You can also specify a number value of 2 or 3 for the reset parameter, which is useful when

playing recorded stream files that contain message data. These values are analogous to

false (0)

and true (1), respectively: a value of 2 maintains a playlist, and a value of 3 resets the playlist.

However, the difference is that specifying either

2 or 3 for reset returns all messages in the

specified recorded stream at once, rather than at the intervals which the messages were originally

recorded (the default behavior).

remoteConnection A reference to a NetConnection object that is used to connect to a remote

server. The requested stream plays from the remote server if this parameter is provided. This

parameter is optional.

Returns

A Boolean value: true if the Stream.play call is accepted by the server and added to the playlist;

false otherwise. The Stream.play method can fail if the server fails to find the stream or if an

error occurs. To get information about the

Stream.play call, you can define a Stream.onStatus

handler to catch the play status or error.

If the

streamName parameter is false, the stream stops playing. A Boolean value of true is

returned if the stop succeeds;

false otherwise.

Description

Method; controls the data source of a stream with an optional start time, duration, and reset flag

to flush any previously playing stream. The

Stream.play method also has a parameter that lets

you reference a NetConnection object to play a stream from another server. The Stream.play

method allows you to do the following:

• Chain streams between servers.

• Create a hub to switch between live streams and recorded streams.

• Combine different steams into a recorded stream.

You can combine multiple streams to create a playlist for clients. The server-side Stream.play

method behaves a bit differently than the

NetStream.play method on the client side. A play call

on the server is similar to a

publish call on the client. It controls the source of the data that is

coming into a stream. When you call Stream.play on the server, the server becomes the

publisher. Because the server has a higher priority than the client, the client is forced to unpublish

from the stream if the server calls a

play method on the same stream.

In general, if any recorded streams are included in a server playlist, you cannot play the server

stream as a live stream.

Note: A stream that plays from a remote server by means of the NetConnection object is a live stream.

If you require a value to begin a stream, you may need to change the Application.xml file’s

“Enhanced seeking” flag at the server. “Enhanced seeking” is a Boolean flag in the

Application.xml file. By default, this flag is set to

false. When a play occurs, the server seeks to

the closest video keyframe possible and starts from that keyframe. For example, if you want to

play at time 15, and there are keyframes only at time 11 and time 17, seeking will start from time

17 instead of time 15. This is an approximate seeking method that works well with compressed

streams.
