Built-in Webcam Not Working
#1
I received my PBP today, and just trying out all the features, but for some reason I can't get the built-in webcam to work.

I've tried Kamoso and Cheese - cheese outputs this "cheese-application.vala:214: Error during camera setup: No device found"

Under the /dev/ there is /dev/video0, /dev/video1, /dev/video2. Using that, I've tried smplayer /dev/video0 as well as video1 and video2, but nothing shows.

I've also checked that the webcam is enabled (double flash from [Pine]+[F12]).

Can someone help me diagnose this please?

check if your user is added to the video group
dmesg|grep video
if not detected, toggle the privacy hardware disable and reboot
dmesg again

the camera works, but is not great

On my system, the camera is /dev/video3. video0, video1, video2, and video4 are all different handles on the video processing unit, as I understand it, and won't respond correctly when opened under the assumption that they're cameras.

Does yours not have a /dev/video3?

I also received my PBP today too! Have you tried enabling it via the privacy switch?

Yes, my user is added to the video group.

Here is my dmesg output (doesn't change if the privacy switch is enabled or disabled):

$ dmesg|grep video

As you can see - only video 0, 1 and 2 are detected

I tried Manjaro KDE, Debian and Android images, camera did not work in any of those.
I also tried switching the camera off with SUPER + F12, rebooting, switching it back on and rebooting again. Still no luck.

My dmesg | grep video output:

If I try to run smplayer /dev/video1 I'm getting this error:

I also tried Jitsi Meet and Google Hangouts, both in Firefox and Chromium, Kamoso and Cheese, nothing works.

Is there anything else I could do to check if the camera hardware works?

Yes, my user is added to the video group.

Here is my dmesg output (doesn't change if the privacy switch is enabled or disabled):

Actually, your output is different. Notice that you have these lines:

Code:
[    8.693178] uvcvideo: Found UVC 1.00 device USB Camera (0c45:6321)
[    8.729161] uvcvideo 2-1.2:1.0: Entity type for entity Extension 4 was not initialized!

[    8.729182] uvcvideo 2-1.2:1.0: Entity type for entity Camera 1 was not initialized!
[    8.730958] usbcore: registered new interface driver uvcvideo

I'm not getting those, and it looks like fozzedout is not getting those lines either.
