What does 'media.windows-media-foundation.enabled' do?

I disabled media.windows-media-foundation.enabled in order to get .mp3/mp4 to stop playing in firefox, but rather prompt me to open/save as. It works fine. However, the place where I found this solution said it was going to break some embedded playback functionality.. or something.
Vimeo still works, HTML5 Youtube still works, Vine still works. I'm not sure what is supposed to break, and I *KNOW* I'm going to find it eventually and completely forget that I ever did this. Can anyone explain what is supposed to stop working?
Thanks! :)

Media Foundation is used to decode MPEG media, such as MP3 and MP4. Many sites that feature HTML5 are using alternative formats such as WebM that are not patented.
I think you might occasionally have a problem on some sites. For example, the site might only offer MPEG media in its HTML5 player and use a script that doesn't test carefully and provide an alternative (e.g., Flash player media) for browsers that do not support MPEG media. But... hopefully not too many sites.

Media.windows-media-foundation.enabled funcationality in 35.0

I want MP4 files to open in an external player. I had media.windows-media-foundation.enabled set to false but it seems that stopped working with the new release. When set to false I now get an error from the link: Video can't be played because the file is corrupt.
Any help would be appreciated.

hello tobyexx79, please set media.windows-media-foundation.enabled back to its default preference and turn '''media.play-stand-alone''' to '''false '''instead.

How to utilize media.windows-media-foundation.enabled?

I have read all the articles I can find on media.foundation. But, I do not know what firefox is looking to on the host os for the appropriate codex.
I am running windows xp pro sp3 and firefox 22. I interpret various forum questions that firefox should play an mp3 file if the os has the appropriate codex. Under windows device manager I have a registered system codex for mp3. Firefox will not play the file but rather offers to d/l it. Is Firefox looking to windows media player for this information?
I would like to know how firefox is using the media.foundation preference in order to adjust my system to it. Any help would be appreciated.

i'm not very good at the technical level but from past crash reports i know that the mfplat.dll library is called which handles the media foundation stuff...

Firefox 21 does notrecognize Windows Media Player plugin

Firefox 21 on Windows 7 x64 Home Premium.
1.
I am a regular watcher of the Israeli TV at http://www.iba.org.il/. This was working fine until a couple of weeks ago, when I started getting prompts that a plugin is missing.When I click on the prompt to get the plugin, I am told it is unavailable and I am asked to get Windows Media Player 11 plugin manually. I downloaded and installed it a couple of times, but it does not appear in the FF plugin list.
There have been no changes on my laptop.
2.
Another problem seems to be that each first search I do on Google, I am getting some page that is trying to sell me something; the following searches are OK. I figured some malware/hijack but several security programs have not found anything.
Please advise. Thanks.

There has been a change in where Firefox searches for plugins and the plugins folder in the Firefox program folder is no longer scanned for plugins, so Firefox won't find them anymore if they are installed in the plugins folder instead of the "browser\plugins" folder that Firefox now scans.
You can set the plugins.load_appdir_plugins pref to true on the about:config page to make Firefox scan the "<install>/plugins/" directory for plugins like the WMP plugin (np-mswmp.dll).
You can alternatively move plugins from "<install directory>\plugins\" to "<install directory>\browser\plugins\" to make Firefox find them again.

FCP to Compressor meltdown: What does "User aborted Media Server" mean??

"Final Cut Pro generated an error or unexpectedly quit User aborted Media Server"
That's what I get every time I try to export an MPEG-2 from FCP via a Compressor QuickCluster. Always worked in the past, never works now. I don't recall changing anything. Anybody ever seen this before?

I FOUND A SOLUTION TO THIS PROBLEM.
I followed Apple's troubleshooting article: http://docs.info.apple.com/article.html?artnum=302845
And the last step finally fixed the issue. That is, manually uninstall all Compressor and Qmaster application files and reinstall Compressor and Qmaster from the FCS2 discs. Then run Pro App updates. Everything is running smoothly now.
This process does however introduce a new bug in Motion, but I found a way to fix it here:

.mp4 video's audio won't play on Firefox, even with Microsoft Windows Media Player Firefox Plugin 1.0.0.8

Title says it all: trying to play any .mp4 video files, or anything that utilizes .mp4 files period, will have the video play just fine, but with absolutely no audio at all. I run a Windows 7 Home Premium, and have tested several sites that utilize .mp4 video files, and have tested it on Internet Explorer, with Explorer showing better results at playing both the audio and video.
I have checked to see if media.windows-media-foundation.enabled is true in the about:config menu, and restarted Firefox, but to no avail. Any ideas as to what could be the root of this problem?

Hi Soundless_Cyborg,
Can you please specify an example url where this is happening, sometimes the video player does not support the codec.
Maybe you need to set it as default for this file type:
Open Control Panel > Programs > Default Programs > Set your default programs > Select Windows Media Player from the lists under Programs > Set this program as default > OK

Window Updates for Windows Media Player

How can I determine what version of Windows Media I currently have on my Intel Core Mac? I am having trouble using Media Player since it keeps giving me the message that the player cannot play the file because it is either corrupt or the player does not support it. It is an asx file and, according to the 'help' information, this version does accept asx files. I was just wondering if I need to upgrade in order to have some success. Thanks in advance.

Is there a greater chance I will be able to play the sport's radio stations if I download the free version of Flip4Mac WMV to run on Quicktime Player or Safari Web Browser? I like listing to our local minor league team when they are on the road and I can't seem to get them on my new iMac. Thanks....

Safari and Windows Media Plug-in

CBC Radio Victoria Streaming Windows Media:

I have the latest versions of Windows Media Player 9 and Safari.

I also get that error message from time to time.
From what I understand, Windows media has some kind
of proprietary licensing system that grants the WM
Player permission to only play certain licensed
files. Unfortunately, Windows Media Player 9 for Mac
OS X only supports version 1 licenses. This means
that, as mac users, we are only allowed to play some
protected files, but not others.

Unable Windows Identity Foundation in Windows 10 TP

Hi all,
This question has been asked before but I've yet to see anyone describe the exact steps they have attempted to resolve the issue.
Microsoft Dynamics AX 2012 R2 client has a dependency upon Windows Identify Foundation being installed / option enabled.
WIF is not able to be installed on Windows 10 TP as an executable, the same as Windows 8. However, the option to manually register the DLL using the
gacutil option is not working either.
I have also attempted to resolve by running the same PowerShell command line that the AX installer uses to configure WIF.

You probably have not seen anyone reporting the exact same problem as you. All three crash reports have the same crash signature and as currently ranked 67 it is not the commonest of reasons for a crash.
I hope you enter your email contact information when reporting crashes. I note you see this crash when using videos, others may possibly see this crash in other circumstances.
You have already tried the obvious, attempts at a fix so it is now down to wait and see, maybe developers working on the bug will report something or fix it.
Did you try my suggestion of installing portable ESR ?

Windows media player extension is installed but does not pass the plugin test...what do I do now?

I followed the instructions to install the Microsoft Media Player Extension in order to be able to listen to the radio in the Youtube Toolbar. I checked to make sure it was installed as per the instructions, then I tried the test that is provided in this link: http://plugindoc.mozdev.org/testpages/wmp11.html, but the screen was just black, and the radio still doesn't work...what should I do now?

OK...but I still can't get the radio to work...I get an error message that says:
"None of the Radio Player's stations or podcasts work.
If none of the stations or podcasts work, then check whether your computer meets all the requirements below:
- Operating system: Microsoft Windows 2000/XP/Vista or Mac OS.
- Windows requirements:
- JavaScript is enabled in your browser .
- Cookies are enabled in your browser .
- Windows Media Player version 9 or higher is installed
- If you have an older Firefox toolbar version, you may need to install Media Player ActiveX .
If you have met all the requirements above and the Radio Player still doesn’t work, please contact our Support Center . ''
I've done all of the above, all requirements are met, and it STILL doesn't work!! Now what please?
Last thing says "please contact our Support Center"...isn't this the support center...if not, please let me know who I should write to?

Windows Media Player keeping Automatic Maintenance window/Windows Updates from doing auto-restart

I have a system that is connected to a domain, and it runs a video playlist in Windows Media Player for digital signage upon bootup (and auto-login). WMP is set to loop the videos over and over again, but it also is preventing automatic updates from
installing and/or auto-restarting at 3:00AM in the morning (and yes, the system power management is set to keep the computer on all the time).
How can I fix this?
I have a GPO set up to install updates and restart automatically (option 4). I tried the GPO option to use the Windows 8 maintenance window to install updates, and also tried turning that option off and just using a 3:00AM restart period. Neither
option seems to work, so it looks like Windows Media Player is preventing an auto-restart to finish the update installation. Is there any way around this, so that Windows Media Player doesn't stop Windows Updates from doing its job? I don't care
if that means the video stops playing because it just starts up again on the next bootup.
I looked at the WMP GPO's and the only option that sounds like it's related is the option to turn on or off the auto-updating of media info for WMP, but it has nothing to do with what I'm trying to accomplish. If I missed something, let me know.
If there is some other way to accomplish this, such as associating and launching the playlist file with the Xbox Videos app, I would be fine with that, but I need it to loop the playlist continually (I also use the Shuffle option
in WMP - ***see note below for another question). I still want the system to automatically install updates and reboot on a regular schedule despite the video playing in the foreground.
***Side question: is there any way to turn Repeat and Shuffle options on in WMP without having to load the GUI (for scripting a playlist)?
Just FYI: this system is actually using Windows Embedded 8.1 Industry Enterprise (from a MAPS account), but it isn't customized aside from not having the standard WinRT apps from a stock Win 8.1 install loaded - it is a stock install from the ISO.
From what I understand, it is the same as Windows 8.1 Enterprise, except that it is only licensed to be used as an "appliance" machine for a single role - which it is. So I'm assuming that there are no actual differences from a "regular"
Windows 8.1 SKU that would cause this issue. If I am completely mistaken about this, please notify me on it. The reason I'm making this statement is in case there are any differences in Embedded 8.1 Industry Enterprise that I am not aware of.
Otherwise, I welcome any assistance that would target a "regular" version of 8.1 Enterprise. NOTE: Someone said to post this into the Windows Embedded forum, but the only one that exists is the one for POSready - and this is HARDLY the
POSready version of Windows Embedded that I'm using.

Hi,
Did you use the policy Local Computer Policy\Administrative Templates\Windows Components\Windows Update\Always automatically restart at the scheduled time?
I noticed an description "restart with logged on users for scheduled automatic updates installations" policy is enabled, then this policy has no effect." it means if system installed some updates which unneeds restart computer, this policy would has no effect.
In my opinion, your problem should not caused by WMP setting. please check your installed updates whether they need restart computer.
In addition, Power Managment in Control Panel also can prevent the schedule task running.
Control Panel\System and Security\Power Options\Edit Plan Settings\Change advanced power settings\Sleep\Allow wake timers
Please make sure this option is enable.

.mp4 video, won't play in QT, Real, Windows Media, but DOES in VLC

I have a .mp4 video which plays fine (video, audio) in VLC, but does NOT play in QuickTime, RealPlayer or Windows Media Player.
I have the latest Flip4Mac plug-in installed, as well.
Is there a way to convert this into a video that will play in QT Player?
(I also tried iSquint - doesn't work there either)

Some of those are unfamiliar to me, but presumably you have them for a reason. Given that not all mpeg4 files are playable in Quicktime for the reasons stated, try moving some of those plug-ins to the desktop to see if it helps. My own 'portfolio' is as follows:
These are the downloads and the settings you need in order to view/hear pretty much everything that the net can throw at you: The setup described below has proved repeatedly successful on both PPC and Intel macs, but nothing in life carries a guarantee!
It is known to work in the great majority of cases with Safari 3.0.4, 3.1, 3.1.2, QT 7.3, 7.4.x and 7.5 and OS 10.4.11, and should also work with 10.5.4.
Download and install (or re-install even if you already had them) the latest versions, suitable for your flavor of Mac, of:
RealPlayer 11 (which is no longer in beta) for Mac from:
http://www.versiontracker.com/dyn/moreinfo/macosx/15540
Flip4Mac WMV Player from http://www.microsoft.com/windows/windowsmedia/player/wmcomponents.mspx (Windows Media Player for the Mac is no longer supported, even by Microsoft)
Perian from http://perian.org/
You should read this support page http://perian.org/#support in case you need to delete older codecs.
The latest version of Adobe FlashPlayer can be obtained from here:
http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash
(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.
Note that Adobe requires you to uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):
http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157
and also that you follow the instructions closely, such as closing ALL applications first.
Some users have mentioned that the latest Flash Player versions (v.9.0.115.0 and 9.0.124.0) in some cases conflict with Leopard 10.5.4, and that they have needed to revert to v. 9.0.47. This can be downloaded from here:
http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14266&sliceId=1
You should also ensure that you have downloaded and installed all the correct versions for your Mac of Security Updates up to and including 2008-005. (N.B. Security Updates require both a restart and a permission repair.)
In Macintosh HD/Library/Quicktime/ delete any files relating to DivX (Perian already has them). However it should be noted that Perian is not an internet plugin and will not play DivX files imbedded on a website. For that you will need the DivX Player browser plugin available from http://www.divx.com/divx/mac/
Now go to Safari Preferences/Security, and tick the boxes under Web Content (all 4 of them) to enable Java.
Lastly open Audio Midi Setup (which you will find in the Utilities Folder of your Applications Folder) and click on Audio Devices. Make sure that both Audio Input and Audio Output, under Format, are set to 44100 Hz, and that you have selected 'Built in Audio'.
Important: Now repair permissions and restart.
You should also consider having the free VLC Player from http://www.videolan.org/ in your armory, as this plays almost anything that DVD Player might not.
There is an additional 'fix' you could try if you are having problems with Flash and Quicktime, depending on which type of Mac you have:
On Intel Macs, make sure that you are not running Safari in Rosetta. You can check this, and change it, in the Get Info window.
On PPC Macs, go to the Hard Disk/Library/Internet Plug-Ins folder, and drag the file 'QuickTime Plugin.webplugin' to the desktop. Quit and restart Safari. If things have improved you can trash that file. If they haven't put it back, as the lack of this plug-in can cause QT content in some widgets to cease functioning.
And now there is an additional kid on the block: SilverLight. Microsoft has created their own version of what a replacement for Flash should be. You can read more about it here:
http://silverlight.net/
So, if you go to any sites that have been designed for this new Silverlight stuff, you can download the plug-in from here (but make certain that you are downloading SilverLight v.1.0 for OS X (10.4.8 upwards) if you are using a PPC Mac. Version 2 only works with Intel Macs:
http://silverlight.net/GetStarted/
Recommendation: Close all applications before installing any of the above, repair permissions, reboot, and repair permissions again.

Windows Media Centre - Windows Media Foundation - Windows Apps. Replacement for WMC

Still looking for a PVR replacement but DVBLogic looks like it might do the job.
Have gone down the Plex Windows App route (The clostest replacement to WMC player so far) but they are saying they are hamstrung by limitations of the App sandbox? and Windows Media Foundation.
I need some concrete information from the Windows Media Centre People or Windows Media Foundation people so that developers can be steered in the right direction to help people like me switch over from WMC to something else without major headaches, frustrations,
days and days of conversion and metadata reentry.
My post from Microsoft Community
Hi,
Since Windows Media Centre almost didn't make it into Windows 8 I have been looking to move to something else before it disappears for good.
While it might just make it into Windows 10 there certainly won't be any future development.
I not a big fan of Microsoft products but WMC is one application they nailed
Some additional smart recording options
i.e. I had to add "The Big Bang Theory - Return", "The Big Bang Theory - New", "The Big Bang Theory - Finale" etc to my series recording
A proper library manager (Plex does a great job of this) e.g. by series, season, episode - Movies - Documentaries etc with additional data downloaded.
A few more playable formats/containers
It would be perfect.
A proper Library wasn't as important as most of the metadata could be viewed directly in windows explorer.
Not supported with other containers.
This brings me to the first obstacle.
All the alternatives I have looked at so far can't or won't support .wtv files
Converting the files to another format/container loses all the explorer properties. (And some of the metadata completely)
Discussions I have had so far are pointing the finger at the "Windows Media Foundation"
I.e. Developers can't do anything with .wtv files because WMF doesn't support them.
So the question is: If Windows Media Centre is no longer viable for Microsoft why haven't they atleast provided the tools for developers to support the format/container they forced upon so many users of their product.
i.e. Metadata reader/writer
Codec/Container? player?
I need a replacement for Windows Media Centre: What is/are the alternative(s)?
