【问题描述】：
我正在研究 WebRTC 示例以将视频从客户端流式传输到服务器 https://webrtc.github.io/samples/
我在 Ratchet 中有一个文本聊天，工作正常，现在我需要实现一个视频流到网络套接字，有人可以帮忙吗？
index.php 聊天页面：
<body>
<div id="app" class="container">
<h3 class="text-center">Chat simples utilizando Websocket, Vue.JS e PHP</h3>
<div id="messages">
<div class="col s12">
<ul class="list-unstyled" v-cloak>
<li v-for="message in messages">
<span class="date" v-if="message.date">[{{ message.date }}]</span>
<span class="name" v-if="message.user">{{ message.user }}:</span>
<span class="text" :style="{ color: message.color }">
{{ message.text }}
</span>
</li>
</ul>
</div>
</div>
<div class="row">
<div class="col-12 col-sm-3">
<input type="text" class="form-control" placeholder="Usuário" v-model="user">
</div>
<div class="col-12 col-sm-9">
<input type="text" class="form-control" placeholder="Mensagem" v-model="text"
@keyup.enter="sendMessage">
</div>
</div>
</div>
<!-- webrtc need to stream this -->
<div id="container">
<h1><a href="//webrtc.github.io/samples/" title="WebRTC samples homepage">WebRTC samples</a>
<span>getUserMedia</span></h1>
<video id="gum-local" autoplay playsinline></video>
<button id="showVideo">Open camera</button>
<div id="errorMsg"></div>
<p class="warning"><strong>Warning:</strong> if you're not using headphones, pressing play will cause feedback.</p>

chat.js VUE JS 聊天
var app = new Vue({
el: "#app",
data: {
user: 'user',
text: null,
messages: [],
ws: null,
},
created: function() {
this.connect();
},
methods: {
connect: function(onOpen) {
var self = this;
self.ws = new WebSocket('ws://localhost:8080');
self.ws.onopen = function() {
self.addSuccessNotification('Conectado');
if (onOpen) {
onOpen();
}
};
self.ws.onerror = function() {
self.addErrorNotification('Não foi possível conectar-se ao servidor');
};
self.ws.onmessage = function(e) {
self.addMessage(JSON.parse(e.data));
};
},
addMessage: function(data) {
this.messages.push(data);
this.scrollDown();
},
addSuccessNotification: function(text) {
this.addMessage({color: 'green', text: text});
},
addErrorNotification: function(text) {
this.addMessage({color: 'red', text: text});
},
sendMessage: function() {
var self = this;
if (!self.text || !self.user) {
return;
}
if (self.ws.readyState !== self.ws.OPEN) {
self.addErrorNotification('Problemas na conexão. Tentando reconectar...');
self.connect(function() {
self.sendMessage();
});
return;
}
self.ws.send(JSON.stringify({
user: self.user,
text: self.text,
}));
self.text = null;
},
scrollDown: function() {
var container = this.$el.querySelector('#messages');
container.scrollTop = container.scrollHeight;
},
}
});
server.php 带有 Ratchet 的 Websocket 服务器：
<?php
use Ratchet\Http\HttpServer;
use Ratchet\Server\IoServer;
use Ratchet\WebSocket\WsServer;
require 'vendor/autoload.php';
require 'class/SimpleChat.php';
$server = IoServer::factory(
new HttpServer(
new WsServer(
new SimpleChat()
)
),
8080
);
$server->run();
如果有人有一个简单的解决方案，它可以用 php 或任何其他方法制作，而不是真正与我的文本聊天代码并排，但我更喜欢在上面使用 Ratchet 而不是 node js。提前谢谢各位！

有实际问题吗？ “我想做 X，有人可以帮忙吗”有点含糊。

我需要通过 websockets 流式传输视频，文本聊天部分工作正常
