You do rock! :yes: 

And welcome to MSFN! :hello:

BTW, one can even let the Flash Plugin on "Always Activate", too. It works just the same!

Here's the other HTML5 tests - video site: all video types now work!

Thanks! :) I didn't expect anyone to pin this topic (I mean even the POSReady topic hasn't been), so since I've gotten used to skipping past the pinned topics to get to the new ones, I thought at first that it had been merged with another topic or moved. I looked around, still couldn't find it, and started thinking it had been deleted for some reason. :blink: Finally I saw it "hidden" above the ad that sort of breaks eye scanning, since the topmost pinned topic gets visually separated from the rest. Scared me there for a moment. :D

Indeed, but I still think it's better to turn it off while testing if HTML5 video works properly. There also seem to be some sites that won't give FF HTML5 video unless Flash is turned off.

I'll add it to the opening post.

Small note, in the EME-Free variant of Firefox should not forget set media.eme.enabled to true.

That's a good point, thanks! I guess I never thought of this because if someone went out of their way to get themselves a DRM-free version of FF, they likely wouldn't want to use this plugin either - but since it's the only way known to work with XP, it does make sense that some people might still wnat to use it as an exception. I'll add this to the instructions above.

The following is Minimum setting.

media.gmp.decoder.enabled = true

set Windows Vista compatiblemode with fcwin2k.exe in KDW or NNN4NT5.

run Firefox ... and open about:plugins and wait.

OpenH264 Video Codec and Primetime Content Decryption Module will be installed .

restore executemode with fcwin2k.exe in KDW or NNN4NT5.

If you use Windows 2000.

set environment variable MOZ_DISABLE_GMP_SANDBOX = 1

TL;DR, there is a fairly easy way to enable MP4 (H.264 + AAC) HTML5 video playback in Firefox on Windows XP using Adobe's Primetime Content Decryption Module plugin (distributed by Mozilla). Meaning, you could get rid of Flash (with some caveats). The irony of course being that you'd have to use another thing by Adobe :wacko:, but at least it's something not as prone to security problems.

Technically, this plugin has been added to FF for DRMed HTML5 video, but it can be used to play non-DRM as well. It's not officially supported on XP at this point, but hey, neither is XP itself, right? ;) I've been trying it out with FF 46 (the regular release channel version) on XP Pro SP3 x86 (with POSReady updates, though I doubt that matters any) for about a week now, and the experience has been pretty encouraging. The vast majority of HTML5 videos have worked without a hitch; ~5% have had 1-2 temporary freezes (the video stops, the audio continues with some crackle), which can be easily worked around by moving the video position slider back a bit and then forward again to where the freeze happened. I've seen only one (1) case of a show-stopper error message about "corruption or unsupported features in video" (quote not verbatim) that couldn't be worked around by jiggling the slider (not a crash, just an error message and the video stopped). You may not necessarily be as lucky, though, as the reason the plugin is not included by default by Mozilla is its reported crashing on some high profile sites.

The way to force the installation and operation of Primetime CDM in the current release version (FF 46) is to add/set the following preferences in about:config :

media.gmp-eme-adobe.forcevisible (boolean, true)

media.gmp-eme-adobe.enabled (boolean, true; this should already be the default in FF 46)

media.gmp.decoder.enabled (boolean, true; defaults to false in FF 46)

EDIT: also media.eme.enabled (boolean, true; defaults to false if you downloaded a DRM-free version of FF; thanks heinoganda for pointing this out)

After this, when you check you Plugins list, you should see a notice about the Primetime plugin getting downloaded shortly. (If you don't want to wait, click on More and then on the update link from there.) The plugin files will be placed in the gmp-eme-adobe subfolder under your FF profile.

Once it has downloadedd, set the Primetime plugin to "Always Activate", Flash to "Never Activate" (not strictly necessary, but better for testing), and go to Youtube HTML5 video player check page. Both H.264 and MSE & H.264 should have blue checkmarks. You may want to try this test page (kindly suggested by dencorso) or some Twitter videos to quickly make sure H.264 really is working (with Youtube you can get fooled by WebM getting played instead).

Based on what Mozilla devs have been saying on Bugzilla (Unhide Adobe GMP on Windows XP, Hide Adobe GMP on Windows XP in Firefox 46 and 47, Make Adobe GMP available to Windows XP users in Firefox 45 and later) it seems quite possible that this plugin could soon (FF 48+) be made available without having to use any tricks (or pre-release versions), but I suppose it's also possible that the current situation will continue indefinitely (or even that the plugin will eventually be made more difficult to access under XP). Still, why not make use of it while we can, right? :)

Thanks for checking this out on Win2K! I added a note to the opening post with a link to your instructions.

Also added a note about the media.gmp-eme-adobe.forcevisible pref getting replaced by media.gmp-eme-adobe.visible and media.gmp-eme-adobe.forceSupported in future versions.

Did some testing with 45.2.0 ESR, and everything seems to work if an additional change is made to media.gmp-manager.url. I assume this applies to other 45 ESR versions as well. See the opening post for the details.

Super job, Mixit.

I'm using Firefox on Windows XP as one of my main tools for my job, and I really needed a way to play H264 videos. It's rare to find a help topic with so many details, and so many edits to stay accurate.

Thank you very much. :)

Hello,

I have followed the steps above, however still does not work (FF 47.0.1, XP SP3). In the addons opions I can see the PCD module, however the following message appears: Primetime Content Decryption Module provided by Adobe Systems, Inc will be installed shortly, however it does not update/install. It is set to Always Activate, updates on.

I tried restarting the OS, FF, disabled firewall, same message.

The url for media.gmp-manager.url is: https://aus5.mozilla.org/update/3/GMP/%VERSION%/%BUILD_ID%/%BUILD_TARGET%/%LOCALE%/%CHANNEL%/%OS_VERSION%/%DISTRIBUTION%/%DISTRIBUTION_VERSION%/update.xml

If I try to put it in the address bar i get 400 Bad Request, tried to change the version to 47/ 47.0/ 47.0.1, same error.

How else can I get the PCD module/ other options?

If you are on XP SP3 and using FF 47.0.1, you shouldn't need to change anything in the string value of media.gmp-manager.url: it's correct already! What part of "45.x.x ESR users *ONLY*" did you fail to understand? :dubbio:
Have you considered the server may be down? Wait at least 24h, then try again. :yes:
And when you do try again, be sure to click on "check for updates" if it still has not istalled by itself.

Of course! All those variables will be undefined when using the address bar. :)

I know it's only for version 45, it did not work with the other settings so I thought I might try changing that.

Anyway, it started working after 1 day or so, the only thing I cannot see is embedded facebook videos in articles, etc (are not visible on the page, fb videos play just fine). Does not display the Play DRM content button either.

Thanks a bunch:).

Added the somewhat unfortunate news about Primetime CDM never getting official support on Windows XP to the top post.

.

@King Kadelfek: Glad I could help and I definitely appreciate you taking the time to sign up just to thank me :)

  Reveal hidden contents

There was some discussion about this in the Chrome thread, but I thought it better to create a separate topic instead of having posts buried in a different thread. The most relevant parts are here: 1 (VistaLover), 2 (dencorso), 3 (VistaLover). Since it appears to have ended on a failure, I'm taking the liberty of restating some of what was covered by them. I don't mean to overstep or hog the glory by any means, so if the mods want to prepend those posts to this thread, I have no objection.

P.S. Hi everyone and thanks for the truckloads of useful information that's been posted here in the past. I've been lurking for about 1.5 years already and thought it was about time to contribute something.

After Firefox update to 48.0.2, H264 video stopped playing in Windows XP SP3
Well, it took me two nights to find this post, Thank you very-very-very much!

In my case, Adobe DRM was installed, but somehow Decoder option was disabled.
So I just put media.gmp.decoder.enabled = true, and this helped.

You won't believe how much crazy stuff people write about this problem -
including registry tweaks, system files manual copying, dll re-registering ...
I'm happy you were here to help with just Firefox config settings!

Great thanks!
