CentOS下yum安装ffmpeg/mencoder/mplayer
[dag]name=Dag RPM Repository for Red Hat Enterprise Linuxbaseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/daggpgcheck=0enabled=1 |
yum -y install ffmpeg |
1、安装所需软件
yum install -y automake autoconf libtool gcc gcc-c++
2、安装第三方更新源
rpm -ivh http://apt.sw.be/redhat/el6/en/i386/rpmforge/RPMS/rpmforge-release-0.5.3-1.el6.rf.i686.rpm
3、安装ffmpeg
yum install ffmpeg ffmpeg-devel
会自动安装众多解码器,ffmpeg版本为0.6.5-1.el6.rf。看了下yum安装的解码器版本还不是很旧,但是ffmpeg版本较老。
4、测试一下
将一个.avi视屏转为.flv格式
ffmpeg -i Destination.avi -y -ab 56 -ar 22050 -r 15 -sameq test2.flv
转换前后两个文件的格式比较:
