同时播放音频

Question

我想使用 socket.io 和 socket.io-stream 将音频从 NodeJS 服务器流式传输到客户端浏览器，我成功地做到了，只有一个问题。 首先，这是代码 server.js

const express = require("express");
const app = express();
const server = require("http").Server(app);
const port = process.env.port || 8080;

const path = require("path");
const fs = require("fs");
const io = require("socket.io")(server);
const ss = require("socket.io-stream");

app.use(express.static(path.join(__dirname, "public")));

server.listen(port, () => {
  console.log(`Server listening on ${port}`);
});

io.on("connection", socket => {
  socket.emit("start", { hello: "world!" });
  socket.on("stream", data => {
    let stream = ss.createStream();
    let filename = path.join(__dirname, `/clips/Wegz.mp3`);

    ss(socket).emit("audio-stream", stream, { name: filename });
    fs.createReadStream(filename).pipe(stream);
  });
});

client.js

var socket = io("http://localhost:" + window.location.port);
var audio = document.getElementById("audio");

socket.on("start", function(data) {
  socket.emit("stream", { Data: "you can send any data back" });
  ss(socket).on("audio-stream", function(stream, data) {
    let parts = [];
    stream.on("data", chunk => {
      parts.push(chunk);
    });
    stream.on("end", function() {
      console.log(i);
      audio.src = URL.createObjectURL(new Blob(parts));
      audio.play();
    });
  });
});

这里的问题是我在将所有块推送到列表后播放音频但我想逐块同时播放音频而不等待所有部分被推送。 我希望我澄清了我的问题，任何帮助将不胜感激。

您尝试过这样做吗？ stream.on("data", chunk => { audio.src = URL.createObjectURL(new Blob(parts)); audio.play(); parts.push(chunk); });
