FakeMediaPeriod.TrackDataFactory

public interface FakeMediaPeriod.TrackDataFactory

A factory to create the test data for a particular track.

Summary

Public methods
abstract List<FakeSampleStream.FakeSampleStreamItem>
create(Format format, MediaSource.MediaPeriodId mediaPeriodId)

Returns the list of FakeSampleStream.FakeSampleStreamItems that will be written the sample queue during playback.
default static FakeMediaPeriod.TrackDataFactory
samplesWithRateDurationAndKeyframeInterval(
    long initialSampleTimeUs,
    float sampleRate,
    long durationUs,
    int keyFrameInterval
)

Creates a TrackDataFactory which generates samples at the given rate to cover the provided duration, with a specified key frame interval.
default static FakeMediaPeriod.TrackDataFactory
singleSampleWithTimeUs(long sampleTimeUs)

Returns a factory that always provides a single keyframe sample with time=sampleTimeUs and then end-of-stream.
