Camera not working on Dell XPS 13 9370
Hi,
Installed eOS 6.0 The camera worked without any issues on eOS 5.1.x. Seems not to be working now. Installed Cheese and that works fine but it would be nice to have the default camera app working. I just get a black "image" in Camera and the camera light doesn't come on so it seems like it isn't even recognising the hardware.
Output from lshw: *-usb:0 description: Video product: Integrated_Webcam_HD vendor: CN0FFMHCLOG0087TB1W8A01 physical id: 5 bus info: usb@1:5 version: 72.79 serial: 200901010001 capabilities: usb-2.01 configuration: driver=uvcvideo maxpower=500mA speed=480Mbit/s
Thanks!

The webcam works fine with Cheese, ffplay and howdy.

Do you have two cameras installed? There is a possibility of an issue related to two cameras.
I have only one camera but it actually has two: RGB + IR

Hope this helps. Thanks.
@casasfernando Thanks! If it is an integrated device it could be giving the same display name for both video0 and video devices, in which case PR #190 may fix you issue. If you are able to test that PR and leave a comment that would be great.
@im-barney @casasfernando @bmbariah can you confirm whether the camera light comes on and a photo is taken when you hit the capture button? I'm seeing something similar here and wondering if it's the same issue or not.
I just checked with the latest version of Camera (system up to date) and things improved a little bit.
- When I first open the app I now get to see an image (previously it was just black) and the camera light is on.
- I see two cameras listed in the app, both with exactly the same name. Only the second one in the list works (shows image and the camera light is on).
Now to answer your question @cassidyjames if I click on the capture button the image just freeze, but no picture is taken/saved and the camera light goes off (the image in the app is still there tough). The only way I found to get it back to work is to select again the second camera from the list. Then picture is live again and camera light is on.
On the other hand if I switch the app into video capture mode and I click on the capture button the camera light remains on, the image is still live -but with many random freezes- and when I click on stop, the video is saved correctly but the image freeze, the camera light remains on and I need to select again the second camera from the list to get it to work again. If I playback the saved video, it looks exactly as while capturing it, with a lot of freezes and no audio during the freezes.
Camera version:
Name Application ID Version Branch Origin Installation
Camera io.elementary.camera 6.0.2 stable appcenter system
Hope this detailed description of the current status helps. :smile:
Thank you @casasfernando! It sounds like it's not the exact issue I am seeing in #198 then, so I will leave that issue open.
In case it helps I just ran Camera in debug mode and this is the output when trying to capture a photo:
