Good idea, however it can't work as expected after tried.  On the other hand,
even if it works, it's hacker mode only since we can't get any help
information by "-h".


Below is the test result:
./ffmpeg -pass 1 -s 352x288 -i /home/lmwang/download/test_sequence/bus_cif.yuv
- -partitions -1+parti4x4 -vcodec h264 /tmp/1.h264

#options: 352x288 fps=25/1 cabac=0 ref=1 deblock=0:0:0 analyse=0x1:0x1 me=dia
