I did install ffmpeg with winff, unsuccessfully when I try converting avi to x264, it says I don't have it. When I try to convert mp4 to Xvid I get unknown encoder 'libxvid'. It's like nothing really works except avi Msi compatible using winff.

Can anyone help?

First, remove the actual ffmpeg installation yum remove ffmpeg ffmpeg-devel, you will have to install the DAG RPM repositories which contains huge amount of rpm packages. It’s very easy. Just install the latest rpmforge-release package for your distribution and architecture.

This will automatically install the configuration and GPG keys that are for safely installing RPMforge packages.

nano -w /etc/yum.repos.d/dag.repo

Insert :-



[dag]

name=Dag RPM Repository for Red Hat Enterprise Linux

baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag

gpgcheck=1

enabled=1

Then save the repo file also you can update RPM through rpmforge :-

rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS//rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

yum update

Installing FFMPEG.:-

yum install ffmpeg ffmpeg-devel

If Seems there is some lib problems along the way so in /etc/ld.so.conf add

/usr/local/lib

also check /etc/ld.so.conf.d and make sure there are no .conf files that may be loading other files.

then

ldconfig -v

I hope it helps...
