I usually tag Ogg Vorbis files with EeasyTAG 2.1.7.
Now, I want to produce Ogg Opus files, and I'm not able to write tags into the file. EasyTAG bears about Ogg file not having a vorbis or a speex stream.
Another tools, such as lltag, spits messages like "Skipping this file with unknown type."
Some advice? Thanks.
