[Ffmpeg-devel] dct-test infastructure

[Marc Hoffman]

I'm curious if there is something else I should be using as dct test  
infastructure this code doesn't seem to compile well on a MAC.  Well  
I do rip the whole thing out make a few dummies and it well has  
pretty large signal errors which doesn't seem right to me.  I will  
try it on an X86 machine later when I get access to one.

Does anyone have any good ideas here for how to proceed?  What does  
the group accept for error how does it test this in new architectures?
