V4l2Camera – Open Source package released

V4l2Camera is an attempt to abstract the video4linux2 api into something more easily usable in a generic C++ application

• I set out, naively, to create cross-platform support (Linux, MacOS, Windows) but soon realized the extent of that effort
• The Linux version is “done”, although I know there are lots of refinements possible/needed/required
• I think I see a path forward on the MacOS and Windows side of things after starting down a few interesting pathways (libuvc, libusb)

Details

• Low level camera control using (or emulating) the video4linux2 interface
• Currently supporting Linux based systems (tested on Debian AMD64 and Raspbian ARM64 platforms)
  • support planned for MacOS (via AVFoundation api), and
  • Windows (via Media.Capture api)
• Designed to support both command line and GUI based applications
• Example code provided for command line application, sample application (binary-only) provided for GUI based application
• Distributed as open-source under the MIT License
