Download Eclipse
Download “Eclipse IDE for C/C++ Developers” all in one installation from http://www.eclipse.org/downloads/
Uncompress and run Eclipse
After uncompressing (usually with "tar xzf eclipse.<version info here>.tar.gz"), you can simply enter the eclipse directory (with "cd eclipse") and run the Eclipse (usually using "./eclipse"). After you start the Eclipse for the first time, it will ask you for the "workspace" directory. This directory will contain your future projects in subdirectories.
【附】运行eclipse需要安装JRE(安装方法见博文：ubuntu下安装最新 版jre 7)
Create new C++ project using existing FFmpeg's source code
In the Eclipse, go to main menu option "File - New - Project", then choose "C/C++" and then "Makefile Project with Existing Code" and navigate to the FFmpeg's source code directory“ffmpeg-1.1.3”.
在Import Existing Code对话框中的Toolchain for Indexer Settings中选Linux GCC
Compile the source code
First of all, make sure you have c++, g++, make and other build tools installed. If you are using debian/ubuntu, you can type "apt-get install build-essential". Before you compile the source code for the first time, you'll have to go to your ffmpeg root directory ("ffmpeg-1.1.3") and type "./configure". After it finishes, go back to Eclipse and use the main menu option "Project - Build All".
我用的选项：
./configure --enable-gpl --disable-optimizations --disable-ffplay --disable-asm –prefix=/usr
可以加—enable-shared
如果想在windows下开发，有个网站有：
Dev packages provide the headers and .lib/.dll.a files required to use the .dll files in other programs.

右键点击ffmpeg_g选debug as->Local c/c++ Application
加调试初始参数：
右键点击ffmpeg_g选debug as-> Debug Configuration
