[FFmpeg-devel] [PATCH 1/5] libavcodec: Implementation of 32 bit fixed point FFT

I worked a bit on the Rockbox FFT. We took the FFMPEG one as-is and adapted it for use on simple ARM devices (our goal was ARM7/ARM9). Perhaps on newer, more deeply pipelined devices it is not as efficient.
One question, how do I interpret the RMSE values? Is it value/2^31? So 48.18 would be ~ 25 bits accuracy? Or am I misunderstanding?
