Actionscript problem with resizing video object resolution

[FredT]

Hi,

I have a problem with my AS3 code. The user can type their desired width and height for the video in two boxes and hit a button that triggers the updateResolution function. Everything works except for when I redeclare video = new Video() in the updateResolution function, the variables that the user set don't register. If I manually say:

video = new Video(1024,768);

it works fine, but for some reason the vars don't have the same effect...

video = new Video(setWidth, setHeight);

Does anyone have any suggestions? Thanks!!!

//Initial vars for resolution
var setWidth:int = 800;
var setHeight:int = 600;
 
//Display the webcam feed on the screen
var cam:Camera = Camera.getCamera();
var video:Video = new Video(800, 600);
video.width = 320; //Changing it on the screen only so it fits
video.height = 240; //The actual resolution remains 800x600
cam.setMode(800, 600, 15, true);
video.attachCamera(cam);
stage.addChild(video);
video.x = 320;
 
//updateRes is my button, of course
updateRes.addEventListener(MouseEvent.MOUSE_DOWN, updateResolution);
 
function updateResolution(e:MouseEvent):void{
	setWidth = Number(userWidth.text); //userWidth and userHeight are the text inputs
	setHeight = Number(userHeight.text);
	cam.setMode(setWidth, setHeight, 15, true); //This works fine with the setWidth/setHeight vars
	stage.removeChild(video);
	video = new Video(setWidth, setHeight); //This does not
	video.width = 320;
	video.height = 240;
	video.attachCamera(cam);
	stage.addChild(video);
	video.x = 320;
}

	video = new Video(setWidth, setHeight); //This does not
	video.width = 320;
	video.height = 240;

Aren't the second two lines undoing the first line?

No, because they just change the display size of the video, while the actual resolution (which is actually shown more later when the app takes a snapshot from the webcam) remains.

Does that make sense?
