Flyleaf

lyleaf v3.11: Media Player .NET Library

---

Notes

1. FlyleafLib’s releases will be on NuGet
2. Compiled samples will be on GitHub releases
3. Documentation will be on Wiki and Samples within the solution

[Overview]

✅ Play Everything _{(Audio, Videos, Images, Playlists over any Protocol)}

• Extends FFmpeg’s supported protocols and formats with additional plugins _{(YoutubeDL, TorrentBitSwarm)}
• Accepts Custom I/O Streams and Plugins to handle non-standard protocols / formats

✅ Play it Smoothly _{(Even with high resolutions 8K / HDR)}

• Coded from scratch to gain the best possible performance with FFmpeg & DirectX using video acceleration and custom pixel shaders
• Threading implementation with efficient cancellation which allows fast open, play, pause, stop, seek and stream switching

✅ Develop it Easy

• Provides a DPI aware, hardware accelerated Direct3D Surface (FlyleafHost) which can be hosted as normal control to your application and easily develop above it your own transparent overlay content
• All the implementation uses UI notifications (PropertyChanged / ObservableCollection etc.) so you can use it as a ViewModel directly
• For WPF provides a Control (FlyleafME) with all the basic UI sub-controls (Bar, Settings, Popup menu) and can be customized with style / control template overrides
