Parameters:

mediaSource - The MediaSource to be added to the list.

addMediaSource

public void addMediaSource(int index,
                           MediaSource mediaSource)

Adds a MediaSource to the playlist.

Parameters:

index - The index at which the new MediaSource will be inserted. This index must be in the range of 0 <= index <= getSize().

mediaSource - The MediaSource to be added to the list.

public void addMediaSources(Collection<MediaSource> mediaSources)

Appends multiple MediaSources to the playlist.

Parameters:

mediaSources - A collection of MediaSources to be added to the list. The media sources are added in the order in which they appear in this collection.

addMediaSources

public void addMediaSources(int index,
                            Collection<MediaSource> mediaSources)

Adds multiple MediaSources to the playlist.

Parameters:

index - The index at which the new MediaSources will be inserted. This index must be in the range of 0 <= index <= getSize().

mediaSources - A collection of MediaSources to be added to the list. The media sources are added in the order in which they appear in this collection.

removeMediaSource

public void removeMediaSource(int index)

Removes a MediaSource from the playlist.

Parameters:

index - The index at which the media source will be removed. This index must be in the range of 0 <= index < getSize().

moveMediaSource

public void moveMediaSource(int currentIndex,
                            int newIndex)

Moves an existing MediaSource within the playlist.

Parameters:

currentIndex - The current index of the media source in the playlist. This index must be in the range of 0 <= index < getSize().

newIndex - The target index of the media source in the playlist. This index must be in the range of 0 <= index < getSize().

getSize

public int getSize()

Returns the number of media sources in the playlist.

getMediaSource

public MediaSource getMediaSource(int index)

Returns the MediaSource at a specified index.

Parameters:

index - A index in the range of 0 <= index <= getSize().

Returns:

The MediaSource at this index.

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.
