Thank you. The reason I'm converting to ogg-opus is that I can send it via whatsapp.

Whatsapp is only accepting opus contained in ogg. 

I get this error in windows when converting mp3 to ogg (opus codec)

Except for the dash you forgot ( -c:a libopus) this is indeed a very basic conversion to opus.

In general converting a lossy format to another (mp3 to opus) is frowned upon.
It's recommended to convert the original lossless format (wav, flac, etc) if you still have it.
