How to install Transcoding tools CentOS 6.4

This HowTo describes how to install transcoding tools CentOS 6.4.

The ffmpeg packages for RedHat-based distributions (RHEL, CentOS) don´t support transcoding to all HTML5 formats. In detail there are problems with transcoding to m4v.

This tutorial explains how to compile ffmpeg in order to support all HTML5 formats.

In this tutorial we assume that you´re in /usr/src (cd /usr/src).


First, we install the rpmforge and epel repository.

Install rpmforge repository
Install epel repository

Now let’s install some basic packages. Existing packages will be updated or ignored:

yum install gcc make automake bzip2 unzip patch subversion libjpeg-devel yasm

If you have already installed the packages ffmpeg and x264, remove them:

yum remove ffmpeg x264

Installing the win codecs of the MPlayer vendor:

NOTE: on 32 bit systems install the codecs as follows:

tar xvjf essential-20071007.tar.bz2
mkdir /usr/local/lib/codecs
cp -Rvp essential-20071007/* /usr/local/lib/codecs/

NOTE: on 64 bit systems install the codecs as follows:

tar xvjf essential-amd64-20071007.tar.bz2
mkdir /usr/local/lib/codecs
cp -Rvp essential-amd64-20071007/* /usr/local/lib/codecs/

Next, on both systems we have to extend the search path in /etc/

joe /etc/

… and check, if the following lines exist within the file. If not, please add:


We install some codecs:

yum install faac-devel  lame-devel amrnb-devel opencore-amr-devel amrwb-devel  libvorbis-devel libtheora-devel xvidcore-devel 

We install x264:

tar xvjf last_stable_x264.tar.bz2
cd x264-snapshot-XXXXXXXX-XXXX-stable/
./configure --enable-shared --enable-pic
make && make install
cd ..

We install libvpx:

tar xvjf libvpx-v1.2.0.tar.bz2
cd libvpx-v1.2.0
./configure --enable-shared --enable-pic
make install
cd ..

… and ffmpeg:

tar xvjf ffmpeg-2.0.1.tar.bz2
cd ffmpeg-2.0.1/
./configure --enable-gpl --enable-version3 --enable-shared --enable-nonfree --enable-postproc --enable-libfaac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid
make install


– execute ldconfig

# ldconfig

Finally we install MPlayer, mencoder and flvtool2:

yum install mplayer mencoder flvtool2
