be your hero here ^^

scenic urchin Dec 19, 2023, 9:58 PM

#

Well at least the config and settings are now correct. Thanks for doing that for me.
Would the Zero 2 be adequate as I imagine the Pi 4 would be overkill if it's coping with just the Klipper ecosystem and a webcam?

chrome oxide Dec 19, 2023, 10:01 PM

#

Just a webcam he said 😂

#

The pi zero2 can be enough. There are quite some people out there with that setup according to the github issues.
The pi3 is the same chip but with more ram and an usb hub directly integrated.
But a pi zero2 should be enough as long as it stays at one cam.

#

I myself use a pi4, but I also use a picam and those really need some CPU power to run good
