[FFmpeg-devel] AVFrame.dct_coeff is null...

Hi everyone,
I would like to get the DCT coefficients from a decoded MPEG stream for
filtering motion vectors out based on the AC coefficient (for estimating the
camera motion based on a video).
Problem is: dct_coeff is always NULL :-(

Can I get them somewhere else?
