[Mp4-tech] How do I calculate the information of motion vector and mb_type in JM code ?

[Lee Daniel]

All Experts : 
        I have a question about : how can I calculate the statistic 
information about the coded file by JM ?
       such like, the motion vectors ,  SAD values , or mb_type mode 
....etc in the coded *.264 file.
       Is it possbile for me to know the relationship between the motion 
vectors and coded block size ? 
      Are there any tools doing such works ? Should I  write them down step 
by step by pressing F10 ?
Thanks All .  X'mas .
Daniel.
