ABOUT
-----

libmimic is an open source video encoding/decoding library for Mimic V2.x-
encoded content (fourCC: ML20), which is the encoding used by MSN Messenger
for webcam conversations.

It was written because there was no third-party MSN-client that supported
this feature due to this proprietary/unknown codec involved. I didn't like
this lack of interoperability, so I decided to do something about it. After
studying the official MSN-client a little closer, it became clear that the
codec involved was statically linked into the executable, so there was no
easy way to use the codec code through Wine. So for fun, and challenge, I
reverse-engineered the original implementation by studying the massive
amount of assembly code involved, and after a lot of hard work I ended
up with this implementation in C.

It should be noted that reverse-engineering for interoperability is 100%
legal here in Norway (and in most European countries).


THANKS

Special thanks to Rob Taylor and the rest of the Farsight-team for all
the feedback and inspiration during development, you guys rock! :-)
