Camera support progress
#1
Hello,

A few interesting patches by megi have made their way to the pine64 kernel lately, bringing improved drivers for the pinephone cameras.
With a couple of extra hacks on top of that, and an experimental build of gnome-camera, support for the back camera should be working "out of the box" with the next nightly build Smile

This is far from perfect, and should be regarded as some kind of "technology preview": image resolution is 720p only, and the quality is really poor atm.
Still, I believe this is a major step forward!

You can test by first upgrading your system, then running the following command:
Code:
sudo apt install gnome-camera
(a reboot is required)

Enjoy!

Hello,



Great news if camera support is making progress !


I've wanted to eagerly give it a try, updated the packages to the latest version, installed gnome-camera and rebooted,

but it doesn't seem to be working on my device (mobian-pinephone-20200704 flashed to the eMMC and updated several times since):   

I'm getting a black viewfinder and clicking the capture button doesn't seem to record any image (Should they be stored in Pictures ?).
I've noticed that during app launch, there are a couple of clicking noises (if it might help).



Thanks for the great work on Mobian !

Camrea app is there , but when started the camera doesn't work
I see the app + round trigger button + but screen is black ... aka. no camera pixels seen.

Right, this should be fixed now, an new update+reboot cycle should get you there Smile
Sorry about the mess...

It's working as of right now. Initially there was no video shown and had the same output posted above.

Anyhow laggy, but works.

Edit: Awesome work, so far Mobian has been the experience I was looking for. Thanks.
