Setting up ffmpeg 2.4.0 for eclipse in ubuntu 12.04

First of all make sure your OS has no previous installation content of ffmpeg installed in ubuntu.
In case you have a previous installation of ffmpeg, then delete those folders and type
sudo apt-get remove ffmpeg x264
sudo apt-get autoremove
in terminal to remove any previous ffmpeg installation content.
Then start from here
sudo apt-get update
sudo apt-get upgrade

sudo apt-get install make automake g++ bzip2 python unzip patch subversion ruby build-essential git-core checkinstall yasm texi2html libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libsdl1.2-dev libtheora-dev libvdpau-dev libvorbis-dev libvpx-dev libx11-dev libxfixes-dev libxvidcore-dev zlib1g-dev
in case it gives error of ERROR: libopencore_amrnb not found
type
sudo apt-get install libopencore-amrnb
then install x264
sudo wget http://webm.googlecode.com/files/libvpx-v0.9.7-p1.tar.bz2
sudo tar xvjf libvpx-v0.9.7-p1.tar.bz2
cd libvpx-v0.9.7-p1
sudo ./configure –enable-shared –prefix=/usr/local
sudo make
sudo make install
cd ..
in case you get an error “Found yasm 1.1.0.2352
Minimum version is yasm-1.2.0
If you really want to compile without asm, configure with –disable-asm.”
it means your yasm version is too low, so you should install a latest version of yasm
git clone git://github.com/yasm/yasm.git
cd yasm
./autogen.sh
./configure
make
make install

and then continue with installing x264
install libvpx
sudo wget http://webm.googlecode.com/files/libvpx-v0.9.7-p1.tar.bz2
sudo tar xvjf libvpx-v0.9.7-p1.tar.bz2
cd libvpx-v0.9.7-p1
sudo ./configure –enable-shared –prefix=/usr/local
sudo make
sudo make install
cd ..
After this check if /etc/ld.so.conf contains the lines /usr/lib and /usr/local/lib. if not then add them and save it
to check that do
sudo gedit /etc/ld.so.conf
or
sudo nano /etc/ld.so.conf

then run
sudo ldconfig
Now you can install ffmpeg by doing

sudo wget http://ffmpeg.org/releases/ffmpeg-0.8.10.tar.bz2
sudo tar xvjf ffmpeg-0.8.10.tar.bz2
cd ffmpeg-0.8.10
./configure –enable-gpl –enable-version3 –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-shared –prefix=/usr/local
sudo make
sudo make install
cd ..
sudo ldconfig

In your eclipse project you can inculde the headers this way
#include #include
In eclipse you can add the ffmpeg libraries to your project: avutil, avformat, avcodec, m, z … by going to project->properties->C/C++->Build->Settings->GCC C++-> Linker->Libraries
