ffmpeg 是一个处理媒体文件的命令行工具 (command line based) 。它是一个拥有非常多功能的框架，并且因为他是开源的，很多知名的工具如 VLC，YouTube， iTunes 等等，都是再其之上开发出来的。我们项目需要针对视频文件进行缩略图截帧操作，所以记述一下安装过程。

8.1 前提安装yasm

[root@ecs-s6 J2EETool]# wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
[root@ecs-s6 J2EETool]# tar -zxvf yasm-1.3.0.tar.gz
[root@ecs-s6 J2EETool]# cd yasm-1.3.0
[root@ecs-s6 yasm-1.3.0]# ./configure
[root@ecs-s6 yasm-1.3.0]# make
[root@ecs-s6 yasm-1.3.0]# make install

8.2 安装ffmpeg4.2

[root@ecs-s6 J2EETool]# wget http://ffmpeg.org/releases/ffmpeg-4.2.tar.gz
[root@ecs-s6 J2EETool]# tar -zxvf ffmpeg-4.2.tar.gz
[root@ecs-s6 J2EETool]# cd ffmpeg-4.2
[root@ecs-s6 ffmpeg-4.2]# ./configure
[root@ecs-s6 ffmpeg-4.2]# make
[root@ecs-s6 ffmpeg-4.2]# make install

ffmpeg的编译较长，中间请耐心等待。

8.3 安装结果确认：ffmpeg -version

[root@ecs-s6 ffmpeg-4.2]# ./ffmpeg -version
ffmpeg version 4.2 Copyright (c) 2000-2019 the FFmpeg developers
built with gcc 4.8.5 (GCC) 20150623 (Red Hat 4.8.5-39)
configuration: 
libavutil      56. 31.100 / 56. 31.100
libavcodec     58. 54.100 / 58. 54.100

libswresample   3.  5.100 /  3.  5.100
[root@ecs-s6 ffmpeg-4.2]#

8.4 ffmpeg命令使用示例

# 视频截图：
ffmpeg -i /home/test/CZ002.mp4 -y -f image2 -ss 8 -frames 1 ./CZ002.jpg
# 从视频前10s中提取图像，1s提取一帧
ffmpeg -i /home/test/CZ002.mp4 -t 10 -r 1 -f image2 pic-%03d.jpeg
# 音频转换16位
ffmpeg -i /home/test/REC002.WAV -ar 16000 -ab 24k -ac 1 /home/test/RECORD00224.wav
ffmpeg -i /home/test/REC002.WAV -ar 16000 -ab 64k -ac 1 /home/test/RECORD00264.wav

执行命令结果：

[root@ecs-s6 ffmpeg-4.2]# ./ffmpeg -i /home/test/CZ002.mp4 -y -f image2 -ss 8 -frames 1 /home/test/CZ002.jpg
