Octoprint with Logitech C905 webcam problem

What is the problem?
I have a Logitech C905 webcam connected to my raspberry pi3 running octoprint. Sometimes the webcam works, sometimes not. There is no pattern to when it works and when it does not. Lately it is not working 9 times out of 10 and is not usable at all.

What did you already try to solve it?

Being total noob to Ocptoprint command line, I tried googling for similar problems and found no solution. Found the webcam model to work with 800x600 resolution and 10fps (https://github.com/foosel/OctoPrint/wiki/Webcams-known-to-work) for other people, still, it's not working for me.

When I do a cat /var/log/webcamd.log, I get the following result:

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)

OctoPrint version 1.3.10, OctoPi version 0.16.0, Ender3, Marlin 1.1.9

Hello, I did some additional digging into this issue and am pasting some logs from a successful octoprint boot and an unsuccessful octoprint boot. During the successful boot the camera came online and was working, with the unsuccessful one it did not.

I am struggling to understand the logs and what I should do, to make the camera work all the time. Any advice please?

This is info from the failed boot sessions:

on previous octopi system (named prusaprint) the cam worked and I didn't have

i: select() timeout
 i: cleaning up resources allocated by input thread

current system is fresh 0.16.0
prusa print was from 2018-03-13

I will try to install old octopi from 2018 or 2017

I confirm that in older images cam works fine out of the box:

0.14.0
0.15.0
0.15.1

cam works still ok if I update octoprint to newest version 1.3.11

I checked once again:

On fresh install 0.16.0 cam is not working anymore

@madzur:

Could you please try previous version of octopi (0.15.1) to confirm if it is the same bug?

While you're testing different images you could test the new nightly build.

Maybe it works again on buster :slight_smile:

Just tested 2019-06-24_2019-06-20-octopi-buster-lite-0.17.0.zip

same as in 0.16.0, cam is not working

I'm not sure if the problem is with mjpg streamer or linux itself.
Maybe a dmesg log could help
Could you post one of a failed webcam start?

It is possible that this version sees more cams, and doesn't select proper cam

Only one real cam is connected to Pi

But in some logs before only one was detected and still wasn't working so probably not this

Well if thats the case it seems that it's not linux kernel related.

I thought the

errors could be related.
When I googled them I found several people that had issues with the logitech cam (also on x86 systems).
But it looks like that are errors of the control options like focus.
A few said after installing the uvcdynctrl package they got it solved. But I'm not sure if it means they got controls or the cam working.
You could try it if you want.

The next thing I would try is to build a new mjpg streamer. Here's a quick tutorial (scroll down to the webcam part).

If those things don't work I'm out of ideas for now
Sry :confused:

Looking at your original log, ioctl complains of not having the right configuration. I would check on the linux side of things. AFAIK, octopi doesn’t mess with raspbian configurations.

If using an older image and updating octoprint works, then google for your webcam and the raspbian release instead of being octoprint specific about the issue.

Hope that helps.

I recently merged an update to the webcam script - can you specify which nightly exactly you are using (use the latest date in the file name zip file)? So I can figure out if its genuine buster that is broken or just the new script?

Thanks

@qqgg231 I’m happy to report that on 0.15.1 the camera works on every startup. Thanks for that!

Now only to find out, what went wrong in 0.16.0, so that it kills the functionality randomly. I tried to follow the conversation below your post, unfortunately, I’m out of my depth there in terms of my linux knowledge :slight_smile:

Thank you for testing :slight_smile:

Currently I have no time for this, but I will probably want to test it in future, so we can know what is causing it

That last dist-upgrade now will install Raspbian Buster. Some have indicated that this will break OctoPrint.

Good to know, at that time sudo dist-upgrade updated only 2 packages including ffmpeg, so it was not big change

That's the sudo apt-get upgrade part. The dist-upgrade goes for the full Stretch-to-Buster major release upgrade.

I guess you have to change your sources lists first before a full dist-upgrade to buster works.
But I'm not sure if they have a package that does that by itself installed on raspian when you start a dist-upgrade.
