Giving Linux a Camera Stack: libcamera's 3 Years Journey and Exciting Future
summary
libcamera is a complete user‑space camera stack that turns raw sensors and SoC ISPs into multi‑stream, hot‑pluggable Linux cameras by combining kernel media controller drivers with device‑specific pipeline handlers and sandboxed IPA modules for image algorithms. development used VM C testing, IPU3 and RK3399 targets, and a Raspberry Pi partnership (May 2020) that produced the first open ISP algorithms; features include v4l2 emulation, Android HAL and GStreamer integration, LGPL pipeline code, and per‑frame controls.
