  Hi,
  You can use any YUV file viewer which can be downloaded from net. Infact
the source code for those viewers is also avaliable. About the format, it is
as follows.
  Lets say the picture resolution is  W x H (Width x Height) and 420 format,
  first W*H bytes represent the luma part, next (W * H)/4  represent Cr and
next (W * H)/4  represent Cb.
  Regards,
  Satish
