I wrote the following code to check memory when loading a big image (~20Mb). Every time I do mouse click, the application eats up memory, so something doesn't get deleted or cleaned with GC but I can't figure out what exactly.
imageLoader.as
PHP Code:
package {
import flash.display.Loader;
import flash.net.URLRequest;
public class imageLoader {
var fname:String
[Code] .....
I'm trying to get smoother steps in checking the ProgressEvent when loading the image to the Loader.At this moment my eventrogressEvent checks the progress aprox twice within a second. Is there any way to make it check constantly (or more often), so the progres bar "grows" smoothly instead of "jumping"?

View 7 RepliesIs there a way to check whether a loader object is in the process of loading something? I need to create an if statement that checks if the loader has an open connection. So far, what I thought of is:
ActionScript Code:
if(loaderInstanceName.contentLoaderInfo.bytesLoaded > 0)
{
// do something
}
Here, I'm just assuming that if bytesLoaded is greater than 0, than it's probably loading something. But I don't think it will revert back to 0 after the loader finishes loading an external resource. So after that, bytesLoaded will always be greater than 0 even though it isn't in the process of loading anything. Is there any other property that I can use which says whether the loader object has an open connection?
in AS3 to check if a file exists before loading it. There was not very much about so I wrote these classes to do it. There are two classes, the FileLoaderUtils and the UtilEvent. the FileLoaderUtils has the function doesFileExist(url:String) and when called the class uses the URLStream class to attempt to load the file. If the file exists a UtilEvent.FILE_EXISTS event is dispatched. If the URL is incorrect or the file doesn not exist a UtilEvent.FILE_NOT_FOUND event is dispatched.
View 7 RepliesI have a loader SWF that runs some code in the background and loads other SWFs. Using this code:
private function loadScreensaver():void {
screensaverSWF = new Loader();
var req:URLRequest;
switch(areaNumber){
[code]....
I load the screensaver and add it to the stage. Using MonsterDebugger I can see that memory steadily rises from around 80mb upwards until the application exits (Im using windows projector). What I can't work out is why, there is no code attached to the screensaver SWF, just some timeline animations of things fading in and out.
EDIT:I've kept testing and found where I have an image that starts of stage then tweens on and off and is removed. When it loops it adds to memory again, as if the first image is still kept. This is all done on the timeline.
In flex, what we do, we normally upload the image from flex end and upload it to the serveri want to know, can we do some details checking, like i want to find out the imageesolution(on the client side) before it is uploaded to the server,There are going to be two profits, first the client doesn't need to wait for long to image get uploaded, and in case if finding the image resolution is on the server end, so it willtake time, even the image to be uploaded is not of expected resolutionsecond, the user interaction & interface with the flex application will be improved,

When user presses 'next page', I first unload the existing Images by 'Image.unloadAndStop()' and 'Image.source=null', and then load new photos. However, it seems that the GC never works. The task monitor shows that the memory use of my AIR reaches as much as 1.2G! Some people said it's a bug of Image when you load a picture larger than 1.5M. Is it true?

I have an interface that needs to load in external activity pages - there's quite a few of these. I've been trying to create an external class to take care of movie loads, but it has a bad memory leak. I've been reading about using unload() and unloadAndStop() but haven't gotten these to work (there are no noticeable differences in system memory usage or performance). Everything grinds to a halt once I've used up about 13+ Mb of memory.
The document class has lots of code (of course) so I'm just showing the code that relates here:
Code:
package {
public class Interface extends MovieClip {
static public var _ui:MovieClip;

I have a problem in that i have a holder swf which loads in other swf's externally. My problem is that the holder loads all the movies in correctly but the memory usage of the swf just keeps going up and up even though i am trying to remove the movieclip after each has finished it's run.
[Code]..
I have a flash application running on some local machines. There are 3 movies the flash loads and plays. Each time a movie is played, it makes the amount of RAM the swf is using increase. This is being ran in a museum and users step through the 3 movies over and over and over, causing the swf to use gigabytes of RAM and eventually locking up the flash player.
Here's where I create the movie playback component.
ActionScript Code:
var flvPlayer:FLVPlayback = new FLVPlayback();
addChild(flvPlayer);
The 3 movies are on 3 different frames in the timeline, for each frame I have this code that loads each movie.
ActionScript Code:
flvPlayer.source = "resources/LADEE_overview.f4v";
flvPlayer.play();
flvPlayer.addEventListener(MetadataEvent.CUE_POINT, cuepointfound);
I use the cuepoints to display some text on screen. I also call a function that does flvPlayer.stop(); each time the user navigates away from a movie frame. So is the RAM usage growing because of the flvPlayer.source = "whatever" being triggered each time the movie is called up?
I load image from url like this
Code:
imageholder = this.attachMovie("imageholder", "image", this.getNextHighestDepth());
imageholder.swapDepths(selectMenu);
loader.loadClip(uri, imageholder.bigImage_mc);
this== root, imageholder is MC that contains empty MC named bigImage_mc, selectMenu needs to be in front of loaded image (2nd line) and loader is MovieClipLoader()
Image is unloaded and removed like this
Code:
loader.unloadClip(imageholder.bigImage_mc);
imageholder.swapDepths(selectMenu);
removeMovieClip(imageholder);
but when I unload image it doesn't free any memory, and when i load new image it increase memory usage...
I even tried
Code:
System.gc();
System.gc();
after removeMovieClip(); as I found this on some website... but with no improvement
I have a flv player that seems to only work in IE and not FF?? The player works fine in the flash authoring environment. Since it does work in a browser, that eliminates its being a sandbox problem.
Does anyone know if flash loading js classes into the container browser memory?
My Problem: I simply want to load a swf in a swf and then unload it. When I do this it works and cleans out "some" memory but after I unload the swf the memory usage grows a little each time. Shouldn't I be able to have this so the memory hits a limit and doesn't keep growing forever?
What I tried: I put in System.gc() for debugging to force garbage clean up, and I am testing it in the debugger in the browser.There are 2 static images in the swf that is loaded and unloaded. I feel like those images are staying in memory maybe? I am assuming that the "unloadAndStop()" should handle that though.I put an enterframe listener which I remove along with the unload button.
My Code: The code is below, my files are larger than the upload limit here, but you can download all the files from this link: http:[url]....
Main swf to load into:
Code:
var _swfLoader:Loader;
var _swfContent:MovieClip;[code]............
[URL]
The movie loads in an external image and refreshes it every second. What happens, though, is the previous image seems to stay in memory. Eventually the browser will hang, because the memory footprint of the flash movie is so large. Even while testing outside the browser, I can see the memory increase by a couple hundred KB every second. You can see it at [URL]
The code I'm using is below (don't make fun, I don't claim to be a programmer).
Code:
function refresh_url(event:TimerEvent){
var url:String = "http://www.live-photo.com/asheville-east.jpg?ID="+getTimer();
var request:URLRequest = new URLRequest(url);

Im creating a flash projector which has a holder swf with an empty movieclip. A series of external SWFs are loaded into the empty movieclip on the push of a button. Once the clip has been loaded, other external SWFs can be replaced in the empty movieclip at the push of a button. As memory leaks and garbage collection seem to be an issue, I was wondering the most memory efficient way of loading, unloading and replacing these external swfs so that memory leaks are kept to an absolute minimum.

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 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?

View 2 RepliesIs there a way to extract a single file from a zip file in Adobe AIR?
I'm using NoChumps zip library to extract files from a zip. In this library the entire IDataStream is loaded into memory and after that you can extract file entries easily. In cases where the zip is 5 to 10MB there are no problems. But when the zip is 80MB, which many are, 80MB is loaded into memory. This causes the app to crash and run slow on mobile devices. According to the zip specification,
"A ZIP file is identified by the presence of a central directory located at the end of the file, this allows appending of new files. The directory stores a list of the names of the entries (files or directories) stored in the ZIP file, along with other metadata about the entry, and an offset into the ZIP file, pointing to the actual entry data."
Also, I do not have control of the size of zip files but most average is 60 to 100MB. Files inside are ~4MB.
