autoSize Boolean value that, if true, resizes the component at runtime to use the source FLV dimensions. The

default value is

false.

Note: The encoded frame size of the FLV is not the same as the default dimensions of the FLVPlayback component.

bufferTime Number of seconds to buffer before beginning playback. The default value is 0.

contentPath String that specifies the URL to an FLV or to an XML file that describes how to play the FLV. Double-

clicktheValuecellforthisparametertoactivatetheContentPathdialogbox.Thedefaultisanemptystring.Ifyou

do not specify a value for the

contentPath parameter, nothing happens when Flash executes the FLVPlayback

instance.

isLive Boolean value that, if true, specifies that the FLV is streaming live from FMS. The default value is false.

cuePoints A string that specifies the cue points for the FLV. Cue points allow you to synchronize specific points in

the FLV with Flash animation, graphics, or text. The default value is an empty string.

maintainAspectRatio A Boolean value that, if true, resizes the video player in the FLVPlayback component to retain

thesourceFLVaspectratio;thesourceFLVisstillscaledandtheFLVPlaybackcomponentitselfisnotresized.The

autoSize parameter takes precedence over this parameter. The default value is true.

skin A parameter that opens the Select Skin dialog box and allows you to choose a skin for the component. The

default value is None. If you choose None, the FLVPlayback instance does not have control elements that allow the

usertoplay,stop,orrewindtheFLV,ortakeotheractionsthatthecontrolsmakepossible.Ifthe

autoPlay parameter

is set to true, the FLV plays automatically. For more information, see “Customizing the FLVPlayback component” in

Using ActionScript 3.0 Components or ActionScript 2.0 Components Language Reference.

totalTime Total number of seconds in the source FLV. The default value is 0. If you use progressive download, Flash

uses this number if it is set to a value greater than zero (0). Otherwise, Flash tries to take the time from metadata.

Note: If you’re using FMS or FVSS, this value is ignored; the total time of the FLV is taken from the server.

volume A number from 0 to 100 that represents the percentage of maximum volume at which to set the volume.

Specify the contentPath parameter

If you imported a local video clip into Flash for use with progressively downloaded or streaming video content,

update the

contentPath parameter of the FLVPlayback component before uploading your content to a web server.

The

contentPath parameter specifies the name and location of the FLV on the server, and implies the playback

method (for example, progressively download using HTTP, or streaming from Flash Media Server using RTMP).

1 With the component selected, open the Property inspector (Window > Properties > Properties) and select Param-

eters in the Property inspector, or open the Component inspector (Window > Component Inspector).

2 Enter values for parameters, or use the default settings as appropriate. For the contentPath parameter, do the

following:

a Double-click the Value cell for the contentPath parameter to activate the Content Path dialog box.

b Enter the URL or local path to either the FLV file or the XML file (for Flash Media Server or FVSS) that describes

how to play the FLV.

If you do not know the location of the FLV or XML file, click the folder icon to navigate to the correct location. When

browsing for an FLV file, if it is at or below the location of the target SWF file, Flash automatically makes the path

relative to that location so that it is ready for serving from a web server. Otherwise, it is an absolute Windows or

Macintosh file path.
