FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

This fork is an updated version of the ossr version that adds WHIP support to FFMPEG.

Compiling this version on Windows with nvenc has only been successfully attempted using MSYS2. Find instructions below.

1. Install MSYS2 from https://msys2.github.io/
2. Install prerequisites in the mingw64 shell:

$ pacman -Syu
$ pacman -S \
    make \
    diffutils \
    yasm \
    nasm \
    pkg-config \
    mingw-w64-x86_64-pkg-config \
    mingw-w64-x86_64-gcc \
    mingw-w64-x86_64-opus \
    mingw-w64-x264 \
    mingw-w64-x86_64-x265

3. Install the NVIDIA CUDA Toolkit
4. Clone the ffnvcodec repository and install it in the mingw64 shell:

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

5. Create a folder named nv_sdk in a path without spaces and copy all files from C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\[version]\include and library files from C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\[version]\lib\x64 to your nv_sdk folder.
6. Create a folder named cuda_sdk in a path without spaces and copy the two folders bin and lib from C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\[version] to your cuda_sdk folder.
7. Launch a VS Developer Command Prompt, navigate to C:\msys64 and launch .\msys2_shell.cmd -use-full-path -mingw64
8. Navigate to your ffmpeg directory and run configure (with adjusted paths!):

$ ./configure \
    --enable-muxer=whip \
    --enable-yasm \
    --enable-asm \
    --enable-openssl \
    --enable-version3 \
    --enable-libx264 \
    --enable-gpl \
    --enable-libx265 \
    --enable-nonfree \
    --enable-cuda-nvcc \
    --enable-libnpp \
    --enable-nvenc \
    --enable-libopus \
    --extra-ldflags="-static -static-libgcc -static-libstdc++ -L/c/Users/[...]/nv_sdk -L/c/Users/[...]/cuda_sdk/lib/x64" \
    --extra-cflags="-I/c/Users/[...]/nv_sdk -I/c/Users/[...]/cuda_sdk/include -I/c/Users/[...]/nv-codec-headers/include" \
    --enable-static \
    --disable-shared \
    --disable-w32threads \
    --pkg-config-flags="--static"

If this command succeeded, continue to compiling:

$ make -j8

Good luck.
