If set to 0, flicker avoidance is automatic.
If set to 1, 50hz AC power frequency flicker avoidance (Europe/Asia).
If set to 2, 60hz AC power frequency flicker avoidance (North America).
video.camera.frameRate
Set target frame rate (frames per second). Values indicate a fixed frame rate, from 5 (least smooth) to 30 (most
smooth).
Note: If video.camera.frameRate is set to a decimal number, the value 25 is used.
video.camera.saturation
Set saturation level. The value range is from 0 (Lowest) to 6 (Highest).
video.camera.sharpness
Set sharpness level. The value range is from 0 (Lowest) to 6 (Highest).

advised to do so.
Video Profile Parameters
Parameter
video.profile.H261.annexD
Enable or disable Annex D when negotiating video calls.
video.profile.H261.CifMpi
Specify the frame rate divider that the system uses when negotiating CIF resolution for a video call. You can enter a
value between 0-4. To disable, enter '0'. The default frame rate divider is '1'.
video.profile.H261.jitterBufferMax
The largest jitter buffer depth to be supported (in milliseconds). Jitter above this size always causes lost packets. This
parameter should be set to the smallest possible value that support the expected network jitter.
