    Changelog

    • Core: Fix playback deadlocks, race conditions and decoder lifecycle synchronization
    • FlyleafHost.Wpf: Fixes a DPI issue

    Deadlock & Race Condition Fixes

    • Fixed several deadlocks and race conditions affecting playback, seeking, stream switching, and decoder lifecycle.
    • Fixed audio decoder lock leaks caused by early exits during decoding and filter processing.
    • Improved decoder/demuxer thread synchronization during Start, Stop, Pause, and restart operations.
    • Fixed concurrent Play/Pause/Seek races, including duplicate playback workers and interrupted initialization.
    • Resolved lock-order inversions between decoder opening, seeking, and codec reopening.
    • Improved seek handling by ensuring decoders are properly paused before seeking and restarted when required.
    • Improved FFmpeg context lifetime safety by synchronizing decoder and demuxer disposal.
    • Fixed a native crash caused by video stream switching overlapping paused-seek frame extraction (GetVideoFrame()).
    • Improved stability when handling network streams, torrents, rapid seeking, and stream switching.

    lyleaf v3.11: Media Player .NET Library

    alt text

    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
