Нижняя задержка WEBRTC как можно больше [закрыто] ⇐ Html

[Anonymous]

Ниже находится мой сервер Node-JS webrtc, и мне интересно, как я могу получить наименьшее количество задержек паря между клиентами. При просмотре трансляции из разных сетей существует около 0,7 -секундной задержки. Вещи, которые я сделал до сих пор, в виртуальной камере OBS понижает мое разрешение как можно больше и снижает кадров до 30. Я также добавил сервер поворота для надежности. < /P>
server.js
const express = require("express");
const http = require("http");
const socketIo = require("socket.io");

const app = express();
const server = http.createServer(app);
const io = socketIo(server);

let broadcaster;
const port = 4000;

io.sockets.on("error", (e) => console.log(e));
io.sockets.on("connection", (socket) => {
console.log("A user connected:", socket.id, socket.handshake.address);

socket.on("broadcaster", () => {
broadcaster = socket.id;
socket.broadcast.emit("broadcaster");
console.log(socket.id, "is broadcasting");
});

socket.on("watcher", () => {
console.log(socket.id, "is watching");
socket.to(broadcaster).emit("watcher", socket.id);
});

socket.on("offer", (id, message) => {
socket.to(id).emit("offer", socket.id, message);
console.log(socket.id, "sent an offer to", id);
});

socket.on("answer", (id, message) => {
socket.to(id).emit("answer", socket.id, message);
console.log(socket.id, "sent an answer to", id);
});

socket.on("candidate", (id, message) => {
socket.to(id).emit("candidate", socket.id, message);
console.log(socket.id, "sent a candidate to", id);
});

socket.on("disconnect", () => {
console.log("A user disconnected:", socket.id);
socket.to(broadcaster).emit("disconnectPeer", socket.id);
});
});

server.listen(port, "0.0.0.0", () =>
console.log(`Server is running on http://0.0.0.0:${port}`)
);
