For #linuxmobile / #postmarketos / #mobian etc. folks: there's a rather beginner friendly task to improve battery life for qcom devices like the #oneplus6, #pixel3a etc. by making sure sensors are idle when not needed.
If you have some spare cycles, motivation, basic C literacy (or want to learn it) and know how to build and deploy/test a package with pmbootstrap (or want to learn it) - this one could be for you.
The details are here: gitlab.postmarketos.org/postma

Only reason it hasn't been done by others already seems to be just lack of time - so let's try to share work among more shoulders, especially as it's a task that's likely going to be quite rewarding :)

I'm very happy about #gnomeshell / #gnome47 shipping HW encoding for its internal screen recorder. With the upcoming #gstreamer 1.24.6 release all currently known bugs are fixed, even though I kinda expect more to come on some multi-GPU setups.
It's about time that we use hw-enc in more places by default and the screen recorder is IMO in a pretty good spot to role things out: on one hand it's used by many people, ensuring we get bug reports, while OTOH its functionality is not crucial.

If things are broken for some users they have lots of alternatives to switch to.

In #gnome47 we'll limit things to H264 on (semi-recent) Intel and AMD (those using VA-API). In the future we'll hopefully be able to extend things to AV1, maybe VP9, and more platforms. Depending on how things develop that'll be V4L2 or Vulkan.

@rmader @nekohayo this is the thing Aral was complaining about, right? funny how it happened without any help/input from him whatsoever

Thanks to @slomo the #gstreamer gtk4-paintable-sink just got support for video rotations. This is nice for video apps, making playback of video recorded on phones (portrait mode) more easy or faster (avoiding a copy compared to using a dedicated gst videoflip element).

The change is even better for Snapshot, the #gnome camera app: it uses the sink for its viewfinder and avoiding additional copies here has quite an impact on #mobilelinux devices.

In the future #gtk4 will hopefully be able to offload the rotation further to #wayland compositors, possibly allowing a zero-copy pipeline from the camera to the display. That needs more work though.

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:

#gstreamer #gtk #postmarketos #linuxmobile #mobilelinux

Similarly the #pinephonepro, which has a proper ISP.

These devices are really on the low-end performance wise - so if things run okay-ish here we should be good with all more powerful devices coming up.

@rmader This is amazing. I can't wait to use the same camera app on my phone as on my desktop.

#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.
