I was recently experimenting with VLC and somehow it changed my webcam aspect ratio from 16:9 to 4:3, so that when I'm in video chats, I now have bars at the sides of my image. I have been searching, but cannot find any way to change it back. Any idea how to do that? Also what is VLC (or any other app) doing setting the aspect ratio, so that other apps are affected? tnx jk
Forgot to mention, I'm running 15.2 & KDE and have a Logitech C270 camera. On 2020-12-12 2:09 p.m., James Knott wrote:

Other apps should be able to change it to whatever they prefer, too. Possibly you can also use vlc to set it up, too. I'll try. It is on "Capture device". [...] I do not see the controls... I can zoom or change the display, but not what the camera does. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

I have tried VLC to change it. There is a box for aspect ratio, but it's 4:3. I can't change it to 16:9. I also haven't seen an aspect ratio setting in any other app I've tried. I normally use a browser for video chats. For example, my friends are meeting with Jitsi and there's no setting in there for aspect ratio.

I can, but what it does is distort the image.

Try https://meet.opensuse.org I don't see controls. https://test.webrtc.org/ It fails my mike, which is wrong. Try "cheese", but it displays nothing here. Ah, it works, but it takes long to start. I tried fidling with controls, then the camera stopped working, even in o.o.meet. I had to unplug the camera and replug to make it work. And now cheese works again. -- Cheers / Saludos, Carlos E. R.

in order to alter the webcam aspect ratio, I would guess it would be necessary to alter the webcam's configuration as it delivers what it delivers in spite of what one opts to display. vlc merely displays what the webcam delivers. changing aspect ratio via vlc would skew the image.

I use Guvcview to set up no-name webcam. under Image Controls I set Power Line Frequency to 60 under Video Controls I can set the resolution to 320 240 640 480 800 600 1024 576 1280 720 1920 1080 Maybe one of these will work for you. HTH

I set it to 1280 x 720, which is what the camera is supposed to be. While it accepts the setting, it doesn't fix the problem.

I think you have a typo, it's 1280x720 720/9=80 1280/16=80 16:9 aspect ratio

James Which program did you use to try to make this change? Are you using VLC as you mentioned before? My camera does not have a seperate setting for aspect ratio. Maybe to get some info about what the kernel thinks this camera is all about, check out what dmesg says after pluging it in. #dmesg | tail -n 30 or similar should work. You can also try installing this small cli program uvcdynctrl from Yast. Ask it to show you the frame formats that it is able to provide, #uvcdynctrl -f You can also view basic info for the camera #uvcdyctrl -l Also view the controls that it provides #uvcdynctrl -c We may get some clues we can work with. I had problems setting up my webcam. What a pain. Serafino

I have tried several, including the app from Logitech. This appears to be a camera issue, not Linux, as it also happens when I connect the camera to my notebook computer and boot up Windows 10. The Logitech app has some setting, but no apparent way to commit the changes. VLC has a box for aspect ratio, but it's 4:3 and it doesn't change, even after entering 16:9. There is a webrtc test site, which can change the resolution and I can see 1280 x 720 works fine, but doesn't stick when I use jitsi or other video chat.

When I was at the store buying mine, the sales assistant told me that the person he was serving before me had bought 5 webcams, a few were for spares, he said. When I got mine home and tried it out, it had 2 blue led's one on each side of the lens. After a few minutes I went to adjust the position of the camera and I happened to touch the back surface of the camera. It felt a little too hot. A few minutes later one of the led's stopped working and the back of the camera wasn't as hot any more. What luck. Fortunately the camera still works ok.

This is getting frustrating. I plugged my camera into my ThinkPad and booted Windows 10. The camera is 4:3 there too. I installed the Logitech app for configuring the camera, but there appears to be no way to save the settings!!! WTF??? All because I tried running VLC!!!

Maybe the use of VLC was coincidental, and something was done the video chat engines to automatically choose another resolution/aspect ratio. For example, soon after the start of the confinement here, the fibre video services switched to lower resolution (not 4K) modes during the day, because they were being overloaded with so much usage of people forcing to stay at home and working at home. -- Cheers / Saludos, Carlos E.

Well, it affects Jitsi, Meet, Skype and Zoom, but not on my ThinkPad with it's own camera, but with the Logitech camera on that same ThinkPad. It also happens on both Linux and Windows 10 and with Chromium and Firefox browsers. This would tend to point to something with the camera. I have tried the Logitech app, but even it doesn't save the higher resolution. BTW, I have a 500/20 Internet connection.

My camera is now back to normal. It appears to have been restored after I was on a Teams chat. Also, it is apparently not an uncommon issue: https://community.jitsi.org/t/meet-camera-solution-640-x-480-instead-of-1280...

As I mentioned, I have absolutely no idea why this problem happened. All I know is it happened after I used VLC and cleared after Teams. I linked to that list to show I wasn't the only one to show I had that problem. Whether it was caused by an issue with Jitsi, I really have no idea. It just happened.
