  As i understand, my camera has a image processor inside it. what i
want to say is it is
  not a plain raw sensor.

  For every pixel clock a pixel is fetched from the device and is
placed in memory
  Once a entire frame is captured. it is returned to the application.

   i can write this data into LCD or a file to be viewed by a YUV/RGB
viewer like YUVTOOLS.

  This is same for both RGB and YUV data.


  my only concern is i should fill proper values to v4l2_pix_format structure.

  Thank you.

vedan
