High Cpu usage flash 11 while videobroadcasting

Good day,
in flash 10 my avg cpu load was 50-60% while broadcasting 7-8 websites at the same time
in betatesting flash11 this has gone a little bit up but was still within margins
when the definitive version came out, i am only able to broadcast 3 sites with a CPU load of 90%
please tell me what i can do to lower cpu usage.

The linux version of flash has no hardware acceleration for most (it has mediocre acceleration if you have an nvidia card that supports vdpau), so it uses lots of cpu. On my laptop with a core i5 2.53 ghz, a 720 flash vid will use 20-30% cpu. The same video played in a native application like mplayer will use like 5% (and I don't even have any video acceleration enabled in mplayer because vaapi is buggy for me)

I recall reading somewhere that the mms.cfg tweak to force hw accel no longer works in flash 11, but I cant seem to find the source on that now.

High cpu usage after a while

Sometimes, after a while, firefox (36.0.4) uses up 1 core of my CPU (is a quad core due to hypertreading). The way it happens is really strange. Many tabs without a problem until suddenly ff decides to floor it. This is alway in the run, not on startup or close. All add-ons need to ask my permissions to be activated, this includes flash.
On close, I ordered ff to clear all history and cookies.
Notes that could be important (The behavior encountered while using it. This varies from time to time):
opening new tabs (a lot or a few) => "heavy" load during site loading, then idling
==> The above makes sense
- same as above but load continues to be heavy. => could be some badly written javascript on the site, however, sometimes this occurs with sites I know have no stressful javascript
==> The above seems odd
- Browser is idle in the background (not actively using it). Then all of the sudden "lets floor it until closed".
==> The above seems pretty odd
- When confronted with high CPU usage, closing ff doesn't close it (the ff process remains active. Not a ff process, THE ff process). => High CPU usage remains
==> The above looks like that there is definitely something wrong here
This last one has some other things to keep in mind
- When it happens and I close ff, upon restarting it it will ALWAYS ask to close ff. After confirming to close it, it will start and behave normally.
- When killing ff via the task-manager, or other means like powershell commands, restarting it will result in an idle ff even after every tab is loaded again.
I hope this isn't a heisenbug and there is a solution to this, a reboot ff button would be a nice workaround though. I personally think that it must be some routine in the code that decides to go nuts for no reason.
If you need further details, feel free to ask.
Thanks in advance

Tried those before and tried them again. Unfortunately, the problem keeps repeating itself at random times. As said, sometimes it doesn't occur and sometimes suddenly it does. Keep the following things in mind about this, what seems like a heisenbug, behavior.
- opening new tabs (a lot or a few) => "heavy" load during site loading, then idling
==> The above makes sense
- same as above but load continues to be heavy. => could be some badly written javascript on the site, however, sometimes this occurs with sites I know have no stressful javascript

==> The above looks like that there is definitely something wrong here
As stated, a reboot ff button would be a nice workaround. I personally think that something like a tread must get stuck in some sort of infinite loop. Browsing in ff works just fine though. I just don't like the fact that I turns into a "gasoline guzzler".
Again, thanks in advance

While we're aware of the issue, there's not much we can do about it. The modern security realities facing web browsers have made sandboxing a necessity.
There's a good explanation of what's happening here: http://blogs.adobe.com/asset/2012/06/inside-flash-player-protected-mode-for-firefox.html
Long story short, each video packet has to be passed from the browser to a medium-integrity broker process, then to the low-integrity flash player process for rendering. If an attacker manages to hijack the Flash Player thread, the process is low-integrity, which prevents the attacker from doing much with it. While it's not an absolute guarantee (nothing in security is), it raises the bar significantly for attackers.
The downside is that all of that extra message-passing consumes CPU cycles, especially if you're trying to fill an exceptionally large buffer as fast as possible. There's not a lot of opportunity to optimize this.
If you're fine with the risk, you can manually disable ProtectedMode on your machine. If you're only dealing with trusted sites, and you're not doing anything critical with the machine (work, banking, etc), then it's probably not a huge deal.
Ultimately, ProtectedMode is like a vaccine -- it's a herd-immunity thing. If the majority of people run it, exploits targeting machines without it are inconsistent and probably not worth pursuing when you look at the effort involved in developing an end-to-end exploit. If a large number of people disable it, it becomes economically attractive for people building botnets, and you'll have a problem if you're not using it.
To disable Protected Mode, add the following line to your mms.cfg file located in:
Windows 32bit: C:\windows\system32\macromed\flash
Windows 64bit: C:\windows\syswow64\macromed\flash
ProtectedMode=0
If the mms.cfg file does not exist, create one using any standard text editor (e.g.. notepad)
Depending on your operating system, you might need to first save the mms.cfg file to a writable location (such as your documents or desktop folder) and then copy the file into the destination folder using Windows Explorer.
To re-enable Protected Mode, simply remove the line from the mms.cfg file.

High cpu usage when using flash player

Hi,
Just updated to Mavericks and now I'm having very high cpu usage while watching streams using flash player. CPU usage is somewhere around 110% and after a moment the stream starts to lag and fps is slowing down. I also tried using Chrome but with no difference. Flash player is the newest version 11.9.900.117.
Any ideas on how to fix this?

i think its the best to hit the report a problem button in safari, since its appears since i updated safari to 5.1.4! maybe they make a additional update

High CPU Usage with Flash Player 11

I am not sure what the problem is but ever since I had those issues I went back to flash archive and installed a previous version that did not come with the flash plug in and I never had any problem with it since I am currently using the Adobe flash version 10 plug in with an adobe flash player active X. and I find out it was the new flash plug in that is the issue it suck all your ram. If you get some people who is having the same issues where flash player is duplicating and eating all their ram then ask them to try the version 10 plug in with the flash 11 active x it will work fine. I tried to run the version 10 flash as a complete set but some dynamic site that plays videos require a later version of flash active x to work and will be asking for an update however by keeping the flash 10 plug in there won't be any other issues. Adobe need to find out what is wrong with the new flash plug in and run a comparison with the flash 10 plug in. I hope this will help some user to get over the issues that made my online experience a nightmare for a while too.

The best way to get a resolution is to address your individual issue. Your complaint is that RAM usage is high, which is unrelated to the thread from the guy on Mac that was seeing High CPU usage on high definition video.
In order to fix the issue that you're describing, we need to be able to reproduce it. Please provide the information below, and the results of the basic troubleshooting steps as you work through them. This will help us narrow down the root-cause, and allow us to find comparable hardware in our compatibility lab to reproduce the issue with.
Basic Troubleshooting Info
To help troubleshoot we'll need the following system information:
- Operating system
- Browser
- Flash Player version - http://helpx.adobe.com/flash-player/kb/find-version-flash-player.html
- Antivirus/Anti-Malware software and versions
The first step is to work through the video troubleshooting guide for your operating system, here:
- Windows - http://helpx.adobe.com/flash-player/kb/video-playback-issues.html
- Mac - http://helpx.adobe.com/flash-player/kb/video-playback-issues.htm
When reporting issues with video or audio, it's also helpful to get your system hardware and driver details. Instructions for finding this information can be found here:
- Windows - http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_For_Windows_users
- Mac - http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_For_Mac_OS_users
Finally, sometimes video and audio problems are caused at a lower level and not directly related to Flash Player. I recommend trying both of the links below to see how they perform. If the problem exists with both, then Flash Player is most likely not the culprit as the HTML5 video link does not use Flash Player when playing. You can verify this by right clicking the HTML5 video and looking for the words "About HTML5" at the bottom of the menu.

Incredibly high CPU usage with Flash plugin

Hi all,
I'm using Safari 4.0.3 with the last Flash Plugin version (10.0.32.18) that I just uninstalled and then reinstalled, and I got an incredibly high cpu usage while viewing an Youtube video.
Here is a screenshot of Activity monitor that shows you the percentage.
http://img256.imageshack.us/img256/7186/schermata20091106a13590.png
Sometimes the Safari process reach even 50% while the FlashPlugin one runs at 110%-120%.
Is that normal? With other browsers like Camino or Firefox, the CPU usage for the same video drops to 50%-60% max.
Thank you,

Skype 4.2.0.11 has abnormally high CPU usage while...

Skype 4.2.0.11 has abnormally high CPU usage while idle.
I can't get my laptop under 70 degrees celsius unless I cpulimit or quit skype, and cpulimiting it actually makes it completely unresponsive, as if some other thread is constantly generating a lot of work and taking priority over the UI thread.
What the heck is skype doing? (And why do any of its threads need nice -10?) It takes up more CPU time than pulseaudio, truecrypt, and deluged combined.
Its CPU usage is constantly between 5 and 50 percent*, it's absolutely horrible.
*While idle. I'm unable to make calls.
I know this is expected from a linux user, but for all I know, Skype is malware. It's not open-source, so I can't find out for myself, and there are no open-source alternatives so the frankly shameful amount of bugs I encounter in Skype will never be fixed.
There are several bugs I'd love to be fixed in Skype, but first, PLEASE, optimize your code. It's absolutely horriffic at the moment.

Attached are statistics from my desktop over approximately a 24 hour period for the processes shown (other than firefox and adb).
Pulseaudio tops skype this time but that's because I've had music playing through mpd for a few hours. Skype uses more than 16 times the CPU that pidgin does, and almost double the RAM! RAM isn't shown in the screenshot but take my word for it. Bear in mind that I haven't taken (or made) any calls in this period of time, and pidgin has been signed into three different services and using encrypted chat.
I really wish that at least the protocol would be documented so someone could work around this, at the moment I don't think the guys writing skype realize just how unstable the linux port is. At least it's better than the Android port.
[Edit for those unfamiliar with linux processes: "TIME" is the cumulative time that the program has been scheduled for on any core, effectively making it a measure of total CPU usage for a given time period]

High CPU usage when playing flv files with flash

As 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've been doing research about this excessively high CPU usage problem (100%!) for weeks because I have also experienced it with my vista home premium laptop. Just recently, I have finally found the solution. The problem is not your browser or your OS or your pc's memory. The problem is caused by authorization for flash player.
Read the link (posted below) carefully and follow the steps accordingly. If you have already done steps 1 through 6 with your computer, you can go straight to step 7.

PS: I am not the author of that link, so please thank the respective site owner if you find the procedure very helpful.
Please let me know also if the link solves your problem. I am sharing this because Adobe seems unable to provide solutions to this, and I don't want to hear people suffer.

[help] high cpu usage with flash (Hello adobe developer)

Running youtube or facebook games, here's what I found. CPU usage rises to 90-100% or 90-100 % of a core.
Tested in XP32/Win7 64. Clean setups. Tested with Flash 9, 10, 10.1 rc's. Used uninstallers, reinstalled and so on. Googled on this, read many threads, such as granting permission on several files. Tested with IE, Firefox, Chrome. SAME stuff. Tested on an e8400 with P35 chipset, i3 530 with P55 chipset, e7400 with nvidia ion chipset, tested with 7[3|6]00gt's, gts 250.. So yes, I've tried a lot of things. And many different drivers too. I am now only pointing fingers at flash.
PC gets sluggish, laptops run out of battery fast. I can usually fix a lot of technicals issues on my own, but I'm TOTALLY stuck here. I should also add that, cpu usage rises only when there is motion. I can watch an .avi movie or play some 3D game, and they won't suck the cpu totally. I can remember in the past, flash won't do this. Flash won't drag the system down. Something is SERIOUSLY wrong.
Can an Adobe dev comment please?

I find it strangely odd that you've never seen this phenomenon, but at least you must have heard of it. Google flash high cpu usage. Facebook games flash lag. Or something alike. Mind moving my thread there? So there won't be a dupe thread.
I posted a similar thread in mozilla forums to see what they have to see, since i notice lag is more apparent in firefox than in ie, although both hog up cpu.
As you can see, I'm not alone.

My installation _of_ what? Let's see, I tried to replicate this in the most bare environment. With nothing else installed, and default Windows 7 drivers, I installed flash from the web, plugin only first, then activex, did the testing, same stuff. Installed OLD 183 drivers, tested with 197 drivers, then 256 beta drivers. Same deal.

High CPU usage Adobe flash player 8, 9 or 10

High CPU usage (more than 100%) while running video applications

Hello everyone,
I desperately need help with this.
I have a late 2007 White Macbook running Mac OS X 10.6.8 :
Model Name:          MacBook
Model Identifier:          MacBook2,1
Processor Name:          Intel Core 2 Duo
Processor Speed:          2 GHz
Number Of Processors:          1
Total Number Of Cores:          2
L2 Cache:          4 MB
Memory:          3 GB
Bus Speed:          667 MHz
The issue that I am having is, whenever I play a video (Netflix/Silverlight player, YouTube, Skype, etc.) the CPU usage shoots up above 100% and the video or the video chat becomes VERY choppy. It becomes impossible to keep going once that starts. Originally I had 1Gb RAM (512 + 512) ... then I upgraded to (1GB + 512mb) ... it was fine for about a year and then started chocking on memory... so recently I made it (1GB +2GB) and that's when this high CPU usage thing started (according to my knowledge)
I have had this machine since last 4 years and its very dear to me. I dont wanna buy a new one. I will really appreciate if someone could help.

I am spending sleepless nights, researching for a fix. From what I found so far, a considerable amount of people were able to fix this issue by simple cleaning the insides of their machines using air dusters, especially the fans. I don't know how cleaning would help with CPU utilization, but by interpolation, I feel it's worth a try. At least it will be clean, if not perfectly functional. lol
Now the next big challenge ahead of me is getting the screws on my Macbook open. I was following the Fan Repair Guide on ifixit.com. I went and got the #00 Phillips screwdriver as suggested in the guide... came home and found out the screwdriver is too big.... went back got a #0000 Phillips (I also found out that screwdrivers with same number might be of different sizes in different stores)... got a couple of screws out and then--- another road-block!! there are a few extremely tiny Phillips screws on my macbook. Now I am hunting for the smallest Phillips screwdriver in the world. Hopefully, I will find it in some watch repair or eye-glasses repair kit in a store such as CVS or Walgreens... aaaah... this is sooo frustrating!!! I just want to get his done so that I can check it off the list of probable solutions that I want to try. Will update here if this works.
From what you say, I think that the Silverlight upgrade might be the culprit in my case too. But the effect is there also for Youtube, Skype , or any other Video/Graphics intensive application that I use. Although, Silverlight/Netflix performs the worst among all the apps.
I love my Macbook... don't want to part with it.

High CPU usage when graphics card is put at work

I have a 13inch Air with 2GB RAM and 256GB with Windows 7 Ultimate 64bit. All possible updates have been installed.
I noticed some tearing when trying to move program windows across the screen so I started checking the CPU usage. I saw that it is spiking to 25-35% when moving a window across the screen.When you drag down a window you can see the different copies of the top bar across the screen. Not smooth at all like on a standard PC windows system. Same issue when scrolling through webpages which spikes the cpu
I also noticed a high cpu usage when playing mkv files 25-30% while on an Atom HTPC i get a lower load playing the same file. The Air should be faster than an atom with a nvidia 9400m when playing video files.
I already tried updating the nvidia files to the latest version on their site by hacking the driver inf but this did not resolve the issue.
Has anyone experienced the same or know what could be causing the beavior?
Many thanks

Maybe my initial post was not clear so let me add some clarifications.
I have the problem with Aero disabled
I have the problem on the Apple site which does not have any flash content.
I have already hacked the lastest nvidia drivers to get them on my system which did not change anything. Can you provide a link to some other 'supported' beta drivers?
I am using the new 13 inch air so it has the newer graphics card so I would expect it to be faster than an old HTPC with a 9400m in it. I wasn't stating that my Air had a 9400m.
It would be great if someone you also do the test to check the cpu load:
- when playing a 720 mkv
- when dragging a window across the screen
Just open task manager and see if the CPU spikes.
Many thanks!

Yet another high cpu using flash issue

Salutations. What I'm about to tell you won't come to you as a surprise as there have been many similar topics discussed here. In fact, on the first page, there were two. So let's get on with it!
hp pavillion entertainment notebook dv6 e2170ee
windows 7 64bit
6gb ram
intel core i7 cpu q 720 @ 1.60 GHz    (never overclocked. don't know how to)
nvidia geforce gt 230m
firefox is on safe mode. kind of better than regular mode.
firefox waaaay better than chrome in handling flash. haven't tried it on ie. don't want to. i left ie8 at version 8
flash hardware accelration is off
firefox hardware accelaration is on
latest flash player enabled
latest shock player enabled
latest flash director enabled
latest firefox
no idea if my vents and cooling system work properly. read several posts about this issue being related to hardware.
i have updated my drivers using hp support assistant, driver detective, and windows update. wouldn't be surprised if there was a conflict with all this nvidia driver as well. went to the site. it detected my model and sent me the driver. had audio and video options in it.
while writing this post, the adobe tab + 4 flash tabs off the same site (youtube, younow, cam sites, etc) are open.
performance tab in taskbar says
flashplayer 15 *32bit (2 processes with the same name but diff cpu usage by the way. why 2?) is using 5%
firefox *32 bit is using 5%
audiodg.exe is nowhere to be found
now firefox and flashplayer keep alternating ofcourse. flash always ends up with higher cpu when everything breaks. i have noticed that even after closing ff, ff and flash are still in the processes table. they stay there for a bit. why?
ISSUE NUMBER 1: i can't play a video and have flash players on at the same time. I'd like to watch a movie and every now and then look to my other screen to see what's going on with the flash site. it can't be done. all is well at the beginning then it goes to hell. i have the latest free version of bsplayer and videolan. Yes vlc handles better but it all goes to hell in the end. sometimes the video won't even show on vlc; only audio
ISSUE NUMBER 2: i don't understand the logic behind the increase in cpu. if i have 6 tabs open all flash all is well. but at some point it just spikes up. so i always try to keep the number of flash tabs as low as possible. sometimes 4 are no issue but 5 are a big issue. sometimes closing a tab helps and sometimes it doesnt.
ISSUE NUMBER 3: audiodg starts using more than 2%. It can go up to 11 or 13 even. That shouldn't happen. I've been told that for it to go beyond 2 or even 3 means there's a conflict. I had trouble dealing with this issue. I don't know what or where the conflict is. So if there's anyone here that's good at this please contact me. Ill post a pic of device manager. For the sound, i have 4 nvideo and 1 idt audio codec. I cdon't know which to disable or uninstall. im thinking of unintalling every audio/video driver i hav and start from the beginning. BUT LETS NOT MAKE THIS ABOUT AUDIO/VIDEO CONFLICT
QUESTION 1: was there ever a time when this issue didn't exist? perhaps there's a "stable" version of ff or flash that don't cause this.
QUESTION 2: ive seen a lot of posts about this but I honestly can't remember any participants saying OH REALLY? ODD, I NEVER HAD THIS ISSUE BEFORE
QUESTION 3: isn't there some kind of tracer that can track the moment that it goes to hell? im sure there is but no one's mentioned it so far
QUESTION 4: would buying a new laptop solve this? I'd like to think not since the issue is flash not the capabilities of a laptop but i can't help but think that a better laptop will fix this. My laptop is 4 years old.
QUESTION 5: i don't know anything about multithreading or multiple cores handling a single process but if someone showed me how, would that resolve my issue?
MY WISH: for flash to coexist peacefully with human beings

Disabling Hardware Acceleration in Flash means that we're doing all of the processing on the CPU, instead of on the GPU. The GPU is purpose-built for 3D graphics and video decoding and is far more power efficient. Decoding H.264 video in software is very CPU intensive, which is why we made the huge investment to enable hardware acceleration on the vast majority of available desktop hardware. Running six CPU intensive tasks simultaneously (which is what you're doing by using six simultaneous tabs) is unsurprisingly going to tax your machine.
If you've disabled Hardware Acceleration because video wasn't working right or something, figuring out how to get that enabled (or moving to better hardware with good driver support) would solve the vast majority of what you're describing here. If HP doesn't offer updated drivers, I'd recommend trying the corresponding Nvidia drivers, as OEMs aren't always motivated to pick up the latest fixes once a model is no longer generating new revenue for them. The chipset manufacturers tend to provide longer support, but those drivers aren't officially supported by the OEM.
The architecture for Protected Mode for Firefox is a result of the fact that we've retrofitted a modern plug-in security approach to a legacy plug-in architecture. As you've noticed, equivalent sandboxing in other major browsers is designed into their plug-in architectures, and is therefore more efficient. We've made huge investments to support modern security architecture and always do our best to accommodate efforts from our partners in the browser space to further secure the browser. You can find a detailed explanation of our approach to Firefox here: Inside Flash Player Protected Mode for Firefox
Firefox controls the instantiation and destruction of Flash instances. You'll also notice that Firefox hangs out for a while after shutdown. This is something that we're aware of, but it's beyond our control.
Flash doesn't have much to do with audiodg, except for the fact that it generates sound and uses the windows sound subsystem. This article seems to present some reasonable advice in resolving issues with high CPU consumption from the sound subsystem. Fix Audiodg.exe High CPU Usage in Windows 7 | Windows EXE Errors
Hardware accelerated video encoding is typically not available on consumer-grade hardware (primarily because of the difference in licensing models for encoding and decoding with popular commercial codecs), and therefore is done on the CPU. The particular website chooses what codecs and bitrates are involved, and higher quality feed will consume more CPU. It's also worth pointing out that not all video can be decoded in hardware. We provide clear guidance to content providers on how to encode video so that it can be played back efficiently, it's ultimately up to the content provider to follow that advice.
So, long story short, each tab consumes resources. Running a single tab is going to use less resources than running multiple tabs. The latest version of Internet Explorer does some stuff to reduce resource consumption in tabs that you're not actively looking at. We're discussing possibilities with the Chrome folks for doing the same thing in Chromium-based browsers. Mozilla isn't interested in investing in browser plug-ins, so we don't expect to see the necessary browser-side improvements there. The Chrome sandboxing model is more efficient that protected mode for Firefox, so tasks that require moving a lot of data (like streaming video) may use less CPU in Chrome.
To answer your questions specifically:
1.) There was a time before we supported multiple tabs, webcam streaming, H.264 video decoding and modern security sandboxing. I wouldn't recommend using those versions.
2.) There are a few posts about this, but we have ~1.5 billion users. The majority of the very small number of folks relative to our install base are complaining their machines are overheating, which is a symptom of an ineffective cooling system.
     There's nothing magic about Flash that causes it to somehow superheat the CPU.
     There was a time before tabs, where people didn't normally run 5-50 browser windows. Websites also got much more complex, and the security threats got far more serious and complex.
     Playing video as a plug-in in the browser as opposed to something like VLC is inherently less efficient, as pretty much each pixel and packet gets passed through the browser before it gets to the OS or drivers.
     All of these things require additional processing. The resources on your computer are still finite, and there is an upper limit to the number of simultaneous tabs you can use.
     At some point, you come to a juncture where you need to decide between throwing more hardware at the problem, or using less tabs simultaneously.
     Also, most laptops have power saving CPUs, so they'll ratchet the clock speed down to save battery. You might want to check your power settings to make sure you're running at the CPU's full capacity when plugged in.
3.) Not that would generate anything really useful.
4.) Possibly. You actually already have a multi-core machine. I think you'd get more bang for your buck by enabling hardware acceleration and switching browsers.
5.) You already have a multi-core machine that we support.
Your Wish: We're constantly addressing security issues identified through our own testing, emerging research and intelligence from our partners in academia, government and industry. We're also looking for opportunities to tune the player, but the reality is that Intel, Nvidia and ATI (and a long list of others, in addition to Adobe) have tuned Flash Player extensively for their hardware. We work closely with the Internet Explorer and Chrome teams to continue to make the Flash experience better, and are always happy to work with the Firefox team should they decide that they're interested in plug-ins and the desktop browser again. At the end of the day, Flash is just a low-level runtime. It's just as possible to write inefficient ActionScript as it is to write inefficient C++, and while we provide some fantastic tooling for profiling your Flash content, it's up to individual content providers to write efficient code. It's really difficult to find opportunities to make generic optimizations that don't break a percentage of the hundreds of millions of sites published with Flash content.
I'm actually still not clear on what the problem you're experiencing is. All software running on your machine that's actively processing something is going to use a non-zero percentage of CPU time. The symptoms you describe indicate that Flash consumes 5% of the CPU, which is totally reasonable. I'm guessing that I don't have the complete story.

Flashplayer h.264/mp4 high cpu usage

I can watch my TV-quality h.264/mp4 640x480px / 25fps videos
in fullscreen
(encoded in MPEG Streamclip, multipass, b-frames,
deinterlaced)
on my seven years old G4 Digital Audio, 466 Mhz without any
dropped frames.
As long as I use QuickTime, I can do that.
On the other hand the same video plays less smooth on my G5
Dual 2.7 Ghz
if I watch it in the flashplayer (newest update...).
I just wonder, if Adobe realizes that they really should work
on
the high CPU usage of their flashplayer while playing back
h.264 videos.
Or is this the price for the smal flashplayer size and can't
be changed?
After doing several tests, I am afraid TV-quality h.264/mp4
vidoes do stutter for about 50%
of the current online viewers.
Does anybody know, if the developers at Adobe are working on
that?
Thank you for any replay

I think part of the problem here is that flash allows to
compose additional graphical elements onto the video. So it has to
do colorspace transformations and scaling in software.
Recently I ran OProfile while watching a flash video (not
H.264) and found that it spends a significant amount of time in a
routine that does BGR32 to RGBA32 conversion. For fun I tried to
write a faster version and ended up with a MMX version that is 40%
faster and a MMXext version that is 67% faster. For reference,
plain memcpy is 44% faster. (all values for memory blocks >>
L2 cache, MMXext can be faster than memcpy because of
prefetchnta/movntq).

Continuous Audio, Jerky Video, High CPU Usage

Hello,
I've been browsing the forum for a while and tried a few searches. I found some problems similar to mine, but nothing with a solution that worked. Here is my situation. I was running Windows XP Home SP3 with the latest IE, Firefox and Chrome browsers. I updated my flash player (to 10) and I hulu didn't work any more. The audio would play but the video would freeze and change to a different frame every now and then, usually a couple minutes behind the audio. I had already decided that I wanted to switch over to Ubuntu 10 so I just did a fresh install. I updated everything over night and then I tried to watch hulu using the latest firefox. I had the same problem. The audio will play, but the video freezes. I downloaded the latest Chrome. Same problem, both with high cpu usage. I am using a Dell Inspirion 2200 with 1.5 ghz cpu and 512 mb ram with integrated graphics. So far the only thing I've tried is disabling hardware acceleration. My internet connection is 1.5 mb. I would really appreciate any help.
Thanks,
ralphcholo

I noticed it's the "audiodg.exe" program that is acting weird with high cpu usage. Some tutorials say to disable 'audio enhancements' but I can't find that option available in windows 10. In device manager, I notice 2 separate audio drivers. The Acer download page only has 1 realtek audio driver. I'm wondering if there is supposed to be another driver to update? My audio seems to be working fine without this problem coming back. I've attached a screenshot showing the 2 different audio fields in device manager. The bottom one is the driver listed on the Acer driver page, I'm not sure where the other upper audio driver is to download.
