Disable Hardware Acceleration in MacOS VM

I need to test Flash Applications with different system configurations. For that reason I use MacOS VMs to cover a lot of constelleations.
Hardware acceleration is not possible. In Safari and Chrome it will run properly anyway but not in Firefox.
Only a black / white placeholder is showing up and I don't get the settings menu to disable the hardware acceleration. I tried to disable it somehow with the flash player debug version and mm.cfg, but it doesn't seem to have any option to disable hw/a.
Does anybody have an idea how to disable the acceleration ?

There's not an mms.cfg directive to disable hardware acceleration.
The preference file that controls the Hardware Acceleration preference that gets set via the Settings UI is shared between Safari and Firefox (Chrome has it's own thing going on). If you unset Hardware Acceleration in Safari, and you're still seeing the problem in Firefox, something else is wrong. I'd recommend filing a bug if that's the case.

Flash Player refuses to make "display" tab available in settings; cannot disable hardware acceleration.

Windows 8.1 64-bit laptop. Multiple Flash Player issues. (1) Sites say I do not have Flash Player installed but Adobe download page says I do. (2) Right clicking the test video, or any other video, give access to "settings" but there is no display tab. (3) Some video sites suggest watching in HTML5, which does work, but most simply present the green screen. I have spent the better part of three days reading every forum I can find, and they all point to disabling hardware acceleration, but I cannot access it. None of the recommended fixes work.

HI ,
Please provide the following information :-
1)Snapshot of your "Flash player Settings " ..
2) Url links for which you are facing the green screen issue .
Also ,please provide additional information like GPU card information,browser version information and flash version

Once firefox 4.o was installed, full screen video produced white screen. Had to exit and and restart video. Using a mac os 10.5. Disabling hardware acceleration did not fix. went back to firefox 3.6 and all is ok. Any help would be appreciated.

Once firefox 4.o was installed, when switching to full screen while watching any internet video produced a white screen but audio still playing. Switching back to small screen has a still video but audio still going. Had to exit and and restart video or open a blank new new tab then delete it and then small screen video would play. Using a mac os 10.5. Disabling hardware acceleration did not fix. went back to firefox 3.6 and all is ok. Any help would be appreciated.

Your hardware was never designed to run that old a version of OS X, it's best to update the application or find another application that is more up to date. Installing Leopard simply will not work on your system.

Flash Player - Disable Hardware Acceleration - Apple TV-Mac OS 10.4.7/Firefox

Hello all,
I have been going down a fun path getting my 1st Generation Apple TV (160 GB HD) to run Hulu natively (without PlayOn restreaming). After fun times getting Firefox and Flash Player working, I blasted through setting up Hulu Widget to keep the video size small (Apple TV in 480p defaults to an 800x600 res).   Things look pretty good. I maxed out buffering/cache for all Hulu related sites within Global settings, this produced nice improvements. I found a GreaseMonkey script that forces the Flash Player to always render Low Quality video. This helps immensely at stopping stuttering with little trade off in quality. My last piece to try to tweak video playback (aside from monkeying around with the OS X kernel) is the disable Hardware Acceleration.
BUT, I am having a major problem with mouse support or something. Everytime I bring up the Display settings via a Right Click, I cannot uncheck "Enable hardware acceleration". Surprisingly clicking it 500 times still does not make it uncheck.
I have searched high and low but have not found a clearcut way to disable it via script or other non-interactive means.
I wonder if there might be a javascript that could be plugged into GreaseMonkey to accomplish the end goal.   This blog and Adobe document refer to the wmode parameter and how to use it to disable HA.

I am thinking perhaps I can take the Low Quality JS (http://userscripts.org/scripts/review/38994) and replace "quality" with "wmode". Am I on track?    It seems "opaque" might be the right one. http://kb2.adobe.com/cps/127/tn_12701.html
There is a case related to my question: https://bugs.adobe.com/jira/browse/FP-5748
Any tips, clues, pointers, commiserations?

Hi, LOL at my screen moniker. That's interesting that the FF beta has an Option for that. The only problem, is that I have heard that each browser must UNcheck the H.A. I'm sure you'll find out.
Hope that works at least for FF. Let me know if you have time.
I've been checking out Apple TV and Google TV. Just saved the links and some info, haven't had time to go further. I'd prefer Apple TV over Google tho.
I have a 55" HD Sony/Blu-ray Surround Sound Speakers, etc. I hooked up the VGA cable for Internet, and WOW on the Screen/Monitor!! Now I'm thinking about the iPhone 4 with VZ too, on their pre-order list for 2/3/11!
Hard to keep up with the Technology, moving faster today for some reason.
We are under the Snow & Ice warning, getting it now. Hope I don't lose power! If so, I'll be offline for sure.
If I find anything on that H.A. for IE, I'll let you know.
Thanks,
eidnolb

Immidiate crash of Flash, unable to disable hardware acceleration. Solved!

Flash video/content crashes instantly, so it makes it impossible to right-click it and enter the settings to disable hardware acceleration. This issue wasn't solved for over 2 years in other forum posts, but I finally did it. You have to temporarily DISABLE all your recording and playback devices in the windows' sound menu. this will let you play flash content (it did help me), just enough to disable hardware accelertion. I am suprized Mozilla survived despite being unable to debug their own software - no respect to customers ad their time.

Flash is developed by Adobe, not Mozilla. Though the good news is that Firefox is creating their own flash player that should be in a near-future version of Firefox.

Disabling hardware acceleration resolved issue with Google Maps not loading in Firefox 19

For the last few days noticed that I could no longer use Googlemaps in Firefox 19. The page would completely load then if I typed a single character into the search box for google maps it would bring up the "Still loading" text and do nothing.
Followed a couple links on the Mozilla support page and started Firefox in safemode. Maps was speedy and worked fine in safemode. I started again without safemode and tried the simplest step to see if it would resolve the issue and disabled hardware acceleration. All of a sudden maps worked again. The strange part is when I re-enabled hardware acceleration maps continued to work (go figure, makes no sense to me).
Just wanted to post my experience for others who may be having a similar problem.
System is Windows XP 32bit
Cheers.

Thanks for posting your solution. For other users who may find this thread and need more information, see:

Cannot disable hardware acceleration in firefox.

Hi.
I am unable to disable hardware acceleration in Firefox using Windows 8. I can open the settings, uncheck the box, but this does not change anything. If I open the settings again the box is still checked. This problem does not exist in Chrome. Anything I can do to fix it?
Thanks for any help
Owen

There are two places to disable it:
Firefox (This is on my Mac, but it's the same for Windows. Tools>Options>Advanced>General)
and Flash

Disable hardware acceleration programmatically

Hello,
Nowadays number of devices supporting flash is quite huge, however some of those devices do not support right clicking.
End user experience is also getting very important, so I want to understand if it's possible to disable flash hardware acceleration programmatically? (using actionscript, external SWF or executing Cthulhu summon procedure
I want to be able to disable hardware acceleration with simple checkbox. I googled this a lot, however I couldn't find any solution for this.
anyone?

hi,
i've tried all possible wmode options, however they don't really affect the video playback problem I am facing. the only way to fix it is to disable hardware acceleration in flash settings.
to be frank, I find current situation quite irritating - every service providing video experience to the users via flash is having special page containing advices for HW acceleration disabling:
vimeo: Playback Issues on Vimeo
youtube: https://support.google.com/youtube/answer/1230977?hl=en
hulu: http://www.hulu.com/help/articles/166587
etc... millions of them
and the only way to disable hardware acceleration is to go to the flash settings and disable it manually.
I wonder if there is anyone from Adobe reading those topics? For the last two weeks I googled a lot this topic, people like me are trying to provide best user experience, but they can't. I found similar to this topic even on those forums. The author also had to go for the manual 'resolution' approach. Come on guys, this is 2014, there should be more smarter ways doing this like providing actionscript methods for changing this option.

Green screen of doom / no disable hardware acceleration

I have a PC
Windows 8
Problem # 1: I am watching youtube. After a while, the screen becomes green. The only way for me to temporary fix ths problem is to restart my computer. But after a few more minutes, the green screen of doom comes back again!
Problem # 2 : Everywhere on the internet (including adobe), they say to go to settings > disable hardware acceleration. My settings doesnt have the display panel in settings and i cannot disable the hardware accelerator. In my settings, i have: privacy / local storage / microphone / camera. -- no display panel to disable hardware acceleration!
Picture: http://img708.imageshack.us/img708/6821/greenscreeen.jpg
Problem # 3 : I cant email adobe for help at all. It just takes me to a faq help page which doesnt say anything to help my problem!!!
Can anyone help me? This green screen is very frustrating!!! The only way to watch videos on youtube to take out the green screen is to downgrade the video quality to 240p (which sucks by the way!!)
Please help me.

I have found the solution to my problem, if others need this information.
I was using Internet explorer.That was the problem. I dont know why, but internet explorer doesnt have that tab in its settings to disable the hardware acceleration.
Solution:
Download firefox. They have that tab to disable hardware acceleration. I didnt have any green screen problems after.
I dont know why any tech specialist here couldnt tell me this simple piece of information before.
I had to find it out for myself...
Such a simple solution to a simple problem...

How to play Youtube/Hulu videos without disabling hardware acceleration

I have the Acer AspireRevo AR3700 nettop computer. I cannot watch any Youtube or Hulu vidoes without disabling hardware acceleration. I hear sound, but I do not get any video; all I get is a black screen.
The computer has the latest Nvidia Ion processor. One of the major selling points of this computer, along with this particular GPU, is that it can play videos WITH hardware acceleration.
I have searched far and wide on the web and the only solution I can find is to disable hardware acceleration. Unfortunately, that defeats the purpose of having the Nvidia Ion GPU.
Please advise me on how I can get the videos to work without having to disable hardware acceleration. I DO want to take advantage of hardware acceleration, so please do not tell me to simply disable it.
Please help.

The native Android Youtube player does a much better job of handing video playback than embeded flash in a browser.

Disabling Hardware Acceleration via code

Is there a code snippet, or script, to disable hardware acceleration from a flash website on multiple machines?

I don't think there is such an option, at least on Windows there isn't (it must be set manually for every user on the system).
However, there really should be such an option, e.g. in the mms.cfg file.
It would be great if you could issue a feature request for this at https://bugbase.adobe.com/

Disabling Hardware Acceleration Globally

Just curious if anyone knows how to disable hardware acceleration system wide on Mac OS X 10.7.3? We have graphics issues on about 150 of 300 iMacs where it distorts and takes the entire machine down. After a few weeks of troubleshooting we were able to nail down that it is flash hardware acceleration that is causing the issue. Now we have to apply that setting to all 150+ computers.
Any help would be greatly appreciated. Thanks.
Chris

Disabling hardware acceleration

I can't seem to be able to do it. I right-click in a Flash game, click Settings, but I CANNOT uncheck the box. This happens in IE11 and Firefox. I CAN do it in Chrome.
I want to try a trick I heard about when playing certain Very Flash-heavy games like Farmville 2. Others have said to disable hardware acceleration, but Flash won't allow me to do it in certain browsers.

Adobe Flash crashed so I disabled hardware acceleration

I guess so many people are aware of that problem.
When exiting a fullscreen video, flash player crashed. So I looked at the solution in this site. It told me to disable hardware acceleration. If it worked I am supposed to upgrade my graphic drivers but it is already up-to-date. I don't want to keep my hardware acceleration disabled but when I enable it I still have some problem. Help me!
Thanks

There are many problems with Flash player 11.3 right now. Unfortunately, at this point your best solution is to leave hardware acceleration disabled until Flash 11.4 comes out, then update and try again. I'm sorry I don't have a better answer.
