public final class CastPlayer extends BasePlayer


Player implementation that communicates with a Cast receiver app.

The behavior of this class depends on the underlying Cast session, which is obtained from the injected CastContext. To keep track of the session, isCastSessionAvailable can be queried and SessionAvailabilityListener can be implemented and attached to the player.

If no session is available, the player state will remain unchanged and calls to methods that alter it will be ignored. Querying the player state is possible even when no session is available, in which case, the last observed receiver app state is reported.

Methods should be called on the application's main thread.

public void moveMediaItems(int fromIndex, int toIndex, int newIndex)

Moves the media item range to the new index.

This method must only be called if COMMAND_CHANGE_MEDIA_ITEMS is available.

Parameters
int fromIndex

The start of the range to move. If the index is larger than the size of the playlist, the request is ignored.

int toIndex

The first item not to be included in the range (exclusive). If the index is larger than the size of the playlist, items up to the end of the playlist are moved.

int newIndex

The new index of the first media item of the range. If the new index is larger than the size of the remaining playlist after removing the range, the range is moved to the end of the playlist.

prepare

public void prepare()

Prepares the player.

This method must only be called if COMMAND_PREPARE is available.

This will move the player out of idle state and the player will start loading media and acquire resources needed for playback.

release

public void release()

Releases the player. This method must be called when the player is no longer required. The player must not be used after calling this method.

This method must only be called if COMMAND_RELEASE is available.

removeListener

public void removeListener(Player.Listener listener)

Unregister a listener registered through addListener. The listener will no longer receive events.

Parameters
Player.Listener listener

The listener to unregister.

removeMediaItems

public void removeMediaItems(int fromIndex, int toIndex)

Removes a range of media items from the playlist.

This method must only be called if COMMAND_CHANGE_MEDIA_ITEMS is available.

Parameters
int fromIndex

The index at which to start removing media items. If the index is larger than the size of the playlist, the request is ignored.

int toIndex

The index of the first item to be kept (exclusive). If the index is larger than the size of the playlist, media items up to the end of the playlist are removed.

replaceMediaItems

public void replaceMediaItems(
    int fromIndex,
    int toIndex,
    List<MediaItem> mediaItems
)

Replaces the media items at the given range of the playlist.

Implementations of this method may attempt to seamlessly continue playback if the currently playing media item is replaced with a compatible one (e.g. same URL, only metadata has changed).

This method must only be called if COMMAND_CHANGE_MEDIA_ITEMS is available.

Note that it is possible to replace a range with an arbitrary number of new items, so that the number of removed items defined by fromIndex and toIndex does not have to match the number of added items defined by mediaItems. As result, it may also change the index of subsequent items not touched by this operation.

Parameters
int fromIndex

The start of the range. If the index is larger than the size of the playlist, the request is ignored.

int toIndex

The first item not to be included in the range (exclusive). If the index is larger than the size of the playlist, items up to the end of the playlist are replaced.

List<MediaItem> mediaItems

The media items to replace the range with.

This method must only be called if COMMAND_CHANGE_MEDIA_ITEMS is available.

Parameters
List<MediaItem> mediaItems

The new media items.

boolean resetPosition

Whether the playback position should be reset to the default position in the first Timeline.Window. If false, playback will start from the position defined by getCurrentMediaItemIndex and getCurrentPosition.

This method must only be called if COMMAND_CHANGE_MEDIA_ITEMS is available.

Parameters
List<MediaItem> mediaItems

The new media items.

int startIndex

The MediaItem index to start playback from. If INDEX_UNSET is passed, the current position is not reset.

long startPositionMs

The position in milliseconds to start playback from. If TIME_UNSET is passed, the default position of the given MediaItem is used. In any case, if startIndex is set to INDEX_UNSET, this parameter is ignored and the position is not reset at all.

Throws
androidx.media3.common.IllegalSeekPositionException

If the provided startIndex is not within the bounds of the list of media items.

setPlayWhenReady

public void setPlayWhenReady(boolean playWhenReady)

Sets whether playback should proceed when getPlaybackState == STATE_READY.

If the player is already in the ready state then this method pauses and resumes playback.

This method must only be called if COMMAND_PLAY_PAUSE is available.

Parameters
boolean playWhenReady

Whether playback should proceed when ready.

setPlaybackParameters

public void setPlaybackParameters(PlaybackParameters playbackParameters)

Attempts to set the playback parameters. Passing DEFAULT resets the player to the default, which means there is no speed or pitch adjustment.

Playback parameters changes may cause the player to buffer. onPlaybackParametersChanged will be called whenever the currently active playback parameters change.

This method must only be called if COMMAND_SET_SPEED_AND_PITCH is available.

Parameters
PlaybackParameters playbackParameters

The playback parameters.

setPlaylistMetadata

public void setPlaylistMetadata(MediaMetadata mediaMetadata)

This method is not supported and does nothing.

Parameters
boolean shuffleModeEnabled

Whether shuffling is enabled.

setTrackSelectionParameters

public void setTrackSelectionParameters(TrackSelectionParameters parameters)

Unsupported parameters will be silently ignored.

Use getTrackSelectionParameters to retrieve the current parameters. For example, the following snippet restricts video to SD whilst keep other track selection parameters unchanged:

player.setTrackSelectionParameters(
  player.getTrackSelectionParameters()
        .buildUpon()
        .setMaxVideoSizeSd()
        .build())

This method must only be called if COMMAND_SET_TRACK_SELECTION_PARAMETERS is available.

stop

public void stop()

Stops playback without resetting the playlist. Use pause rather than this method if the intention is to pause playback.

Calling this method will cause the playback state to transition to STATE_IDLE and the player will release the loaded media and resources required for playback. The player instance can still be used by calling prepare again, and release must still be called on the player if it's no longer required.

Calling this method does not clear the playlist, reset the playback position or the playback error.

This method must only be called if COMMAND_STOP is available.
