Media对象不响应包含对象的cookie [英] Media object doesn't respond to cookie containing object

问题描述

很抱歉，如果问题非常愚蠢
我试图使用js显示从一个人到另一个用户的流

Sorry if the question is very stupid I am trying to show the stream from a person to another user using js

我试过把它放入一个cookie但它即使在那时也不起作用。即使视频中的对象与另一个相同

I have tried putting it in a cookie but it doesnt work even then.Even when the object in video is the same as the other

文件1

var video = document.querySelector("#videoElement");
var x=document.cookie
console.log(x)
video.srcObject = x;

文件2

var video = document.querySelector("#videoElement");

if (navigator.mediaDevices.getUserMedia) {
  navigator.mediaDevices.getUserMedia({ video: true })
    .then(function (stream) {
      video.srcObject = stream;
      document.cookie=video.srcObject 
      console.log(stream,video.srcObject)
    })
    .catch(function (err0r) {
      console.log("Something went wrong!");
    });
console.log(stream,video.srcObject)
}

我会喜欢现在只在两个页面上显示它，但是对于将来我应该使用什么语言存储视频，如果你知道你可以分享它

I would like to just for now show it on two pages but for future what language should i use to store the video if you know you can share it

推荐答案

Cookie不是网络上的集中式通用相机访问存储库。谢天谢地。

A cookie is not a centralized universal camera access repository on the web. Thank goodness.

A MediaStream 是表示活动相机使用的本地资源对象，而不是可共享网址。

A MediaStream is a local resource object representing active camera use, not a shareable URL.

此对象仅存在于您当地JS页面，并且无法在网络上寻址。

This object lives solely in your local JS page, and isn't addressable on the web.

由于它不在任何服务器上运行，将图形位从相机传输到朋友的系统，需要相当多的举重。这包括建立 RTCPeerConnection ，它是 WebRTC ：

Since it doesn't live on any server, transporting the graphical bits from your camera to a friend's system, requires quite a bit of heavy lifting. This includes establishing an RTCPeerConnection which is the domain of WebRTC:

navigator.mediaDevices.getUserMedia({ video: true })
  .then(function (stream) {
    const iceServers = [{urls: "stun:stun.l.google.com:19302"}];
    const pc = new RTCPeerConnection({iceServers});

    for (const track of stream.getTracks())
      pc.addTrack(track, stream);

    /* lots of other WebRTC negotiation code */

您通常还需要某种服务器，两者都要解决发现，即联系人，以及一个Web套接字服务器，用于交换必要的批准要约/回答会话描述连接建立，在两个对等体之间。

You'll also typically need a server of some kind, both to solve discovery, i.e. point of contact, as well as a web socket server to exchange critcal offer/answer session descriptions that are necessary for connection establishment, between the two peers.

也许最简单的概念证明是这个cut'n'paste演示，它让您和朋友手动交换所需的WebRTC提供/回答会话描述，让您在没有任何服务器的情况下建立连接，以便彼此查看和交谈。

Perhaps the simplest proof of concept is this cut'n'paste demo, which let you and a friend exchange the required WebRTC offer/answer session descriptions manually, letting you establish a connection without any server, to see and talk to each other.

这有关于有70％的工作机会。如果你们都支持对称NAT（大多数移动网络），那么它会变得更难（你需要一台TURN服务器，需要花钱）。

That has about a 70% chance of working. If you're both behind symmetric NATs (most mobile networks), then it gets harder still (you'll need a TURN server, which costs money).
