Hi Gwern,

I just checked H.263 and it looks like it does not require patent licensing

write H.263 in Haskell and release freely without patent licensing issues.
So writing H.263 in Haskell could be a good GSoC project. One mentioned
that GHC produce slow code, well H.263 could be a good test case to improve
GHC optimization over time. In The Computer Language Benchmarks Game,
Haskell has some catching up to do. :)
It does sound like a reasonably discrete task, and it sounds like you
have a use for it; but I wonder if it's doable in a single summer?
I have no idea, I have not dig deeper into H.263 C source code but I guess
it should be quite trivial as it is a black box with video frame input and
output with several parameters for encoding and just frame in/out for
decoding.
That could be a seed to create Haskell library of video/audio codecs.
One mentioned that C based ffmpeg library is buggy with memory leaks left
and center (and probably right too :) Ouch!
