Hi,

Hi,

I was testing with a prefilter mode that tries to reduce the encoding of
pure noise in otherwise non-changing material blocks. It's similar to the "zero frames" discussed earlier, but it works on 8x8 block level and uses DCT to detect identical blocks.


My first version is the attached modified encoder.c



Sorry, remove the line 1206:


fprintf(stderr,"cbp=%x\n",cbp);


sorry, can' test it:

D:\data\PROGTEMP\XviD-18082002\xvid\xvidcore\src\encoder.c(1204): error #165: too few arguments in function call
cbp = MBTransQuantInterBVOP(&pEnc->mbParam, pEnc->current, pMB, dct_codes, qcoeff);


...or do i have to test with bframes activated?

best regards,
Dirk
