Class TransportPosition

java.lang.Object
  net.sf.jack4j.TransportPosition

All Implemented Interfaces:

java.lang.Cloneable

public class TransportPosition
extends java.lang.Object
implements java.lang.Cloneable

Contains information about current state of Jack transport.

The structure contains fields listed below. Note that some of the fields may be uninitialized; to obtain information about which fields have valid values, see getValidBits() or getValidBitsSet() methods.

usecs

time in microseconds, monotonic, free-rolling counter

frameRate

current frame rate (per second)

frame

frame number; this field is always present

validBits

indicates which fields contain valid values, decode using JackPositionBit

validBitsSet

same as validBits, but decoded into more convenient EnumSet

bar

current bar

beat

current beat-within-bar

tick

current tick-within-beat

barStartTick

beatsPerBar

time signature "numerator"

beatType

time signature "denominator"

ticksPerBeat

beatsPerMinute

frameTime

current time in seconds

nextTime

next sequential frame_time (unless repositioned)

bbtOffset

bar-beat-tick offset (how many frames passed since the start of current tick)

audioFramesPerVideoFrame

number of audio frames per video frame

videoOffset

audio frame at which the first video frame in this cycle occurs
