vflip not working
I have the vertical flip attribute in my config set to true, but in homebridge the camera is not being flipped.  Is there a way to fix this?

        {
            "platform": "Camera-ffmpeg",
            "cameras": [
                {
                    "name": "PiCamera",
                    "videoConfig": {
                        "source": "-f v4l2 -r 30 -s 1280x720 -i /dev/video0",
                        "maxStreams": 2,
                        "maxWidth": 1280,
                        "audio": false,
                        "maxHeight": 720,
                        "vflip": true,
                        "hflip": true,

                        "mapaudio": "0:1",
                        "debug": false
                    }
                }
            ]
        },
