[libav-devel] [RFC] Cineform HD questions

This patch is the first attempt at getting a working Cineform HD decoder into avcodec
It supports YUV422P10 files which are the majority of files in the wild
There are some files not supported such as those from film scanners and some older files which do something unusual with chroma and the transform.
Also files which are cut awkwardly will infinite loop in the coefficient decoding because of a lack of escape symbol.

The big question is how to organise the coefficients - at the moment all the buffers are hardcoded.
If anyone has any suggestions about the best way to do this, that would be appreciated.
