Logitech 860 Camera
Beatrix Gerke
I use a Logitech c922 camera with the LogiTune software to crop the camera to focus only on a part of my home office background. However, every time Zoom grabs camera access (including starting a meeting, turning the camera on and off, or even going into video preferences), it treats it as if I am using the default camera settings, ignoring the LogiTune setup.
I can restore the settings by going back to the LogiTune setup process (at which point Zoom recognizes the settings I put in beforehand), but I don't want to be showing my full background for the first 10-15 seconds of each meeting I have.
This is also *only* a Zoom problem -- all other applications that use the camera accept the LogiTune settings without issue. This is also an issue with alternate Logitech software (G Hub) that again works with all other programs.
This issue might be related to another unsolved problem with Logitech cameras not working in HD on new Macs ( -else-having-problem-with-Logitech-webcam-with-the-new/m-p...) since the solutions seem to be similar.
Looks like it worked the test will be tomorrow when things start fresh on my laptop. Having this issue on ONE laptop, not the other, despite them be identical machines and builds. So, I must have a setting different in zoom hoping this is it. Very frustrating.
I have an HD 1080p Logitech camera that doesn't want to work with my MacBook Air (running Monterey). After trying everything, I thought the camera was broken, so I bought a new one. Still didn't work. I then restarted my computer, launched Zoom to test it, and suddenly the camera worked, but the moment I unplugged the camera and replugged it in, it stopped working again. I have now tried this several times, and each time it's the same. I can restart my computer with the camera plugged in, and it seems to work as long as I never unplug it. But the moment I need to unplug the camera, it stops working again unless I restart my computer. Does anyone have any idea what could be going on here?
As a case in point, the Logitech Brio 4K Ultra HD. This camera seems to be advertised to allow adjustments of those properties that I just mentioned above, and I am wondering whether controlling them is accessible via any standard linux command-line (or standard programming API).
Motivation note: I could use these features for acquiring indoors imagery for a machine learning project and the ability to adjust those properties could be important. That aside, these abilities might bear on how much all the sophistication built into this device actually leverages for quality in more mundane use cases like video chat.
According to , one should consult the supported devices list in , the main vehicle for webcam customization in Ubuntu. The model I have mentioned in this question isn't (currently) there, but many other Logitech models are.
Here's one account of the compatibility of the Logitech Brio too (see the Q&A in the comments trail there). Looks like most of the above is adjustable from Ubuntu to judge by that, although I have not tried myself.
I believe however that fps and resolution are selected by the application using the camera (maybe on the video acquisition API / protocol used by each application) and likely not set as a global configuration for the device. If that's not the case please do post a correction comment!
In general, fiddling camera settings is enabled via the v4l2 CLI, which you can use to inquire and change the camera's settings even while it is in use. See for example here. Here's my output from v4l2-ctl -l for this camera:
I can confirm that zoom, auto-focus (on/off) and focus can be set via this utility, but other properties may require using a lower-level utility from the v4l2 suite, or are not supported by this model.
Given that this is a relatively recent Webcam, with USB 2.0 and designed to "plug in" to a standard PC, I'd say "Yes, it will work". I've got a Logitech C920 and an older Microsoft webcam plugged into my PC, and LabVIEW works fine with both of them.
You mentioned IMAQ -- did you mean IMAQdx? I'm pretty sure that you want the IMAQdx drivers. When I plug my Webcam into my PC and open MAX, they show up, and I can do a "Snap" (picture) or "Grab" (video) from the camera. I can also fire up LabVIEW's Vision functions and try to programmatically acquire images, but (of course) this requires the Vision Acquisition Software.
I too have an pre-Logitech c920 webcam, actually the 9000 series. The 9000 webcam (as well as the computer's camera) is listed under devices with both Labview's Vision Acquisition and MAX, but no devices are found with Vision Assistant. Do you have any thoughts as to why Vision Assistant is unable to find the webcams?
Please post and let us know if any of these suggestions helped. The screen shot, above, shows what comes up when I open my Logitech Camera in MAX (LabVIEW 2016). Note the Video Mode and the size of the Region of Interest, which shows the Full Screen size (as it happens).
I recently got a new laptop (Surface Studio Laptop) and my Logitech C930e webcam won't work properly on it.
When it's plugged in, it slows down all apps that use video.
I've tried it in the Windows Camera app, Skype, MS Teams and the Logitech LogiTune app, and in all cases it takes well over 20 seconds for video image to appear, and while they wait, the apps are almost non-responsive.
And not just for the Logitech cam, but also when switching to the built-in webcam.
The moment I unplug the Logitech cam, all these apps respond blazingly fast again, and display the video image from the built-in camera instantly.
When I plug the Logitech cam in again, it immediately slows down apps that use video again..
It sounds like a driver problem, but I can't find it.
It's a fresh installation (reset Windows after receiving the laptop).
I've installed all Windows updates (Windows 10), downloaded the latest version of the Logitech LogiTune app, removed and reinstalled the Logitech cam from Device Management.
I've tested it with various connectors/ USB-C adapters and MS Surface Dock 2.
Long version:I ran across your question after experiencing the exact same symptoms: new work laptop (Dell XPS model 9310) connected to a KVM with a Logitech C930E that runs fine on the other computer, a desktop. Camera super slow when initializing via Teams or the Camera app. More annoying, I found Windows Settings would seize when selecting "System/Sounds" or right-clicking the speaker in the system tray and clicking "Open sound settings".
I gradually narrowed down the problem to the C930E by connecting it directly to the laptop with nothing else and getting the same slow start and broken Sound settings. Because it was related to sound, I figured I'd try to isolate the problem by disabling other sound devices. A bunch of trial and error yielded "Intel Smart Sound Technology for USB Audio" as the culprit.
The driver for that (as of this comment) is version 10.29.0.6040 dated July-07-2021. I thought Intel might have a newer one than Windows Update, so I set up their Driver & Support Assistant, but it's the same driver, so I suspect that 6040 is indeed the newest driver and it just does not like the C930E for some reason.
I also had the same issue with a C930e. The benefit that I had was that I had 2 of them and the computer was a laptop that was brought back and forth between home and work offices. Brought the camera from the home office to the office and replaced the "slow" one and it worked perfectly again. The best way I can describe the situation is that the camera seemingly wore out. I know that sounds silly, but it was so slow to respond to commands from the OS/Apps in getting either the microphone or the camera enabled and working at the start of calls.
I had the same issue with Logitech C930e, with a the system hanging on zoom calls. After some investigation i also narrowed it down to the audio/mic, and after googling for quite some time the solution of disabling the "Intel Smart Sound Technology for USB Audio" also solved it. Some users also got it fixed by updating their audio driver where the intel driver is loaded so that can also be an approach.
I've attached a USB camera to the Pi Zero W running PrusaLink, but I don't see any interface to activate it. When I go to the connect.prusa3d.com on the Camera tab (on another computer), it prompts me to add that computer's webcam. I'd rather use the camera physically attached to the printer.
Hi, I guess you might be on an old version? If you are on the 0.6.1 - please flash the 0.7.0 available here: -Link/releases/tag/0.7.0
If not, you might want to enable ssh and see if you can see the camera in the output of lsusb
OK, awesome! I made some progress. Installed 0.7.0 and I now have the camera connection interface in PrusaLink (connected locally, trying to get that set up first then I'll wrassle with PrusaConnect).
However, all I get is a window with a thumbnail of a (?) icon in the middle - no image from the camera. I'm quite dense about Linux (especially multimedia Linux). Can I telnet to this thing and poke it and make it do stuff?
What part number does your camera have? Ours has 860-000441 and works almost perfectly. Sometimes a frame is garbled at the end, but it at least sends them.
I would like to get my hands on one that just does not work like yours.
I might have deduced wrong tho.
Anyway, the reason I asked for the part number is because there might have been a HW revision and we might have two different cameras even tho they are labeled the same.
We have to have two different cameras in some way. Because one appears to be working. Or, there's an issue with the prusalink install somewhere
I have a brand spankin' new right out of the box Logitech C270 part number 860-000441. I ran the software installer listed above, and no change to the behavior in PrusaLink. I'm not convinced that the software installer actually did anything to the camera firmware. I'm going to investigate some more, and try the Windows version to see if that makes a difference.
