User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:86.0) Gecko/20100101 Firefox/86.0
Steps to reproduce:
Windows 10 OS Version 2009 (Build 19042.867). (This is a regular version of Windows 10 and NOT an N edition)
The video on https://www.warhammer-community.com/warhammer-animation-astartes/ give a media_err_decode error due to AAC decoding issues. Same issue in Firefox Nightly.
Opera has the same issue (bug DNA-92077), but in Vivaldi (which also uses the Windows Media Foundation for proprietary codecs), things work fine. Works fine in Chrome and Chromium-based Edge too.

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.
This is because the sample rate in the file is 96K, but the maximum that Windows (supposedly) supports in their decoder is 48k[0]. Since we rely on the Windows decoder on Windows (we can't ship an AAC decoder due to license concerns) we limit the rates used. However, I notice if we remove our limiting code, that the file does work. So it's possible microsoft's decoder is now more flexible, but they're not documenting it.
I'm going to dupe this against one of our older trackers for the same issue, but will follow up in that bug, as it look like we may be able to do more here.
