- Field Detail
  - DEFAULT
```
public static final DefaultTrackSelector.Parameters DEFAULT
```
    An instance with default values.
  - preferredAudioLanguage
```
@Nullable
public final java.lang.String preferredAudioLanguage
```
    The preferred language for audio and forced text tracks, as an ISO 639-2/T tag. null selects the default track, or the first track if there's no default. The default value is null.
  - preferredTextLanguage
```
@Nullable
public final java.lang.String preferredTextLanguage
```
    The preferred language for text tracks as an ISO 639-2/T tag. null selects the default track if there is one, or no track otherwise. The default value is null.
  - selectUndeterminedTextLanguage
```
public final boolean selectUndeterminedTextLanguage
```
    Whether a text track with undetermined language should be selected if no track with preferredTextLanguage is available, or if preferredTextLanguage is unset. The default value is false.
  - disabledTextTrackSelectionFlags
```
public final int disabledTextTrackSelectionFlags
```
    Bitmask of selection flags that are disabled for text track selections. See C.SelectionFlags. The default value is 0 (i.e. no flags).
  - maxVideoWidth
```
public final int maxVideoWidth
```
    Maximum allowed video width. The default value is Integer.MAX_VALUE (i.e. no constraint).
    To constrain adaptive video track selections to be suitable for a given viewport (the region of the display within which video will be played), use (viewportWidth, viewportHeight and viewportOrientationMayChange) instead.
  - maxVideoHeight
```
public final int maxVideoHeight
```
    Maximum allowed video height. The default value is Integer.MAX_VALUE (i.e. no constraint).
    To constrain adaptive video track selections to be suitable for a given viewport (the region of the display within which video will be played), use (viewportWidth, viewportHeight and viewportOrientationMayChange) instead.
  - maxVideoFrameRate
```
public final int maxVideoFrameRate
```
    Maximum allowed video frame rate. The default value is Integer.MAX_VALUE (i.e. no constraint).
  - maxVideoBitrate
```
public final int maxVideoBitrate
```
    Maximum video bitrate. The default value is Integer.MAX_VALUE (i.e. no constraint).
  - exceedVideoConstraintsIfNecessary
```
public final boolean exceedVideoConstraintsIfNecessary
```
    Whether to exceed the maxVideoWidth, maxVideoHeight and maxVideoBitrate constraints when no selection can be made otherwise. The default value is true.
  - viewportWidth
```
public final int viewportWidth
```
    Viewport width in pixels. Constrains video track selections for adaptive content so that only tracks suitable for the viewport are selected. The default value is Integer.MAX_VALUE (i.e. no constraint).
  - viewportHeight
```
public final int viewportHeight
```
    Viewport height in pixels. Constrains video track selections for adaptive content so that only tracks suitable for the viewport are selected. The default value is Integer.MAX_VALUE (i.e. no constraint).
  - viewportOrientationMayChange
```
public final boolean viewportOrientationMayChange
```
    Whether the viewport orientation may change during playback. Constrains video track selections for adaptive content so that only tracks suitable for the viewport are selected. The default value is true.
  - forceLowestBitrate
```
public final boolean forceLowestBitrate
```
    Whether to force selection of the single lowest bitrate audio and video tracks that comply with all other constraints. The default value is false.
  - forceHighestSupportedBitrate
```
public final boolean forceHighestSupportedBitrate
```
    Whether to force selection of the highest bitrate audio and video tracks that comply with all other constraints. The default value is false.
  - allowMixedMimeAdaptiveness
```
public final boolean allowMixedMimeAdaptiveness
```
    Whether to allow adaptive selections containing mixed mime types. The default value is false.
  - allowNonSeamlessAdaptiveness

```
    Whether to allow adaptive selections where adaptation may not be completely seamless. The default value is true.
  - exceedRendererCapabilitiesIfNecessary
```
public final boolean exceedRendererCapabilitiesIfNecessary
```
    Whether to exceed renderer capabilities when no selection can be made otherwise.
    This parameter applies when all of the tracks available for a renderer exceed the renderer's reported capabilities. If the parameter is true then the lowest quality track will still be selected. Playback may succeed if the renderer has under-reported its true capabilities. If false then no track will be selected. The default value is true.
  - tunnelingAudioSessionId
```
public final int tunnelingAudioSessionId
```
    The audio session id to use when tunneling, or C.AUDIO_SESSION_ID_UNSET if tunneling is disabled. The default value is C.AUDIO_SESSION_ID_UNSET (i.e. tunneling is disabled).
  - CREATOR
