/**
* Plays back a stream based on the supplied name, from the specified position for the given
* length of time.
*
* @param name - The name of a recorded file, or the identifier for live data. If
* @param start - The start time, in seconds. Allowed values are -2, -1, 0, or a positive number.
* The default value is -2, which looks for a live stream, then a recorded stream, and if it
* finds neither, opens a live stream. If -1, plays only a live stream. If 0 or a positive
* number, plays a recorded stream, beginning start seconds in.
* @param length - The duration of the playback, in seconds. Allowed values are -1, 0, or a
* positive number. The default value is -1, which plays a live or recorded stream until it
* ends. If 0, plays a single frame that is start seconds from the beginning of a recorded
* stream. If a positive number, plays a live or recorded stream for length seconds.
* @param reset - Whether to clear a playlist. The default value is 1 or true, which clears any
* previous play calls and plays name immediately. If 0 or false, adds the stream to a
* playlist. If 2, maintains the playlist and returns all stream messages at once, rather than
* at intervals. If 3, clears the playlist and returns all stream messages at once.

* 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>
