javascript – 从套接字连接收集的二进制数据生成视频文件

我已经创建了一个套接字连接,并使用该连接将二进制流数据发送到服务器,在服务器端,我现在正在使用该数据获取二进制数据,我想创建一个视频文件并将其保存在服务器上.我成功地获得二进制数据现在没有任何方式将其转换为视频文件.请帮助实现.

在服务器端m使用node.js创建套接字服务器并从客户端javascript

服务器端代码：

var server = http.createServer(function(request, response) {
    //Creating websocket server
});
server.listen(1337, function() { }); // listen to 1337 port

// create the server
wsServer = new WebSocketServer({
    httpServer: server
});

// WebSocket server
wsServer.on('request', function(request) {
    var connection = request.accept(null, request.origin);

    // all messages from client will receive here.
    connection.on('message', function(message) {
      if (message.type === 'utf8') {

      }else if (message.type === 'binary') {
           //here i will get the binary data not want to create the video file using this
      }
    });

    connection.on('close', function(connection) {


    });

})

客户端 ：

window.WebSocket = window.WebSocket || window.MozWebSocket;
    var connection = new WebSocket('ws://localhost:1337');
    connection.binaryType = 'arraybuffer';
    var options = {
      mimeType: 'video/webm;codecs=vp9'
    };

    mediaRecorder = new MediaRecorder(MediaStream, options);
    mediaRecorder.ondataavailable = function(event) {
      if (event.data.size > 0) {
        recordedChunks.push(event.data);
         connection.onopen = function () {
            var byteArray = new Uint8Array(event.data);
            connection.send(byteArray.buffer);
         };
      }
    };

解决方法:

我已经成功地在服务器上创建了视频文件我已经使用recordRTC api将视频流转换为dataurl并使用socket.io发送到服务器,并在服务器上将dataurl转换为base64并将其写入文件.

这是我的客户端代码.

socketio = io("ws://192.168.0.42:1337");
  recordVideo = RecordRTC(MediaStream, {type: 'video'});
  recordVideo.startRecording();
  onStopRecording();
  function onStopRecording(){
      recordVideo.stopRecording(function() {
        recordVideo.getDataURL(function(videoDataURL) {
                  var d = new Date();
                   var files = {
                       video: {
                           type: recordVideo.getBlob().type || 'video/webm',
                           dataURL: videoDataURL,
                           time : d.getTime()
                       }
                   };
                   socketio.emit('message', files);
         })
      });
  }

从服务器端：

var server = http.createServer(function(request, response) {
    //Creating websocket server
});
server.listen(1337, function() { }); // listen to 1337 port


var wIoSocket = io.listen(server);
wIoSocket.sockets.on('connection', function (socket) {
    socket.on('message', function (data) {
        if (data.video) {
            writeToDisk(data.video.dataURL, data.video.time+'.webm');
        }
    });
});


function writeToDisk(dataURL, fileName) {
    var dataURL = dataURL.split(',').pop();
    var fileBuffer = new Buffer(dataURL, 'base64');
    fs.writeFileSync(fileName, fileBuffer);
}
