I’ve been working on automating metadata additions to my Fabric
collection using information from Discogs. I was poking around for cli
ways, especially via ffmpeg, to add the info to
a music file and chanced across a really useful gist.
A quick guide on how to read/write/modify ID3 metadata tags for audio / media files using ffmpeg.
At the bottom of the gist is a mention of ffprobe. Much more
appropriate for the task at hand, especially since it can generate
output in JSON
ffprobe gathers information from multimedia streams and prints it in human- and machine-readable fashion.
… ffprobe output is designed to be easily parsable by a textual filter, and consists of one or more sections of a form defined by the selected writer, which is specified by the print_format option.
Although to be fair, ffprobe doesn’t seem to be able to write metadata
to a file.
