I want to write a plugin where I need the original metadata values from the local files.
Since there is not much documentation for the API (or I don’t find it), I haven’t found a way to access the original metadata.
Based on https://picard.musicbrainz.org/docs/plugin-api/#metadata_processors I wrote already a plugin (without the need to access the original metadata) and it works fine.
For my new plugin I need to read the original metadata.
With the passed arguments (https://picard.musicbrainz.org/docs/plugin-api/#metadata_processors) I only have the new metadata, from the MusicBrainz server (as far as I know and based on my poor Python knowledge).
Pls., give me a hint.
