peer to peer video streaming service in csharp

To create a peer to peer video streaming service in C#, we need to establish a network between peers to share video data. Here are the general steps:

Establish a TCP or UDP based socket connection between peers.
Design and format a protocol for communication between peers.
Create a buffer to store video data (e.g. buffer for 10 seconds of video).
Encode video data using a video codec, and then compress it.
Break down the video data into packets and send them to the corresponding peer.
At the receiving end, packets should be stored in a buffer.
Decode and decompress video packets, and display the received video stream.

Here's a sample code utilizing C# implementation of RTP (Real-time Transport Protocol) and RTSP (Real-Time Streaming Protocol) libraries to illustrate a basic P2P video streaming service:


main.cs
using System;
using System.Diagnostics;
using System.Linq;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Threading.Tasks;
using RtspClientSharp;

namespace StreamingServer
{
    class Program
    {
        static async Task Main(string[] args)
        {
            var streamingEndpoint = new IPEndPoint(IPAddress.Any, 8554);

            var server = new TcpListener(streamingEndpoint);
            server.Start();

            Console.WriteLine($"Listening on {streamingEndpoint}");

            while (true)
            {
                var client = await server.AcceptTcpClientAsync();

                Console.WriteLine($"Client connected from {client.Client.RemoteEndPoint}");

                var rtspListener = new RtspTcpTransportListener(client.GetStream());
                var rtspServer = new RtspServer(rtspListener);

                rtspServer.ClientConnected += OnClientConnected;
                rtspServer.ClientDisconnected += OnClientDisconnected;

                await rtspServer.StartAsync();

                Console.WriteLine($"client {client.Client.RemoteEndPoint} disconnected");
            }
        }

        private static async Task OnClientConnected(RtspClient client, RtspSession session)
        {
            Console.WriteLine($"client {session.SessionId} connected");
            //Do something here
        }

        private static async Task OnClientDisconnected(RtspClient client, RtspSession session)
        {
            Console.WriteLine($"client {session.SessionId} disconnected");
            //Do something here
        }
    }
}

This is a sample code for server-side implementation that utilizes the RtspClientSharp and RtspServerSharp libraries for RTSP communications. As for the client-side, we can create an analogous application that connects and receives video packets from other peers.
