软硬件环境

• ubuntu 18.04 64bit
• nvidia GTX 1070 Ti
• ffmpeg 4.0

nvidia驱动

之前的一篇文章里有详细的安装步骤，http://xugaoxiang.com/post/117

安装ffmpeg依赖库

sudo apt install libfdk-aac-dev libmp3lame-dev libx264-dev libx265-dev libsdl2-dev

安装nvidia codec头文件

git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git
make
sudo make install

NVidia Video Codec SDK

下载地址，https://developer.nvidia.com/nvidia-video-codec-sdk#Download, 解开包，存放到某一目录，如我这的/home/longjing/Tools

ffmpeg编译

下载最新发布的4.0版本，https://ffmpeg.org/releases/ffmpeg-4.0.tar.bz2

./configure --enable-gpl --enable-nonfree --enable-libfdk-aac --enable-libmp3lame --enable-libx264 --enable-libx265 --enable-nvenc --extra-cflags=-I/home/longjing/Tools/Video_Codec_SDK_8.1.24/LegacySamples/common/inc --extra-ldflags=-L/home/longjing/Tools/Video_Codec_SDK_8.1.24/LegacySamples/common/lib/linux/x86_64
make
sudo make install

编译完成后，查看下ffmpeg是否支持nvidia的编解码器
