Field Detail

MAX_EXPOSED_PERIODS

public static final int MAX_EXPOSED_PERIODS

The maximum number of periods that can be exposed by the source. The value of this constant is large enough to cause indefinite looping in practice (the total duration of the looping source will be approximately five years if the duration of each period is one second).

Constructor Detail

LoopingMediaSource

public LoopingMediaSource(MediaSource childSource)

Loops the provided source indefinitely.

Parameters:

childSource - The MediaSource to loop.

LoopingMediaSource

public LoopingMediaSource(MediaSource childSource,
                          int loopCount)

Loops the provided source a specified number of times.

Parameters:

childSource - The MediaSource to loop.

loopCount - The desired number of loops. Must be strictly positive. The actual number of loops will be capped at the maximum that can achieved without causing the number of periods exposed by the source to exceed MAX_EXPOSED_PERIODS.

Method Detail

prepareSource

public void prepareSource(ExoPlayer player,
                          boolean isTopLevelSource,
                          MediaSource.Listener listener)

Description copied from interface: MediaSource

Starts preparation of the source.

Specified by:

prepareSource in interface MediaSource

Parameters:

player - The player for which this source is being prepared.

isTopLevelSource - Whether this source has been passed directly to ExoPlayer.prepare(MediaSource) or ExoPlayer.prepare(MediaSource, boolean, boolean). If false, this source is being prepared by another source (e.g. ConcatenatingMediaSource) for composition.

listener - The listener for source events.

maybeThrowSourceInfoRefreshError

public void maybeThrowSourceInfoRefreshError()
                                      throws java.io.IOException

Description copied from interface: MediaSource

Throws any pending error encountered while loading or refreshing source information.

Specified by:

maybeThrowSourceInfoRefreshError in interface MediaSource

Throws:

java.io.IOException

createPeriod

public MediaPeriod createPeriod(int index,
                                Allocator allocator,
                                long positionUs)

Description copied from interface: MediaSource

Returns a new MediaPeriod corresponding to the period at the specified index. This method may be called multiple times with the same index without an intervening call to MediaSource.releasePeriod(MediaPeriod).

Specified by:

createPeriod in interface MediaSource

Parameters:

index - The index of the period.

allocator - An Allocator from which to obtain media buffer allocations.

positionUs - The player's current playback position.

Returns:

A new MediaPeriod.

releasePeriod

public void releasePeriod(MediaPeriod mediaPeriod)

Description copied from interface: MediaSource

Releases the period.

Specified by:

releasePeriod in interface MediaSource

Parameters:

mediaPeriod - The period to release.

releaseSource

public void releaseSource()

Description copied from interface: MediaSource

Releases the source.

This method should be called when the source is no longer required. It may be called in any state.

Specified by:

releaseSource in interface MediaSource
