Live-Streaming-Server-Net

This repository contains an implementation of RTMP server which allows you to build your own live streaming server using .NET.

A more detailed documentation is currently under construction.

Features

RTMP/RTMPS protocol: Supports the RTMP and RTMPS protocols for streaming audio, video, and data.
HTTP-FLV/WebSocket-FLV with ASP.NET CORE: Provides support for serving FLV live streams using HTTP-FLV and WebSocket-FLV protocols within an ASP.NET Core application.
Transmuxing RTMP streams into HLS/DASH streams: Allows you to transmux RTMP streams into HLS (HTTP Live Streaming) or DASH (Dynamic Adaptive Streaming over HTTP) streams.
GOP caching: Supports caching the Group of Pictures (GOP) to ensure immediate availability of live streaming content.
Custom authorization: Enables you to implement custom authorization mechanisms for accessing live streams.
Admin panel: Includes an admin panel that provides an user interface for managing and monitoring the live streaming server.
Cloud Storage Integration: Enabling real-time uploading of HLS files to cloud storage services like Azure Blob Storage, Google Cloud Storage, and AWS S3, which ensures scalable and efficient HLS stream distribution through CDN.

In-Progress

Custom Kubernetes Operator and Kubernetes Integration: The objective is to achieve automatic horizontal autoscaling by scaling out the pods when more streams are published, and scaling in the pods when streams are deleted, all without affecting the existing connections.
Redis Integration: Integrate with Redis to share stream information among pods in the fleet.

Roadmap

Edge Server: Although edge servers are not necessary for serving HLS, they are required for serving RTMP and FLV streams in a cluster configuration.

Quick Start

Run the RTMP Server

Create a .NET 8 console application project and add the dependencies

dotnet new console
dotnet add package LiveStreamingServerNet
dotnet add package Microsoft.Extensions.Logging.Console

Program.cs

using LiveStreamingServerNet;
using Microsoft.Extensions.Logging;
using System.Net;

using var server = LiveStreamingServerBuilder.Create()
    .ConfigureLogging(options => options.AddConsole())
    .Build();

await server.RunAsync(new IPEndPoint(IPAddress.Any, 1935));

Run the application

dotnet run

Publish a Live Stream

With FFmpeg

Use the following command to publish a video as the live stream using FFmpeg

ffmpeg -re -i <input_file> -c:v libx264 -c:a aac -f flv rtmp://localhost:1935/live/demo

With OBS Studio

Open OBS Studio and go to "Settings".
In the "Settings" window, select the "Stream" tab.
Choose "Custom" as the "Service".
Enter "Server": rtmp://localhost:1935/live and "Stream Key": demo.
Click "OK" to save the settings.
Click the "Start Streaming" button in OBS Studio to begin sending live stream to the RTMP server.

Play the Live Stream

With FFplay

Use the following command to play the live stream using FFplay

ffplay rtmp://localhost:1935/live/demo

With VLC Media Player

Open VLC Media Player.
Go to the "Media" menu and select "Open Network Stream".
In the "Network" tab, enter the URL: rtmp://localhost:1935/live/demo.
Click the "Play" button to start playing the live stream.

Serve FLV Live Streams

Create a ASP.NET CORE 8 Web API application project and add the dependencies

dotnet new webapi
dotnet add package LiveStreamingServerNet
dotnet add package LiveStreamingServerNet.Flv

Program.cs

using System.Net;
using LiveStreamingServerNet;
using LiveStreamingServerNet.Flv.Installer;
using LiveStreamingServerNet.Networking.Helpers;

using var liveStreamingServer = LiveStreamingServerBuilder.Create()
    .ConfigureRtmpServer(options => options.AddFlv())
    .ConfigureLogging(options => options.AddConsole())
    .Build();

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddBackgroundServer(liveStreamingServer, new IPEndPoint(IPAddress.Any, 1935));

var app = builder.Build();

app.UseWebSockets();
app.UseWebSocketFlv(liveStreamingServer);

app.UseHttpFlv(liveStreamingServer);

await app.RunAsync();

Run the application

dotnet run --urls="https://+:8080"

Play FLV Live Streams

Given a live stream is published to rtmp://localhost:1935/live/demo

HTTP-FLV

https://localhost:8080/live/demo.flv

WebSocket-FLV

wss://localhost:8080/live/demo.flv
