linux下安装ffmpeg
ffmpeg 可以获取视频文件相关信息 比如视频时间长 ffmpeg -i 文件地址 2>&1 | grep 'Duration' | cut -d ' ' -f 4 | sed s/,//
返回格式 00:01:37.77
一、centos linux下安装ffmpeg
1、下载解压
wget http://www.ffmpeg.org/releases/ffmpeg-3.1.tar.gz
tar -zxvf ffmpeg-3.1.tar.gz
2、 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-3.1
./configure --prefix=/usr/local/ffmpeg
make && make install
3、配置变量
vi /etc/profile
在最后PATH添加环境变量:
export PATH=$PATH:/usr/local/ffmpeg/bin
保存退出
查看是否生效
source /etc/profile 设置生效
4、查看版本
ffmpeg -version 查看版本
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
