BoF: Cameras on Linux
summary
Linux camera stacks are now centered on libcamera and the Media Controller graph, with concrete features: libcamera 0.5.1 exposes pipeline handlers, a V4L2-compat adapter for legacy apps, and a GStreamer plug‑in that uses GStreamer 1.26 format modifiers. Kernel 6.12–6.15 adds many ISP drivers. The talk demonstrates mem‑to‑mem pipelines, the VimC virtual media controller for testing, a media controller multicontext RFC for time‑multiplexed ISPs, a CPU software ISP (GPU ports planned), and CamShark for IPA debugging.
