Creating Audio and Video Codecs

[Extra]

Where can I learn how to create my own video codec? (or hack someone else's)
What software will I need?

Yes I realize there are already enough of them

[khp]

Dowload the source code for an open source codec.

Huffyuv is open source, you should be able to find that, easy.

Of course you will need a complier, to compile the source code, huffyuv and most other codecs are build using MSVC, so you will need that.
