1.github 下载源码
git clone https://github.com/Netflix/vmaf.git
2.下载build tools meson
https://mesonbuild.com/Getting-meson.html
Meson is available in the Python Package Index and can be installed with pip3 install meson which requires root and will install it system-wide. Alternatively, you can use pip3 install --user meson which will install it for your user and does not require any special privileges. This will install the package in ~/.local/, so you will have to add ~/.local/bin to your PATH.
3.编译 libvmaf
cd vmaf/libvmaf 参考 README.md
meson build –buildtype release
ninja -vC build
sudo ninja -vC build install
4.FFmpeg 使能
./configure --enable-debug=3 --disable-doc --disable-optimizations --enable-pic --extra-cflags=-fPIC --enable-openssl --enable-libx264 --enable-libx265 --enable-gpl --enable-nonfree --enable-libfreetype --enable-libfdk-aac --enable-libaom --enable-libvpx --enable-libopus --enable-libvmaf --enable-version3
make -j8
make install
5.使用
ffmpeg -i xigua_h265.mp4 -i xigua_feijm.mp4 -filter_complex "[0:v]scale=1920x1080:flags=bicubic[main]; [1:v]scale=1920x1080:flags=bicubic,format=pix_fmts=yuv420p,fps=fps=25/1[ref]; [main][ref]libvmaf=psnr=1:phone_model=1:log_fmt=json" -f null - > out.json
其他命令参考：
ffmpeg -i main.mpg -i ref.mpg -lavfi libvmaf -f null - ffmpeg -i main.mpg -i ref.mpg -lavfi libvmaf="psnr=1:log_fmt=json" -f null - ffmpeg -i main.mpg -i ref.mkv -lavfi "[0:v]settb=AVTB,setpts=PTS-STARTPTS[main];[1:v]settb=AVTB,setpts=PTS-STARTPTS[ref];[main][ref]libvmaf=psnr=1:log_fmt=json" -f null -
