Figure 10-3ffmpeg exported this text file containing name-value pairs representing the metadata of an MP3 file

Import Metadata

Let us imagine that I modified the metadata in the text file (from the previous section) using a text editor. Now, I want the updated metadata to be imported back into the audio file. How can I do it?ffmpeg -y
-i Kerala-Uthralikavu-Pooram-festival-fireworks.mp3
-i mp3-meta-modified.txt
-codec copy
-map_metadata 1
Kerala-Uthralikavu-Pooram.mp3

Here, -map_metadata 1 refers to the second input file, that is, the modified metadata file. (-map_metadata 0 would have simply copied the metadata from the first input file, that is, the MP3 file. We did not want that.)
