[FFmpeg-user] DCT coefficients dequantification

Hi everyone,

I'm trying to recover DCT coefficients while decoding h264 using FFMPEG
libavcodec. It seems that in ff_h264_mb_decode_cabac, DCT coefficients are
re-ordered (zig zag ordering).
However i can't find where dequantification is made in order to find the
right DCT elements.
Can anybody help?

Thanks in advance,
Vero
