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".

DESCRIPTION
minresolution A list of <Integer> 0/7 Represent supported minimum
resolution of each stream in current
video mode.
* The element number is defined as
"capability_nmediastream".
* We support this parameter when the
version number (httpversion) is equal or
greater than 0304b.
maxframerate A list of <Positive
Integer>
0/7 Indicates frame rate that the video
source outputs in this video mode.
* One to one mapping to the resolution
in "resolution".
* The element number is defined as
"nresolution" in this group.
* This parameter records the frame rate
when
"videoin_c<0~(n-1)>_cmosfreq"=60 or
"videoin_c<0~(n-1)>_modulation"=ntsc
maxfps_mjpeg A list of <Positive
Integer> and "-"
0/7 Maximum fps which the device can
encoded with MJPEG on resolutions in
this video mode.
"-" means not support.
* One to one mapping to the resolution
in "resolution".
* The element number is defined as
"nresolution" in this group.
* This parameter records the frame rate
when
"videoin_c<0~(n-1)>_cmosfreq"=60 or
"videoin_c<0~(n-1)>_modulation"=ntsc
* Only available when 'mjpeg' is listed in
"capability_videoin_codec".
