ADOBE FLASH MEDIA INTERACTIVE SERVER

Server-Side ActionScript Language Reference

106

A server-side stream cannot subscribe to itself. For example, the following code is invalid:

// Client-side code

var ns = new NetStream

ns.publish("TestStream");

// Server-side code

st = Stream.get("TestStream");

st.play("TestStream");

Stream.record()

myStream.record(flag)

Records all the data passing through a Stream object and creates an FLV file of the recorded stream.

Note: The

Stream.record() method saves all streams as FLV files, even if the stream contains FLV, MP3, and MP4

content. H.264 data and AAC data is not copied to a recorded FLV file.

When you record a stream, the server creates an FLV file and stores it in the streams subdirectory of the application

folder. The server creates the streams directory and subdirectories for each application instance name. If a stream

isn’t associated with an application instance, it is stored in a subdirectory called _definst_ (default instance).

For example, a stream from the default lecture application instance would be stored here: applica-

tions\lectures\streams\_definst_. A stream from the monday lectures application instance would be stored here:

applications\lectures\streams\monday.

Note: The server creates these directories automatically; you don’t have to create one for each instance name.

Availability

Flash Communication Server 1

Parameters

flag One of the these values: "record", "append", or false. If the value is "record", the data file is overwritten if

it exists. If the value is "

append", the incoming data is appended to the end of the existing file. If the value is false,

any previous recording stops. By default, the value is "

record".

Returns

A boolean value of

true if the recording succeeds; otherwise, false.

Example

The following example opens a stream

s and, when it is open, plays smith and records it. Because no value is passed

to the

record() method, the default value, record, is passed.

// Start recording.

s = Stream.get("SurfVideos");

if (s){

s.play("smith");

s.record();

}

// Stop recording.

s = Stream.get("SurfVideos");

if (s){

s.record(false);

}
