Class FakeMultiPeriodLiveTimeline

java.lang.Object

- - com.google.android.exoplayer2.testutil.FakeMultiPeriodLiveTimeline
All Implemented Interfaces:Bundleable

public classFakeMultiPeriodLiveTimelineextends[Timeline](../Timeline.html "class in com.google.android.exoplayer2")

A fake Timeline that produces a live window with periods according to the available time range.

The parameters passed to the constructor define the availability start time, the window size and now. Use advanceNowUs(long) to advance the live window of the timeline accordingly.

The first available period with ID 0 (zero) starts at availabilityStartTimeUs. The live window starts at now - liveWindowDurationUs with the first period of the window having its ID relative to the first available period.

Periods are either of type content or ad as defined by the ad sequence pattern. A period is an ad if adSequencePattern[id % adSequencePattern.length] evaluates to true. Ad periods have a duration of AD_PERIOD_DURATION_MS and content periods have a duration of PERIOD_DURATION_MS.

Constructor Detail

FakeMultiPeriodLiveTimeline

public FakeMultiPeriodLiveTimeline(long availabilityStartTimeMs,
                                   long liveWindowDurationUs,
                                   long nowUs,
                                   boolean[] adSequencePattern,

                                   boolean playedAds)

Creates an instance. Parameters:availabilityStartTimeMs - The start time of the available time range, UNIX epoch in milliseconds.liveWindowDurationUs - The duration of the live window.nowUs - The current time that determines the end of the live window.adSequencePattern - The repeating pattern of periods starting at availabilityStartTimeMs. True is an ad period, and false a content period.periodDurationMsPattern - The repeating pattern of periods durations starting at availabilityStartTimeMs, in milliseconds. Must have the same length as adSequencePattern.isContentTimeline - Whether the timeline is a content timeline without AdPlaybackStates.populateAds - Whether to populate ads in the same way if an ad event has been received.playedAds - Whether ads should be marked as played if populated.

Method Detail

advanceNowUs

public void advanceNowUs(long durationUs)

Advances the live window by the given duration, in microseconds.

getWindowStartTimeUs

public long getWindowStartTimeUs()

The window's start time in microseconds since the Unix epoch, or C.TIME_UNSET if unknown or not applicable.

getPeriodStartTimeUs

public long getPeriodStartTimeUs(int periodIndex)

Returns the period start time since Unix epoch, in microseconds.

Note: The returned value has millisecond precision only, so the trailing 3 digits are always zeros.
