```
public interface Player
```
A media player interface defining traditional high-level functionality, such as the ability to play, pause, seek and query properties of the currently playing media.
This interface includes some convenience methods that can be implemented by calling other methods in the interface. BasePlayer implements these convenience methods so inheriting BasePlayer is recommended when implementing the interface so that only the minimal set of required methods can be implemented.
Some important properties of media players that implement this interface are:
- They can provide a Timeline representing the structure of the media being played, which can be obtained by calling getCurrentTimeline().
- They can provide a TrackGroupArray defining the currently available tracks, which can be obtained by calling getCurrentTrackGroups().
- They can provide a TrackSelectionArray defining which of the currently available tracks are selected to be rendered. This can be obtained by calling getCurrentTrackSelections()}.

  - setPlaybackParameters
```
void setPlaybackParameters(PlaybackParameters playbackParameters)
```
    Attempts to set the playback parameters. Passing PlaybackParameters.DEFAULT resets the player to the default, which means there is no speed or pitch adjustment.

    Parameters:
    
    playbackParameters - The playback parameters.
  - setPlaybackSpeed
```
void setPlaybackSpeed(float speed)
```
    Changes the rate at which playback occurs. The pitch is not changed.
    This is equivalent to setPlaybackParameters(getPlaybackParameters().withSpeed(speed)).
    
    Parameters:
    
    speed - The linear factor by which playback will be sped up. Must be higher than 0. 1 is normal speed, 2 is twice as fast, 0.5 is half normal speed...

    Calling this method does not clear the playlist, reset the playback position or the playback error.
  - stop
```
@Deprecated
void stop(boolean reset)
```
    Deprecated.
    Use stop() and clearMediaItems() (if reset is true) or just stop() (if reset is false). Any player error will be cleared when re-preparing the player.

    A concrete implementation may include null elements if it has a fixed number of renderer components, wishes to report a TrackSelection for each of them, and has one or more renderer components that is not assigned any selected tracks.
    
    See Also:
    
    Player.Listener.onTracksChanged(TrackGroupArray, TrackSelectionArray)
  - getCurrentStaticMetadata
```
List<Metadata> getCurrentStaticMetadata()
```
    Returns the current static metadata for the track selections.
    The returned metadataList is an immutable list of Metadata instances, where the elements correspond to the current track selections, or an empty list if there are no track selections or the selected tracks contain no static metadata.
    This metadata is considered static in that it comes from the tracks' declared Formats, rather than being timed (or dynamic) metadata, which is represented within a metadata track.
    
    See Also:
    
    Player.Listener.onStaticMetadataChanged(List)
  - getMediaMetadata
```
MediaMetadata getMediaMetadata()
```
    Returns the current combined MediaMetadata, or MediaMetadata.EMPTY if not supported.
    This MediaMetadata is a combination of the MediaItem.mediaMetadata and the static and dynamic metadata sourced from Player.Listener.onStaticMetadataChanged(List) and MetadataOutput.onMetadata(Metadata).

  - getNextWindowIndex
```
int getNextWindowIndex()
```
    Returns the index of the window that will be played if next() is called, which may depend on the current repeat mode and whether shuffle mode is enabled. Returns C.INDEX_UNSET if hasNext() is false.
    Note: When the repeat mode is REPEAT_MODE_ONE, this method behaves the same as when the current repeat mode is REPEAT_MODE_OFF. See REPEAT_MODE_ONE for more details.
  - getPreviousWindowIndex

    The offset is calculated as currentTime - playbackPosition, so should usually be positive.
    Note that this offset may rely on an accurate local time, so this method may return an incorrect value if the difference between system clock and server clock is unknown.
  - isCurrentWindowSeekable
```
boolean isCurrentWindowSeekable()
```
    Returns whether the current window is seekable, or false if the Timeline is empty.

  - clearVideoSurface
```
void clearVideoSurface()
```
    Clears any Surface, SurfaceHolder, SurfaceView or TextureView currently set on the player.
  - clearVideoSurface
```
void clearVideoSurface(@Nullable
                       Surface surface)
```
    Clears the Surface onto which video is being rendered if it matches the one passed. Else does nothing.
    
    Parameters:
    
    surface - The surface to clear.
  - setVideoSurface
```
void setVideoSurface(@Nullable
                     Surface surface)
```
    Sets the Surface onto which video will be rendered. The caller is responsible for tracking the lifecycle of the surface, and must clear the surface by calling setVideoSurface(null) if the surface is destroyed.
    If the surface is held by a SurfaceView, TextureView or SurfaceHolder then it's recommended to use setVideoSurfaceView(SurfaceView), setVideoTextureView(TextureView) or setVideoSurfaceHolder(SurfaceHolder) rather than this method, since passing the holder allows the player to track the lifecycle of the surface automatically.
    
    Parameters:
    
    surface - The Surface.
  - setVideoSurfaceHolder
```
void setVideoSurfaceHolder(@Nullable
                           SurfaceHolder surfaceHolder)
```
    Sets the SurfaceHolder that holds the Surface onto which video will be rendered. The player will track the lifecycle of the surface automatically.
    The thread that calls the SurfaceHolder.Callback methods must be the thread associated with getApplicationLooper().
    
    Parameters:
    
    surfaceHolder - The surface holder.
  - clearVideoSurfaceHolder
```
