CPU usage when scaling the flash player

Do anybody know about how flash player render the content when we do the scaling?
Let's say i have 2 flash swf file.
swf1 : the stage size is 2000 px x 2000 px. + 1 movieclip with 100% transform
swf2 : the stage size is 1000 px x 1000 px. + 1 movieclip with 50% transform
Let's say there is a movie clip on swf1. So i copy the same movie clip to 1000 px x 1000 px file and transform the movieclip to 50%.
So it will look the same if i scale the swf2 x 2.
If there is any different on swf1 and swf2 in team of CPU usage or etc?
Like is it true when playing swf2 need more CPU usage than swf1 because swf2 need to do the scaling but swf1 not.
Just not sure which way i should develop the content.
Because i have to make some content and the width/height are about 3000 px. So i am thinking if i should set the stage close to limit 2880 or just make the content like swf2.
And my concern is if it will use more CPU when do the scaling.

Thx Justin.
Yes, it is for video wall. And it may more than 5000 px.
But I don't really scale it in the flash file and i didn't handle anything about the scaling. It scale when doing full size of the screen. So if my content is 1000px and put it to 5000 px resolution. It will scale to 5 times more in the flash player.
So is it any different if i make the same content on 2000px stage and 1000px stage? The stage for me is just a reference size for the flash player. And the flash player will handle content depend on how many pixel show on the screen. So if i import a 200 px bitmap and scale it 50% on 1000 px stage and import  a 200 px bitmap and scale it 100% on 2000 px stage, the 1000px stage will look half size of 2000 px. But when i scale the flash player to double on 1000 px stage swf, the picture quality and anything will look the same as 2000 px stage swf.
So any different between in team of the cpu, ram or etc?

  • ITunes 10.6 has High CPU Usage when switched to Mini Player

    iTunes has high CPU usage when switched to mini player. The CPU usage goes to 80-100% when the next song is played in Mini Player. iTunes then stays at high CPU usage.
    Upon exiting mini player the CPU usage will drop back to the normal 0-5% levels.
    This only happens when playing from the main music library; which my library is at 7089 items, 42.04 GB.
    When playing from a smaller playlist such as a smart playlist with about 15 songs in it for example, the CPU usage stays low/normal.

    Do you have any better luck with that if you update to iTunes 10.6.1.7?
    From the notes for the release:
    iTunes 10.6.1 provides a number of improvements, including:
    • Fixes several issues that may cause iTunes to unexpectedly quit while playing videos, changing artwork size in Grid view and syncing photos to devices.
    • Addresses an issue where some iTunes interface elements are incorrectly described by VoiceOver and WindowEyes.
    • Fixes a problem where iTunes may become unresponsive while syncing iPod nano or iPod shuffle.
    • Resolves an ordering problem while browsing TV episodes in your iTunes library on Apple TV.

  • I can't see the video when using the flash player

    Hello everyone, I am having difficulty trying to fix the video of my adobe flash player.  The audio works well on the flash player but the screen is black for the video.  I have read the helpful tips on the adobe website and I have already: downloaded the most recent flash player, managed the add-ons, unchecked activeX filtering, deleted the flash player browsing data, and removed the flash player cache.  I am at a loss for what to do next.  Youtube works fine, but when I go to cbs.com to watch full episodes I can't see anything.  It would be greatly appreciated if anyone can help.  Thank you, Aaron Weinstein

    I went and look up that information and then I went to the AMD website do download the graphic drivers and software and it said that it couldn't so I should contact HP.  I then went to the HP website, put in the information of my computer and looked to see what graphic drivers I could update.  Unfortunately I have the same graphic driver that they are saying is the only update for my computer.  I appreciate the suggestion but it didn't work.  Thanks, Aaron

  • When will the Flash Player be available for HTC phones?

    whaen does the flash player become available for htc phones, send me a message please...

    I wish I had some way to give you hope but unfortunately you're definitely not the first person to ask this question.  VZW has made it clear that they aren't in the customer service business so we now must take matter into our own hands.  Write directly to the CEO.
    You can contact Mr. Daniel S. Mead (CEO) by going to www.verizon.com/about/leader/contact/73.

  • How do you stop the flash player when you change pages on a web site

    Hi all;
    I'm building a website in flash using my limited understanding of action script.  Everything was progressing very well until I found that if I go to one of my example pages of my web site and play the flash video (with audio) and click back to my "home" button, the audio will continue to play.  If I go back to the example page, the video is off and when I start the video, it plays again with the other audio.  I hear the audio twice! I know there is an action script to handle this but, I can't figure it out.
    My question is, How do I stop the audio when I click away from the example page back to the home page or any other page?
    Thanks in advance for your help.
    I'm usinf Flash CS4 and a Mac OS operating system.

    The problem is most likely in your Action Script. Therefore this question should be posted in the Action Script forum. This forum only deals with the Flash Player, which, in this case is running the script as it is written, and therefore, working properly.

  • Can the Flash Player do frame accurate seeking when using the HDS protocol?

    Hi all,
    ... and thanks in advance for taking the time to respond. I've been playing with different media serving protocols, and I have a couple of questions.
    1. Can the Flash Player do frame accurate seeking when media is served via the HDS protocol? (I know it works  using RTMP)
    2. If it does work, is it impacted in any way if I also use Access DRM-Core or Access DRM-Professional? (I want stronger DRM protection than simple Access Protected Streaming)
    Thanks!

    Hello Simona_83.  Try downloading Google Chrome (it's free).  Install Flash Player via Chrome, and use Chrome as your browser.  This is the only thing that worked for me after over a month of trying everything under the sun to get Flash Player working again.  You'll have to use Chrome as your browser in order to have Flash Player capability, but so what.  It works.  If it works for you as it works for me, you will have Youtube again; you just have to access Youtube via Chrome.  Don't waste hours of your life trying to get Flash Player to work any other way.  Believe me, I wasted hours upon hours off and on over the course of a month trying to get Flash Player installed and operating.

  • When I install Flash Player version 10.2.152.32 it shows up in the control panel but only ....

    When I install Flash Player version 10.2.152.32, it shows up in the control panel, under Programs and Features but the only thing that shows up is the name and version of the product.  On the right hand side, the size of the program in megabites is supposed to be displayed but it isn't for flash player.  I am using Windows Vista Home Premium and it is a 32 bit operating system and the browser I use is Windows Internet Explorer.  Does anyone know why I could be having problems downloading this?

    What is the problem you are having?  Does Flash Player work?  Can you see the Flash animation at http://www.adobe.com/software/flash/about/ ?
    Flash Player is a browser add-on, not a standalone program, and most likely therefore does not indicate any program size in the Control Panel.

  • High cpu usage when the system is idle

    I do have a high cpu usage problem when the system is idle. I bought the laptop (lenovo x230 tablet) with windows 7 installed in it. Then upgraded to windows 8. But ever since I have problems with high cpu usage by the system even when the computer is idle.
    Only the system by itself uses around 30% of the cpu all the time. I ran xperf, and here is the result of it:

    Thanks,

    Hi,
    I'm sorry for that the log you provide can't be opened on my computer. While according to your description, it should had a special process that consume CPU usage when system idle Iguess, isn't it?
    You can use
    Process Explorer to monitor the process activity, may be we can find the reason of this problem.
    Note: We can use Process Explorer to check the Stack of every process then analyize the problem in deep.
    To gave a better insight about this problem, you can take a ScreenShot for this problem and provide the picture here.

  • When I try to run video on any website, why do I get just the Flash Player logo?

    And why is it so difficult to get an answer to this basic question? The problem started on this computer just a week ago; until then, YouTube and any other video-oriented website ran fine. Now every video I try to view comes up as a blank (gray) screen with the Flash Player logo Anin the middle of it. I've jumped through every hoop on the "Help" website, to no avail.

    Hi Rosa,
    Please try the offline installer posted at the bottom of the Installation problems | Flash Player | Windows page, in the 'Still having problems' section.  There will be three (3) installers.  Since you're on Windows 8.x, ignore the installer for ActiveX Control, as Microsoft embeds Flash Player in Internet Explorer on Windows 8.x systems.  You'll want to download the 'Flash Player for Firefox - NPAPI' installer file.  If you also use Opera browser you'll want to download the 'Flash Player for Opera - PPAPI' installer file.

    Are you running Lion v10.7 by chance even though your profile indicates v10.6.8   ??
    I ask because you can only reinstall apps using Lion Recovery
    Much better to ask for help with Safari here before trying to delete the app and reinstall.
    Is the Safari app still in the Trash by chance?
