I use decoder.c in xvidcore-1.1.0-beta2. I want to modify the dc coeff of each macroblock in each frame while decoding. But i don't want to re-encode it. Because the dct or quantization operation will cause tiny changes to dc coeffs. I try to refill the coeffs into bitstream but it seems very complicated to do it. Somebody give me some suggestion? Thanks :D
