com.google.android.exoplayer2.Timeline.Window

Enclosing class:

Timeline

public static final class Timeline.Window
extends java.lang.Object

Holds information about a window in a Timeline. A window defines a region of media currently available for playback along with additional information such as whether seeking is supported within the window. The figure below shows some of the information defined by a window, as well as how this information relates to corresponding Timeline.Periods in the timeline.

Field Detail

tag

@Nullable
public java.lang.Object tag

A tag for the window. Not necessarily unique.

presentationStartTimeMs

public long presentationStartTimeMs

The start time of the presentation to which this window belongs in milliseconds since the epoch, or C.TIME_UNSET if unknown or not applicable. For informational purposes only.

windowStartTimeMs

public long windowStartTimeMs

The window's start time in milliseconds since the epoch, or C.TIME_UNSET if unknown or not applicable. For informational purposes only.

isSeekable

public boolean isSeekable

Whether it's possible to seek within this window.

isDynamic

public boolean isDynamic

Whether this window may change when the timeline is updated.

firstPeriodIndex

public int firstPeriodIndex

The index of the first period that belongs to this window.

lastPeriodIndex

public int lastPeriodIndex

The index of the last period that belongs to this window.

defaultPositionUs

public long defaultPositionUs

The default position relative to the start of the window at which to begin playback, in microseconds. May be C.TIME_UNSET if and only if the window was populated with a non-zero default position projection, and if the specified projection cannot be performed whilst remaining within the bounds of the window.

durationUs

public long durationUs

The duration of this window in microseconds, or C.TIME_UNSET if unknown.

positionInFirstPeriodUs

public long positionInFirstPeriodUs
