From 0ce8f2390b5280887a2ac179faf2aa01604cb1cc Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Fri, 6 Dec 2019 04:14:52 -0500 Subject: v4l2: v4l2_compat: Add V4L2 compatibility layer Add libcamera V4L2 compatibility layer. This initial implementation supports the minimal set of V4L2 operations, which allows getting, setting, and enumerating formats, and streaming frames from a video device. Some data about the wrapped V4L2 video device are hardcoded. Add a build option named 'v4l2' and adjust the build system to selectively compile the V4L2 compatibility layer. For now we match the V4L2 device node to a libcamera camera based on a devnum that a pipeline handler may optionally map to a libcamera camera.
