Discussion

This key is always present in the userInfo dictionary for the kCMSampleBufferConduitNotification_UpcomingOutputPTSRangeChanged notification. If its value is kCFBooleanTrue, there is a possibility that upcoming frames may have earlier presentation timestamps than the frames previously provided to the conduit, and the dictionary also contains one or both of the kCMSampleBufferConduitNotificationParameter_MinUpcomingOutputPTS or kCMSampleBufferConduitNotificationParameter_MaxUpcomingOutputPTS keys providing further information. If its value is kCFBooleanFalse, there is no such possibility.
