public final class TestSpeedProvider implements SpeedProvider

Summary

Public methods
`static TestSpeedProvider`	`createWithFrameCounts( AudioProcessor.AudioFormat audioFormat, int[] frameCounts, float[] speeds )` Creates a `TestSpeedProvider` instance.
`static TestSpeedProvider`	`createWithStartTimes(long[] startTimesUs, float[] speeds)` Creates a `TestSpeedProvider` instance.
`long`	`getNextSpeedChangeTimeUs(long timeUs)` Returns the timestamp of the next speed change, if there is any.
`float`	`getSpeed(long timeUs)` Returns the media speed from the provided timestamp.

static final SpeedProvider

DEFAULT

A speed provider with default values.

public static TestSpeedProvider createWithFrameCounts(
    AudioProcessor.AudioFormat audioFormat,
    int[] frameCounts,
    float[] speeds
)

Creates a TestSpeedProvider instance.

Parameters
`AudioProcessor.AudioFormat audioFormat`	the `AudioFormat`.
`int[] frameCounts`	The frame counts for which the same speed should be applied.
`float[] speeds`	The speeds corresponding to each frame count. Consecutive values must be distinct.

Returns
`TestSpeedProvider`	A `TestSpeedProvider`.

public static TestSpeedProvider createWithStartTimes(long[] startTimesUs, float[] speeds)

Creates a TestSpeedProvider instance.

Parameters
`long[] startTimesUs`	The speed change start times, in microseconds. The values must be distinct and in increasing order.
`float[] speeds`	The speeds corresponding to each start time. Consecutive values must be distinct.

Returns
`TestSpeedProvider`	A `TestSpeedProvider`.

public long getNextSpeedChangeTimeUs(long timeUs)

Returns the timestamp of the next speed change, if there is any.

Parameters
`long timeUs`	A timestamp, in microseconds.

Returns
`long`	The timestamp of the next speed change, in microseconds, or `TIME_UNSET` if there is no next speed change. If `timeUs` corresponds to a speed change, the returned value corresponds to the following speed change.

public float getSpeed(long timeUs)

Returns the media speed from the provided timestamp.

The media speed will stay the same until the next specified speed change.

Parameters
`long timeUs`	The timestamp of the media.

Returns
`float`	The speed that the media should be played at.
