1. 依赖于 NVIDIA

Nvidia 显卡驱动(.run文件安装)
CUDA Toolkit(.run文件安装)

安装Nvidia驱动(run文件)

  
# 禁用 nouveau 开源驱动
cat > /etc/modprobe.d/blacklist-nouveau.conf <<EOF
blacklist nouveau
options nouveau modeset=0
EOF

# Update initramfs
update-initramfs -u

# 需要重启生效
reboot

# Install compilation tools and Xorg dependencies
apt install -y make gcc linux-headers-$(uname -r) pkg-config xserver-xorg xorg-dev

# Install Vulkan and GLVND development libraries
apt install -y libvulkan1 libglvnd-dev

systemctl stop gdm.service

./NVIDIA-Linux-x86_64-xxx.run

安装CUDA：

  
# https://developer.nvidia.com/cuda-toolkit-archive
wget https://developer.download.nvidia.com/compute/cuda/12.6.3/local_installers/cuda-repo-debian12-12-6-local_12.6.3-560.35.05-1_amd64.deb
sudo dpkg -i cuda-repo-debian12-12-6-local_12.6.3-560.35.05-1_amd64.deb
sudo cp /var/cuda-repo-debian12-12-6-local/cuda-*-keyring.gpg /usr/share/keyrings/
sudo add-apt-repository contrib
sudo apt-get update
sudo apt-get -y install cuda-toolkit-12-6

查看硬件编解码实时状态:

  
watch -n 1 nvidia-smi -i 0 -q -d UTILIZATION

资料:

2. FFMPEG 编译依赖库安装

  
sudo apt-get -y install autoconf automake build-essential libass-dev libfreetype6-dev libsdl2-dev libtheora-dev libtool libva-dev libvdpau-dev libvorbis-dev libxcb1-dev libxcb-shm0-dev libxcb-xfixes0-dev pkg-config texinfo zlib1g-dev

sudo apt-get -y install yasm nasm
sudo apt-get -y install libx264-dev libx265-dev libvpx-dev libdav1d-dev # video
sudo apt-get install libfdk-aac-dev libmp3lame-dev libopus-dev libopus-dev # audio

3. 编译 FFMPEG

  
git clone https://github.com/FFmpeg/nv-codec-headers.git
cd nv-codec-headers
make
sudo make install PREFIX=/usr # 如果安装到其他目录，需要将路径天骄到PKG_CONFIG_PATH

  
./configure --extra-cflags="-I/usr/local/cuda/include" --extra-ldflags="-L/usr/local/cuda/lib64" --extra-libs=-lpthread --extra-libs=-lm --enable-shared  --enable-gpl --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libx264 --enable-libx265 --enable-nonfree --enable-cuda --enable-cuvid --enable-nvenc --enable-ffnvcodec --enable-cuvid # --enable-libfdk_aac --enable-libnpp 

make -j$(nproc)
sudo make install

4. 测试

  
# https://github.com/omen23/ffmpeg-ffnvcodec-explanation
ffmpeg -hide_banner -encoders  | grep nvenc
ffmpeg -hide_banner -decoders | grep cuvid
ffmpeg -hide_banner -hwaccels

# https://d2axc7bbtmotmv.cloudfront.net/chrome_test/Temple.mp4
ffmpeg -c:v h264_cuvid -i input output.mkv # 使用 nvidia cuvid 解码

# 拉流，使用cuda硬件解码
ffmpeg -hwaccel cuda -i https://d2axc7bbtmotmv.cloudfront.net/chrome_test/Temple.mp4 out.mp4 out.mp4

# 拉流，使用nvdec硬件解码
ffmpeg -c:v h264_cuvid -i https://d2axc7bbtmotmv.cloudfront.net/chrome_test/Temple.mp4 out.mp4 out.mp4

# 使用nvenc硬件编码
ffmpeg -i input.mp4 -c:v h264_nvenc output.mp4

6. 附加

VAAPI相关的一些可能的设置选项:

  
sudo apt install xserver-xorg-video-nvidia

# export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libEGL.so

export VDPAU_DRIVER=nvidia
export LIBVA_DRIVER_NAME=nvidia # vdpau
export LIBVA_DRIVERS_PATH=/usr/lib/x86_64-linux-gnu/dri # nvidia_drv_video.so
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export DRI_PRIME=1

export VK_DRIVER_FILES=/usr/lib/x86_64-linux-gnu/libvulkan.so
export VK_ICD_FILENAMES=/usr/share/vulkan/icd.d/nvidia_icd.json
VK_ADD_DRIVER_FILES=/run/opengl-driver/share/vulkan/icd.d/nvidia_icd.x86_64.json

LIBVA_DRI3_DISABLE=1

Nvidia相关的一些可能的环境变量:

  
export __NV_PRIME_RENDER_OFFLOAD=1 
export __GLX_VENDOR_LIBRARY_NAME=nvidia

export __NV_PRIME_RENDER_OFFLOAD=1 
export __VK_LAYER_NV_optimus=NVIDIA_only

export __GLX_VENDOR_LIBRARY_NAME=nvidia
export __EGL_VENDOR_LIBRARY_NAME=nvidia
