660 FLVPlayback Component (Flash Professional Only)

For several reasons, the playheadTime property might not have the expected value

immediately after calling one of the seek methods or setting

playheadTime to cause seeking.

First, for a progressive download, you can seek only to a keyframe, so a seek takes you to the

time of the first keyframe after the specified time. (When streaming, a seek always goes to the

precise specified time even if the source FLV file doesn’t have a keyframe there.) Second,

seeking is asynchronous, so if you call a seek method or set the

playheadTime property,

playheadTime does not update immediately. To obtain the time after the seek is complete,

listen for the

seek event, which does not start until the playheadTime property has updated.

Example

The following example disables the FLV file from playing automatically, calls the

seekSeconds() method to set the playhead 5 seconds into the video, and begins playing the

FLV file at that point.

Drag an FLVPlayback component to the Stage, and give it an instance name of

my_FLVPlybk. Then add the following code to the Actions panel on Frame 1 of the

Timeline:

/**

Requires:

- FLVPlayback component on the Stage with an instance name of my_FLVPlybk

import mx.video.*;

my_FLVPlybk.autoPlay = false;

my_FLVPlybk.contentPath = "http://www.helpexamples.com/flash/video/

water.flv";

var listenerObject:Object = new Object();

listenerObject.ready = function(eventObject:Object) {

my_FLVPlybk.seekSeconds(4);

my_FLVPlybk.play();

}

my_FLVPlybk.addEventListener("ready", listenerObject);
