Public functions
(Mutable)List<FakeSampleStream.FakeSampleStreamItem!>!
create(format: Format!, mediaPeriodId: MediaSource.MediaPeriodId!)

Returns the list of FakeSampleStream.FakeSampleStreamItems that will be written the sample queue during playback.
java-static FakeMediaPeriod.TrackDataFactory!
samplesWithRateDurationAndKeyframeInterval(
    initialSampleTimeUs: Long,
    sampleRate: Float,
    durationUs: Long,
    keyFrameInterval: Int
)

Creates a TrackDataFactory which generates samples at the given rate to cover the provided duration, with a specified key frame interval.
java-static FakeMediaPeriod.TrackDataFactory!

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