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

sudo apt-get install libasound2-dev
sudo apt-get install libgl1-mesa-dev
sudo apt-get install libglew-dev
sudo apt-get install libglm-dev
sudo apt-get install mercurial libnuma-dev

用到汇编相关的程序  nasm
wget https://www.nasm.us/pub/nasm/releasebuilds/2.14.02/nasm-2.14.02.tar.bz2
tar jxvf nasm-2.14.02.tar.bz2

./autogen.sh
./configure --prefix="$HOME/ffmpeg6.0_build" --bindir="$HOME/ffmpeg6.0_bin"
make -j4
make install
ln -s $HOME/ffmpeg6.0_bin/nasm /usr/bin/nasm
同样汇编库  Yasm
wget -O yasm-1.3.0.tar.gz https://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar xzvf yasm-1.3.0.tar.gz
cd yasm-1.3.0

ffmpeg6.0的安装
cd ~/ffmpeg6.0_sources
git clone https://github.com/FFmpeg/FFmpeg.git
cd FFmpeg
git checkout remotes/origin/release/6.0
PKG_CONFIG_PATH="$HOME/ffmpeg6.0_build/lib/pkgconfig" ./configure  --prefix="$HOME/ffmpeg6.0_build"  --extra-libs="-lpthread -lm"  --bindir="$HOME/ffmpeg6.0_bin"  --pkg-config-flags="--static"  --extra-cflags="-I/home/ubuntu/ffmpeg6.0_build/include"  --extra-cflags="-I/home/ubuntu/ffmpeg6.0_build/include/fdk-aac"  --extra-ldflags="-L/home/ubuntu/ffmpeg6.0_build/lib"  --enable-gpl  --enable-libass  --enable-libfreetype  --enable-libvorbis  --enable-pic  --enable-shared  --enable-static  --enable-nonfree  --enable-libx264  --enable-libx265  --enable-libvpx  --enable-libfdk-aac  --enable-libmp3lame  --enable-libopus --enable-sdl2 --enable-ffplay --disable-optimizations --disable-stripping --enable-debug=3
解决ERROR: libmp3lame >= 3.98.3 not found 问题 
--extra-ldflags=-L/home/ubuntu/ffmpeg6.0_build/lib
编辑和修改/etc/ld.so.conf
sudo vim /etc/ld.so.conf
增加
/home/ubuntu/ffmpeg6.0_build/lib
使环境变量生效，然后：
sudo ldconfig
添加环境变量，⽐如
sudo vim /etc/profile
然后加上
export PATH=$PATH:/home/ubuntu/ffmpeg6.0_bin
source /etc/profile

#使用hash -d存入缓存，下次不再查找相关系统路径，直接访问缓存
hash -d ffmpeg
ln -s /home/ubuntu/ffmpeg6.0_bin/ffmpeg /usr/bin/ffmpeg
