Logitech Webcam Hd 1080p
Steven
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.
My webcam ends up in a weird audio loop which is broadcast to everyone. Even if I log out of Teams or Zoom it continues. It didnt happen before I upgraded to Monterey. rebooting the Mac fixes it. Also unplugging the USB-C and reconnecting it fixes it. Any ideas, its very annoying to users on the other end?
James, the issue isn't the mic picking up speaker noise or that type of feedback. It will take some noise (perhaps what I said, or what someone on a video call said) and just repeat it over and over. If I mute the USB mic, it goes away, and if I use the Mac onboard Mic, it goes away. as soon as I unmute the USB camera/mic, it starts to repeat that same noise over and over.
running sudo killaudioa, or rebooting, or unplugging the USB item seems to fix it. I've used different docks and different USB camera (same model but physically a different one) and it does it. Not all the time, but when it starts the loop of repeating, the only things that fixes it is to restart, run the sudo or unplug/plugin the USB. Something with the MAC that is causing it.
I'm also having this problem--my audio in Teams will randomly start repeating a small clip of what I or someone else says on an endless loop. It doesn't happen every meeting--and there's no real pattern.
I downloaded Logitune software (wasn't easily found or listed on Logitech's site) and through that, I updated the firmware on both home and office cameras. I've not had the issue since (5-6 weeks ago), so it appears it resolved my issue.
This was acknowledged by Logitech support. Whether there will be a fix isn't known. I'd say it depends on how deeply the issue is buried in the differences between the USB A and USB C ports on the Mac's hardware or firmware
Audio looping is typically caused by the audio coming out of the speakers, getting picked up by a microphone and fed back into an audio / video conference where there is a slight delay. We used to have physical conference rooms that were connected to the meeting with microphones on the table or in the ceiling and speakers. If someone joined the conference with their laptop and were present in the conference room we would get the audio looping problem. As the laptop microphone would pickup the audio from the rooms speakers and pipe it back into the audio conference where it would play back on a slight delay and then the playback looped through the microphone again, etc. etc, etc.
That is because the audio leaving the speakers, enters the microphone. See this with many systems, not just Mac's. On most video conferencing systems such as Zoom, WebEx, Teams, etc. there will be a delay and full loop. On other systems where there is far less delay you will have more of an echo effect.
It seems that Mac's with built-in speakers and microphones are avoiding the problem but external speakers and microphones are a problem. Otherwise it's a second device in the room joined to the same meeting and that device is picking up the speaker output on it's microphone and causing the looping.
I actually had the speakers muted and it would still do it. I think I've chased it down to an issue with the Logitech camera (Brio). I've updated the firmware and if that doesn't fix it, I will need to plug it in directly to my Mac versus a dock.
Same Problem with Logich brio and stream cam. Both worked well on old Intel Mac (or Windows Laptop). With new M1 Mac mini or m1 Laptop and Same external speaker and cams i run Into the Same problem as described above. Nothing helped so far.
Mine was at all times connected USB C to USB C and the loop was there. After speaking to Logitech support, they informed my that my Brio was faulty and had to be replaced by the retailer which happened. The new Brio was connected, firmware update - problem the same :-(
My setup was working perfectly on an Intel MacBook Pro. The software config on the Mac Studio is virtually identical and I'm finding peripheral connection on the new hardware to be downright flakey (my Logitech mouse goes haywire when waking from sleep). There's obviously some fundamental hardware, firmware or software differences that are creating problems. I personally hope is in the ARM version of Monterey is the issue as that should be relatively easy to fix. Flashing new firmware onto one of these M1 machines looks like a right pain in the butt
For a double-check, I also tried it on a separate iMac - in MS Teams I used the Logi camera and the iMac inbuilt microphone. Again no problem. So it appears to be something to do with the Logi microphone. Using a completely separate USB microphone results in no problems. An added bit of expense, but solves the issue.
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).
Finally, I tried reverting to Pulseaudio. From reading on the forums, it seems this is something that has fixed a lot of problems for a lot of people, at least up to Fedora 35. However, it comprehensively FUBAR-ed sound for pretty much everything else on my system, so I reverted back to Pipewire.
Hi Elliott. I unplugged the webcam from the USB 3.1 port at the back of my PC (which goes straight in to the motherboard). I have a second USB 3.1 port on a front-mounted panel on the PC - I plugged the webcam into that, and it worked!
I am glad that worked. I was worried that the drivers were not "blessed" by microsoft. I have a Casio Title Printer that basically prints names on a CD/DVD and I cannot use it when Windows core protection is enabled. I have to disable memory integrity or the driver will not load.
Hello, I have been having the same problem with my c925e after updating to Windows 11. I've tried installing the LogiTune software, factory resetting the webcam, updating drivers through the control panel, and resetting my computer many times. I have seen that this particular webcam may not work with my Windows 11 type. If you could help me out with this situation it would be greatly appreciated.
I can connect with the webcam using "rosrun usb_cam usb_cam_node" but when I want to see the visualizer using "rosrun image_view image_view image:=/usb_cam/image_raw", I only see a green image from the webcam. Also, I tried to visualizing the webcam images with rqt_image_view and I can see the same.
I returned all 3 of them and ordered the C930e from Walmart. These came labeled as C930e, but when I plugged the first one into a laptop, it installed the drivers like you would expect, but one of the new devices was a SCSI device with Chinese characters in the description. The laptop automatically rebooted to finish installing the drivers. The laptop never booted again. The boot partition was scrambled and I ended up wiping the laptop with a clean install of Windows 10. After the clean install, I setup the laptop on an untrused network and attached the camera. There are 4 different devices that appear in the device manager with Chinese charaters in the name. It looks like they sent me C930c even though the box says C930e.
