2K 4K 8K nvdec-play

A reference-grade portable desktop software combining Nvidia hardware decoding (RTX family), Vulkan GPU rendering, advanced mathematical video algorithms, statistical chroma reconstruction. Fixed-grid, edge-aware deblocking and mild detail-restoration GPU shaders. Recommended GPU: RTX 5060 / RTX 5050

🎬 Supported Codecs

MPEG-2, VC-1 (WMV), some MPEG-4, H.264/AVC, H.265/HEVC, VP8, VP9, AV1. NVDEC cannot hardware-accelerate every video codec or every video format / profile.

🧩 Vulkan GLSL Shaders

+ Vulkan DeblockForge-8X8 2.0
+ Vulkan ChromaFromLumaPrediction 1.1

These shaders are only applied when a video is upscaled. More shaders soon.
