VMAF3.0编译及常见问题记录
原创
前沿
VMAF (Video Multi-Method Assessment Fusion) 是 Netflix 开发的开源视频质量评估工具，版本 3.0 是其一个重要更新。它的主要作用是视频质量评估：通过机器学习模型综合多种质量指标，预测人类对视频质量的主观感受，提供 0-100 分的 VMAF 分数，分数越高表示质量越好。另外，它具有多种评估模型，包含手机观看、4K 等不同场景的评估模型。
编译及使用
接下来以 linux 系统为例进行介绍，首先是安装依赖项。
1、安装依赖项
sudo yum groupinstall "Development Tools"
sudo yum install -y git meson nasm doxygen
sudo yum install -y python3 python3-pip python3-setuptools
sudo yum install -y epel-release
sudo yum install -y python3-scipy2、获取 VMAF 源代码
git clone https://github.com/Netflix/vmaf.git
cd vmaf
git checkout v3.0.03、编译
执行如下命令进行代码编译：
cd libvmaf
meson build --buildtype release
ninja -C build
sudo ninja -C build install4、使用
设置动态库链接地址：
echo "/usr/local/lib" | sudo tee /etc/ld.so.conf.d/vmaf.conf
sudo ldconfig执行 vmaf 命令进行验证：
vmaf --version如果需要编译到 ffmpeg 中，需要在执行 configure 命令时 ，指定参数 --enable-libvmaf。
两种使用方式，下面分别介绍。
4.1 直接使用
vmaf -r reference.yuv -d distorted.yuv -w 1920 -h 1080 -p 420 -b 84.2 利用ffmpeg
ffmpeg -i distorted.mp4 -i reference.mp4 -lavfi libvmaf -f null -常见问题
问题一、bash: meson: command not found
执行如下命令报错：
meson setup builddir --default-library=static --prefix=/tools/ffmpeg -Denable_avx512=false解决： sudo yum install meson
问题二、ERROR: Meson version is 0.55.1 but project requires >= 0.56.1

A full log can be found at /tools/vmaf-3.0.0/libvmaf/builddir/meson-logs/meson-log.txt解决：
pip3 install --upgrade meson输出如下信息表示升级成功：
