Thank you once more for the prompt reply! The reason why all these
questions is because i'm trying to print out the DCT coefficient Table for
I've tried by printing out the block[j] elements in
decode_cabac_residual_internal (STORE_BLOCK), and by printing out h->mb in
decode_slice after decode_mb_cabac is called.
Is any of these options the right one in order to print out the dequant DCT
coefficients? Maybe I'm not hitting with the right place or the right line
Thank you once again, I appreciate your help.
