You have to download and install (or just enable, depending on your version of Windows) the Windows Media Feature Pack. See https://support.microsoft.com/en-us/topic/media-feature-pack-list-for-windows-n-editions-c1c6fffa-d052-8338-7a79-a4bb980a700a. Then, it should say "yes" for h.264 and aac at htps://html5test.com/.
Disabled the video decode thing and the hardware acceleration but it still doesn't work.
Make sure to reenable those.
