结束与Amazon Chime SDK的会议后如何关闭摄像头

如何解决结束与Amazon Chime SDK的会议后如何关闭摄像头

我有一个使用aws-chime-sdk-js的视频会议网站，并且有一个按钮可以停止当前会议。问题是，即使遵循以下概述的这些功能调用，我也无法使网络摄像头停止将其自身显示为录制内容（指示灯和红色图标）：

https://aws.github.io/amazon-chime-sdk-js/modules/faqs.html#after-leaving-a-meeting-the-camera-led-is-still-on-indicating-that-the-camera-has-not-been-released-what-could-be-wrong

const stop = async (meetingId) => {
try {
    const response = await API.post("chime","/chime/end",{
    body: { meetingId },});

    console.log(response);
    // Select no video device (releases any prevIoUsly selected device)
    meetingSession.audioVideo.chooseVideoInputDevice(null);

    // Stop local video tile (stops sharing the video tile in the meeting)
    meetingSession.audioVideo.stopLocalVideoTile();

    meetingSession.audioVideo.stop();
} catch (e) {
    console.log(e);
}
};

我什至尝试使用getUserMedia分别发布曲目，但无济于事。有什么想法如何关闭摄像头吗？
