Description
System info
ffmpeg: git master 20220910
os: ubuntu 22.04
How to reproduce:
./ffmpeg -i opus_with_title.ogg -codec copy -metadata title=somethingelse out.ogg
The output file will still have the original title.
I have attached a short sample file, but I can reproduce the issue with any ogg file containing opus audio.
Apparently this bug(?) has existed for a while, see this StackOverflow post from 2018: https://stackoverflow.com/questions/50522753/ffmpeg-add-metadata-to-oggopus-and-embed-image

I see now, thanks. For ogg files I indeed need to set metadata for the stream instead of the container. I don't know enough about file formats to say if ogg supports metadata or not.

Note:
See TracTickets
for help on using tickets.
Your command only sets the format (i.e. whole file) metadata title, but this seems to be ignored by the muxer. Instead the muxer writes per-stream metadata and that is also what the demuxer reports. To set it, you need to set stream metadata: -metadata:s title=somethingelse (see the documentation for how to set it for specific streams only). Not sure if this is a bug; probably not.
