NCManager  - AS3 Flash

When streaming from Flash Media Server (FMS), the bitrate property returns the value calculated from autodetection, not the value set through the bitrate() property.

Related API Elements

Exposes the fallbackServerName property indirectly or directly.

• Indirectly—Supply a second <meta base> in SMIL. The fallbackServerName property uses that base attribute. (The fallbackServerName property uses the server name only, nothing else.)
• Directly—Access the ncMgr property in FLVPlayback or VideoPlayer and set the fallbackServerName property or use the setProperty() method.

Whether the URL is for RTMP streaming from a Flash Media Server (FMS) or a progressive download. If the stream is an RTMP stream from an FMS, then true. If the stream is a progressive download of an HTTP, local or other file, then false.

Related API Elements

Reference to the NetConnection object.

Related API Elements

Height of the stream, in pixels. After the VideoPlayer.ncConnected() method is called, if the streamHeight property is less than 0, that indicates to the VideoPlayer object that there is no stream height information. If the VideoPlayer object has the scaleMode property set to VideoScaleMode.MAINTAIN_ASPECT_RATIO or VideoScaleMode.NO_SCALE, then this value will be used and the resizing will happen instantly, rather than waiting.

Related API Elements

Length of the stream, in seconds. After the VideoPlayer.ncConnected() method is called, if it returns undefined, null or less than 0, then the VideoPlayer object knows that there is no stream length information. If stream length information is returned, it overrides any existing steam length information including information set by the totalTime parameter of the VideoPlayer.play() method or the VideoPlayer.load() method or information received from the FLV file's metadata.

Related API Elements

The stream name passed into the NetStream.play() method.

Related API Elements

Width of the stream, in pixels. After the VideoPlayer.ncConnected() method is called, if the streamWidth property is less than 0, that indicates to the VideoPlayer object that there is no stream width information. If the VideoPlayer object has the scaleMode property set to VideoScaleMode.MAINTAIN_ASPECT_RATIO or VideoScaleMode.NO_SCALE, then this value is used and the resizing happens instantly, rather than waiting.

The time in milliseconds after which attempts to make a connection stop.

Related API Elements

The VideoPlayer object that owns this object.

Related API Elements

Creates a new NCManager instance.

Closes the NetConnection.

Related API Elements

Called by the VideoPlayer object if the connection is successfully made but the stream is not found. If multiple alternate interpretations of the RTMP URL are possible, it tries to connect to the server with a different URL and hand back a different stream name.

This can be necessary in cases where the URL is something like rtmp://servername/path1/path2/path3. When passing in an application name and an instance name, open the NetConnection object with rtmp://servername/path1/path2, or use the default instance so the stream is opened with path2/path3. In general, this is possible whenever there are more than two parts to the path but not possible if there are only two (there should never be only one).

Related API Elements

Called by the VideoPlayer object to ask for a connection to the URL. Once a connection is successful or failed, then call the VideoPlayer.ncConnected() method. If the connection has failed, then set nc = null before calling.

Parameters

Related API Elements

Allows getting of the fallbackServerName, fpadZone, objectEncoding, and proxyType properties. See setProperty() for an explanation of these properties.

Parameters

Related API Elements

Called by any helper object doing a task for the NCManager object to signal it has completed and whether it was successful. The NCManager object uses this with SMILManager.

Parameters

Related API Elements

Called by the VideoPlayer object to ask for reconnection after the connection is lost. Once the connection is either successful or failed, call the VideoPlayer.ncReconnected() method. If the connection failed, set nc = null before calling.

Related API Elements

Allows setting of the fallbackServerName, fpadZone, objectEncoding, and proxyType properties.

The fallbackServerName property specifies a Flash Media Server (FMS) URL to be used if the primary server address derived from the URL passed into connectToURL() cannot be reached. This property can also be set directly through the fallbackServerName property.

The fpadZone property specifies the fpadZone property for Flash Media Server (FMS). If the returned value is not a number (NaN), then no zone is set. The fpadZone property must be set before the connection process begins to have effect. If you do not want to set a zone, set the fpadZone property to NaN.

The objectEncoding property specifies the value to be used for the objectEncoding property on NetConnection instances. Default is flash.net.ObjectEncoding.AMF0.

The proxyType property specifies the value to be used for the proxyType property on NetConnection instances. Default is "best".

Parameters

The default timeout in milliseconds.

Related API Elements

State variable indicating the short version number of the component. The version number is useful when you have a FLA file and need to know the component version. To determine the component version, type the following code trace into the FLA file:

FLVPlayback.SHORT_VERSION

The SHORT_VERSION variable includes only the major and minor version numbers, for example, 2.0. The VERSION variable includes the major and minor version numbers as well as the revision and build numbers, for example, 2.0.0.11.

State variable indicating the long version number of the component. The version number is useful when you have a FLA file and need to know the component version. To determine the component version, type the following code trace into the FLA file:

FLVPlayback.VERSION

The VERSION variable includes the major and minor version numbers as well as the revision and build numbers, for example, 2.0.0.11. The SHORT_VERSION variable includes only the major and minor version numbers, for example, 2.0.

To run the example, follow these steps:

1. Add the FLVPlayback component in the library.
2. Replace testVideoPath with an absolute or relative path to an FLV file.
3. Save this code as NCManagerExample.as in the same directory as your FLA file.
4. Set the Document class in the FLA file to NCManagerExample.
