DESCRIPTION
eptz
0, <positive integer> 0/7
Indicate this mode whether support eptz.
For "nvideoin" = 1, the definition is as following:
A 32-bits integer, each bit can be set separately as
follows:
Bit 0 => 1st stream supports ePTZ or not.
Bit 1 => 2nd stream supports ePTZ or not, and so on.
For nvideoin >= 2, the definition is different:
First all 32 bits are divided into groups for channel.
Ex:
nvideoin = 2, bit 0~15 are the 1st group for 1st channel,
bit 16~31 are the 2nd group for 2nd channel.
nvideoin = 3, bit 0~9 are the 1st group for 1st channel,
bit 10~19 are the 2nd group for 2nd channel, bit 20~31
are the 3rd group for 3rd channel.
Then, the 1st bit of the group indicates 1st stream of a
channel support ePTZ or not. The 2nd bit of the group
indicates 2nd stream of a channel support ePTZ or not,
and so on.
* We support this parameter when the version number
(httpversion) is equal or greater than 0304b.
wdrpro
0, 1, 2
0/7
Indicate this mode whether support WDR pro.
0: Non-support WDR Pro
1: Support WDR Pro
2: Support WDR Pro and WDR Pro II
* 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.

DESCRIPTION
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.
resolution
A list of <WxH>
0/7
Resolution options in this video mode.
The last one is the maximum resolution
in this video mode.
* The element number is defined as
"nresolution" in this group.
maxresolution
A list of <Integer>
0/7
Represent supported maximum
resolution of each stream in current
video mode.
* The element number is defined as
"capability_nmediastream".
