[x264-devel] [libx264] About per-macroblock encoding

[Wei Miao]

Hello:

My name is Wei and I am now a master student at University of Michigan. I
am now using libx264 under Linux to do some projects. In one of these
projects, I need to encode a frame into 2different QP : some specified
macroblock to a higher QP, the other to a lower one. I tried to modified
the file encoder/macroblock.c but it seems to be unstable and it will screw
up the image. My question is: is there any way to specified QP for each
macroblock? If i need to modify the code in x264, which part of code should
I try?

Thank you very much.
