Thanks for doing this.  You got to it first before I could recommend it to you!

One thing I would suggest is to take this code out of FFTFrameFFMPEG and move it to a place where other FFTFrame implementations could potentially use it (or other code needing complex multiply).  Maybe it makes sense to make a function for this in VectorMath?  In FFTFrameMac.cpp there's a call to a vecLib function called vDSP_zvmul(), so zvmul()??
