NCManager

Kind of class:class
Inherits from:none
Implements:
Classpath:mx.video.NCManager
File last modified:Tuesday, 18 December 2007, 16:08:42

Creates NetConnection for VideoPlayer, a
helper class for that user facing class.

NCManager supports a subset of SMIL to handle multiple streams
for multiple bandwidths. NCManager assumes any URL that does not
begin with "rtmp://", does not end with ".flv" and does not
have any parameters is a SMIL url. See SMILParser for more on SMIL
support.

fallbackServerName

fallbackServerName:String
(read)

fallbackServerName is exposed in two ways:

User can supply second in smil and that base
attr will be taken as the fallbackServerName (note that only
the server name will be taken from this and not the application
name or anything else).

The second way is the user can directly set this by
accessing the ncMgr property in FLVPlayback or VideoPlayer and
set fallbackServerName property directly.

fpadZone

fpadZone:Number

Class methods

stripFrontAndBackWhiteSpace

static private function stripFrontAndBackWhiteSpace (
p_str:String) : String

Instance methods

_onFCSConnectTimeOut

public function _onFCSConnectTimeOut (
) : Void

Called on interval to timeout all connection attempts.

For creating rtmp connections.

See also:

bitrateMatch

private function bitrateMatch (
) : Void

matches bitrate with stream

canReuseOldConnection

private function canReuseOldConnection (
parseResults:Object) : Boolean

Compares connection info with previous NetConnection,
will reuse existing connection if possible.

cleanConns

public function cleanConns (
)

Stops all intervals, closes all unneeded connections, and other
cleanup related to the connectRTMP strategy of
pipelining connection attempts to different protocols and
ports.

For creating rtmp connections.

See also:

close

function close (
) : Void

Specified by:

connectAgain

function connectAgain (
) : Boolean

See also:
Returns:
  • true if will attempt to make another connection,
    false if already made attempt or no additional attempts
    are merited.
    #
Specified by:

connectFPAD

private function connectFPAD (
url:String) : Boolean

Top level function for downloading fpad XML from FMS 2.0
server. Creates and kicks off a FPADManager instance
which does all the work.

connectHTTP

private function connectHTTP (
) : Boolean

Handles creating NetConnection instance for
progressive download of FLV via http.

connectOnStatus

public function connectOnStatus (
target:NetConnection, info:Object) : Void

netStatus event listener when connecting

connectRTMP

private function connectRTMP (
) : Boolean

Top level function for creating NetConnectioninstance for streaming playback of FLV via rtmp. Actually
tries to create several different connections using different
protocols and ports in a pipeline, so multiple connection
attempts may be occurring simultaneously, and will use the
first one that connects successfully.

connectToURL

function connectToURL (
url:String) : Boolean

See also:
Returns:
  • true if connection made synchronously, false attempt
    made asynchronously so caller should expect a "connected"
    event coming.
    #
Specified by:

disconnectOnStatus

public function disconnectOnStatus (
target:NetConnection, info:Object) : Void

netStatus event listener for disconnecting extra
NetConnections that were opened in parallel

getBitrate

function getBitrate (
) : Number

For RTMP streams, returns value calculated from autodetection,
not value set via setBitrate().

parseURL

private function parseURL (
url:String) : Object

Parses URL to determine if it is http or rtmp. If it is rtmp,
breaks it into pieces to extract server URL and port, application
name and stream name. If .flv is at the end of an rtmp URL, it
will be stripped off.
