步骤 1: 安装必要的依赖

sudo apt update
sudo apt install -y \autoconf automake build-essential cmake git libass-dev libfreetype6-dev \libsdl2-dev libtool libva-dev libvdpau-dev libxcb1-dev libxcb-shm0-dev \libxcb-xfixes0-dev pkg-config texinfo wget zlib1g-dev nasm yasm \libx264-dev libx265-dev libnuma-dev libvpx-dev libfdk-aac-dev libmp3lame-dev \libopus-dev libaom-dev libdav1d-dev

其中libaom-dev、 libdav1d-dev以及libfdk-aac-dev可能需要源码安装

libaom-dev源码安装

git clone https://aomedia.googlesource.com/aom
cd build/
cmake .. -DENABLE_NASM=on -DCMAKE_INSTALL_PREFIX=/usr/local
make -j$(nproc)
sudo make install

libdav1d-dev 源码安装

git clone https://salsa.debian.org/multimedia-team/dav1d.git
sudo apt install meson
meson setup ..
ninja
ninja install

libfdk-aac-dev源码安装

git clone https://github.com/mstorsjo/fdk-aac.git
cd fdk-aac/
autoreconf -fiv
./configure --prefix=/usr/local
make -j$(nproc)
sudo make install

步骤2 编译安装ffmpeg

git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
cd ffmpeg./configure \--prefix=/usr/local \--enable-gpl \--enable-nonfree \--enable-libx264 \--enable-libx265 \--enable-libvpx \--enable-libfdk-aac \--enable-libmp3lame \--enable-libopus \--enable-libdav1d \--enable-libaom \--enable-nvenc \--enable-vaapi \--enable-libass \--enable-libfreetype \--enable-libxcb \--enable-libdrm
make -j$(nproc)
sudo make install

• AV1 支持：–enable-libdav1d（解码）和 --enable-libaom（编码）
• NVENC：–enable-nvenc 用于 NVIDIA 的硬件加速
• VAAPI：–enable-vaapi 用于 Intel 和 AMD 的硬件加速

步骤 3: 验证安装

ffmpeg -encoders | grep av1
ffmpeg -encoders | grep nvenc
ffmpeg -decoders | grep vaapi

设置.bashrc

打开.bashrc 添加export LD_LIBRARY_PATH=/usr/local/lib/x86_64-linux-gnu:/usr/local/lib/:$LD_LIBRARY_PATH
