javascript – 如何从Blob网址检索MediaStream?

navigator.getUserMedia({ video: true, audio: true }, function (localMediaStream) {
var video = document.querySelector('video');
video.src = window.URL.createObjectURL(localMediaStream);
video.onloadedmetadata = function (e) {
// Do something with the video here.
};
},
function (err) {
console.log("The following error occured: " + err);
}
);
问题是现在我有一个blob URL,如:
blob:http%3A//localhost%3A1560/f43bed15-da6c-4ff1-b73c-5640ed94e8ee
有没有办法从中检索MediaStream对象?

import { DomSanitizer } from '@angular/platform-browser';
constructor(

//your code comes here...
video.src = this.sanitizer.bypassSecurityTrustUrl(window.URL.createObjectURL(stream));
这应该只
