- Field Detail
  - DEFAULT_WITHOUT_CONTEXT
```
public static final TrackSelectionParameters DEFAULT_WITHOUT_CONTEXT
```
    An instance with default values, except those obtained from the Context.
    If possible, use getDefaults(Context) instead.
    This instance will not have the following settings:
    
    Viewport constraints configured for the primary display.
    Preferred text language and role flags configured to the accessibility settings of CaptioningManager.
  - DEFAULT
```
@Deprecated
public static final TrackSelectionParameters DEFAULT
```
    Deprecated.
    This instance is not configured using Context constraints. Use getDefaults(Context) instead.
  - CREATOR
```
public static final Parcelable.Creator<TrackSelectionParameters> CREATOR
```
  - maxVideoWidth
```
public final int maxVideoWidth
```
    Maximum allowed video width in pixels. 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 in pixels. 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 in hertz. The default value is Integer.MAX_VALUE (i.e. no constraint).
  - maxVideoBitrate
```
public final int maxVideoBitrate
```
    Maximum allowed video bitrate in bits per second. The default value is Integer.MAX_VALUE (i.e. no constraint).
  - minVideoWidth
```
public final int minVideoWidth
```
    Minimum allowed video width in pixels. The default value is 0 (i.e. no constraint).
