Deprecated. com.google.android.exoplayer2 is deprecated. Please migrate to androidx.media3 (which contains the same ExoPlayer code). See the migration guide for more details, including a script to help with the migration.

Base class for TrackSelectors that first establish a mapping between TrackGroups and Renderers, and then from that mapping create a ExoTrackSelection for each renderer.

Deprecated.

Given mapped track information, returns a track selection and configuration for each renderer. Parameters:mappedTrackInfo - Mapped track information.rendererFormatSupports - The RendererCapabilities.Capabilities for each mapped track, indexed by renderer, track group and track (in that order).rendererMixedMimeTypeAdaptationSupport - The RendererCapabilities.AdaptiveSupport for mixed MIME type adaptation for the renderer.mediaPeriodId - The MediaSource.MediaPeriodId of the period for which tracks are to be selected.timeline - The Timeline holding the period for which tracks are to be selected.Returns:A pair consisting of the track selections and configurations for each renderer. A null configuration indicates the renderer should be disabled, in which case the track selection will also be null. A track selection may also be null for a non-disabled renderer if RendererCapabilities.getTrackType() is C.TRACK_TYPE_NONE.Throws:ExoPlaybackException - If an error occurs while selecting the tracks.
