Tested the latest #GNOME #Snapshot on #postmarketOS on my #PINE64 #PinePhonePro! It's been a while since I revisited the PinePhonePro but with cameras and camera utilities coming a long way on newer devices I wanted to revisit #libcamera on the PinePhones. I installed @NekoCWD's cameractrl and it successfully controls focus, but the PPP camera seems to have autoexposure that reduces the utility of cameractrl's exposure slider. Anyways, here's a picture of some other postmarketOS devices.

@CalcProgrammer1 @NekoCWD nice to know the slider works for focus! Now we don’t have a hard requirement on the AF algo for libcamera.

@Luigi311 @CalcProgrammer1 @NekoCWD You ... really need AF algorithm, sorry. Manual focus on phone screen with no hints... just does not work well. Feel free to take a look at megapixels, AF is somehow working in there. And you don't even need to do it in libcamera, you can do it in application, too, even if that is wrong place.

@pavel @Luigi311 @NekoCWD It's definitely not the greatest, but at least focus is functional. I think it's up to libcamera to implement a generic software AF algorithm and maybe for Snapshot to implement enabling it. Megapixels doesn't seem to work with anything except the original PinePhone in my testing so that's not a viable option yet.

@Luigi311 @CalcProgrammer1 @NekoCWD Should there be mailing list for phone camera development? Or use phone-devel@vger.kernel.org?

@CalcProgrammer1 @Luigi311 @NekoCWD Megapixels work on Librem 5 and PinePhone Pro, too, at least. Compared to libcamera, it is quite easy to hack.

libcamera does not build on my Librem 5 due to meson requirements, but I'm currently playing in that area (libobscura + unicsy camera, close enough), and might want to help.

Should there be mailing list for this?

@pavel @CalcProgrammer1 @NekoCWD Yes thats true that the algorithm really does need to exist i just meant more of you can atleast use a single app now with the manual focus adjustment in the mean time and not get a blurry mess to test libcamera.

Megapixels indeed has AF and does work on the PPP as long as you are using megapixels 2 or the dowstream fork of the first one.

AF at the application level though isnt all that useful since that wont give you AF in firefox or say xmpp clients.

@pavel @CalcProgrammer1 @NekoCWD as far as i know there no overarching mobile camera related mailing list. Theres the individual libcamera mailing list and the matrix room for megapixels and one for libcamera but thats about it as far as i know. I dont really use mailing lists but im subscribed to the libcamera one atleast.
