All USB Pixelink cameras.
Description
This read-only feature allows the user to query the camera to see what frame rate the camera will use while streaming image data. This value is generally the same as FEATURE_FRAME_RATE, but will be of a lesser value if the user is controlling the frame rate (IE, FEATURE_FRAME_RATE is enabled) and one of the following conditions is true:
- The current camera exposure is preventing the camera from achieving the frame rate requested by FEATURE_FRAME_RATE or
- FEATURE_BANDWIDTH_LIMIT is enabled, and its current value is preventing the camera from achieving the frame rate requested by FEATURE_FRAME_RATE
