wget https://ffmpeg.org//releases/ffmpeg-6.1.1.tar.gz tar -zxvf ffmpeg-6.1.1.tar.gz进入解压后目录,输入如下命令/usr/local/ffmpeg为自己指定的安装目录
cd ffmpeg-6.1.1 ./configure --prefix=/usr/local/ffmpeg make && make install这里可能会遇到问题， 可以参考下边对应的解决方案
配置环境变量
vi /etc/profile # 在最后PATH添加环境变量： export PATH=$PATH:/usr/local/ffmpeg/bin # 保存退出 :wq # 查看是否生效 source /etc/profile 设置生效查看版本
ffmpeg -version 查看版本遇到的问题
问题一
nasm/yasm not found or too old. Use --disable-x86asm for a crippled build. If you think configure made a mistake, make sure you are using the latest version from Git. If the latest version fails, report the problem to the ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat. Include the log file "ffbuild/config.log" produced by configure as this will help solve the problem.解决方案
分析：yasm是汇编编译器，ffmpeg为了提高效率使用了汇编指令，如MMX和SSE等。所以系统中未安装yasm时，就会报上面错误。
解决错误：安装yasm编译器。安装方法如下
yasm官网

wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz tar -zxvf yasm-1.3.0.tar.gz cd yasm-1.3.0 ./configure make && make install问题二
若运行 ffmpeg -i 报错误：
ffmpeg: error while loading shared libraries: libiconv.so.2: cannot open shared object file: No such file or directory
安装 libiconv.so.2
#下载libiconv wget https://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.16.tar.gz tar -zxvf libiconv-1.16.tar.gz cd libiconv-1.16 #编译安装 ./configure --prefix=/usr/local make make_install ln -s /usr/local/lib/libiconv.so.2 /usr/lib/libiconv.so.2 ldconfig
