* We support this parameter when the version
number (httpversion) is equal or greater than
0304b.
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 The 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.
binning 0, 1, 3 0/7 Indicate binning is used or not in this video
mode.
0: No binning
1: 2x2 binning
3: 3x3 binning
* Binning is a technology to increase light
sensitivity by combining multiple pixels to one.
The drawback is reduced resolution. We design
this parameter to disclose this information.
nresolution <positive integer> 0/7 How many resolution options in this video mode.
