Libcamera 0.7.1 released on Tuesday as the newest feature release for this open-source library for camera image signal processors (ISPs) that has grown of importance for the likes of Raspberry Pi and Chrome OS and modern desktop Linux distributions with modern laptop hardware like recent Intel Core (Ultra) laptops.

The libcamera 0.7.1 release is now making use of C++20 by default as its C++ dialect set with its Meson build system. The new release also revamps its configuration file handling.

Libcamera's software ISP "SoftISP" implementation has been improved with v0.7.1 to now support multi-threaded Debaying. The multi-threaded Debayer aims to provide better performance and especially useful for low-power platforms like the Arduino Uno-Q. Hans de Goede at Qualcomm worked on this multi-threading support and with the Arduino Uno-Q scaled nicely from 6.5 to 12.5 FPS from 1 to 2 threads while at 3 threads hit 15 FPS.

Libcamera 0.7.1 also has improved its RKISP1 IPA and Mali-C55 hardware specific code, including for enabling cmaera support on Renesas RZ/V2H and RZ/V2NP platforms.
