如何将video(从getUserMedia)发送到Node.js服务器?

我正在build立一个聊天/直播应用程序(video+文字聊天)。 目前我还没有解决办法,但是我正在向前迈进,而且我陷入困境。

我正在尝试使用getUserMedia获取videostream,并通过Socket.io将其发送到我的Node.js服务器。

到目前为止,我已经得到了bloburl: "mediastream:http://192.168.1.20:3000/1c267861-a2da-41df-9a83-ae69fdfd883b"但我不知道如何从它抓取数据通过套接字发送.IO。

任何帮助将摇滚。

服务器:

 // server.js var http = require('http'); var socketio = require('socket.io') var fs = require('fs'); var server = http.createServer(function (req, res) { if (req.url ==='/') { fs.readFile('index.html', function (err, html) { res.writeHeader(200, {"Content-Type": "text/html"}); res.write(html); return res.end(); }); } else { res.end('hi!'); } }); var io = socketio(server); server.listen(8000, function () { console.log('Jumping on port 8000!'); }); io.on('connection', function (socket) { socket.emit('news', { hello: 'world' }); socket.on('my other event', function (data) { console.log(data); }); socket.on('video', function (video) { console.log(video); }); }); 

客户:

网上收集的解决方案 "如何将video(从getUserMedia)发送到Node.js服务器?"

您可以使用MediaRecorder API来抓取stream和WebSockets,将其发送到node.js

这里有一些细节(链接到我自己的博客): https : //www.webrtcexample.com/blog/?go=all/tutorial-recording-video/

简而言之,MediaRecorder API将一组帧放入您的callback函数中,然后通过WebSockets(或任何其他二进制通道)将帧发送到服务器(node.js)。

它适用于Firefox的完美。 目前为止,Chrome已经实现了MediaRecorder API的实现。
