- com.google.android.exoplayer2.source.BaseMediaSource
- - com.google.android.exoplayer2.source.CompositeMediaSource<Void>
  - - com.google.android.exoplayer2.source.LoopingMediaSource

All Implemented Interfaces:

MediaSource
```
public final class LoopingMediaSource
extends CompositeMediaSource<Void>
```
Loops a MediaSource a specified number of times.
Note: To loop a MediaSource indefinitely, it is usually better to use Player.setRepeatMode(int) instead of this class.

Method Summary

All Methods Instance Methods Concrete Methods Deprecated Methods
Modifier and Type	Method	Description
`MediaPeriod`	`createPeriod(MediaSource.MediaPeriodId id, Allocator allocator, long startPositionUs)`	Returns a new `MediaPeriod` identified by `periodId`.
`Timeline`	`getInitialTimeline()`	Returns the initial placeholder timeline that is returned immediately when the real timeline is not yet known, or null to let the player create an initial timeline.
`MediaItem`	`getMediaItem()`	Returns the `MediaItem` whose media is provided by the source.
`protected MediaSource.MediaPeriodId`	`getMediaPeriodIdForChildMediaPeriodId(Void id, MediaSource.MediaPeriodId mediaPeriodId)`	Returns the `MediaSource.MediaPeriodId` in the composite source corresponding to the specified `MediaSource.MediaPeriodId` in a child source.
`Object`	`getTag()`	Deprecated. Use `getMediaItem()` and `MediaItem.PlaybackProperties.tag` instead.
`boolean`	`isSingleWindow()`	Returns true if the media source is guaranteed to never have zero or more than one window.
`protected void`	`onChildSourceInfoRefreshed(Void id, MediaSource mediaSource, Timeline timeline)`	Called when the source info of a child source has been refreshed.
`protected void`	`prepareSourceInternal(TransferListener mediaTransferListener)`	Starts source preparation and enables the source, see `BaseMediaSource.prepareSource(MediaSourceCaller, TransferListener)`.
`void`	`releasePeriod(MediaPeriod mediaPeriod)`	Releases the period.

- Constructor Detail
  - LoopingMediaSource
```
public LoopingMediaSource(MediaSource childSource)
```
    Loops the provided source indefinitely. Note that it is usually better to use Player.setRepeatMode(int).
    
    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.
- Method Detail
  - getTag
```
@Deprecated
@Nullable
public Object getTag()
```
    Deprecated.
    Use getMediaItem() and MediaItem.PlaybackProperties.tag instead.
  - getMediaItem
```
public MediaItem getMediaItem()
```
    Description copied from interface: MediaSource
    
    Returns the MediaItem whose media is provided by the source.
  - getInitialTimeline
```
@Nullable
public Timeline getInitialTimeline()
```
    Description copied from interface: MediaSource
    
    Returns the initial placeholder timeline that is returned immediately when the real timeline is not yet known, or null to let the player create an initial timeline.
    The initial timeline must use the same uids for windows and periods that the real timeline will use. It also must provide windows which are marked as dynamic to indicate that the window is expected to change when the real timeline arrives.
    Any media source which has multiple windows should typically provide such an initial timeline to make sure the player reports the correct number of windows immediately.
  - isSingleWindow
```
public boolean isSingleWindow()
```
    Description copied from interface: MediaSource
    
    Returns true if the media source is guaranteed to never have zero or more than one window.
    The default implementation returns true.
    
    Returns:
    
    true if the source has exactly one window.
  - prepareSourceInternal
```
protected void prepareSourceInternal(@Nullable
                                     TransferListener mediaTransferListener)
```
    Description copied from class: BaseMediaSource
    
    Starts source preparation and enables the source, see BaseMediaSource.prepareSource(MediaSourceCaller, TransferListener). This method is called at most once until the next call to BaseMediaSource.releaseSourceInternal().
    
    Overrides:
    
    prepareSourceInternal in class CompositeMediaSource<Void>
    
    Parameters:
    
    mediaTransferListener - The transfer listener which should be informed of any media data transfers. May be null if no listener is available. Note that this listener should usually be only informed of transfers related to the media loads and not of auxiliary loads for manifests and other data.
  - createPeriod
```
public MediaPeriod createPeriod(MediaSource.MediaPeriodId id,
                                Allocator allocator,
                                long startPositionUs)
```
    Description copied from interface: MediaSource
    
    Returns a new MediaPeriod identified by periodId.
    Should not be called directly from application code.
    Must only be called if the source is enabled.
    
    Parameters:
    
    id - The identifier of the period.
    
    allocator - An Allocator from which to obtain media buffer allocations.
    
    startPositionUs - The expected start position, in microseconds.
    
    Returns:
    
    A new MediaPeriod.
  - releasePeriod
```
public void releasePeriod(MediaPeriod mediaPeriod)
```
    Description copied from interface: MediaSource
    
    Releases the period.
    Should not be called directly from application code.
    
    Parameters:
    
    mediaPeriod - The period to release.
  - onChildSourceInfoRefreshed
```
protected void onChildSourceInfoRefreshed(Void id,
                                          MediaSource mediaSource,
                                          Timeline timeline)
```
    Description copied from class: CompositeMediaSource
    
    Called when the source info of a child source has been refreshed.
    
    Specified by:
    
    onChildSourceInfoRefreshed in class CompositeMediaSource<Void>
    
    Parameters:
    
    id - The unique id used to prepare the child source.
    
    mediaSource - The child source whose source info has been refreshed.
    
    timeline - The timeline of the child source.
  - getMediaPeriodIdForChildMediaPeriodId
```
@Nullable
protected MediaSource.MediaPeriodId getMediaPeriodIdForChildMediaPeriodId(Void id,
                                                                          MediaSource.MediaPeriodId mediaPeriodId)
```
    Description copied from class: CompositeMediaSource
    
    Returns the MediaSource.MediaPeriodId in the composite source corresponding to the specified MediaSource.MediaPeriodId in a child source. The default implementation does not change the media period id.
    
    Overrides:
    
    getMediaPeriodIdForChildMediaPeriodId in class CompositeMediaSource<Void>
    
    Parameters:
    
    id - The unique id used to prepare the child source.
    
    mediaPeriodId - A MediaSource.MediaPeriodId of the child source.
    
    Returns:
    
    The corresponding MediaSource.MediaPeriodId in the composite source. Null if no corresponding media period id can be determined.
