Demonstrates how frames from a loaded video can be drawn into bitmap data
so that visual effects may be applied.
public class @ax-graphic-flex-image-effects-10-Flex-VideoFilters extends Sprite {
public var _video:graphic_flex_image_effects_10_Flex_VideoLoader;
public var _filteredScreen:Bitmap;
Constructor. Instantiates VideoLoader to load video, creates a bitmap/bitmap data
to display the video's frames and sets up a listener to know when the video frame changes.
public function @ax-graphic-flex-image-effects-10-Flex-VideoFilters() {
_video = new graphic_flex_image_effects_10_Flex_VideoLoader(400, 225, "graphic-flex-image-effects-10-assets-road.flv");
_video.addEventListener(Event.RENDER, onVideoRender);
addChild(_video);
_filteredScreen = new Bitmap();
_filteredScreen.y = _video.height;
addChild(_filteredScreen);
}
Handler for when the video frame updates. This draws the current video frame into the
bitmap data and applies an image effect.
parameter: event Event dispatched by VideoLoader.
private function onVideoRender(event:Event):void {
var bitmapData:BitmapData = new BitmapData(_video.width, _video.height);
// draws video frame into bitmap data, making sure it is at proper scale
var matrix:Matrix = new Matrix();
matrix.scale(_video.scaleX, _video.scaleY);
bitmapData.draw(_video, matrix);
// comment/uncomment these lines to see different effects applied
//new BlurEffect(5, 5, 1, BlendMode.SCREEN).apply(bitmapData);
//new GridEffect(3, 3).apply(bitmapData);
