Oops it looks like unrelated to this PR I've broken CI so that the tests are not actually ran 😅 I'll test this locally and fix CI when I have the chance, but overall this looks good. Thanks 🙏 |

With multiple cameras, it can be handy to set the video devices using the symlinks provided in
/dev/v4l/by-idor/dev/v4l/by-path, because the IDs in/dev/video<ID>may change after a reboot. However, the relative paths from these symlinks are currently just appended to /dev/ and thus falsely resolved to/dev/../../video<ID>.With this PR, symlinks located in another directory than /dev/ can be used for the video_device parameter.
