This is a rebuilt PC after a hard drive died, Windows 10 Pro N version 22H2. and YE

I am trying to access video content on cbc.ca or Amazon.ca and receive an error message that "no compatible source was found for this media" - Amazon or on cbc.ca "Oops...None of the given sources can be played".

Prior to updating Firefox to version 123.0.1, both played video on these sites without an issue.

I have uninstalled and reinstalled FF and the issue persists. I can play the video from these sites with Chrome or Edge without a problem.

I have installed Java and have tried all of the help tips without success:

I have followed and installed recommendations from : https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows however the latest Media Feature Pack for windows is from 2019 and is no longer applicable to the 22H2 version. https://www.microsoft.com/en-us/software-download/mediafeaturepack. Windows store does not offer the pack.

The changes suggested by https://support.mozilla.org/en-US/kb/block-autoplay have been applied and no change

I am not running malware bytes or a VPN.

I have cleared my cache, and browsing history, rebooted = no change.

I have no add-ons, extensions or themes installed.

I prefer to use FF, but require that I can view videos from many sites.

Hi jscher2000, That helped point me in the right direction. Many thanks! However I learned through the process of trying to add in the Media Feature pack that:

1) In order to access the "Optional Feature" settings, you have to be logged on as either a local or domain admin. (That was quite a bit of reading on multiple pages before I found this)

2) The instructions from MS are not correct. Here is their stated path to add a feature:

On Windows 10 N: Select Start, then select Settings > Apps > Apps and Features > Optional features > Add a feature. Find the Media Feature Pack in the list of available optional features.

The correct path is On Windows 10 N: Select Start, then select Settings > System > Optional Features.

Once you have those two correct, you can install the Medea Feature pack. Once installed, reboot, and log on as your account it works for everyone. I've documented this issue for my work:

In order to resolve this you have to install the Media Feature pack from Microsoft.

  1. Log onto the computer as the admin
   2. Select Start, then select Settings > System > Optional Features > Add a feature.
   3. Search for the Media Feature Pack in the list of available optional features
   4. Install the Media Feature Pack
   5. Reboot


Again thanks for the point in the right direction.

The Media Feature Pack is needed for MP4 and other MPEG-encoded media. Here is an updated Microsoft link:

Can you find the right download there? If it works, we should update the support article.

Wow, that seems like a lot of extra work, but thank you for reporting back. So if I understand correctly, there's no need to go to the download page, Windows should do the download for you?

The "download" page is only a page that takes you to "how to get it" page. That page doesn't provide the current/updated means to get to the right settings point, nor does it mention that you have to be logged on as an admin account. As well, it doesn't have any link providing the download.

The instructions I put in the first response are exactly how you need to resolve the issue. It's fairly simple, but until you jump through the hoops to locate all of the information and piece the piecemeal of information together it is a mess to find.

Following the instructions I dropped is the simplest way to get it done. Nothing more, nothing less. Just those 5 easy steps.

I didn't have to add any other add-ons after the reboot. Tested on both sites. :)

I'm having the problem right now on a new install on a current Linux OS (Sparky 7.3) on a machine with an Intel 86-64 processor, plenty of RAM and HD space. I deleted the original Firefox as Mozilla suggested and installed the "Mozilla" edition, confirmed it was the latest build, but Amazon still won't let me in. It's got me twisted up that I spent all day tweaking this OS and get to the part that should be easy, and I can't access the music stream I subscribe to. And no way am I gonna install Google or any other proprietary spyware designed so rich guys can cash in by selling me out. No plug-in or patch available to catch up to the rest of the Free World?

Do unprotected videos play on sites like YouTube, the problem is only with subscription video? That usually would be a DRM problem. See: Watch DRM content on Firefox. You may want to start a new thread for that: https://support.mozilla.org/en-US/questions/new/desktop/form

This thread is about a Windows 10 N edition user while you are using a Linux distro so you are not having the same problem as the OP.

So your issue is actually not being able to login to your Amazon account?

Also if you are having issues playing some videos or music then make sure you have packages like FFmpeg installed for the necessary codecs. Otherwise you may not be able to say view recently uploaded videos or livestream videos on Youtube for example.
