Libcamera: Making Complex Cameras Easy
summary
An open C++ camera stack claims to map complex media-controller + V4L2 topologies into a single camera object, already capturing frames from UVC and Intel IPU3 and running a native test app; plumbing, hot‑plug camera manager and unit tests against Linux vivid virtual devices are functional. Platform-specific bits live in pipeline handlers, image‑processing (3A) can be proprietary in a sandbox for closed-source ISP algorithms, and legacy apps get compatibility via an LD_PRELOAD V4L2 shim. Project plans a ~one‑year rollout with Raspberry Pi and Rockchip targets.
