Features

Check out libvlc-nuget to get a basic understanding of how libvlc works, what it can offer and how to install it with NuGet.

Some of the features include:

• Play every media file formats, every codec and every streaming protocols
• Run on every platform, from desktop (Windows, Linux, Mac) to mobile (Android, iOS) and TVs
• Hardware and efficient decoding on every platform, up to 8K
• Network browsing for distant filesystems (SMB, FTP, SFTP, NFS...) and servers (UPnP, DLNA)
• Playback of Audio CD, DVD and Bluray with menu navigation
• Support for HDR, including tonemapping for SDR streams
• Audio passthrough with SPDIF and HDMI, including for Audio HD codecs, like DD+, TrueHD or DTS-HD
• Support for video and audio filters
• Support for 360 video and 3D audio playback, including Ambisonics
• Able to cast and stream to distant renderers, like Chromecast and UPnP renderers.

Most things you can achieve with the regular VLC desktop app, you can also achieve using libvlc.

Installation

1. Install LibVLC in your platform specific project.

LibVLC is the actual VLC engine written mostly in C/C++ and compiled for your target platform. More information here.

Platform	LibVLC Package	NuGet	Minimum OS Version
Windows	VideoLAN.LibVLC.Windows		Windows XP
UWP	VideoLAN.LibVLC.UWP		Windows 10
Mac	VideoLAN.LibVLC.Mac		macOS 10.7
Android	VideoLAN.LibVLC.Android		Android 2.3
iOS	VideoLAN.LibVLC.iOS		iOS 8.4
tvOS	VideoLAN.LibVLC.tvOS		tvOS 10.2
Linux	Linux guide	N/A	N/A

dotnet add package VideoLAN.LibVLC.[Windows|UWP|Android|iOS|Mac|tvOS]

2. Install LibVLCSharp or LibVLCSharp.Forms (if you plan on using Xamarin.Forms)

LibVLCSharp is the .NET wrapper that consumes LibVLC and allows you to interact with native code from C#/F#.

Pre-release versions

LibVLCSharp 4 preview and LibVLC 4 nightly builds are distributed using https://feedz.io/ for now. To pull pre-release versions into your project, use the following NuGet.config file:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="videolan-preview" value="https://f.feedz.io/videolan/preview/nuget/index.json" />
  </packageSources>
</configuration>

See the docs for preview builds installation details.

Getting started

Follow the Getting started guide. Make sure you read it since it contains platform-specific caveats

Documentation

Our general documentation is part of this repository and we also have an API docs website.

Feel free to browse it and if you see something missing, you can improve it by sending a PR.

It includes helpful documents such as:

Best practices

This document details how to use LibVLCSharp in a correct way, notably taking into consideration the native interop part.

Q&A guide

This is a Q&A document which I compiled from all the questions I got asked regarding LibVLC and LibVLCSharp. Continuously updated.

Troubleshooting issues

When you encounter an issue with LibVLC/LibVLCSharp, identifying the cause is not always straightforward. This document gives you clues on how to go about it.

Libvlc specific information

This page focuses on the core native library and contains information regarding advanced libvlc configuration and its versioning strategy by VideoLAN.

Tutorials

This page indexes all available tutorial materials about LibVLCSharp. There are currently videos, talks, blogposts and code samples.

Community projects

Here we list several interesting projects made by the community using LibVLCSharp. Feel free to send a PR to yours!

Ebook

In September 2022, the first book ever about LibVLC, the VideoLAN community and LibVLCSharp was released!

The Good Parts of LibVLC contains everything you need to know about VLC, LibVLC and how to use it from .NET with LibVLCSharp.

Samples

For more advanced samples, have a look at libvlcsharp-samples with apps such as:

• Chromecast sample: Discover chromecasts on your local network and select one for playback in 100% shared code (Xamarin.Forms, iOS/Android).
• Record HLS sample: Simple .NET Core CLI app which shows how to record an HLS stream to the filesystem.
• RTSP Mosaic sample: Cross-platform RTSP player sample with 4 views mosaic (Xamarin.Forms, iOS/Android).

• LocalNetwork sample: Cross-platform local network browsing and playback with network shares (SMB, UPnP) on Android, iOS and WPF.
• MediaPlayerElement sample: Minimal iOS/Android sample showing how to get started with the crossplatform MediaPlayerElement control from LibVLCSharp.Forms.
• SkiaSharp Preview Thumbnailer sample: .NET Core sample app showing how to use LibVLC 3 video callbacks and encode the frame with SkiaSharp before saving it to disk.
• lvst: Watch a movie while it is downloading! lvst is a .NET Core CLI app using MonoTorrent and LibVLCSharp for macOS, Linux and Windows.

Quick API overview

using var libvlc = new LibVLC(enableDebugLogs: true);
using var media = new Media(libvlc, new Uri(@"C:\tmp\big_buck_bunny.mp4"));
using var mediaplayer = new MediaPlayer(media);

mediaplayer.Play();

Console.ReadKey();

• LibVLC.cs: Main object pointing to a native libvlc instance in native code.
• MediaPlayer.cs: Manages playback, offers event listeners and more. Accessible from VideoView with data-binding support.
• Media.cs: Class representing and providing information about a media such as a video or audio file or stream.
• VideoView.cs: Custom native view which holds a MediaPlayer object.
• MediaDiscoverer.cs: This object should be used to find media on NAS and any SMB/UPnP-enabled device on your local network.
• RendererDiscoverer.cs: Use this to find and use a Chromecast or other distant renderers.
• Dialog.cs: Dialogs can be raised from the libvlc engine in some cases. Register callbacks with this object.

The LibVLCSharp.Forms and Uno packages features a MediaPlayerElement control, similar to the ones provided by the .NET Framework on WPF and UWP. It currently supports iOS, Android and UWP (Uno only).

Roadmap

• Game engines (Unity, Unreal, Godot)
• LibVLC 4 support

If you have a request or question regarding the roadmap, feel free to open an issue (using an issue template) or PR.

Versioning

As this is a libvlc binding, we try to follow the libvlc versioning scheme as much as possible. The versioning strategy is explained in the versioning document.
