Hi Jerome.

Thanx for the idea, but in my code don´t work and I don´t now why.

My code is this

private function catchCam():void{


		 	this._vid=new Video();

	 		this._vid.width=320;

	 		this._vid.height=240;
	 		this.vd_Cam.addChild(this._vid);

	 		this.cam=Camera.getCamera(this.cbCam.selectedIndex.toString());

if (!this.cam) { this._vid.attachCamera(null); this._vid.clear(); }else{ this._vid.attachCamera(this.cam); } }

note: vd_Cam it´s a videoDisplay Object.

The problem is that when execute
this._vid.attachCamera(null);
this._vid.clear();

The camera never deatach of the videoDisplay Object and never clear the videoDisplay Object. By the way debugging the code i´m sure that this sentences are executed.

Why is this happening to me?, any idea?

Thanx

Why don’t extend a UIComponent class to create a custom Video Component .. According to my personal opinion VideoDisplay component of Flex 3.5 sucks .

ok nevermind I got clear() working. I had to use .clear() on the Video object that was attached to the VideoDisplay

setting a null source does not seem to have any effect either. I’m using a Video attached to a VideoDisplay (something like VideoDisplay.addChild(Video)

@jerome,

If clear() doesn’t work, maybe try setting a null source.

Anyone know how to clear a videoDisplay that has been showing a live stream? .pause() does not seem to have any effect

This tip is not working perfectly, I recommend instead, in order to clear the video, to use the visible property (with a Fade effect is terrible!).

Moreover, use mx_internal stuff is not recommended since it can be remove for future versions of the framework.

Hi Peter,

Sorry, some of my code did not appear properly because of the tags:

UploadVideo.as
public var videoName:String;
public var video:ByteArray;

videosOfStudents = ArrayCollection() // of UploadVideo objects
mx:List id=”cntlMovie” dataProvider=”{modelLocator.videosOfStudents}” width=”300″

mx:VideoDisplay id=”cntlDisp” source=”{cntlMovie.selectedItem.videoName}” width=”100%” height=”100%”

The output I get is:
(TypeError)#0
errorID = 1009
message = “Error #1009: Cannot access a property or method of a null object reference.”

Thanks again.

Vardan
