如何通过videojs-record将正面摄像头切换为背面摄像头进行图像采集？

Question

这适用于视频(代码片段摄像头更改为背面摄像头)

 videoPlayer.record().stopDevice();
 videoPlayer.record().setVideoInput('backface-camera-device-id');

但以此类推，图像不会改变任何事情。摄像头仍然相同(仅正面摄像头)

 imagePlayer.record().stopDevice();
 imagePlayer.record().setVideoInput('backface-camera-device-id');

我对imagePlayer的选择是

const options = {
                controls: true,
                width: width,
                height: height,
                controlBar: {
                    volumePanel: true
                },
                plugins: {
                    record: {
                        image: true,
                        imageOutputType: 'blob',
                        mandatory: {
                            minWidth: 1280,
                            minHeight: 720,
                        },
                        frameWidth: 1280,
                        frameHeight: 720,
                    }
                }
            };
const imagePlayer = videojs('image-frame', options);

图像帧是

<video id="image-frame"></video>

我的视频选项(仅适用于视频)

const options = {
                controls: true,
                width: width,
                height: height,
                fluid: false,
                controlBar: {
                    volumePanel: false,
                    cameraButton: true,
                },
                plugins: {
                    record: {
                        audio: true,
                        video: true,
                        videoEngine: 'recordrtc',
                        maxLength: 120,
                        debug: true,
                        mandatory: {
                            minWidth: 1280,
                            minHeight: 720,
                        },
                        frameWidth: 1280,
                        frameHeight: 720,
                        timeSlice: 1000
                    }
                }
            };

很高兴有任何帮助或线索来解决相机切换问题！

Answer 1

imagePlayer.record().recordImage = {deviceId: {exact: 'backface-camera-device-id'}};
imagePlayer.record().stopDevice();
imagePlayer.record().getDevice();

对我很管用。
