Declaration
func maySamplesWithLaterDecodeTimeStampsHavePresentationTimeStamps(earlierThan cursor: AVSampleCursor) -> BoolParameters
- cursor:
An instance of
AVSampleCursorwith which to test the sample reordering boundary.
Return Value
true if it’s possible for any sample later in decode order than the sample at the position of the receiver can have a presentation timestamp earlier than that of the specified sample cursor; otherwise, false.
Discussion
Undefined results occur if this cursor and the passed in cursor reference different sequences of samples, such as when they’re created by different instances of AVAssetTrack.
