[Deinterlace-discuss] Overscan - how many pixels at left and right ?

[Laurent G. <lau...@cl...>]

Hi

I need your help. I still have a problem with the overscan when calculating
analysis zones for my calibration code.
What I understand is that overscan is a sort of zoom in the source rectangle.
When an overscan of 10 is defined, 10 lines at top and 10 lines at bottom
from the original buffer are not taken into account.
My question : how many pixels not taken into account at left and right ?
I suppose this number is dependent on the pixel width and maybe even the
aspect ratio too ?
I believed it was always 10 pixels but when I verified drawing a line in the
buffer at the supposed position, I saw that it is not correct and that it seems
to be dependant on piwel width.
