"I am capturing NTSC video data from video port interface on AM1808. I am using unmodified drivers from Linux PSP and vpif_test_mmap_loopback example application. The captured frames are 720*480 pixels. I see that the last line in each frame has HEX 80 80 80 80 pattern which shows as a white line at the bottom of the screen screen. "
How can I get rid of this white line?
