osep_scratch切換鏡頭

 記錄一下自已改的地方

src/lib/video/camera.js

在const requestStack = [];後面加上

/*add by chen 20221209 end */

在const requestVideoStream = videoDesc => {
    let streamPromise;
後面加上

let video_value ={};
    const webcamId= `${window.now_webcamId}`;
    if (webcamId == "user"){
        video_value = {facingMode: "user"};
    } else if ( webcamId == "environment" ){
        video_value = {facingMode: "environment"};
    } else{
      video_value = {deviceId: webcamId };
    }

修改video: videoDesc為

video: video_value,
        // video: videoDesc ,video:{facingMode: "user"}, {facingMode: "environment"},video:{deviceId: "xxxx" }
