下载解压
wget http://www.ffmpeg.org/releases/ffmpeg-7.0.1.tar.xz
tar -Jxvf ffmpeg-7.0.1.tar.xz
编译安装
cd ffmpeg-7.0.1/
sudo ./configure --prefix=/usr/local/ffmpeg
若安装过程中出现以下错误:
yasm/nasm not found or too old. Use –disable-yasm 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.freenode.net.
Include the log file “config.log” produced by configure as this will help
solve the problem.
如出现报错信息需先解决后再继续执行。
安装yasm:
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
提示:解决上述错误之后,重新执行
cd ffmpeg-7.0.1/
sudo ./configure --prefix=/usr/local/ffmpeg
-----编译安装(过程较慢,耐心等待)
make && make install
安装完成,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,设置生效
source /etc/profile
ffmpeg -version 查看版本
使用:
--将mp4的视频转为采样率16k、位长16bit、单声道的wav音频
./ffmpeg -i 示例视频5.mp4 -ar 16000 -ac 1 -ab 16k aaa.wav
