Summary

Nested types
class FakeTrackSelector.FakeTrackSelectionFactory : ExoTrackSelection.Factory A factory for the androidx.media3.test.utils.FakeTrackSelection instances requested by the FakeTrackSelector.

Public constructors
FakeTrackSelector()
FakeTrackSelector(     fakeTrackSelectionFactory: FakeTrackSelector.FakeTrackSelectionFactory! )
FakeTrackSelector(mayReuseTrackSelection: Boolean)

Public functions
(Mutable)List<FakeTrackSelection!>!	getAllTrackSelections() Returns list of all FakeTrackSelections that this track selector has made so far.

Protected functions

Array<@NullableType ExoTrackSelection.Definition!>!

selectAllTracks(     mappedTrackInfo: MappingTrackSelector.MappedTrackInfo!,     @RendererCapabilities.Capabilities rendererFormatSupports: Array<Array<IntArray!>!>!,     @RendererCapabilities.AdaptiveSupport rendererMixedMimeTypeAdaptationSupports: IntArray!,     params: DefaultTrackSelector.Parameters! ) Called from selectTracks to make a track selection for each renderer, prior to overrides and disabled flags being applied.

Inherited Constants
From androidx.media3.exoplayer.trackselection.DefaultTrackSelector const Int SELECTION_ELIGIBILITY_ADAPTIVE = 2 Track is eligible for both a fixed selection and as part of an adaptive selection with multiple tracks. const Int SELECTION_ELIGIBILITY_FIXED = 1 Track is eligible for a fixed selection with one track. const Int SELECTION_ELIGIBILITY_NO = 0 Track is not eligible for selection.

Inherited functions
From androidx.media3.exoplayer.trackselection.DefaultTrackSelector DefaultTrackSelector.Parameters.Builder! buildUponParameters() Returns a new Parameters.Builder initialized with the current selection parameters. java-static Int getFormatLanguageScore(     format: Format!,     language: String?,     allowUndeterminedFormatLanguage: Boolean ) Returns a score for how well a language specified in a Format matches a given language.

Pair<ExoTrackSelection.Definition!, Int!>? selectImageTrack(     mappedTrackInfo: MappingTrackSelector.MappedTrackInfo!,     @RendererCapabilities.Capabilities rendererFormatSupports: Array<Array<IntArray!>!>!,     params: DefaultTrackSelector.Parameters! ) Called by selectAllTracks to create a ExoTrackSelection.Definition for an image track selection. ExoTrackSelection.Definition? selectOtherTrack(     trackType: Int,     groups: TrackGroupArray!,     @RendererCapabilities.Capabilities formatSupport: Array<IntArray!>!,     params: DefaultTrackSelector.Parameters! ) Called by selectAllTracks to create a ExoTrackSelection for a renderer whose type is neither video, audio or text. Pair<ExoTrackSelection.Definition!, Int!>? selectTextTrack(     mappedTrackInfo: MappingTrackSelector.MappedTrackInfo!,     @RendererCapabilities.Capabilities rendererFormatSupports: Array<Array<IntArray!>!>!,     params: DefaultTrackSelector.Parameters!,     selectedAudioLanguage: String? ) Called by selectAllTracks to create a ExoTrackSelection.Definition for a text track selection. Pair<Array<@NullableType RendererConfiguration!>!, Array<@NullableType ExoTrackSelection!>!>! selectTracks(     mappedTrackInfo: MappingTrackSelector.MappedTrackInfo!,     @RendererCapabilities.Capabilities rendererFormatSupports: Array<Array<IntArray!>!>!,     @RendererCapabilities.AdaptiveSupport rendererMixedMimeTypeAdaptationSupport: IntArray!,     mediaPeriodId: MediaSource.MediaPeriodId!,     timeline: Timeline! ) Given mapped track information, returns a track selection and configuration for each renderer. Pair<ExoTrackSelection.Definition!, Int!>? selectVideoTrack(     mappedTrackInfo: MappingTrackSelector.MappedTrackInfo!,     @RendererCapabilities.Capabilities rendererFormatSupports: Array<Array<IntArray!>!>!,     @RendererCapabilities.AdaptiveSupport mixedMimeTypeSupports: IntArray!,     params: DefaultTrackSelector.Parameters! ) Called by selectAllTracks to create a ExoTrackSelection.Definition for a video track selection. Unit setAudioAttributes(audioAttributes: AudioAttributes!) Called by the player to set the AudioAttributes that will be used for playback. Unit setParameters(     parametersBuilder: DefaultTrackSelector.Parameters.Builder! ) Atomically sets the provided parameters for track selection. Unit setParameters(     parametersBuilder: DefaultTrackSelector.ParametersBuilder! ) This function is deprecated. Use setParameters instead. Unit setParameters(parameters: TrackSelectionParameters!) Called by the player to provide parameters for track selection.
From androidx.media3.exoplayer.trackselection.MappingTrackSelector Unit onSelectionActivated(info: Any?) Called by the player when a TrackSelectorResult previously generated by selectTracks is activated. TrackSelectorResult! selectTracks(     rendererCapabilities: Array<RendererCapabilities!>!,     trackGroups: TrackGroupArray!,     periodId: MediaSource.MediaPeriodId!,     timeline: Timeline! ) Called by the player to perform a track selection.
From androidx.media3.exoplayer.trackselection.TrackSelector TrackSelectionParameters! getParameters() Returns the current parameters for track selection. Unit @CallSuper init(     listener: TrackSelector.InvalidationListener!,     bandwidthMeter: BandwidthMeter! ) Called by the player to initialize the selector. Unit invalidate() Calls onTrackSelectionsInvalidated to invalidate all previously generated track selections. Unit invalidateForRendererCapabilitiesChange(renderer: Renderer!) Calls onRendererCapabilitiesChanged to invalidate all previously generated track selections because a renderer's capabilities have changed.

Public constructors

FakeTrackSelector

FakeTrackSelector()

FakeTrackSelector

FakeTrackSelector(
    fakeTrackSelectionFactory: FakeTrackSelector.FakeTrackSelectionFactory!
)

Parameters
fakeTrackSelectionFactory: FakeTrackSelector.FakeTrackSelectionFactory!	The FakeTrackSelectionFactory used to create the FakeTrackSelection instances.

FakeTrackSelector

FakeTrackSelector(mayReuseTrackSelection: Boolean)

Parameters
mayReuseTrackSelection: Boolean	Whether this FakeTrackSelector will reuse s during track selection, when it finds previously-selected track selection using the same TrackGroup.

Public functions

getAllTrackSelections

fun getAllTrackSelections(): (Mutable)List<FakeTrackSelection!>!

Returns list of all FakeTrackSelections that this track selector has made so far.

Protected functions

selectAllTracks

protected fun selectAllTracks(
    mappedTrackInfo: MappingTrackSelector.MappedTrackInfo!,
    @RendererCapabilities.Capabilities rendererFormatSupports: Array<Array<IntArray!>!>!,
    @RendererCapabilities.AdaptiveSupport rendererMixedMimeTypeAdaptationSupports: IntArray!,
    params: DefaultTrackSelector.Parameters!
): Array<@NullableType ExoTrackSelection.Definition!>!

Called from selectTracks to make a track selection for each renderer, prior to overrides and disabled flags being applied.

The implementation should not account for overrides and disabled flags. Track selections generated by this method will be overridden to account for these properties.

If selection parameters include audioOffloadPreferences with audioOffloadMode set to AUDIO_OFFLOAD_MODE_REQUIRED then only audio tracks will be selected. If no audio track is supported in offload, then no track will be selected.

Parameters
mappedTrackInfo: MappingTrackSelector.MappedTrackInfo!	Mapped track information.
@RendererCapabilities.Capabilities rendererFormatSupports: Array<Array<IntArray!>!>!	The Capabilities for each mapped track, indexed by renderer, track group and track (in that order).
@RendererCapabilities.AdaptiveSupport rendererMixedMimeTypeAdaptationSupports: IntArray!	The AdaptiveSupport for mixed MIME type adaptation for the renderer.
params: DefaultTrackSelector.Parameters!	The parameters to use for the track selection.

Returns
Array<@NullableType ExoTrackSelection.Definition!>!	The ExoTrackSelection.Definitions for the renderers. A null entry indicates no selection was made.

Throws
androidx.media3.exoplayer.ExoPlaybackException	If an error occurs while selecting the tracks.
