How to install the transcoding tools on Redhat / CentOS 6

This HowTo describes how to install the transcoding tools under RedHat / 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 zlib-devel libjpeg-devel yasm  

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

yum remove ffmpeg x264

Next, on both systems we have to extend the search path in /etc/ld.so.conf

joe /etc/ld.so.conf      

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

/usr/lib  
/usr/local/lib

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:

git clone http://git.videolan.org/git/x264.git
cd x264
./configure --enable-shared --enable-pic
make && make install
cd ..

We install libvpx:

git clone http://git.videolan.org/git/x264.git
cd x264
./configure --enable-shared --enable-pic
make && make install
cd ..

... and FFmpeg and FFprobe:

wget http://ffmpeg.org/releases/ffmpeg-2.0.1.tar.bz2
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
make install

IMPORTANT:

- execute ldconfig

# ldconfig

We install exiftool (VIMP 3.2.0 and greater):

yum install perl-Image-ExifTool

Up to VIMP <= 3.1.9 you need MPlayer/mencoder:

yum install mplayer mencoder
