ActionScript 2.0 Language Reference - Adobe Help and Support

Use of a deblocking filter has an effect on overall playback performance, and it is usually not
necessary for high-bandwidth video. If your system is not powerful enough, you may
experience difficulties playing back video with this filter enabled.
Availability: ActionScript 1.0; Flash Player 6
Example
The following example plays video1.flv in the my_video video object, and lets the user change
the deblocking filter behavior on video1.flv. Add a video object called my_video and a
ComboBox instance called deblocking_cb to your file, and then add the following
ActionScript to your FLA or AS file.
var deblocking_cb:mx.controls.ComboBox;
var my_video:Video; // my_video is a Video object on the Stage
var my_nc:NetConnection = new NetConnection();
my_nc.connect(null);
var my_ns:NetStream = new NetStream(my_nc);
my_video.attachVideo(my_ns);
my_ns.play("video1.flv");
deblocking_cb.addItem({data:0, label:'Auto'});
deblocking_cb.addItem({data:1, label:'No'});
deblocking_cb.addItem({data:2, label:'Yes'});
var cbListener:Object = new Object();
cbListener.change = function(evt:Object) {
my_video.deblocking = evt.target.selectedItem.data;
};
deblocking_cb.addEventListener("change", cbListener);
Use the ComboBox instance to change the deblocking filter behavior on video1.flv.
