FakeTrackSelection

FakeTrackSelection(rendererTrackGroup: TrackGroup!)

FakeTrackSelection(rendererTrackGroup: TrackGroup!, selectedIndex: Int)

fun disable(): Unit

Disables this track selection. No further dynamic changes via updateSelectedTrack, evaluateQueueSize or shouldCancelChunkLoad will happen after this call.

This method may only be called when the track selection is already enabled.

fun enable(): Unit

Enables the track selection. Dynamic changes via updateSelectedTrack, evaluateQueueSize or shouldCancelChunkLoad will only happen after this call.

This method may not be called when the track selection is already enabled.

fun equals(o: Any?): Boolean

fun evaluateQueueSize(
    playbackPositionUs: Long,
    queue: (Mutable)List<MediaChunk!>!
): Int

Returns the number of chunks that should be retained in the queue.

May be called by sources that load media in discrete MediaChunks and support discarding of buffered chunks.

To avoid excessive re-buffering, implementations should normally return the size of the queue. An example of a case where a smaller value may be returned is if network conditions have improved dramatically, allowing chunks to be discarded and re-buffered in a track of significantly higher quality. Discarding chunks may allow faster switching to a higher quality track in this case.

Note that even if the source supports discarding of buffered chunks, the actual number of discarded chunks is not guaranteed. The source will call updateSelectedTrack with the updated queue of chunks before loading a new chunk to allow switching to another quality.

This method will only be called when the selection is enabled and none of the MediaChunks in the queue are currently loading.

fun excludeTrack(index: Int, exclusionDurationMs: Long): Boolean

Attempts to exclude the track at the specified index in the selection, making it ineligible for selection by calls to updateSelectedTrack for the specified period of time.

Exclusion will fail if all other tracks are currently excluded. If excluding the currently selected track, note that it will remain selected until the next call to updateSelectedTrack.

This method will only be called when the selection is enabled.

fun getFormat(index: Int): Format!

Returns the format of the track at a given index in the selection.

fun getIndexInTrackGroup(index: Int): Int

Returns the index in the track group of the track at a given index in the selection.

fun getSelectedFormat(): Format!

Returns the Format of the individual selected track.

fun getSelectedIndexInTrackGroup(): Int

Returns the index in the track group of the individual selected track.

fun getSelectionData(): Any?

Returns optional data associated with the current track selection.

@C.SelectionReason
fun getSelectionReason(): Int

Returns the reason for the current track selection.

fun getTrackGroup(): TrackGroup!

Returns the TrackGroup to which the selected tracks belong.

fun getType(): Int

Returns an integer specifying the type of the selection, or TYPE_UNSET if not specified.

Track selection types are specific to individual applications, but should be defined starting from TYPE_CUSTOM_BASE to ensure they don't conflict with any types that may be added to the library in the future.

fun hashCode(): Int

fun indexOf(format: Format!): Int

Returns the index in the selection of the track with the specified format. The format is located by identity so, for example, selection.indexOf(selection.getFormat(index)) == index even if multiple selected tracks have formats that contain the same values.

fun indexOf(indexInTrackGroup: Int): Int

Returns the index in the selection of the track with the specified index in the track group.

fun isTrackExcluded(index: Int, nowMs: Long): Boolean

Returns whether the track at the specified index in the selection is excluded.

fun length(): Int

Returns the number of tracks in the selection.

fun onPlaybackSpeed(playbackSpeed: Float): Unit

Called to notify the selection of the current playback speed. The playback speed may affect adaptive track selection.

fun updateSelectedTrack(
    playbackPositionUs: Long,
    bufferedDurationUs: Long,
    availableDurationUs: Long,
    queue: (Mutable)List<MediaChunk!>!,
    mediaChunkIterators: Array<MediaChunkIterator!>!
): Unit

Updates the selected track for sources that load media in discrete MediaChunks.

This method will only be called when the selection is enabled.
