My current ffmpeg command to do this is:
ffmpeg -i in.mp3 -i in.jpg -map 0:a -map 1:0 -id3v2_version 4 -metadata title='title' -metadata artist='artist' -metadata album='album' -metadata date='date' -metadata genre='genre' out.mp3
This is a simple webserver with one route as a wrapper around id3tag shard It uses kemal for routing
schema:
post: /edit/
image: binary
file: binary
artist: string
year: string
genre: string
title: string
album: string
port can be set by passing -p flag: idedit -p 4000
port default is 3000
It has limited error handling and will return 404 if the route params passed are incorredt
it expects all parameters to be present
params = {
'image' => image_binary,
'file' => mp3_binary,
'artist' => artist_string,
'year' => year_string,
'genre' => genre_string,
'title' => title_string,
'album' => album_string,
}response body is the binary mp3 file
Ruby query:
file = File.open('test.jpg', 'rb')
mp3_file = File.open('test.mp3', 'rb')
image = file.read
mp3 = mp3_file.read
params = {
'image' => image,
'file' => mp3,
'artist' => "artist name",
'year' => "year",
'genre' => "genre",
'title' => "song title",
'album' => "album name",
}
uri = URI('http://localhost:3000')
res = Net::HTTP.post_form(uri, params)
File.write("#{title_string}.mp3", res.body)
