This open-source project provides an implementation of an RTMP live streaming server which allows you to build your own live streaming server using .NET.
- 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.
- Remuxing RTMP streams into HLS/DASH streams: Allows you to remux 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.
- Custom Kubernetes Operator: The objective is to achieve 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.
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;
await using var server = LiveStreamingServerBuilder.Create()
.ConfigureLogging(options => options.AddConsole())
.Build();
await server.RunAsync(new IPEndPoint(IPAddress.Any, 1935));
Run the application
dotnet run
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
- 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.
Use the following command to play the live stream using FFplay
ffplay rtmp://localhost:1935/live/demo
- 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.
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;
var builder = WebApplication.CreateBuilder(args);
await using var liveStreamingServer = LiveStreamingServerBuilder.Create()
.ConfigureRtmpServer(options => options.AddFlv())
.ConfigureLogging(options => options.AddConsole())
.Build();
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"
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
