Videos not playing on browsers

svlassis · 25 Dec 2019

SOLVED: I have Windows 10 N that do not include a needed package.
Go to settings > apps > Optional features > add a feature > Media feature pack install it, restart, wait for an update, install the update and restart and you should be good to go.

Hi there, first of all my Windows Version number is : 1909 (build 18363.535)

Some time ago I updated from windows 7 to 10.

Today I completely formatted the PC though.
I had some issues with the update (from 7 to 10) that's why I decided to format it and cleanly install windows 10.

All issues were resolved except one.

Most videos on browsers do not play!

Youtube is fine, but others are not.
For example in this post

The video does not play in Opera, Firefox or Edge without errors in dev console.

In vimeo as well, but the player there shows this error Screenshot by Lightshot

The videos in general don't have issues as I can normally watch them from another computer.

What is very strange to me is that I formatted today. Is there a general issue with windows?
Could it be something about my graphics card?

Thanks

Let's make sure that you have certain codecs available. Install the following items. NOTE: These are all free downloads via the Microsoft Store:

MPEG2 Video Extension:
https://www.microsoft.com/store/productId/9N95Q1ZZPMH4

HEVC Video Extensions from Device Manufacturer (Free):
https://www.microsoft.com/store/productId/9N4WGH0Z6VHQ

Web Media Extensions:
https://www.microsoft.com/store/productId/9N5TDP8VCMHS

AV1 Video Extension:
https://www.microsoft.com/store/productId/9MVZQVXJBQ9V

Let me know if this solves the issue.

Hi there, a detail I missed and came to understand that is crucial is that I have Windows N

The solution was to go to settings > apps > Optional features > add a feature > Media feature pack and download it.
At first it did nothing (even after a restart) but some time later, a Windows update popped up, and after installing it and restarting the videos work!

So thank you very much for your time and interest!
