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.
I just made some changes to @libcamera to export focus/brightness controls and created a PoC app to work with it via @pipewire (wireplumber gobject api) in @vala_lang because why not? @postmarketOS
First try to create #libcamera swISP tuning files for the OnePlus6 with #ideasonboard folks at #embeddedworld. Unfortunately we hit an issue that we couldn't fix on-side - got a few todos to make sure things work out next time!
4. Thanks to #libcamera enablement work, udmabuf is available to users by default in many distros now and #systemd 257 sets an uaccess tag. It's not yet available in #flatpak without device=all, though.
5. The main missing DRM formats are three-plane >= 10 bit ones that are compatible with what sw-decoders produce.
6. AFAICS the approach should work equally well for clients like #mpv, #firefox and #chromium.
P.S.: the idea was inspired by the #libcamera sw-ISP and the MR can be found at

Mon 3rd Feb, just a day after the #FOSDEM we'll have small HackDay in Brussels — hopefully making more cameras run well on #Linux, #embedded, #postmarketOS & #Mobian
If you're interested to help with hacking around #LinuxKernel CCS, #libcamera or #Qualcomm CAMSS (not limited to) ping us on #qcom-camss OFTC IRC channel or here.
For #linuxmobile #postmarketos #mobian folks interested in cameras: there's a first version of patches for #libcamera softwareISP color correction matrix (CCM) support now: https://patchwork.libcamera.org/cover/22041/
Together with autofocus (AF) this probably the main missing feature to get a somewhat reasonable image quality on devices like the #pixel3a or #fairphone5 with open drivers / close to #mainlinelinux.
I finally got the official #funding confirmation from @PrototypeFund .
Time to gather the needed contacts before I begin with #libobscura next month!
#libobscura is going to be a proof of concept #linux #camera library which doesn't make the same mistakes as #libcamera . I'll base it on @martijnbraam 's work with #libmegapixels .
I'm quite happy how upcoming performance improvements for #gnome Snapshot and #libcamera are shaping up. This is how things are now running for me on a #librem5:
#firefox #webrtc using #pipewire and #libcamera (with softwareISP) on a #thinkpadx13s - it finally works \o/
The required patches will also make things work for a bunch of #linuxmobile devices.
Don't expect too much for now: both image quality and performance are not quite where we want them to be.
That, however, also means that there are a lot of low hanging fruits where help is very welcome :)
We need to create #libcamera tuning files for the individual cameras, the swISP could be improved to use the GPU for debayering, there are WIP autofocus patches that could be tried and improved - and in Snapshot we need to reduce the number of copies before frames reach the screen or encoders.
#postmarketOS just landed the last MR needed to make the #libcamera + #PipeWire camera stack work on the #Librem5 and #PinePhone by default, using the new software ISP shipped in libcamera 0.3.
So if you have such a device: just update and go install apps like Snapshot, Warp, Decoder etc. You can even use it with Firefox and - very soon - Chromium.
Note that this does *not* replace #megapixels or #millipixels - those continue to be the default camera apps.
Shortish impressions from #linuxday
I've took an early enough train so that I would be able to attend the very interesting talk about #libcamera at 10:00
Of course having arrived at the premises I quickly scouted out the stands, and immediately met with some #Debian friends and noticed a huge, but friendly #linux penguin wearing a #froscon shirt :)
All pictures are *obviously* #ShotOnLibrem5

#Firefox with the #postmarketOS #LinuxMobile patches will now use #PipeWire (and thus #libcamera ) by default, allowing cameras to work out-of-the-box on distros shipping that patchset (well, assuming the camera works with libcamera of course).
https://gitlab.com/postmarketOS/mobile-config-firefox/-/merge_requests/38
Just to clarify: this will work on any device with #libcamera support. Hoping to try this soon on the #Librem5 !
Hacking at #LAS2023: first video call using @dino between two #PinePhonePro s
Using the modern video stack #libcamera #PipeWire
Pretty cool milestone for cameras on the #PinePhonePro and the #libcamera + #PipeWire stack today: the #Manjaro images (the stock distro) for both #phosh and #PlasmaMobile now come with all required packages by default.
Finally I can simply install cheese and get an image.
Yes, the rotation is still wrong. Yes, there are still features missing that you'd expect from a modern camera stack. Yes, there are still bugs and suboptimal image quality. But we got a working base now.
#iLoveFreeSoftwareDay at #cbase - DJ using #mixxx and #PipeWire on #gnome. #ShotOnPinephonePro using #PipeWire and #libcamera. Sound quality is better than the image one :p
