ActionScript 3.0 :: Clearing Locally Loaded Video From Memory?
Mar 4, 2011
I'm using the code below for loading my flvs. What kind of function and parameters are needed to make sure the video is cleared from memory? In order to stop the sound, I'm using SounMixer.stopAll() which works fine to stop the sound, but when I unload the video and stop the sound, I can see that memory is still being consumed. I've been reading about nulling a netstream, but since I'm loading my flvs locally for this project, how do you ensure that the video is fully unloaded from memory when not using a netstream?This example dynamically creates an FLVPlayback instance. To run the example, follow these steps.
1.Place the FLVPlayback component on the Stage at 0,0 and provide the instance name player.2.Replace videoPath with an absolute or relative path to an FLV file.3.Save this code as FLVPlaybackExample.as in the same directory as your FLA file.4.Set the Document class in the FLA file to FLVPlaybackExample.
package
{
import fl.video.FLVPlayback;

Why does my swf's skin referenced by a simple component FLA work locally but NOT live? There's no AS3 in the component FLA. It's just a one-layer component referenced to the the FLV. When I test locally, IN FLASH CS4 ONLY, and click on "Animalia - Verse From the Zoo" the FLV and skin load and the video (source FLV - "Sequence01.flv") plays. But the same thing live only loads the swf for the FLV file area but NO SKIN. Try it yourself, please:Has anyone had this problem and knows the solution? All files are in the SAME FOLDER on the web server. I've tried every URL and path combination I can think of on the website. I've tried referencing the whole URL.
Yet whatever path combination I try, either nothing happens, or I just get the FLV box but no skin. Which is what's happening now. Publish settings are set to Flash Player 10 for all files. And I've tried the component SWF WITH and WITHOUT the fl.video package (import fl.video.*. No difference. Why does the skin load and play locally but not live? It's all AS3. No AS2. And it does not seem to be a "publish settings" issue as far as I can see. The relevant code in my API is:
var AnimalFLVLoader:Loader = new Loader();
AnimalFLVLoader.contentLoaderInfo.addEventListener (MouseEvent.MOUSE_DOWN,fAnimaliaVOn);
Animalia2.addEventListener(MouseEvent.MOUSE_DOWN, fAnimaliaVOn);

I am a fairly new as3 user and am working on a video player that loads an xml file into a URLloader as a playlist. I have everything working but I want to add a few buttons to change the content of the playlist. All of the data will come from the same xml document, so I don't think i have to reload the xml. I can get the content to load when the button is pushed, but it jsut adds to the previous content instead of replacing i. How to clear the content before adding?
Here is my code (that relates to this) so far....
public class playlist_controller extends MovieClip {
private var xml_loader:URLLoader;
public function playlist_controller():void {
////load the xml file
xml_loader = new URLLoader();

I'm trying to read the width and height of a locally loaded image. This seems to work for images that do not exceed the dimensions limited by the Flash Player 10 [URL], but as soon as the images are bigger, the width and height remain 0. The strange thing is that now and then, I can read the dimension of these bigger images, but most of the times not. I understand that this might be because of the player limitation, but then I would at least expect the error to be consistent.
I want to check this since there is no use in loading such a big image as it will not be displayed anyway, but it would be good to provide a detailed error message to the user.
Here's the code that I use to load the image locally and read the dimension:
private function chooseImageButton_clickHandler(event:Event):void {
var allowedTypes:String = "*.jpg;*.png";
m_uploadFileReference = new FileReference();
m_uploadFileReference.addEventListener(Event.SELECT,

So I am relatively new to Flash and After Affects but I managed to make a nice video with Adobe After Effects that my friend wanted to put on his site. After I was done rendering it I used Adobe Media Encoder to make the .avi file into a .f4v file for flash. After opening that flash file with Flash i exported it out into a .swf file. When I opened the .swf it played perfectly, just the way it should. I edited my index.html with Dreamweaver and the coding and everything seemed fine. After previewing the index.html with my browser and Dreamweaver's Live View I was quite satisfied with my results. When I uploaded the files onto my site the flash did not play. It plays locally on my PC but not on the site. I later asked a few more experienced buddies what was wrong and they confirmed that they weren't able to play the file locally nor from the site. At first I thought I may have mixed up the links but they were fine. Here is the code I used for my index.html page.

I'm writing a flex 4.5 application that's supposed to capture a video from a webcam and audio from microphone and save it in some video format (i don't care which format). I use VideoDisplay to display the webcam. how can I fetch and play audio in real time ? Is there a way to save the video locally without using a flash media server?

I have a video interface set up and get the following error....when I play locally,everything plays fine and I don't get any errors, but once I upload to the web, I get the following error:

I am running Windows 7/64 and Master Collection. I've created a clip of DV NTSC footage to test F4V publishing. Done this many times with CS3 and flv files but this has me stumped. I can successfully view the video and web page locally in IE and Netscape but on upload to my server I have the menu and placement right but no video appears. I created the clip in Premiere Pro CS5 and exported to F4V/FLV best quality. Opened an Actionscript Media DV NTSC template in Flash Pro CS5 and imported the video which I had pre-placed in my root web folder locally. I then exported the swf and saved the fla. All files were then in my root folder and the scrpts in the scripts folder. In Live View in Dreamweaver CS5 all looked fine. In each browser locally the video played as expected. Once all files were uploaded the video was not visible.

getting this here Flash website to work. It is an .swf that has four different buttons in it. Each different button uploads a different video thumbnail with a play-button over it. When you click on that thumbnail with the play-button over it, it goes to the thumbnailed video which automatically plays. Here is the link:
[URL]
There are no bells and whistles with the html, it's just tagged and uploaded with the Fullscreen-true so that you can make the video go full-screen.
But see, when I upload the thing, the buttons no longer navigate to the different videos unless the play-button over the thumbnail is already pressed and its video is already playing. I need them to work anyways.

I want a user running a Flash game on his machine (not from a server) to be able to save some game data locally.From what I've read, there still isn't any way to do this, but I thought I'd throw it out there in case anyone knows a sneaky xml or php work around.

I have a huge memory handling headache in a project I am working on. This is basically what the program does. I have a main shell swf that loads a xml document. This xml document points to a interface swf and many content swfs. The interface swf has my container, buttons, and preloader. The content swfs holds images, audio, and other interactions.
My shell loads a content swf and adds it to a container movieclip with in the interface swf. When a new content swf is loaded, it needs to crossfade on to the old swf.Each content swf is set up as such: all of the content is in a movieclip that is exported on frame 1. There is also a large string of text that sits on frame one that is loaded into the interface swf.
1 . I can't figure out how to load / unload the swfs to set them up for garbage collection while still crossfading them when they load.
2 . When I built a test to see if the swfs would unload correctly, It would not unload any bitmap data within the swfs.
My current code is below. This works fine functionality wise but nothing is removed from the memory. I can't figure out how to add an unload script without breaking the crossfade.
Code: Select allvar slide:MovieClip=null;
var isLoading:Boolean=false;
//buildSlide is passed a content swfs url

I made a video player with a playlist. After around 45 min the sound stops! The video continues playing. I play short clips (about 3 to 4 min each). The player is based on 2 frames: Frame 1 defines the variable VidReference with the filename:
[CODE]...
Once the video is done playing it goes to Frame 1 (to put the new value to the VidReference variable) and goes back to frame 2 to play the new video. Am I supposed to delete the video object each time it loads a new video? Am I actually declaring a new video object each time I'm looping (frame 1 > 2) and adding each video to the RAM, and in the end overwhelming the flash player? I've heard about garbage collecting but I wouldn't know how to delete the video object so it is cleared (and the video itself too) from the memory. When I check System.totalMemory it's adding up each time a new video is loaded, I can't figure out how to delete old videos from the memory.

I have an old project in AS2 with a video player that plays mp4s. I've noticed that FF tends to continue to eat up memory even after the video has stopped or has finished loading. I also am noticing jerky playback which I think has something to do with the memory leak.
ActionScript Code:
var server_nc:NetConnection = new NetConnection();
server_nc.connect(null);

I have designed a site with a looping MP3 and video.
Problem is that the memory consumption of the Flash plugin goes up about 40mb every minute, and the site 'crashes' after a while. I would have thought that a single entity, that loops, would not have to re-load into memory, but this is what seems to be happening.
The looping video is approximately 800kb, and the MP3 is approximately 400kb.
how to minimize memory loss/consumption?

I'm making a game for the browser that has a lot of assets, but not all of them are needed at once. I'm deciding whether to embed my assets at compile time or load them at run time. I'm not concerned about loading time -- only the performance of the game during run-time.
If I load these assets and store them into memory for eventual use later in the game, will they consume system resources just being latent in an AssetLoader? Will that affect performance?
If I embed these assets, will they consume system resources just being latent in the compiled SWF?
Is there a difference in performance between these 2 methods?

Is this at all possible? I just finished re-building my entire portfolio site in AS3 because I can't change the frame rate for loaded content in AS2. Now I find out after completely rebuilding this thing that AS2 content gets stuck in Flash Player 9's memory and won't erase on Loader.unload. All my work from years back is in AS2.

I want to use the ActionScript 3 Camera class to capture a video from a local camera (webcam, built-in camera, etc) and then play that video back within the flash application.I'm considering the possibility of sending it to a Flash Media Server and then streaming it back as an on-demand video, but I would ideally like to keep the whole thing client-side for best performance.I'm open to the idea of using a different platform (Java was one consideration) as long as it can be embedded in a web page, but I would like to keep development as straightforward as possible and make the process of accessing the application as easy as possible for the end user, which is why I chose Flash initially.

My problem is going to be hard to outlay in detail due to NDA's I am bound to, but the gist is this..I have a swf application the progressively streams content from a cdn edge server.I have built a video player class and instantiate a new one for each new piece of footage I find.Naturally this requires good memory management to ensure no leaks..... and herein lies the problem (surprise).
I have unregistered all my event listeners (not using weak at present) and nulled all objects from my media player object.I slice it from my list and call a destroy method that cleans up all objects setting references to null. Once this is done I call System.gc().My profiling tools are showing that my memory usage is continuing to increase linearly for each new video clip. The jump is about 5mb each time the approx size of each video file.
Is the built in "Video" component on the stage (players all share the same one) a built in type?

Using ActionScript can I do with my game, which is running in a browser, verify that the user already has the files needed to run the game installed on your computer? If he had these files do not need anything else that was born and can play the game immediately. If he did not have the files, they would be loaded so that the browser does not erase these files. So when he returned to play the same game day after,as the files already on your computer, nothing need be loaded.How do I remove one of the main memory image that was loaded using the Loader class? I tried using the unload () method but nothing happened.

In Flash Actionscript 3, if a function is defined in Frame 1 of a flash animation and the animation loops, does it store another version of the function in memory upon each loop.
[Code]...
If so, is it a best practice to check to see if it's the first time the frame has been run, by setting a variable and checking it's existence, or is it a non-issue because the compiler checks to make sure that a function has not already been defined?

I have an FPS monitor running and notice that I am getting choppiness here and there, bringing my game from 40 to 27 fps and back and forth at certain stages. I have an idea of where it is happening, but do not know for sure. I looked up quite a few memory monitors but haven't found anything decent yet. Is there a memory monitor that allows you to see the memory leaked and find its location? If not, how about just he memory leaked?
