1、windows 安装

配置环境变量：D:\ffmpeg-4.3.1\bin

dos窗口输入 ffmpeg -version 命令，如有信息则说明成功

2、Linux 安装

# wget http://www.ffmpeg.org/releases/ffmpeg-4.3.tar.gz
# tar -zxvf ffmpeg-4.3.tar.gz
# cd ffmpeg-4.3
# ./configure --prefix=/usr/local/ffmpeg
# make && make install
 
等待安装完成...
 
# vi /etc/profile
在最后PATH添加环境变量：
PATH=$PATH:/usr/local/ffmpeg/bin
export PATH
保存退出
 
# source /etc/profile   设置生效
# ffmpeg -version       查看版本

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.

需要安装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

结束！

3、JAVA 调用（第三方包 jave-1.0.2.jar）
