Hardware Acceleration for Linux with FireFox 4

'''Is this just a myth?'''
I am using Ubuntu 10.04 64-bit and FireFox 4 stable with a GT 240 and the latest nvidia binary driver. I have this set up as a HTPC through HDMI cable and have audio as well through the HDMI. It works wonderfully! I can watch x.264 and my intel celeron 2.8 GHz doesn't even get out of bed thanks to hardware acceleration.
Now, that is NOT the case while on the web... It is a tall order to watch HD quality flash (although with the [http://demos.hacks.mozilla.org/openweb/HWACCEL/ mozilla hardware stress test] I get 45 FPS). It seems to be that hardware acceleration is still very much in its infancy in the linux environment with firefox 4.
After searching through many threads I have come to find some useless information.
''MOZ_ACCELERATED=1 MOZ_GLX_IGNORE_BLACKLIST=1 firefox'' - does nothing
''layers.acceleration.force-enabled=true'' - does nothing
There seems to be an issue with firefox not recognising the installed graphics card. On Windows machines, the about:support page will report all the graphic card information in the Graphics section in addition to '''GPU Accelerated Windows 0/1''' or '''1/1'''. This seems to NOT be the case in linux. Why? Why doesn't firefox discover the installed graphics card?
Now, if I have missed a memo or been a total newb in this attempt to take advantage of Accelerated Hardware in FireFox 4 for linux '''PLEASE ENLIGHTEN ME''' as to what I need to do. If I have done all the things needed to achieve hardware acceleration and it is just not possible, than the good 'ol folks at mozilla should be a little more transparent when they proudly proclaim that they have released a hardware accelerated browser.
If anyone can shed some light on this predicament please post. If anyone has hit the same wall as I have please post... rant... w/e...

Finaly. How to enable hardware acceleration for X-

After much discussion on this form and with my friends, I've finally cracked hardware acceleration for X-FI on Vista. It works by using Alchemy on a large scale and gives acceleration for everything you listen to. The breakthrough finally came through thanx to help and info I received from alexs3ds on this thread?http://forums.creative.com/creativel...message.id=645?It started as an emulation concept discussion and evolved in to this. It gives all your 3D audio effects and EAX in games without game by game transmutation and I have noticed a large quality and volume enhancement in normal music and film audio because even that is now accelerated. Here's a step by step guide on how to do it.[color="#ff0033">?[color="#3366ff">Download Alchemy and install. Get it here .[color="#3366ff">http://preview.creativelabs.com/alchemy/default.aspx[color="#3366ff">?[color="#3366ff">Open a?window in explorer and go to [color="#3333ff">Windows\System32.[color="#3366ff">?[color="#3366ff">Locate the file dsound.dll and right click on it then select properties.[color="#3366ff">?[color="#3366ff">Click the security tab then click advanced.[color="#3366ff">?[color="#3366ff">In the advanced security panel?that opens up, click the owner tab then edit.[color="#3366ff">?[color="#3366ff">Use this to set your user account name as owner.

Reboot your computer and you are now using hardware accelerated sound. ?[color="#ff0033">IMPORTANT NOTES YOU MUST KNOW[color="#ff0033">?This only supports 6-Bit samples. You can't use 24-Bit audio samples. You can however reverse the process and regain support. The Alchemy drivers can cause a bit of choppy sound now and then if you don't configure them right. See the Alchemy advanced FAQ for info. Plus, remember they are Beta. You can however update your system as and when alchemy updates. It's not known if every game will work with EAX or 3Dsound with this. To my knowledge?all, if not?most do.You can still edit and add game settings to the dsound.ini file. For help and info in getting the best quality out of your X-FI and a list of what XP software you can install off your driver disk that came with your card refer to this thread. http://forums.creative.com/creativel...essage.id=6029?Enjoy. Edit:- IMPORTANT UPDATE?This will only work if your card is set in game mode. It will not work properly in any other mode. See my post further down this thread for more details.Also important is that I have only been able to test this on Vista 32 ultimate. It is untested in any other version of Vista. Perhaps people who have it running on other versions of Vista could post this info and help put together a list. ?

It does work, however I discovered more?important conditions. You MUST have your audio card in game mode BEFORE you do this. The reason is that the alchemy file passes the audio to OpenAL in game mode only. IF YOU TRY TO RUN GAMES IN ANY OTHER MODE YOUR SYSTEM WILL CRASH WITH BSD. IF YOU TRY TO RUN MEDIA PLAYER IT WILL HANG. IF YOU RUN DIRECTX DIAGNOSTIC YOUR SYSTEM WILL CRASH WITH BSD. YOUR?CARD MUST BE IN GAME MODE. IF YOU TRY TO CHANGE TO GAME MODE AFTER THE SWITCH, YOU WILL NOT BE ABLE TO AS THE AUDIO PANEL WON'T LOAD. DO IT BEFORE YOU SWITCH. As for windows replacing files after reboot, that aint happening to me. I've looked everywhere and can't find any sign of?were replacement files would come form either. Not that I'm saying it isn't happening, Vista is supposed to have a security system that stops you from replacing core system files. It just ain't happening in my system. However, I do have various system hacks in place and one of them may be stopping this. Need to look in to this. Fact:- I'm sitting with this in system now ( got no intentions of going back cause the audio's great ). I've tested 0 up-to date games and all give EAX etc. Without transmutation. Audio sounds amazing compared to what it was before and video audio finely plays in sync ( hurray). Maybay I should add a warning to this mod that you must only try it if you know what you are?doing.BTW in case this has anything to do with it, my system is :-
Asus?am2 with nforce 4, amd am2 x2 dual core cpu, 2 gig dual channel ddr2 800, oem?SB X-FI and Vista 32 ultimate.

Is there any hardware acceleration for video playback

Hello,
Nice to hear about this framework
Will there be any other new features regarding perfomance and hardware acceleration for video plaback in this new framwork?
(except the existing FullScreen harware acceleration available in flash 9 )
Thanks!
Adrian

OSMF is a framework built entirely in Actionscript 3.0, which means that it can only take advantage of those features which are enabled by the underlying Flash Player. So no additional hardware acceleration. That being said, we work closely with the Flash Player team and the FMS team, so any new features they add should find quick support in OSMF.

Can't load the snag it plug in for scrolling with firefox 6.0.1. i have snag it 1.0.3

I have just purchased snag it 1.0.3 for mac. It has a section in the install for loading the plug in for scrolling with firefox. It errored and said it can't load the plug in with firefox 6.0.1 version. What version needs to be in order to use the scrolling feature?

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:

How can I open hardware acceleration for safari 5.1.1 in Windows 7?

It is said that safari 5 for windows supports hardware acceleration now. But I cannot open this feature in my Windows 7 laptop. Is there any way to open this feature manually?

I know Safari a little and 5.1 can come to its knees easily and repeatedly.
At first I thought it lasted longer if:
disble java, plugins, javascript
run only in Private Browsing mode
disable web cache
I'd like to see it launch with cache disabled and like firefox always start in Private mode.
Plus site specific preferences
Still accepts ad and tracking cookies - must consider those to be "well you visited the site" so the site can set whatever it wants.
I'll use Opera 11.50 instead.
I tried Windows "trobleshoot compatibility" it wants to set to run it in XP SP3 mode and at the end "incompatible application".
Settings applied:
XP SP2 mode
Disable Aero (iTunes will lose video/movie Window if the desktop is locked for UAC)
I've lost all borders of windows and tabs, freezes or locks up but no sign of not responding even though I can't do anything - but I could close Windows and tabs from the Task bar.
Total PITA and waste of time as I investigate, remove and check for conflicts with Kaspersky and others.

A reasonable hardware configuration for Linux OAS

Has anyone out there tried to run
Oracle 8 for Linux and OAS 3.02
all on the same toasted PC/pentium server?
Could you tell me the nature of your
hardware configuration (processor speed, ram, etc)
if you feel the performance is acceptable for
development (not for actual business operation).
The technical FAQ lists 48 megs and any
Pentium to run Oracle 8 for Linux which
verges on ridiculously low.
I just want to know a reasonable
configuration to run both Oracle 8 and OAS .
Thanks,
Heji

I have been runnig OAS/O8 on a Pii/300Mhz system with 128mb of
ram, and so far I have no real complaints on speed. I even tuned
the SGA to give a little better performance and still have around
40 or so MB free. BTW, I haven't really tried to mess around
with the Linux version of OAS, but have used the Solaris version
previously, have you noticed any problems with the wrb starting
up? I have seen some error messages saying "No processes..." or
something, looks like an error.. have you experienced this?

Preferred Hardware Plattform for Linux RAC Cluster

What ist the preferred Hardware Platform
for using LINUX with Oracle RAC - Cluster solution ?
What do you prefer Suse or Redhat ?
Is there a tested Hardware Environment from Oracle Support ?
Thanks

You have the disk space, but not the memory, even discounting the memory for the Oracle VM hypervisor, OEL/RH5 is going to take at least 1G to run. So, with your base OS, hypervisor, Linux and Oracle (clusterware and DB), it may be possible, but I believe you would be swapping so much you would have terrible performance. I would look at a MINIMUM of 3GB if not 4GB RAM to try this configuration.

With hardware acceleration enabled, and with plenty of tabs open, using the Windows 7 taskbar preview option will almost always crashed the nVidia display driver.

Latest Firefox 4 beta 6.
nVidia GT240 1GB DDR3 with driver version 258.96.
Windows 7 Ultimate.
If I have plenty of tabs opened, in Firefox 4 beta 6 with hardware acceleration enabled, using the Windows 7 Taskbar preview feature (that will show all the tabs Firefox has loaded) will cause the Nvidia display driver to crash. When this happen, the GUI part of Firefox will be unusable and has to be killed via Task Manager.
This doesn't happen if hardware acceleration is disabled.

It is beta software and the older 4.0 b6 version may not work with all display drivers.
You can trey the test extension: http://jagriffin.wordpress.com/2010/08/30/introducting-grafx-bot/

Hardware acceleration for AVC video playback

Hello,
I looked for Adobe forum for developers but failed, so forward me please if this is not right place for the question.
We are developing a software that cuts out some unwanted scenes (such as advertisements) from a video (AVC inside MP4) with partial reencoding of the source. The result video contains some original GOPs (with a pair of SPS/PPS) followed by several reencoded GOPs (with another pair of SPS/PPS). Finally the video is played back with Adobe flash (e.g. StrobeMediaPlayback). The problem is that such videos are not played correctly with the latest Google Chrome (35.0.1916.153) and Adobe flash (14.0.0.125) on some configurations (e.g. Windows 7, 32-bit version, Nvidia card) when "Hardware acceleration" is switched on. Even if the second SPS differs from the first by even one parameter the second part of the video is not decoded. What does "Hardware acceleration" mean in this case? DXVA? Or does a browser decide what technology to use? Are there some known restrictions?
Thanks

2D GPU acceleration for Linux Reader 8 (when it will be available)?

It would be nice if Adobe Linux Reader 8 could use "2D GPU Acceleration" in Linux too. It could be done using OpenGL driver. Nvidia Linux Geforce driver has support for shader technology in Linux too. ATI also uses its own accelerated OpenGL library in Linux.
Will Adobe make Linux Reader 8 with 2D GPU acceleration?

What a pity. Adobe reader is very slow even on fast machines when compared to open alternatives. 2D GPU acceleration could give a chance to Adobe Reader to work at least equally fast as open source viewers.
However thanks for reply.

Flash Player will not install for use with Firefox

I cannot install Flash into Firefox, To see Flash content, I must use Google Chrome...no problem there. Way back when, I had no problems with Firefox.
Though I am an administrator, I get the "insufficient permissions" message just before the installation is complete. I tried everything suggested in Adobe's help area in that regard.
What I have tried: A new administrator account. Making sure I was running the .exe program and Firefox as an administrator. Delete and reinstall Firefox. Use the uninstall from Adobe for Flash, and then try the reinstall. Disabling all security while doing all of this. Installing in Safe Mode. I spend a few hours on this every month or so.
A new install in Chrome happens. I even downloaded Commodo Dragon, and have the same trouble there...I feel like Chrome is wandering around inside there to keep me from using Firefox!!! I have been using Firefox for years, and still strongly prefer it, but I am about to give up.

Could you check the progress of the install.
(1) Physical file location
The DLL is deposited in this folder:
C:\Windows\SysWOW64\Macromed\Flash
Can you find NPSWF32_11_9_900_170.dll there?
(2) Registry entry
If the file exists, the next link in the chain is the registry entry Adobe leaves for Firefox to find.
If you are comfortable using RegEdit, that should be here:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\MozillaPlugins\@adobe.com/FlashPlayer

Re-Packaged 9IASR2 for Linux with Patches release date?

Anyone have a date when Oracle are going to re-release the linux distribution for 9iasR2 with all the patches.
It took me 3-4 weeks to get everything working on Linux. I also installed the Win2K version which was very smooth. I plan to re-install on Linux but onto two boxes, one for the infrastructure server and one for the
app server because of the memory and processing requirements. I don't want to go through the pain of that linux installation again!!!!. I have several projects on hold for this, so a timescale would be very useful.

Wait until it becomes available on OTN, and then place the order.
HTH,
Ashesh Parekh
Oracle9iAS Product Management Hi Ashesh,
Have we got any update on the release date. My project deadline is at the end of the month. If the linux repackaged version is going to be later than that I will have to install on Mircosoft Win2k!
