* 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.
