i tested sample code video_in_out, when i used image viewer to see my image, i find a lot of blanking, just like following:

 

blanking

blanking                        img1

   .

   .

   .

blanking        blanking     blanking     blanking

   .

   .                               img2

   .

blanking

 

img1 is simillar to img2, in this condition is it normal?

 

1.how can i filter this blanking? (PS : i want to get img with size 858*525 or other size)

2.when i reset PIXEL_PER_LINE and LINES_PER_FRAME i can't get img, why? default setting PIXEL_PER_LINE=858 LINES_PER_FRAME=525,

is it relative with itu656?

3.in PPI0_CONTROL, if i don't want to get image by itu656, how can i set PPI0_CONTROL bit

 

i use following conf to see image viewer

 

StartAddres> sframe0
width.  858
heigh   525
Stride 1
