[Mp4-tech] question regarding prediction error

[Fabrizio]

Dear Nitin,
I think you try to find prediction error in the "LumaResidualCoding8x8" function. In particular you have to look  img->m7[j][i], in wich I think is stored the difference between original image and predicted for each pixel.
Best regards,
Fabrizio
