Subject [jira] [Commented] (FLEX-33926) Null error in videoDisplay.videoObject while using VideoDisplay
Date Wed, 04 Dec 2013 19:08:36 GMT

    [ https://issues.apache.org/jira/browse/FLEX-33926?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13839217#comment-13839217

OmPrakash Muppirala commented on FLEX-33926:
--------------------------------------------

The new APIs in OSMF 2.0 has moved things around a bit.  

In OSMF 1.x
MediaPlayer.videoObject returned a Video object.  So, calling spark.components.VideoDisplay.videoObject()
used to return a Video object to which we could attach a camera.  

In OSMF 2.0,
MediaPlayer.videObject returns a VideoSurface object which has a internal Video object.  Making
this a public property, I was able to fix this bug:

Now, spark.components.VideoDisplay.videoObject() should look like this:
    public function get videoObject():Video
    {
	var videoSurface:VideoSurface = videoPlayer.displayObject as VideoSurface;
        return videoSurface.video;
    }

Unfortunately, to make this work, OSMF team needs to make the video object in VideoSurface
public.  

I have created a ticket for this in OSMF bugbase https://bugbase.adobe.com/index.cfm?event=bug&id=3679507

Please vote on that ticket to have it resolved.  Once that is done, we can fix the Apache
Flex codebase.
