theora - Jul 2009 - How to add metadata to an Ogg file?

Greetings,

If I recall correctly, there was a tool to add metadata (artist, title,
location...) to an existing Ogg file, without re-encoding it, but I
can't find it any more.

I need to add such metadata to an existing Ogg/Theora file, but without
running ffmpeg2theora again, which would be very costly in terms of CPU
resources.

Would anyone have suggestions for a way to do this?

Thank you in advance,

Cheers,

Michael.

oggz-comment (from liboggz) for any Ogg codec that uses Vorbis
comments (including Theora).
