Regarding the video display on LCD screen of Intel PxA27x DVK board

[satish babu]

Hi all,

     We had ported the H.264 video decoder on to Intel PxA27x DVK
board.we had converted the YUV output of h.264 decoder into RGB(565)
format,done resize from 24 bit to 16 bit format and given the final
output to LCD display of Intel PxA27x DVK board.

     But instead of getting one video on Intel PxA27x DVK LCD
display(as shown in below fig :1) we are getting two videos(same video
repeated at same time) (as shown in below fig:2):
