Re: Recommended container/extension for opus for tagging compatibility
Reply #3 –
Thanks for your advice regarding opus files.
Regarding tag transfer from Vorbis comments --> MP3 tags with ffmpeg, according to a post, adding this -map_metadata 0:s:0 is necessary (although maybe the OP had a specific problem with his files, as for most audio conversion ffmpeg does the tag transfer by default).
And then, instead of this :
To do the initial opus audio extraction using a GUI capable of multiple input files, you can use gMKVExtractGUI, which requires mkvtoolnix also be installed. Yes it works on webm containers.
I actually use us a FOR statement : for %A IN (*.webm) DO ffmpeg -i "%A" -vn -acodec copy "%~nA.opus"
