Jasper Media Player

A modern Windows 11 media player with a Fluent interface, Mica styling, local playback, direct URL playback, and HLS stream support.

---

✨ What is it?

Jasper Media Player is a small Windows 11-style media player built with WinUI 3, Windows App SDK, LibVLCSharp, and VideoLAN.LibVLC.Windows.

It keeps the app simple: open a local media file, paste a direct stream URL, or play an HLS .m3u8 stream without needing to install VLC separately.

This project is not the official VLC desktop app and is not affiliated with VideoLAN. It uses LibVLC/LibVLCSharp packages as playback technology.

🖼️ Features

• Native Windows 11-style interface
• Fluent controls and Mica-like app styling
• Open local video/audio files
• Play direct media URLs such as .mp4, .mp3, and similar files
• Play HLS .m3u8 streams using the native Windows stream renderer
• Play/pause, stop, seek, volume, and time display
• x64 Windows build target
• No separate VLC installation required for normal use

📦 Download

Go to the latest release and download the Windows x64 ZIP:

Download the latest release

After downloading:

1. Extract the ZIP.
2. Open the extracted folder.
3. Run JasperMediaPlayer.exe.

Do not run the app directly from inside the ZIP, and do not move only the EXE by itself. The app needs its included DLLs and media files beside it.

🧪 Stream URL examples

Try these in the URL box:

https://devstreaming-cdn.apple.com/videos/streaming/examples/img_bipbop_adv_example_fmp4/master.m3u8

https://test-streams.mux.dev/x36xhzz/x36xhzz.m3u8

Normal YouTube page links are not direct stream URLs, so they are not expected to work in the URL box.

🛠️ Build from source

Requirements

• Windows 11
• Visual Studio 2022 Community
• WinUI application development workload
• Developer Mode enabled in Windows settings

Visual Studio

1. Clone the repository.
2. Open src/JasperMediaPlayer.sln or src/JasperMediaPlayer.csproj.
3. Set configuration to Release and platform to x64.
4. Build and run.

PowerShell

git clone https://github.com/JasperSoosaar25/JasperMediaPlayer.git
cd JasperMediaPlayer
dotnet restore .\src\JasperMediaPlayer.csproj
dotnet build .\src\JasperMediaPlayer.csproj -c Release -r win-x64

🚀 Make a shareable build

Run:

.\Build.ps1

Or publish manually:

dotnet publish .\src\JasperMediaPlayer.csproj -c Release -r win-x64 --self-contained false -p:WindowsPackageType=None -p:WindowsAppSDKSelfContained=true

Then ZIP the whole publish folder, not just the EXE.
