With OCaml you can't use features like SIMD instructions of CPUs, and  
will do many bound checking, so it will be slower.
I'm a bit sceptical that ocaml may be as good as C for pure signal  
processing.

Writing a mpeg2 decoder won't take less than a week !!! (except  
perhaps if you've already spent time on a mpeg2 decoder)

If you have to write something, a ocaml wrapper for ffmpeg may be a  
good start.
