Linux下安装FFmpeg

参考文章

 1. 从github下载源码[FFmpeg-n4.3.1.tar.gz](https://github.com/FFmpeg/FFmpeg/tags)
 2. 上传到服务器解压tar -zxvf FFmpeg-n4.3.1.tar.gz
 3. cd FFmpeg-n4.3.1/
 4. ./configure --prefix=/usr/local/ffmpeg/ffmpeg
 5. make && make install
 6. vim /etc/profile
	export PATH=$PATH:/usr/local/ffmpeg/ffmpeg/bin
	source /etc/profile
 7. ffmpeg -version

注意：

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
