Instance Property

videoMaxFrameDuration

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

Declaration

@property(nonatomic) CMTime videoMaxFrameDuration;

Discussion

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

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

The default value is kCMTimeInvalid.

You can only set this value if supportsVideoMaxFrameDuration is YES.
