Music file metadata editing software
I want to make a program that edits music file ID3 tags, for example: overwrites all "artist" tags for a list of files with other one.
I know some c++,python and shell scripting.
And I have some questions:
- how can I get just the metadata from a mp3 file? Mplayer shows file metadata before playback, but I could not find a switch for mplayer that displays just the data
- how can I edit the metadata?
- What libraries should I check out if I want to implement this with C++ or python?
- What about "custom" metadata tags? In the foobar2000 media player for m$ i could make my own metadata tags (like "record label"). How can these be edited & added?
Thanks in advance!
