NOTICE: This tool only can be used for TESTING !!!
To see more usage, please enter: ./vi_chn_dump -h

usage: ./vi_chn_dump [vi_pipe] [vi_chn] [frame_cnt] [dump_frame_pos]
1)vi_pipe:
vi pipe id
2)vi_chn:
vi chn id
3)frame_cnt:
the count of frame to be dump
4)dump_frame_pos:
the position of frame to be dump(only vi_chn 0 support dump raw after wdr
0: dump frame after all isp module. default
1: dump raw after wdr module
*)example:
e.g : ./vi_chn_dump 0 0 1 1
e.g : ./vi_chn_dump 1 2 2 0
