Repost: FFMpeg Installation on CentOS and RedHat

Install FFmpeg on CentOS or RedHat EL 6.x

The following install steps have been proven to work on RedHat Enterprise Linux 6.2. You can check which version you are running with

# cat /etc/redhat-release

Additionally, we assume that you are connected and registered with the Red Hat network and/or updated the system with the latest updates from the repositories.

Follow this guide step by step!

Install the additional repo

# rpm -Uhv http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

Update repository

# yum -y update

Install all necessary packages

# yum install SDL-devel a52dec a52dec-devel alsa-lib-devel faac faac-devel faad2 faad2-devel # yum install freetype-devel giflib gsm gsm-devel imlib2 imlib2-devel lame lame-devel libICE-devel libSM-devel libX11-devel # yum install libXau-devel libXdmcp-devel libXext-devel libXrandr-devel libXrender-devel libXt-devel # yum install id3tag-devel libogg libvorbis vorbis-tools mesa-libGL-devel mesa-libGLU-devel xorg-x11-proto-devel xvidcore xvidcore-devel zlib-devel # yum install amrnb-devel amrwb-devel # yum install libtheora theora-tools # yum install glibc gcc gcc-c++ autoconf automake libtool # yum install ncurses-devel # yum install libdc1394 libdc1394-devel # yum install yasm nasm # yum install libvpx* # yum install git-core # yum install opencore-amr-devel

Install Libvorbis

# wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.3.tar.gz # tar xzvf libvorbis-1.3.3.tar.gz # cd libvorbis-1.3.3 # ./configure # make # make install

Install Libtheora

# wget http://downloads.xiph.org/releases/theora/libtheora-1.1.1.tar.gz # tar xzvf libtheora-1.1.1.tar.gz # cd libtheora-1.1.1 # ./configure # make # make install

# git clone http://git.chromium.org/webm/libvpx.git # cd libvpx # ./configure --enable-shared --extra-cflags=-fPIC # make # make install

Install Aacenc

# wget http://downloads.sourceforge.net/opencore-amr/vo-aacenc-0.1.2.tar.gz # tar xzvf vo-aacenc-0.1.2.tar.gz # cd vo-aacenc-0.1.2 # ./configure --enable-shared # make # make install

Install X264

# git clone git://git.videolan.org/x264.git # cd x264 # ./configure --enable-shared --extra-cflags=-fPIC --extra-asflags=-D__PIC__ # make # make install

Note: (Sometimes the network might be down. Then you can also grab it via wget at ftp://ftp.videolan.org/pub/videolan/x264/snapshots/last_stable_x264.tar.bz2)

Configure Libraries

# export LD_LIBRARY_PATH=/usr/local/lib/ # echo /usr/local/lib > /etc/ld.so.conf.d/custom-libs.conf # ldconfig

Compile FFmpeg (the configure options have to be on one line)

# git clone git://source.ffmpeg.org/ffmpeg.git # cd ffmpeg # git checkout n1.2 # ./configure --enable-version3 --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvpx --enable-libfaac --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libvo-aacenc --enable-libxvid --disable-ffplay --enable-shared --enable-gpl --enable-postproc --enable-nonfree --enable-avfilter --enable-pthreads --extra-cflags=-fPIC # make # make install

(The –arch=x86_64 option should only be used if you are on a 64Bit System!)

You can also use their Github repository at https://github.com/FFmpeg/FFmpeg.git.

That’s it. This should give you a full functional FFMpeg installation for Razuna. Test it now with;

# ffmpeg

This should give you the following back (yours might vary a bit);

Repost: ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file

The “loading shared libraries” error message is received when ffmpeg is not able to locate the file libavdevice.so.52. This happens when either the file is missing from the server OR ffmpeg is not looking at the path the file is in. You see the following error while executing the ‘ffmpeg’ command:

[root@server ~]# ffmpeg
ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory

Solution:
Search the file libavdevice.so.52 on the server using the ‘find’ command

# find / -name libavdevice.so.52

You need to add the path to the directory the file is in, in the ‘ld.so.conf’ file. If for example the file is located under “/usr/local/lib” directory, execute

# vi /etc/ld.so.conf

and add the following at the bottom of the file

/usr/local/lib

Save the file and for the new changes to take effect, execute

# ldconfig
