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.
A default TrackSelector suitable for most use cases.
Modifying parameters
Track selection parameters should be modified by obtaining a TrackSelectionParameters.Builder initialized with the current TrackSelectionParameters from the player. The desired modifications can be made on the builder, and the resulting TrackSelectionParameters can then be built and set on the player:
```
 player.setTrackSelectionParameters(
     player.getTrackSelectionParameters()
         .buildUpon()
         .setMaxVideoSizeSd()
         .setPreferredAudioLanguage("de")
         .build());
 
```
Some specialized parameters are only available in the extended DefaultTrackSelector.Parameters class, which can be retrieved and modified in a similar way by calling methods directly on this class:
```
 defaultTrackSelector.setParameters(
     defaultTrackSelector.getParameters()
         .buildUpon()
         .setTunnelingEnabled(true)
         .build());
 
```

    Called by selectAllTracks(MappedTrackInfo, int[][][], int[], Parameters) to create a ExoTrackSelection for a renderer whose type is neither video, audio or text.
    
    Parameters:
    
    trackType - The type of the renderer.
    
    groups - The TrackGroupArray mapped to the renderer.
    
    formatSupport - The RendererCapabilities.Capabilities for each mapped track, indexed by track group and track (in that order).
    
    params - The selector's current constraint parameters.
    
    Returns:
    
    The ExoTrackSelection for the renderer, or null if no selection was made.

```
    Deprecated.
    
    Returns a score for how well a language specified in a Format matches a given language.
    
    Parameters:
    
    format - The Format.
    
    language - The language, or null.
    
    allowUndeterminedFormatLanguage - Whether matches with an empty or undetermined format language tag are allowed.
    
    Returns:
    
    A score of 4 if the languages match fully, a score of 3 if the languages match partly, a score of 2 if the languages don't match but belong to the same main language, a score of 1 if the format language is undetermined and such a match is allowed, and a score of 0 if the languages don't match at all.
