FFmpeg Static Libraries for Windows

Pre-built FFmpeg 7.0.3 static libraries compiled with MSVC /MT runtime.

Slim build for nxemu Host1x / NVDEC: H.264, HEVC, VP8, VP9 decode, yadif, swscale, D3D11VA/DXVA2. No debug symbols (--disable-debug). Rebuild from D:\Dev\ffmpeg-7.0.3 with build_msvc_mt.bat.

Contents

• libavcodec.lib - Encoding/decoding
• libavfilter.lib - Filters (yadif deinterlace)
• libavutil.lib - Utilities
• libswscale.lib - Scaling/conversion (VIC)

libavformat.lib, libavdevice.lib, and libswresample.lib are also installed so existing Visual Studio link lines keep working.

Configuration

• FFmpeg version: 7.0.3
• Compiler: MSVC (Visual Studio 2022)
• Runtime: /MT (static)
• Platform: x64
• Debug symbols: disabled

Usage in Visual Studio

1. Add to Additional Include Directories: $(SolutionDir)external\ffmpeg\include
2. Add to Additional Library Directories: $(SolutionDir)external\ffmpeg\lib
3. Add to Additional Dependencies: libavcodec.lib libavfilter.lib libavutil.lib libswscale.lib
4. Set Runtime Library to /MT

macOS Apple Silicon

On an Apple Silicon Mac, rebuild the archives with:

./build_macos_arm64.sh

The script writes these files to lib/macos-arm64/:

• libavcodec.a
• libavfilter.a
• libavutil.a
• libswscale.a
• BUILDINFO.txt

The macOS build is intentionally minimal: static ARM64 libraries with the H.264, HEVC, VP8 and VP9 decoders, the yadif filter, and swscale. VideoToolbox is enabled explicitly for H.264 and VP9; unsupported streams retain software decoding. CMake links the CoreFoundation, CoreMedia, CoreVideo and VideoToolbox frameworks. The rebuild checks that the requested hardware accelerators were enabled before installing the archives. Automatic external-library detection is disabled so a rebuild cannot silently acquire Homebrew or MacPorts dependencies.

MACOSX_DEPLOYMENT_TARGET may be set when rebuilding. It defaults to 11.0, the first macOS release supporting Apple Silicon.
