ActionScript 2.0 Language Reference - Adobe Help and Support

Generally if you want your code to respond to a specific cue point at the time it occurs you
should use the onCuePoint() event handler to trigger some action in your code.
You can use the list of cue points provided to the onMetaData() event handler to let your user
start playing the video at predefined points along the video stream. Pass the value of the cue
point's time property to the NetStream.seek() method to play the video from that cue
point.

Parameters
infoObject:Object - An object containing the name, time, type, and parameters for the
cue point.
Example
The code in this example starts by creating new NetConnection and NetStream objects. Then
it defines the onCuePoint() handler for the NetStream object. The handler cycles through
each named property in the infoObject object and prints the property's name and value.
When it finds the property named parameters it cycles through each parameter name in the
list and prints the parameter name and value.
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
ns.onCuePoint = function(infoObject:Object)
{
trace("onCuePoint:");
for (var propName:String in infoObject) {
if (propName != "parameters")
{
trace(propName + " = " + infoObject[propName]);
}
else
{
trace("parameters =");
if (infoObject.parameters != undefined) {
for (var paramName:String in infoObject.parameters)
{
trace(" " + paramName + ": " +
infoObject.parameters[paramName]);
}
}
else
{
trace("undefined");
}
