No camera stream since upgrade to bookworm

[dim burrow]

I upgraded my debian to bookworm and I dont get any camera picture

lsusb finds my Logitech C270 Webcam and settings seems to be correct.
How can I check where the problem is?

Ahh and everything is up to date

[twilit copper]

You did an inplace upgrade or reflash? If inplace, is this a RaspiOS?

How can I check where the problem is?
logs are always your friend

Also fix your tags #readme

[dim burrow]

I did an inplace upgrade it. Its an armbian OS with bookworm now

[dim burrow]

what should I change this to? I think mainsail (and maybe crowsnest) would be the best fit?

[twilit copper]

Only webcam

[twilit copper]

I don't recommend inplace upgrades for SBCs. Most of the times something breaks

[dim burrow]

I have no other option, as its storage is an EMMC and reader/adapters being currently on the way from china (so it needs like 3 weeks)

the crowsnest log is here

[twilit copper]

Then let us hope the best that nothing broke

[dim burrow]

I cant see too much wrong there

[twilit copper]

Look at the device:
/dev/v4l/by-id/usb-046d_0825_474A0520-video-index0 -> /dev/video4

[dim burrow]

Yes 😄 thats always the hype when doing something like that on a live system you need

[twilit copper]

Don't use the /dev/video but the /dev/v4l/by-id path

I like the Ditribution Info 😂

[12/18/23 11:50:56] crowsnest: Host Info: Distribution: Armbian 23.11.1 bookworm
Armbian 23.11.1 bookworm

Normally it shouldn't take 2 lines and shouldn't print twice the same thing

[dim burrow]

the worm in this book is becoming so big - I takes 2 lines

[dim burrow]

how did you find it that fast 😄

working now..

im just wondering, why the exact same config worked on armbian buster

[twilit copper]

I already got a few hundred cases. So I know what to look for ^^

[twilit copper]

You can run v4l2-ctl --list-devices to see what is blocking the other ports

[dim burrow]

Thanks @twilit copper you did awesome for me and probably for hundred others 😄 💪

[twilit copper]

Also an upgrade from buster to bookworm, that's pretty bald xD

[dim burrow]

yeah.. well if I alreads HAVE to upgrade (2 extensionsions needed at least bullseye)... then why only take 1 risk, if you can 2 ? 😄

btw... I always thought crowsnest is a must if you have a camera

I just read that crowsnest ist only needed when using multiple cameras..

does mainsail allow one camera already with no crowsnest at all?

[twilit copper]

Nope

[dim burrow]

ok, so crowsnest is still a must..
I read confusing comments on the voron forums

[twilit copper]

Overall you don't need crowsnest, you can run ustreamer and camera-streamer on your own, but crowsnest makes it easier.
Mainsail alone doesn't have a streamer to get a video stream

[dim burrow]

might /dev/video4 be a better option?

[twilit copper]

Some old setups or Fluidd still got mjpg-streamer, but that should be capable of multiple streams too. But it's really old, so I don't recommend it.
Or maybe they talked about spyglass?

[dim burrow]

at least video4 is also working

[twilit copper]

Like I wrote, don't use the /dev/video option. That can change. The other path won't change

[dim burrow]

ahh! now I understand !

great!

[twilit copper]

/dev/v4l/by-id/usb-046d_0825_474A0520-video-index0 -> /dev/video4
The v4l path is linking to the /dev/video path, so they are the same
