I'm new to Linux, I need to work on Linux. I have ported Linux to AT91SAM9261-EK board. Now i need to work on Codecs. I just know the definition of codec from wikipedia, Now i need add my own codec to the board.

I want to know,

Where codec will be preset in 1)File System, 2)Kernel or 3)Player
And how to add codec while building entire source, please tell me the steps i need follow.
And also how to remove the codec.
