Add ActionScript cue points

You can add ActionScript cue points to an FLV file using the addASCuePoint() method. The following example adds two ActionScript cue points to the FLV file when it is ready to play. It adds the first cue point using a cue point object, which specifies the time, name, and type of the cue point in its properties. The second call specifies the time and name using the method’s time and name parameters.

// Requires an FLVPlayback instance called my_FLVPlybk on Stage 
import fl.video.*; 
import fl.video.MetadataEvent; 
my_FLVPlybk.source = "http://www.helpexamples.com/flash/video/cuepoints.flv" 
var cuePt:Object = new Object(); //create cue point object 
cuePt.time = 2.02; 
cuePt.name = "ASpt1"; 
cuePt.type = "actionscript"; 
my_FLVPlybk.addASCuePoint(cuePt);//add AS cue point 
// add 2nd AS cue point using time and name parameters 
my_FLVPlybk.addASCuePoint(5, "ASpt2"); 

For more information, see the FLVPlayback.addASCuePoint() method in the ActionScript 3.0 Language and Components Reference.

Listen for cuePoint events

The cuePoint event allows you to receive control in your ActionScript code when a cuePoint event occurs. When cue points occur in the following example, the cuePoint listener calls an event handler function that displays the value of the playheadTime property and the name and type of the cue point. Use this example in combination with the example in the preceding section, Add ActionScript cue points, to see the results.

my_FLVPlybk.addEventListener(MetadataEvent.CUE_POINT, cp_listener); 
function cp_listener(eventObject:MetadataEvent):void { 
        trace("Elapsed time in seconds: " + my_FLVPlybk.playheadTime); 
        trace("Cue point name is: " + eventObject.info.name); 
        trace("Cue point type is: " + eventObject.info.type); 
}

For more information on the cuePoint event, see the FLVPlayback.cuePoint event in the ActionScript 3.0 Language and Components Reference.

Find cue points

Using ActionScript, you can find a cue point of any type, find the nearest cue point to a time, or find the next cue point with a specific name.

The ready_listener() event handler in the following example calls the findCuePoint() method to find the cue point ASpt1 and then calls the findNearestCuePoint() method to find the navigation cue point that is nearest to the time of cue point ASpt1:

import fl.video.FLVPlayback; 
import fl.video.CuePointType; 
import fl.video.VideoEvent; 
my_FLVPlybk.source = "http://www.helpexamples.com/flash/video/cuepoints.flv" 
var rtn_obj:Object; //create cue point object 
my_FLVPlybk.addASCuePoint(2.02, "ASpt1");//add AS cue point 
function ready_listener(eventObject:VideoEvent):void { 
    rtn_obj = my_FLVPlybk.findCuePoint("ASpt1", CuePointType.ACTIONSCRIPT); 
    traceit(rtn_obj); 
    rtn_obj = my_FLVPlybk.findNearestCuePoint(rtn_obj.time, CuePointType.NAVIGATION); 
    traceit(rtn_obj); 
} 
my_FLVPlybk.addEventListener(VideoEvent.READY, ready_listener); 
function traceit(cuePoint:Object):void { 
    trace("Cue point name is: " + cuePoint.name); 
    trace("Cue point time is: " + cuePoint.time); 
    trace("Cue point type is: " + cuePoint.type); 
}

In the following example, the ready_listener() event handler finds cue point ASpt and calls the findNextCuePointWithName() method to find the next cue point with the same name:

import fl.video.*; 
my_FLVPlybk.source = "http://www.helpexamples.com/flash/video/cuepoints.flv" 
var rtn_obj:Object; //create cue point object 
my_FLVPlybk.addASCuePoint(2.02, "ASpt");//add AS cue point 
my_FLVPlybk.addASCuePoint(3.4, "ASpt");//add 2nd Aspt 
my_FLVPlybk.addEventListener(VideoEvent.READY, ready_listener); 
function ready_listener(eventObject:VideoEvent):void { 
    rtn_obj = my_FLVPlybk.findCuePoint("ASpt", CuePointType.ACTIONSCRIPT); 
    traceit(rtn_obj); 
    rtn_obj = my_FLVPlybk.findNextCuePointWithName(rtn_obj); 
    traceit(rtn_obj); 
} 
function traceit(cuePoint:Object):void { 
    trace("Cue point name is: " + cuePoint.name); 
    trace("Cue point time is: " + cuePoint.time); 
    trace("Cue point type is: " + cuePoint.type); 
}

For more information about finding cue points, see the FLVPlayback.findCuePoint(), FLVPlayback.findNearestCuePoint(), and FLVPlayback.findNextCuePointWithName() methods in the ActionScript 3.0 Language and Components Reference.

Seek navigation cue points

You can seek a navigation cue point, seek the next navigation cue point from a specified time, and seek the previous navigation cue point from a specified time. The following example plays the FLV file cuepoints.flv and seeks the cue point at 7.748 when the ready event occurs. When the cuePoint event occurs, the example calls the seekToPrevNavCuePoint() method to seek the first cue point. When that cuePoint event occurs, the example calls the seekToNextNavCuePoint() method to seek the last cue point by adding 10 seconds to eventObject.info.time, which is the time of the current cue point.

import fl.video.*; 
 
my_FLVPlybk.addEventListener(VideoEvent.READY, ready_listener); 
function ready_listener(eventObject:Object):void { 
    my_FLVPlybk.seekToNavCuePoint("point2"); 
} 
my_FLVPlybk.addEventListener(MetadataEvent.CUE_POINT, cp_listener); 
function cp_listener(eventObject:MetadataEvent):void { 
    trace(eventObject.info.time); 
    if(eventObject.info.time == 7.748) 
        my_FLVPlybk.seekToPrevNavCuePoint(eventObject.info.time - .005); 
    else 
        my_FLVPlybk.seekToNextNavCuePoint(eventObject.info.time + 10); 
} 
my_FLVPlybk.source = "http://helpexamples.com/flash/video/cuepoints.flv";

For more information, see the FLVPlayback.seekToNavCuePoint(), FLVPlayback.seekToNextNavCuePoint(), and FLVPlayback.seekToPrevNavCuePoint() methods in the ActionScript 3.0 Language and Components Reference.

Enable and disable embedded FLV file cue points

You can enable and disable embedded FLV file cue points using the setFLVCuePointEnabled() method. Disabled cue points do not trigger cuePoint events and do not work with the seekToCuePoint(), seekToNextNavCuePoint(), or seekToPrevNavCuePoint() methods. You can find disabled cue points, however, with the findCuePoint(), findNearestCuePoint(), and findNextCuePointWithName() methods.

You can test whether an embedded FLV file cue point is enabled using the isFLVCuePointEnabled() method. The following example disables the embedded cue points point2 and point3 when the video is ready to play. When the first cuePoint event occurs, however, the event handler tests to see whether cue point point3 is disabled and, if so, enables it.

import fl.video.*; 
my_FLVPlybk.source = "http://www.helpexamples.com/flash/video/cuepoints.flv"; 
my_FLVPlybk.addEventListener(VideoEvent.READY, ready_listener); 
function ready_listener(eventObject:VideoEvent):void { 
    my_FLVPlybk.setFLVCuePointEnabled(false, "point2"); 
    my_FLVPlybk.setFLVCuePointEnabled(false, "point3"); 
} 
my_FLVPlybk.addEventListener(MetadataEvent.CUE_POINT, cp_listener); 
function cp_listener(eventObject:MetadataEvent):void { 
        trace("Cue point time is: " + eventObject.info.time); 
        trace("Cue point name is: " + eventObject.info.name); 
        trace("Cue point type is: " + eventObject.info.type); 
        if (my_FLVPlybk.isFLVCuePointEnabled("point2") == false) { 
            my_FLVPlybk.setFLVCuePointEnabled(true, "point2"); 
        } 
}

For more information, see the FLVPlayback.isFLVCuePointEnabled() and FLVPlayback.setFLVCuePointEnabled()methods in the ActionScript 3.0 Language and Components Reference.

Remove an ActionScript cue point

You can remove an ActionScript cue point using the removeASCuePoint() method. The following example removes the cue point ASpt2 when cue point ASpt1 occurs:

import fl.video.*; 
my_FLVPlybk.source = "http://www.helpexamples.com/flash/video/cuepoints.flv" 
my_FLVPlybk.addASCuePoint(2.02, "ASpt1");//add AS cue point 
my_FLVPlybk.addASCuePoint(3.4, "ASpt2");//add 2nd Aspt 
my_FLVPlybk.addEventListener(MetadataEvent.CUE_POINT, cp_listener); 
function cp_listener(eventObject:MetadataEvent):void { 
        trace("Cue point name is: " + eventObject.info.name); 
        if (eventObject.info.name == "ASpt1") { 
            my_FLVPlybk.removeASCuePoint("ASpt2");     
            trace("Removed cue point ASpt2"); 
        } 
}

For more information, see FLVPlayback.removeASCuePoint() in the ActionScript 3.0 Language and Components Reference.
