Enable/Disable video support on IQA2xx cameras and is read only
for IQ73xx series cameras. Default is enabled.
Video bitrate
1.17.2.2
Video bit rate in Kbps of the primary H.264 stream. The default
value depends on the stream being requested. For CBR connections
this is the CBR rate. For VBR connections the value specified is the
average bit rate of what he camera will deliver.

VBR. Default is VBR.
Video preference
1.17.2.8
Specifies if the codec will drop quality to maintain frame rate
(FRAMERATE) or drop frame rate to maintain quality (QUALITY).
These options are primarily applicable if configured for a constant
bit rate stream. Default is FRAMERATE.
