Why Embedded Cameras are Difficult, and How to Make Them Easy
summary
A new open camera stack called libcamera provides a C++ library with a C API, device enumeration, per-frame controls, multiple simultaneous video streams and high‑level profiles (for video conferencing, still capture, etc.) and adapts to V4L2 and Android Camera HAL. Vendor pipeline handlers are open source while performance‑critical 3A image algorithms run as sandboxed 3A over IPC using dma‑buf to avoid copies. Code and mailing lists are public on the Linux TV hosting for contributions and testing.
