Instance Property

minFrameDuration

The minimum duration of the track’s frames.

Declaration

@property(nonatomic, readonly) CMTime minFrameDuration;

Discussion

A track’s minimum frame duration is the reciprocal of its maximum frame rate. For instance, a video track with a maximum frame rate of 30 frames per second would have a minimum frame duration of 1/30 (or 0.033). The value of this property is kCMTimeInvalid if the track’s minimum frame duration is unknown or cannot be calculated.
