 /**
  * Dynamic streaming play method.
  *
  * <p>The following properties are supported on the play options:
  *
  * <pre>
  * streamName: String. The name of the stream to play or the new stream to switch to.
  * oldStreamName: String. The name of the initial stream that needs to be switched out. This is not needed and ignored
  * when play2 is used for just playing the stream and not switching to a new stream.
  * start: Number. The start time of the new stream to play, just as supported by the existing play API. and it has the
  * same defaults. This is ignored when the method is called for switching (in other words, the transition
  * is either NetStreamPlayTransition.SWITCH or NetStreamPlayTransitions.SWAP)
  * len: Number. The duration of the playback, just as supported by the existing play API and has the same defaults.
  * transition: String. The transition mode for the playback command. It could be one of the following:
  * NetStreamPlayTransitions.RESET
  * NetStreamPlayTransitions.APPEND
  * NetStreamPlayTransitions.SWITCH
  * NetStreamPlayTransitions.SWAP
  * </pre>
  *
  * NetStreamPlayTransitions:
  *
  * <pre>
  * APPEND : String = "append" - Adds the stream to a playlist and begins playback with the first stream.
  * APPEND_AND_WAIT : String = "appendAndWait" - Builds a playlist without starting to play it from the first stream.
  * RESET : String = "reset" - Clears any previous play calls and plays the specified stream immediately.
  * RESUME : String = "resume" - Requests data from the new connection starting from the point at which the previous connection ended.
  * STOP : String = "stop" - Stops playing the streams in a playlist.
  * SWAP : String = "swap" - Replaces a content stream with a different content stream and maintains the rest of the playlist.
  * SWITCH : String = "switch" - Switches from playing one stream to another stream, typically with streams of the same content.
  * </pre>
