Re: v4l2_pix_format doubts

I think you got confused by RGB and YUV.

The device is capable of giving RGB and YUV data. This is done by a
setting in the sensor register.

Once i set the value, 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.
>From the application   i can write this data into LCD or a file to be
viewed by a YUV/RGB
viewer like YUVTOOLS.


Now, i know what i should set the pix->pixelformat, but what about
other members of the
v4l2_pix_format structure.
