- * <h3>State Diagram</h3>
- *
- * <p>Playback control of audio/video files and streams is managed as a state
- * machine. The following diagram shows the life cycle and the states of a
- * MediaPlayer2 object driven by the supported playback control operations.
- * The ovals represent the states a MediaPlayer2 object may reside
- * in. The arcs represent the playback control operations that drive the object
- * state transition. There are two types of arcs. The arcs with a single arrow
- * head represent synchronous method calls, while those with
- * a double arrow head represent asynchronous method calls.</p>
- *
- * <p><img src="../../../images/mediaplayer_state_diagram.gif"
- *         alt="MediaPlayer State diagram"
- *         border="0" /></p>
- *
- * <p>From this state diagram, one can see that a MediaPlayer2 object has the
- *    following states:</p>
- * <ul>
- *     <li>When a MediaPlayer2 object is just created using <code>new</code> or
- *         after {@link #reset()} is called, it is in the <em>Idle</em> state; and after
- *         {@link #close()} is called, it is in the <em>End</em> state. Between these
- *         two states is the life cycle of the MediaPlayer2 object.
- *         <ul>
- *         <li>There is a subtle but important difference between a newly constructed
- *         MediaPlayer2 object and the MediaPlayer2 object after {@link #reset()}
- *         is called. It is a programming error to invoke methods such
- *         as {@link #getCurrentPosition()},
- *         {@link #getDuration()}, {@link #getVideoHeight()},
- *         {@link #getVideoWidth()}, {@link #setAudioAttributes(AudioAttributes)},
- *         {@link #setLooping(boolean)},
- *         {@link #setVolume(float, float)}, {@link #pause()}, {@link #play()},
- *         {@link #seekTo(long, int)} or
- *         {@link #prepareAsync()} in the <em>Idle</em> state for both cases. If any of these
- *         methods is called right after a MediaPlayer2 object is constructed,
- *         the user supplied callback method OnErrorListener.onError() won't be
- *         called by the internal player engine and the object state remains
- *         unchanged; but if these methods are called right after {@link #reset()},
- *         the user supplied callback method OnErrorListener.onError() will be
- *         invoked by the internal player engine and the object will be
- *         transfered to the <em>Error</em> state. </li>
- *         <li>It is also recommended that once
- *         a MediaPlayer2 object is no longer being used, call {@link #close()} immediately
- *         so that resources used by the internal player engine associated with the
- *         MediaPlayer2 object can be released immediately. Resource may include
- *         singleton resources such as hardware acceleration components and
- *         failure to call {@link #close()} may cause subsequent instances of
- *         MediaPlayer2 objects to fallback to software implementations or fail
- *         altogether. Once the MediaPlayer2
- *         object is in the <em>End</em> state, it can no longer be used and
- *         there is no way to bring it back to any other state. </li>
- *         <li>Furthermore,
- *         the MediaPlayer2 objects created using <code>new</code> is in the
- *         <em>Idle</em> state.
- *         </li>
- *         </ul>
- *         </li>
- *     <li>In general, some playback control operation may fail due to various
- *         reasons, such as unsupported audio/video format, poorly interleaved
- *         audio/video, resolution too high, streaming timeout, and the like.
- *         Thus, error reporting and recovery is an important concern under
- *         these circumstances. Sometimes, due to programming errors, invoking a playback
- *         control operation in an invalid state may also occur. Under all these
- *         error conditions, the internal player engine invokes a user supplied

- *         <ul>
- *         <li>It is important to note that once an error occurs, the
- *         MediaPlayer2 object enters the <em>Error</em> state (except as noted
- *         above), even if an error listener has not been registered by the application.</li>
- *         <li>In order to reuse a MediaPlayer2 object that is in the <em>
- *         Error</em> state and recover from the error,
- *         {@link #reset()} can be called to restore the object to its <em>Idle</em>
- *         state.</li>
- *         <li>It is good programming practice to have your application
- *         register a OnErrorListener to look out for error notifications from
- *         the internal player engine.</li>
- *         <li>IllegalStateException is
- *         thrown to prevent programming errors such as calling
- *         {@link #prepareAsync()}, {@link #setDataSource(DataSourceDesc)}, or

- *         </ul>
- *         </li>
- *     <li>Calling
- *         {@link #setDataSource(DataSourceDesc)}, or
- *         {@code setPlaylist} transfers a
- *         MediaPlayer2 object in the <em>Idle</em> state to the
- *         <em>Initialized</em> state.
- *         <ul>
- *         <li>An IllegalStateException is thrown if
- *         setDataSource() or setPlaylist() is called in any other state.</li>
- *         <li>It is good programming
- *         practice to always look out for <code>IllegalArgumentException</code>
- *         and <code>IOException</code> that may be thrown from
- *         <code>setDataSource</code> and <code>setPlaylist</code> methods.</li>
- *         </ul>
- *         </li>
- *     <li>A MediaPlayer2 object must first enter the <em>Prepared</em> state
- *         before playback can be started.
- *         <ul>
- *         <li>{@link #prepareAsync()} first transfers the object to the
- *         <em>Preparing</em> state after the
- *         call returns (which occurs almost right way) while the internal
- *         player engine continues working on the rest of preparation work
- *         until the preparation work completes. When the preparation completes,
- *         the internal player engine then calls a user supplied callback method,
- *         onPrepared() of the EventCallback interface, if an
- *         EventCallback is registered beforehand via {@link
- *         #registerEventCallback(Executor, EventCallback)}.</li>
- *         <li>It is important to note that
- *         the <em>Preparing</em> state is a transient state, and the behavior
- *         of calling any method with side effect while a MediaPlayer2 object is
- *         in the <em>Preparing</em> state is undefined.</li>
- *         <li>An IllegalStateException is
- *         thrown if {@link #prepareAsync()} is called in
- *         any other state.</li>
- *         <li>While in the <em>Prepared</em> state, properties
- *         such as audio/sound volume, screenOnWhilePlaying, looping can be
- *         adjusted by invoking the corresponding set methods.</li>
- *         </ul>
- *         </li>
- *     <li>To start the playback, {@link #play()} must be called. After
- *         {@link #play()} returns successfully, the MediaPlayer2 object is in the
- *         <em>Started</em> state. {@link #isPlaying()} can be called to test
- *         whether the MediaPlayer2 object is in the <em>Started</em> state.
- *         <ul>
- *         <li>While in the <em>Started</em> state, the internal player engine calls
- *         a user supplied EventCallback.onBufferingUpdate() callback
- *         method if an EventCallback has been registered beforehand
- *         via {@link #registerEventCallback(Executor, EventCallback)}.
- *         This callback allows applications to keep track of the buffering status
- *         while streaming audio/video.</li>
- *         <li>Calling {@link #play()} has not effect
- *         on a MediaPlayer2 object that is already in the <em>Started</em> state.</li>
- *         </ul>
- *         </li>
- *     <li>Playback can be paused and stopped, and the current playback position
- *         can be adjusted. Playback can be paused via {@link #pause()}. When the call to
- *         {@link #pause()} returns, the MediaPlayer2 object enters the
- *         <em>Paused</em> state. Note that the transition from the <em>Started</em>
- *         state to the <em>Paused</em> state and vice versa happens
- *         asynchronously in the player engine. It may take some time before
- *         the state is updated in calls to {@link #isPlaying()}, and it can be
- *         a number of seconds in the case of streamed content.
- *         <ul>
- *         <li>Calling {@link #play()} to resume playback for a paused
- *         MediaPlayer2 object, and the resumed playback
- *         position is the same as where it was paused. When the call to
- *         {@link #play()} returns, the paused MediaPlayer2 object goes back to
- *         the <em>Started</em> state.</li>
- *         <li>Calling {@link #pause()} has no effect on
- *         a MediaPlayer2 object that is already in the <em>Paused</em> state.</li>
- *         </ul>
- *         </li>
- *     <li>The playback position can be adjusted with a call to
- *         {@link #seekTo(long, int)}.
- *         <ul>
- *         <li>Although the asynchronuous {@link #seekTo(long, int)}
- *         call returns right away, the actual seek operation may take a while to
- *         finish, especially for audio/video being streamed. When the actual
- *         seek operation completes, the internal player engine calls a user
- *         supplied EventCallback.onSeekComplete() if an EventCallback
- *         has been registered beforehand via
- *         {@link #registerEventCallback(Executor, EventCallback)}.</li>
- *         <li>Please
- *         note that {@link #seekTo(long, int)} can also be called in the other states,
- *         such as <em>Prepared</em>, <em>Paused</em> and <em>PlaybackCompleted
- *         </em> state. When {@link #seekTo(long, int)} is called in those states,
- *         one video frame will be displayed if the stream has video and the requested
- *         position is valid.
- *         </li>
- *         <li>Furthermore, the actual current playback position
- *         can be retrieved with a call to {@link #getCurrentPosition()}, which
- *         is helpful for applications such as a Music player that need to keep
- *         track of the playback progress.</li>
- *         </ul>
- *         </li>
- *     <li>When the playback reaches the end of stream, the playback completes.
- *         <ul>
- *         <li>If the looping mode was being set to <var>true</var>with
- *         {@link #setLooping(boolean)}, the MediaPlayer2 object shall remain in
- *         the <em>Started</em> state.</li>
- *         <li>If the looping mode was set to <var>false
- *         </var>, the player engine calls a user supplied callback method,
- *         EventCallback.onCompletion(), if an EventCallback is registered
- *         beforehand via {@link #registerEventCallback(Executor, EventCallback)}.
- *         The invoke of the callback signals that the object is now in the <em>
- *         PlaybackCompleted</em> state.</li>
- *         <li>While in the <em>PlaybackCompleted</em>
- *         state, calling {@link #play()} can restart the playback from the
- *         beginning of the audio/video source.</li>

+/**
+ * DynamicsProcessing is an audio effect for equalizing and changing dynamic range properties of the
+ * sound. It is composed of multiple stages including equalization, multi-band compression and
+ * limiter.
+ * <p>The number of bands and active stages is configurable, and most parameters can be controlled
+ * in realtime, such as gains, attack/release times, thresholds, etc.
+ * <p>The effect is instantiated and controlled by channels. Each channel has the same basic
+ * architecture, but all of their parameters are independent from other channels.
+ * <p>The basic channel configuration is:
+ * <pre>
+ *
+ *    Channel 0          Channel 1       ....       Channel N-1

+// is encountered directly after the span, it will be emitted. This leads to situations like the
+// following: "This <b> is </b> spaced" -> "This  is  spaced". Without spans, this would be properly
+// compressed: "This  is  spaced" -> "This is spaced".
+//
+// Untranslatable sections do not have the same problem:
+// "This <xliff:g> is </xliff:g> not spaced" -> "This is not spaced".
