LsmasSharp is a .NET video/audio provider that ports the LWLibavSource and LWLibavAudioSource behavior from L-SMASH-Works into a standalone library. It does not require VapourSynth at runtime. The managed NuGet package is native-free; applications load lsmasnative explicitly when they need decoding.
The native build currently targets Windows x64 and links against the FFmpeg lsmas fork used by L-SMASH-Works.
