node-red-contrib-media-id3

Node-RED node to extract and update ID3 tags of MP3 files coming in as Buffer. Based on node-id3.

Similar nodes only allow extracting/updating the ID3 tags of specified files, whereas this only allows updating MP3 files which come in as a Buffer. This makes handling easier in some situations where you don't want to save files on your local file system.

If Mode is Extract, the function takes the MP3 file in the buffer from msg.payload and extracts the ID3 tags from it and places the result back into msg.payload.

If Mode is Update, the function takes the MP3 file in the buffer from msg.payload and the tags from msg.tags and places the MP3 with updated ID3 tags back into msg.payload.
