Prerequisites

• Setup MSYS2 environment (refer to this wiki)

Clone the source

git clone git://source.ffmpeg.org/ffmpeg

Alternative options

• mirror on github: https://github.com/FFmpeg/FFmpeg.git
• Microsoft interop project at https://github.com/microsoft/FFmpegInterop

  git clone --recursive git://github.com/microsoft/FFmpegInterop.git
  

Install packages

normal msys2 packages

pacman -S make pkg-config diffutils

mingw-w64 packages and toolchains

pacman -S mingw-w64-x86_64-nasm mingw-w64-x86_64-gcc mingw-w64-x86_64-SDL2

Build using MINGW-W64

configure, this step may take quite some minutes

./configure

build, as said in the official instructions, use make -r to speed up the time for re-building

make -r 

Build using MSVC

Refer to the the official instructions, the configure step needs an extra parameter

./configure --toolchain=msvc

Build with GPU acceleration support

Reference the official instructions

1. Download and install the CUDA toolkit
2. Install Microsoft Visual Studio VC tools
3. Open a VC Command Prompt (e.g. "x64 Native Tools Command Prompt for VS 2019"), add two paths

   set INCLUDE=%INCLUDE%;%CUDA_PATH%\include
   set LIB=%LIB%;%CUDA_PATH%\lib\x64
   

4. Open MSYS shell by executing the msys_shell.bat
5. Clone and enable ffnvcodec header

   git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git
   cd nv-codec-headers
   make
   make install PREFIX=/usr
   

6. configure including CUDA headers

   cd ~/ffmpeg
   ./configure --toolchain=msvc --arch=x86_64 --enable-cuda --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp 
   

7. make

   make -j 10
