hi all:
I am using tvp-5150 for encoder and connect to DM365 C[0-7]. Camera is PAL.
test code is from SpectrulDigital, I have changed some appropriately. here is the code:
static void vpfe_init( Uint32 ntsc_pal_mode )
{
Uint32 width;
Uint32 height;
if ( ntsc_pal_mode == NTSC )
{
width = 720;
height = 480;
}
else
{
width = 720;
height = 576; //change to 576
}

vpbe_init( LOOPBACK, PAL, COMPOSITE_OUT );

}
But I find no COLOR in some monitor (both ColorBar and Loopback), but some monitor has color.
And when testing loop-back ,I can see some blink like water wave from the video, can I program the register to solve this problem?
Thanks.
