How to install opus codec for playback on Windows 10

Question

How do I install the opus audio codec onto my Windows 10 machine? I have an mkv file with HEVC video and OPUS audio.

• When I play the file in VLC, its fine
• Windows 10 Film and TV app: there is video but no sound
• Media Player Classic: there is no sound or audio.

The official site (http://opus-codec.org/downloads/) has the actual dlls, but nothing to 'install' them to windows. I also tried installing the Web Media Extensions from the Windows store, but that does nothing. I'm running Windows 10 Pro 1709 16299.371

• What do I need to install to get sound for the Windows 10 films and tv app
• What do I need to install to get sound and video for media player classic?

Solution 1

Install Web Media Extensions from Microsoft Store. Web link: https://www.microsoft.com/en-us/p/web-media-extensions/9n5tdp8vcmhs

Videos containing opus audio will play well but for audio files, extension .opus isn't recognized therefore .mp3 would suffice.

Note: Web Media Extensions supports UWP only so apps like Groove Music and Movies and TV will work.

Solution 2

You can't install, in the package are exe files that you use in the command line.

Opus-tools provides command-line utilities to encode, inspect, and decode .opus files. Opusfile provides application developers with a high-level API for decoding and seeking in .opus files. DLLs for the required libraries libogg 1.3.2, libopus 1.1.1 and openssl, are also included in the binary package.

For the record, it looks like (though I could be misinterpreting, if Opus got supported but not MatroskaOpus,) "Media Player Classic" has supported the Opus codec since 2012. If it's not playing there, that's a bug / technical problem in MPC-HC.

for audio files, extension .opus isn't recognized therefore .mp3 would suffice - this is false as of (at least) Win10-1903. Renaming a file from .opus to .mp3 did not enable Windows Media Player to play it (even with WME installed), whereas Groove Music (the other included media player) was able to play my OGG/Opus file regardless of its extension.

@JamesTheAwesomeDude It's because Windows Media player uses internal decoders. WME (now comes pre-installed) supports UWP only.
