Sets whether a text track with undetermined language should be selected if no track with a preferred language is available, or if the preferred language is unset.

Parameters
selectUndeterminedTextLanguage: Boolean

Whether a text track with undetermined language should be selected if no preferred language track is available.

setSelectionOverride

@CanIgnoreReturnValue
fun setSelectionOverride(
    rendererIndex: Int,
    groups: TrackGroupArray!,
    override: DefaultTrackSelector.SelectionOverride?
): DefaultTrackSelector.ParametersBuilder!

Overrides the track selection for the renderer at the specified index.

When the TrackGroupArray mapped to the renderer matches the one provided, the override is applied. When the TrackGroupArray does not match, the override has no effect. The override replaces any previous override for the specified TrackGroupArray for the specified Renderer.

Passing a null override will cause the renderer to be disabled when the mapped to it matches the one provided. When the TrackGroupArray does not match a null override has no effect. Hence a null override differs from disabling the renderer using setRendererDisabled because the renderer is disabled conditionally on the TrackGroupArray mapped to it, where-as setRendererDisabled disables the renderer unconditionally.

To remove overrides use clearSelectionOverride, clearSelectionOverrides or clearSelectionOverrides.

Parameters
rendererIndex: Int

The renderer index.

groups: TrackGroupArray!

The TrackGroupArray for which the override should be applied.

override: DefaultTrackSelector.SelectionOverride?

The override.

disabled: Boolean

Whether the track type should be disabled.

setTunnelingEnabled

@CanIgnoreReturnValue
fun setTunnelingEnabled(tunnelingEnabled: Boolean): DefaultTrackSelector.ParametersBuilder!

Sets whether to enable tunneling if possible. Tunneling will only be enabled if it's supported by the audio and video renderers for the selected tracks.

Tunneling is known to have many device specific issues and limitations. Manual testing is strongly recommended to check that the media plays correctly when this option is enabled. See [#9661](https://github.com/google/ExoPlayer/issues/9661), [#9133](https://github.com/google/ExoPlayer/issues/9133), [#9317](https://github.com/google/ExoPlayer/issues/9317), [#9502](https://github.com/google/ExoPlayer/issues/9502).
