#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.

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 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.

Note that with all of this in place, camera support on a lot of other devices is in close reach. For example the and should only need kernel patches enabling the camera sensors. The softwareISP should then - at least in theory - "just work". Well, fingers crossed :)

P.S.: the one device where this already worked is the - but until recently it broke audio. That was also fixed in the process.

Turns out that there were still two things missing to make this work OOTB. One thing was a missing package - already fixed - and the other will be fixed in Wireplumber 0.5.3, due in a couple of days.

@martijnbraam Do I understand correctly that you are using Gstreamer for encoding? In that case it might be worth checking out https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5676 which implements HW encoding. Getting that over the line could be a big deal here - and for other apps like Snapshot or Dino as well.

@martijnbraam Also the librem5 if I'm not mistaken. I also hope it will just be compatible with cedrus though - the h264 decoder seem to work somewhat well here, even though we'll need to support more tiling modes / drm modifiers in Gst to make it really fast.
Don't know about the kernel side of the encoder though - do you know if it generally works?

If you want to follow the process of getting the (with softwareISP) + stack into place on - which will allow way more apps to use cameras on devices like the , (the was the first were it already kinda works) and hopefully many more devices in the future - then here's a meta issue you can subscribe to: https://gitlab.com/postmarketOS/pmaports/-/issues/2787
