We find a problem about STANDARD FLASHPLAYER PLATFORM,memory leaking on new flashplayer version(10.1.82.72 or newer) happens while testing the flashplayer in live mode connected to the standard FMS in a period of more than 24 hours.the Phenomenon is as follows,the player screen seems suddenly fixed after some time and the memory start to increase ,the peak of virtual memory consumption is up to 1.3 G(2.0G of physical memory),and a moment later,white screen happens with a exclamation point.

i've recently installed Wowza media server 2 locally, currently only for testing purposes.everything works fine, except of accurate seeking functionality - or in other words advancing frame-by-frame .when i use VLC to play my video file i have no problems advancing frame-by-frame. however, when i use the 'seek()' function to move the playhead a fraction of a second, its seems to move only to the next key frame (meaning that only once every few mouse clicks the playhead advances dramatically).
View 1 RepliesIs it possible in flash to get a specific frame in a flv video as a bitmap or an image.?
i saw an example of it online but as the comments said it didnt work and some said that its not possible.
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 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 implementing an Augmented Reality application for android using Flash. In order to get the application working on my Android Phone (nexus One) the Phone Camera must be activated as well. So I need 2 layers one for the background which is the feed of my phone camera and an other one on top of it which is the view from away3d in this case.So setting up a BitmapData object to hold the information of the most recent webcam still-frame I can make this work.
If I use papervision3D library and FLARToolkit we setting up the BitmapData using the following part of the code found from this video tutorial:
//import libraries
import org.libspark.flartoolkit.core.raster.rgb.FLARRgbRaster_BitmapData;
import org.libspark.flartoolkit.detector.FLARSingleMarkerDetector;

I want to call a function once per frame between keyframe 1 and keyframe 60, but i don't want to have to create a keyframe on EVERY single frame in between with an action calling the function. is there a simple way like tweening, to make this function execute once on every frame without having to make 60 unique keyframes?
View 1 RepliesI'm making a photo browser. I load 15 photos as Images and add these Images to HGroup every time. 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?
View 1 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.
I' making a flash file with AS2 in Flash CS3. I put a FlVPlayback in stage and let it load a couple of FLV files from my local HDD and playing continuously. I use "addEventListener" to check the current running flash movie is completed. After complete event occur, I load another flv movie to paly again.Here, I noticed that memory usage is increasing every time a new flv file is loaded and played. I heard "addEventListener" in CS3 is causing the memory leak and not being detected by GC. [code]

We also tried with function LoadVariables but we got the same results (MEMORY LEAK).Is this a bug in a Flash or we are missing something?Is there any other possible way to read variables from php script.

I have a problem with a project using the FLVPlayback component (the Flash CS4 version) and FMS 3.
Playing back a video works fine. When the video is finished, I hide the FLVPlayback component.
But if I have to play the same video again, the video does not immediately start from the beginning. I see a glitch with the frame the user last stopped on (whether it stopped at the end or wherever in the middle). It never re-starts from the beginning right away.
I have tried different approches to solving the issue:
- tried seekSeconds(0) - tried autoRewind = "true"
- a combination of both
- nulling out the stream source (result in a Runtime error) then setting it again
To no avail.

I'm working with a large modular app, and most of the swfs were made in Flash Professional. When I load the app in the Flash Builder Profiler, the memory usage appropriately goes up and down as I add and remove modules. When I flip between two modules many times, I end up with the current memory in the Profiler more or less where I started at around 2 megs. System.totalMemory, however, shows that the flash player has only been allocating memory and is currently using 106 megs. Is there a certain bug known to do this, or is there a better way to detect memory leaks? I'm using the latest flash player debug version.
Note: The SWF modules are all permitting debugging, and the Profiler picks up objects in them.
I'm quite confused on what differences there can be between different versions of the flash player. Since I started coding my last game I've been testing it on chrome and firefox with good results (flash player 10.3.xxx). The memory needed to run it is always around 20 MB and also the cpu usage is pretty low. Also with the player 11 beta on ie the memory needed is around 50 Mb. But when i try to test it on the flash player 10 something is not working, the memory used by the game keeps growing and the garbage collection seems to be in holiday. Can this be related to the fact i'm coding it with the last cs5 (in as2)? Or since it's a board game i needed some listeners that could create this problem?
View 0 RepliesI'm having a rich media banner to deliver.. soon. I've imported it and set it to loop with autorewind parameters.
Now: How can i make it to loop 2 times and stop at the last frame ( seconds 00:12 / frame 370) - where it shows a still shot of the product - ?
I was using a trial edition of flash builder 4 professional and I figured before it ran out I would test the profiler. What shocked me was the number of objects that were left resident in memory. After seeing that I decided to set up a small test and had very bad luck. I was hoping someone can look at the following and tell me assumption i have that is just wrong.

I am currently working on a music site that has a custom built mp3 player, where the action script calls to an external xml. It works beautifully. It is all on one frame.... in the background of the music player is edited video that I manipulate in final cut. I have next and pre buttons that call the xml. What I am trying to do is change the video when the song is changed. Im not sure if I call a fuction to the button next frame + or - 1 or if I can call the video to the xml. I am a graphic designer learning code and am not sure how to tackle this. This site is my senior project.

I want to draw some combination of bitmaps, flash shapes, vectors, text etc and draw them programmatically into my movie using ActionScript, and then get every "rendered" pixel of my movie (at 100% view) into an array that I send to another program over TCP/IP. The first part of the question is if its possible to render a frame that is a collection of Flash elements as a bitmap? I know that I can iterate through a bitmap and get every pixel using the getPixel method but I'm trying to access the final rendered frame displayed on my screen, including, as I said Flash shapes and text.
The second question is what would be the best way to send this "video frame" over TCP/IP? Would I use an XML socket connection? That is the only way I know how to send data out of Flash over TCP/IP but I don't know if it is the only way - the help page says the data needs to be formatted as XML, which seems unwieldly for this application. I'm doing this now by using Max/MSP/Jitter to do a screen capture the size and location of my Flash movie and then send out the resulting matrix using a "jit.net.send" object (which lets you send frames of video over TCP/IP), but this is too clumsy for the installation I am building.
I'm very new to flash,and have been digging through google and this site for information on how to piece together an AS2 shooter game.Its going well enough, but I'm having slowdown issues the longer the games runs, and I was hoping someone here could point me in the right direction.To paste an enemy movie clip on the screen, i'm using this:
Code:
var spawn =_root.attachMovie("monster1","monster1"+_root.getNextHighestDepth(),_root.getNextHighestDepth())[code]........
I need them stored in an array so that the player's shots can test weather or not they've hit any monster on the bullet's enter frame function, then call that monster's movie clip's take damage function. I'm using a for loop to do this:
Code:
for(var i in _root.player.foes){
if (this.hitTest(_root.player.foes[i])){
_root.player.foes[i].takedamage();}
}
I think the problem with the slowdown is that each time I place an enemy on the screen the array gets bigger and bigger. The slowdown only happens while the player is shooting, and I suspect the ever longer for loop with the hit testing is causing it.
I'm already removing the monster's movie clips as they get killed or exit the screen, I guess what I need is a way to reduce the size of the array at the same time, or at least tell the for loop not to do a hit test unless the monster is still alive.
I am making a custom renderer using the copyPixels function for my Haxe/Flash game. So I have this kind of code :
buffer.bitmapData.copyPixels(m_CurrentSkin, RECT3, POINT, null, null,true);
where :
-buffer is the bitmap where all my scene's objects are drawn
-m_CurrentSkinis the BitmapData that contains the current frame of the object to be drawn
Every time m_CurrentSkin contains a BitmapData that have never been drawn (the first time that an animation frame is drawn for example),I have a memory leak that is not garbage. However if m_CurrentSkin contains a BitmapData that have already been drawn (when the animation is played a second time for example), there isn't any memory leak.If I comment this line there is no leak so the problem comes from there.It seems that a copy of the BitmapData is cached in memory but I have checked in my code and there is no cacheAsBitmap explicitely set to true.
I am trying to find out how to stop the memory leaks that I seem to get when making up dynamically loading picture slideshows. It is difficult to try and give a perfect example of this so I would rater try and show it in action. Here are 2 separate tutorials on how to build a slideshow, though they are slightly different I think this will illustrate my point, there is one problem and that is that the only browser I know of that will show this correctly is Safari,[code]....
Ok now in safari open up your Activity window and take a look at how these 2 different slideshows seem to operate, Link 1 seems to have a memory leak,because each time the picture loads a new instance of it, if this were automated it would be a far bigger issue, like the second url of Link 1.Now when I make my own slideshows I find that mine are also like the first and second links and not like the third.
i am working on this project wherein i instantiate an flvplayback at stage and let it play ,, after playing i instantiate 1-4 flvplaybacks on stage and the user kan nove choose a new film to watch .. but each time i instantiate the flvplayback(s) the project gets slower and slower .. the video gets bugggy and the sound is out of sync ..if anyone can see something wrong with the way i do it i would be ever so happy

While tracking down the source of a memory leak, I stumbled upon a strange issue with AS 3.0 and loading external flash movies. From what I can tell this somehow related to the custom classes stored inside the loaded movie. I have two versions of a basic file that contains one image on the stage (I also tried this with vector graphics with the same effect). One version has a custom document class (just a simple extends MovieClip with no additional code) and the other has no document class.
The graph below depicts the memory usage from loading the file without a document class.It performs the garbage collection as you would expect after each unload operation.However when I try to load and unload the same file with a document class, I get the following memory usage graph. As you can see, memory usage is slowly creeping up with each load operation.It almost seems that Flash is caching the class files, so I tried changing the application domain for the loaded content without success. Even if Flash was caching the class files I would assume that it would be able to detect that it had already cached the document class and simply re-load the cached version
