I am loading an XML file (fairly large document). It takes a high amount of my CPU(almost 100%). This prevents me from working on other applications. Also, it takes a lot of time to load.
reduce the CPU usage.
I have an AIR application, I use SwfLoader to load another swf file to display in this app. The problem is the CPU Usage always takes over 50%, but it only takes 15% when the swf file runs in standalone mode.
View 1 RepliesAs more and more FLV videos are moving to HD, I'm noticing high CPU usage and lots of dropped frames when playing FLV video in web browser with Flash 10. This is true even if the video isn't full screen. I've tried a variety of browsers (Firefox, I.E., Chrome) and the problem occurs on all of them so it's pretty clear it's a limitation in Flash.
Now my PC isn't high end (it has a Pentium M 1.86 GHz processor), but I can take those same FLV files and load them in something like Media Player Classic or Windows Media Player (when using ffdshow) and play the FLV files full screen with little or no drop in frames and an acceptable CPU rate.
This is especially annoying on sites like YouTube where I actually have to save the video and play it back in something other than Flash to have it play back at an acceptable rate. This doesn't work for other sites like Amazon.
Why is the CPU usage so high when decoding and displaying videos when compared to other media players?
I have helped write a program in AS3 that uses classes. We have 2 frames in our movieclip that consists of an ant moving. We have a class of ants and can create 15 instances of them and the program runs fine with the ants walking around looking for food and going back to a corner that is their nest and going back out again. The ants also respond to mouse movement if the mouse pointer is near an ant.
If we create more than 15 ants, then the program starts to slow down. If we have 30 ants on the screen, then there is noticable stuttering of the ant movement. The CPU usage on a P4 2.5Ghz Pentium is around 50%.
I've hired a freelancer, to make a design for my flash app. And everything was fine, untill I saw this. It was an animated background. It has about 100 tweened movie clips, that do pretty much the same - simple rotation tween, but cpu usage on that background only reaches 17-20%. Its high for such a small effect. I've tried to optimize it - removing all code, and leving just timeline based tween, but that didn't solve my issue.[URL]
View 2 RepliesI'm building a GUI for a karaoke system which uses Flash IDE.
Im not doing the OOP method, if you ask me why, its becoz I code slower with OOP and I need this urgently.
Anyway, I had only created 3 scenes with several simple MovieClips in it and some png files as button icons.
When I try to publish it and run, i noticed it will just freeze my Flash IDE and I've checked the CPU Usage in TaskMgr, it shows over 50% usage.
The filesize for this FLA is just 992KB, so you can probably tell that it doesnt have much bitmap in it.
I am hoping someone in this forum could show me some light as I've already struggle for the past 12 hours with no luck at all.
I'm working on a new site and one of the things the client likes most is the idea of these gears that are constantly rotating on the screen. However, now that I have the mock-up design done, I'm noticing that the constant rotation requires a lot of CPU to maintain. Has anyone else experienced this and have you figured out a better method than the one I am using to rotate the movieclips?

I've been deploying video to the web via Flash for a couple years now and I was curious if anyone has experience with / knows if deploying video via a Flash Media Server or any other type of video centric server has a significant impact on performance playback? I've noticed lately that with YouTube content, often available in "HQ" or "HD" that the video playback suffers very marginally when switching to higher quality video. However, with video players I have developed, using HTTP progressive download, CPU usage often spikes during download of the video and decreases once it's been cached. I've also recently employed pseudo-streaming techniques with the help of XMOOV but this doesn't seem to have much of an effect on CPU usage during video download.
My video player was developed in AS3 and while it's not using a class based structure, it does follow general OOP techniques. Would a class based video player improve performance? Here is a link to a work in progress video player: [URL] Please try a couple videos and let me know if they play back smoothly and / or if you notice CPU spikes. Also note that the only video that makes use of XMOOV is the "Make a Wish" video as it's been injected with the necessary metadata.
my flash has lots of images and dispaly objects. Hence it costs high cpu usages. after using my flash for an hour, it is dieing.I am trying to reduce it. I have some questions here:
1. I create an array, or string at frame 1 for example, when I go back to frame 1, should I create a new array, or a new string?? Or is it better to make it empty array(eg:[]) or empty string("")? which way it reduces cup uasge more?
2. does anyone know how to force the flash to do garbage collection??
3. any other possible reasons that cause high cpu usage?
All three of my family's computers have been experiencing problems with the firefox plugin container. The container spikes the CPU for long, long, periods of time slowing overall performance noticably.The only way to address the problem is to kill the Firefox plugin container.When I kill the plugin container it kills Adobe Flash.I've tried clearing the flash cache from the Adobe troubleshooting site, deleting all cache applications, and changing settings.My family plays Farmville which is always hanging and can only be fixed by restarting the computer. Okay, maybe farmville is a bad app.

I've created a Flex website that plays a video using the Spark VideoDisplay component. When selected, the VideoDisplay loads in the PopUpManager.
This works fine in all the browsers, except Google Chrome take significantly longer to start playing, during which the CPU usage peaks, then goes back down once video starts playing.
I've traced the player states it goes through and they are as follows:
Loading ready (hangs for ages with high cpu) buffering playing (immediately after buffering, CPU usage goes down, video plays smoothly)
What could be causing this to temporarily hang for so much longer in Chrome? I thought I could expect the same functionality and behaviour throughout all the browsers, as Flash is simply a plugin that runs as a separate process?
Edit: It seems that it's the same in Opera too. Is there any commonality between the two that would explain this behaviour?

how can i make a high score table for a flash game where EVERYONE see's the same high scores?

I've tried loadMovie("exampledomain/sampleimagefilename", obj.mc); where "obj" is an object of a class who has a MovieClip variable "mc", and then using _root.attachMovie(obj.mc,"testInstanceName", _root.getNextHighestDepth()); to add it to the stage.That didn't produce any visual results whatsoever. To ensure the URL was being loaded properly, I changed loadMovie to _root.loadMovie, in which case the image was loaded (but, of course, replaced my entire Flash movie).
View 6 RepliesI 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?

View 2 RepliesI just upgraded to Flash CS4 on my laptop. program that used to take 5 seconds now takes up to 2 minutes. I installed the 10.0.2 update, and searched the web for a solution. I am desperate because all of my programming is based on CS4. I know how to compile a swc and use FlashDevelop with the compiled graphics, but this isn't a solution for me. Whenever I need to make changes to the graphics I can't wait this long. I am using an HP dv5-1190. This meets the minimum requirements by far.

I'm having a brutal time with a FLA. The wait time to open this thing is ridiculous, and alot of the time the program will just become nonresponsive. Its only this one specific file, as others open fine. It also has nothing to do with the hardware on my system, as we've tried the file on a variety of machines.The FLA itself contains very little bitmap art, most is vector. It's about 16mbs, but publishes down to a SWF thats about 300kb. There were some complex vector elements which were removed in a fruitless attempt to get this thing to move faster. Trying to "save as.." results in flash writing to a file extremely slowly. The resulting file will progress in size from 2 - 4 mb with about 10 minutes wait time in between. Its becoming nearly impossible for us to work in the file. how I could debug Flash itself to find out whats going wrong on load/save?
View 3 RepliesI have a problem when saving flash files in a mac. The process is much slower than in my other computer with windows, using the same file. I save my flash files very often and having to wait that long is very annoying. The problem can't be the file itself, I have tried saving different files and there is always more delay in mac compared to windows. In my mac I have OS X 10.7.2 (Lion) with Flash 5.5 and in my other pc, Windows XP SP3 with Flash CS 5. Has somebody experienced this before? What could be the origin? It's weird because my mac is new and is supposed to have better features than my windows pc which I bought many years ago I am a relatively new mac user and I have heard some people complaining about Lion OS X. What is your opinion?

I've found two very strange pieces of code in PureMVC's documentation:
[Code]....
(found in Best Practices [English], bottom of page 38 and top of page 39) I've always thought that getters must not accept a parameter (and FDT indeed tells me that "Parameters for getters are not allowed"), so I wonder what's going on here. Is that just an unfortunate typo (meant to be simply a normal function without the "get") or some hidden feature/voodoo?
I have a flash file that consists of a number of loops that play in series that allows me to change the duration of each part of the movie dependent on what is in the loop. Therefore loop 1 plays x number of times before moving on the loop 2 that plays y number of times and so on. I had worked out all my timings so that each loop last half a second. The number of times each loop plays is controlled by an if statement on the last frame of each loop. So far so good. In this main movie have another movie clip that runs independently of these loops and I noticed that although it was the same length as the main movie taking the loops into account, it would drift out of sync as the main movie progressed and looked as if it was running slow. However by tracing frame numbers of the two movies, I noticed that each time the main movie reaches on of the if statement frames although it appears to increment by one frame the other movie doesn't. By commenting out all the if statement frames both movie run in sync.
Therefore I conclude that a frame that controls the playhead position in this method does not actually last a full frame in duration, but jumps immediately to the new frame as soon as the command is encountered. Can I assume that this is constant and that frames used to move the playhead occupy no time in terms of the main timeline? Is there any documentation on this?
