Todo

  • Check open issues and pull requests and see what can be done.
  • Add tests.
  • Add output examples from additional camera models.
    • Perhaps create and record a demo video/gif for that model.
  • Add workarounds for cameras with known issues.
    • Some cameras are known to have issues in other implementations.
    • Avoid camera- or system-specific workarounds, try to be generic in their detection and prevention.
    • See Linux UVC device drivers’s supported devices list for examples.
  • Compare UVC controls/values with the output from v4l2-ctl.
