DESCRIPTION
rotation <boolean> 0/7 Indicate this mode whether support video
rotation
effectivepixel <WxH> 0/7 The visible area of full scene in this video mode.
The unit is pixel in source.
* If
"effectivepixel"<"capability_videoin_c<0~(n-1)
>_maxsize", then the visible area is located at
the center of full scene.
outputsize <WxH> 0/7
T
he output size of source, equal to the captured
size by device, in this video mode. The unit is
pixel.
This value is used as a basic coordinate system
for many features, like ePTZ, privacy mask,
motion, etc.
* Source (most for image sensor) may perform
scale or binning, etc on image data, and output
data with smaller size. This parameter is
designed to represent this.
