Instance Property

videoMinFrameDuration

The minimum time interval between which the receiver should output consecutive video frames.

Declaration

@property(nonatomic) CMTime videoMinFrameDuration;

Discussion

The value of this property specifies the minimum duration of each video frame output by the connection, placing a lower bound on the amount of time that should separate consecutive frames. The value is equivalent to the reciprocal of the maximum frame rate.

A value of kCMTimeZero or kCMTimeInvalid indicates an unlimited maximum frame rate.

The default value is kCMTimeInvalid.

You can only set this value if supportsVideoMinFrameDuration is YES.
