ffmpeg for Ubuntu

I looked for ffmpeg to run on my Ubuntu VirtualBox VM. However, it turned out that there is a competitor (fork of ffmpeg) which is typically used with Ubuntu: libav.

So the install was very easy:

sudo apt-get update
sudo apt-get install libav-tools

and avprobe prints info about the video file -

How To Install ffmpeg on CentOs 6.x (6.3)

I installed ffmpeg on a dedicated CenOs 6.3 server. The installation mostly follows the instrcutions given by the eFFMPEG group here, but there are few important twists if you want to get it done.

1. Login as root

2.Pre-set:
# remove older installations

yum erase ffmpeg x264 x264-devel

#verify you get all teh tools:

yum install gcc git make nasm pkgconfig wget

#create a working folder

mkdir ~/ffmpeg-source

3. Installations

#install yam 

cd ~/ffmpeg-source
wget http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gz
tar xzvf yasm-1.2.0.tar.gz
cd yasm-1.2.0
./configure
make
make install

#install x264

cd ~/ffmpeg-source
git clone git://git.videolan.org/x264
cd x264
./configure --enable-static
make
make install

#install mp3 encoder

cd ~/ffmpeg-source
wget http://downloads.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gz
tar xzvf lame-3.99.5.tar.gz
cd lame-3.99.5
./configure --disable-shared --enable-nasm
make
make install 

#install libogg

cd ~/ffmpeg-source
wget http://downloads.xiph.org/releases/ogg/libogg-1.3.0.tar.gz
tar xzvf libogg-1.3.0.tar.gz
cd libogg-1.3.0
./configure --disable-shared
make
make install

#install libvorbis

cd ~/ffmpeg-source
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 --disable-shared
make
make install 

#install libvpx

cd ~/ffmpeg-source
git clone http://git.chromium.org/webm/libvpx.git
cd libvpx
./configure
make
make install

#install zlib

cd ~/ffmpeg-source
wget http://zlib.net/zlib-1.2.7.tar.gz
tar xzvf zlib-1.2.7.tar.gz
cd zlib-1.2.7
./configure
make
make install 

#FFMPEG did not want to work well in /tmp
mkdir ~/tmp
export TMPDIR=~/tmp

#you might also need to add to PATH /usr/lib
export PATH=$PATH:/usr/lib

#and probably add (I did it, but not sure it is a must)
export LD_LIBRARY_PATH=/usr/local/lib

#now install ffmeg from GIT repository

cd ~/ffmpeg-source
git clone git://source.ffmpeg.org/ffmpeg
cd ffmpeg
./configure --enable-gpl --enable-libmp3lame --enable-libvorbis --enable-libvpx --enable-libx264
make
make install

#this should work now! type 'ffmpeg' to try
