updated as below:

Capture:
  Mode                : Direct fetch
  VGA bpp mode        : 32
  Signal              : lock
  Width               : 1920
  Height              : 1080
  FRC                 : 0

Compression:
  Format              : JPEG
  Subsampling         : 444
  Quality             : 4
  HQ Mode             : N/A
  HQ Quality          : 0
  Mode                : N/A

Performance:
  Frame#              : 4
  Frame Duration(ms)  :
    Now               : 22
    Min               : 21
    Max               : 22
  FPS                 : 47
