Video manipulation using ffmpeg library

I need a p开发者_JS百科roper documentation and explanation of the ffmpeg library files that we can use to do programming so as to make a video editor that is capable of adding effects in video and merging 2 different video files.I want to make the editor for android,although i got the android specific ffmpeg files from http://bambuser.com/opensource but i am unable to utilize them for my purpose. I tried a simple c program in devC++ using the header files like avcodec.h avformat.h given in ffmpeg but getting linker error for function like av_register_all,av_open_input_file.
