ActionScript 3.0 :: Component With Live Preview?
Feb 18, 2009
There seems to be very little information on developing a custom component with live preview.So far i've created a swf whose application class extends UIComponent.I've also created a custom component.Then I've added the Live Preview field in the custom component's Component Definition.What I would like to do now is reposition elements within the preview swf when the user resizes the component.
To do this i need to know two things - 1 what event to listen for when the user resizes the component, and 2 the current dimensions of the resized component.
1. My only success was that ComponentEvent.SHOW seems to dispatch when the user resizes the component. (i had no luck with any of the RESIZE events - Event.RESIZE etc)
2. However the width/height properties don't seem to change on resize, they stay at the original dimensions of the component.

I've created a class in AS3 which I've linked to a component in Flash CS5 and exported as a SWC. That SWC is then loaded into my main flash file and used inside some movieclips. The issue is that I want some code in the class to be used when using the component in Flash CS5 (for previewing purposes) and some code to only be used when running the main swf. Is there any way to detect when the class is being used in Flash CS5 vs being used when running the swf?

I'm having a problem with component live previews. If I just create a movie clip and set the live preview, all instances of the clip i put on stage update separatly from each other (their live preview that is). As soon as I change the clip to a component (export .swc or compiled clip) all the instances update together. eg if i set the component parameter 'title' - all titles of the all the instances on the stage will change. This didn't happen when it was just a movieclip - all instances changed separatly as i set them.

I've created a swf for a component live preview. The live preview appears to work ok when creating a new component, and setting the live preview in the component definition panel.
When I update an existing component definition (in a separate component library FLA) the live preview does not work. The strange thing is if I copy the entire (component FLA) library and paste it into a new FLA it works fine (although in doing so I receive a whole bunch of errors in the output window saying - Plugin tool script error in method ik_isIKContainer).

I am working with an AS2 application that was put together a while back. The app is used to publish a live video stream to FMS. I am using the Camera class to connect to a local camera (Camera.get()) and to setup the encoding specs for the stream that is to be published to FMS. To preview the camera signal, I am using Video.attachVideo() to attach that camera output to a Video instance on the stage. This is all working greta for me. But here's the thing. The video stream that is being pumped to the Video instance is the direct signal from the camera. Nice and clean. I seem to remember that there is a way to view the video signal with the encoding settings applied to it. It's just one little line of code, if I remember correctly. However, I can't seem to find the code that will do that.
Can anyone quickly share the code that will allow me to preview the encoded video stream?

I have a project with a bunch of movie clips. Each movie clip has it's own animation. The problem is I can't see the movie clips on the stage, I have to test the movie. Live preview is checked, but greyed out. Is there anyway to live preview working on main stage?

I want to develop custom components (that show up in the Components panel) which a Flash designer can drag onto the stage and use the Component Inspector to customize it to their liking (inspectable parameters, I believe they are called). I'd also ideally like to implement a Live Preview so they can see their adjustments live on the design stage.
Does anyone know a good resource for learning the correct way to do this? I've found one that used to work in CS3 but now that I am on CS5 it isn't happening for me: [URL]. There's also the "official" Adobe blog post, I think the previously mentioned article gives it an appropriate shout-out for being "long and cumbersome". It seems that this should be a pretty popular technique.

I have FLV video component waiting for the user to push play. However, I want a thumbnails that I can stick in there because it is just black. How does this work with the FLV playback component? I can't find anything about this.

i am trying to get a preview image to appear when using the flvplayback component. it does not show up within the flash player or when i test on a server. i was able to use the component inspector to find the image i wanted and export and save it. i saved the png file in the same directory where my flv is located. here is my AS:
Code: Select allimport fl.video.FLVPlayback;
var flv_video_mc:FLVPlayback = new FLVPlayback();
flv_video_mc.source = "flv/video.flv";
flv_video_mc.preview = "flv/video_preview.png";

Does anyone know what criterea Flash uses for discovering the Live Preview class for a Component? Background We are attempting to automate the creation of a SWC that contains a component to be used from Flash. We are able to make it visible to flash by modifying the manifest.xml and wiring up the component definitions. However, the component cannot be dragged onto the stage (or library), presumably because it has no form of LivePreview. To give better clarification of where we are coming from, we've noticed the following in SWCs exported from Flash (using swfdump):
fl.livepreview.LivePreviewParent contains the same mod attribute as the visual component in the manifest.xml file fl.livepreview.LivePreviewParent is exported as a symbol The short-named component (ie. no package, referenced in the components definition in the manifest.xml) is exported as a symbol However, I can see no other differences between that and the SWC from Flex. We can obviously use JSFL to perform the task, but we'd rather not install Flash on the build server.

I've been customizing the flvplayback component and have run into a problem. So far I have successfully created a custom skin for the flvplayback component, with a play overlay button,which loads the FLV dynamically from flashvars.I am now trying to load in a static image which appears until the video is played.I've been looking around the internet and in the Adobe forums, but haven't found what I'm looking for.I thought perhaps the Preview min the AS3 flvplayback component would help, but this won't work apparently.
I was thinking myPlayer.source = "image.jpg"; but then how can I change what the source is once someone clicks on the video? I also found fl.video.VideoEvent, but I'm not sure how I can use this to set the image as the source, until someone presses the play button, or until the video is playing (note that I am using an overlay play button which shows up whenever the movie is paused, so once the video starts playing, I would not want the static preview image to come up again...just until someone clicks the any play
button).

I have found something good here. [URL]..The mouseover effect on the list item is good. Any ideas to make this look.. I can infer that this is happening on mouseover of the Image Component. I think this is similar to google image search preview of images. If anyone have come across a component similar to this kindly share it to me and to all.

I'm having some trouble with getURL (I think). It works fine when I preview with Flash's html preview but it's not working on my server. It's pretty simple. [URL].selected1 is a user-defined variable pointing to a page: ie, when the user selects variable page1 the page to be opened is [URL]. Like I said, it works with Flash's preview, but not on my server(no 404 or any response). Does there seem to be a problem with my code or might I be overlooking a server error? Here's my code:

I can play my live rtmp (fms) stream through the FLVPlayback component without any problems. I even figured out how to make my own player in AS2. But I still can not get a LIVE player in AS3. I keep getting "onMetaData", "Async" and "onBWDone" errors in varying combinations.Can someone, please find it in their heart to provide me with the appropriate code? Every single tutorial online is either AS2 or is for flvplayback (nc.connect goes to null).[code]

In order to play a FMS stream (live or on demand), either an FLVPlayback component or the Video class is needed.And they require ActionScript 3 and Flash 8 or above.
As far as i know , Youtube, Dailymotion and Google Video stream their on demand videos from a FMS, and their players are compatible with Flash 7.
How can they achieve this? If Youtube, Google and Dailymotion do that, i deduce it's possible..
I tried to create a Flash 7 application that plays a video coming from FMS, using a MediaDisplay component, but it doesn't work well. Sometimes it shows the video, sometimes not.So i don't think youtube player uses MediaDisplay..

I am passing to the source property of a VideoDisplay component a DynamicStreamingVideoSource object with 3 different dynamic live stream items, described by this XML, for your consideration:
src="rtmp://88.87.56.214:1935/live/fashiontv_tmo_h.stream" bitrate="19200"
src="rtmp://88.87.56.214:1935/live/fashiontv_tmo_m.stream" bitrate="9000"
src="rtmp://88.87.56.214:1935/live/fashiontv_tmo_l.stream" bitrate="3600"
But the player then runs the stream with the lowest bitrate, out of those 3. Wasn't it supposed to go for the stream with the highest bitrate, that is viewable by the end-user? All 3 streams have been individually tested and they are all viewable.

I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?

So I have a still image covering a video so that when it's pressed it disappears and the video plays. I get no errors for the code I'm using, but when I preview my site nothing happens when I click the image.
The code I'm using is:
import fl.video.VideoEvent;function doPlayVid(e:MouseEvent):void {tanmov.play();tanbtn.visible = false;}function doStopped(e:VideoEvent):void {tanbtn.visible = true;}tanbtn.addEventListener(MouseEvent.CLICK,doPlayVid );tanmov.addEventListener(VideoEvent.STOPPED_STATE_ENTERED,doStopped);

My searches have led me into some overcomplicated solutions. I'm using Flash to create a simple .swf that contains a movie with subtitles. I'm sure there are better ways but this is the easiest and I have been too long gone from developing in Flash and uBer rusty.
I used the movie importer, added captions exported my movie. All works great. The movie is set to NOT auto-play though and fades in from black so when the user first sees it they just see the skin and a black box. What I would like to do is have a preview image appear instead of the black first frame until the user plays the movie.

I've been coming across this weird issue while creating a website menu: Sometimes, when I preview/export my SWF, some of my objects (text, graphics) will shift a few pixels on mouse over/mouse out - but when I look through all my frames in the timeline (and watch closely), there is no such shift. Has anyone else experienced this? Sometimes it will only do it when looking at the SWF locally, with flash player, but when viewing in a browser, it goes away. Of course, this is only sometimes - it has showed up in the browser as well. I've tried saving first, restarting flash, force refreshing the browser, etc, etc...it seems quite erratic.
