There’s two interesting developments in that regard: libcamera support for software isp/ipa by the libcamera devs (prompted by sensors found in recent laptops):
- [libcamera-devel] [RFC PATCH 0/7] libcamera: introduce Software ISP and Software IPA
and related [libcamera-devel] softISP for libcamera
(which will then make it simpler to use it with pipewire)
and the work on megapixel’s 2.0 Megapixels 2.0 which would make it easier to use it in a library like fashion.
