How to install the transcoding tools on Redhat / CentOS 5

 

This HowTo describes the Transcoding Tools installation under RedHat / CentOS 5.9.

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 describes 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).

 

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 php-process 

 

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 xvidcore-devel 

 

We install x264

wget ftp://ftp.videolan.org/pub/videolan/x264/snapshots/last_stable_x264.tar.bz2
tar xvjf last_stable_x264.tar.bz2
cd x264-snapshot-XXXXXXXX-XXXX-stable/
./configure --enable-shared --enable-pic
make && make install
cd ..

 

We install libtheora

wget http://downloads.xiph.org/releases/theora/libtheora-1.1.1.tar.bz2
tar xvjf libtheora-1.1.1.tar.bz2
cd libtheora-1.1.1/
./configure
make
make install
cd ..

 

 

We install libvpx:

wget http://webm.googlecode.com/files/libvpx-v0.9.7-p1.tar.bz2
tar xvjf libvpx-v0.9.7-p1.tar.bz2
cd libvpx-v0.9.7-p1
./configure --enable-shared
make
make install
cd ..

 

... and FFmpeg and FFprobe:

wget http://ffmpeg.org/releases/ffmpeg-0.7.12.tar.bz2
tar xvjf ffmpeg-0.7.12.tar.bz2
cd ffmpeg-0.7.12/
./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 --enable-x11grab --extra-cflags="-I/usr/local/include" --extra-ldflags="-L/usr/local/lib" 
make
make install

 

 

IMPORTANT:

- execute ldconfig

 

# ldconfig

 

- download the presets-package here and copy the presets to /usr/local/share/ffmpeg

- tell VIMP the path to FFmpeg in the backend (administration -> configuration -> transcoder -> ffmpeg: /usr/local/bin/ffmpeg

- check if qt-faststart is installed (which qt-faststart). If not, you can download it here.

 

 

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
