They could easily be hardcoded in, however they could then be wrong as asumptions are being made which might not be true, and are probably not verifiable. For example if you are recoding an SD YUV file, you might resonably assume that it is 601, but it might not be, and unless the source file explicitly defines it as such, and you carry that information forward you are just guessing, ffmpeg has no way of knowing the matrix used to generate the values. Therfore I think the only sane approach would be to have them as user settable flags which would take more careful thinking about... -- Tim.
