🟡 Notes on how to print mp3 tags using other tools:
mid3v2 --list-raw spec/03.\ Kaste.mp3mp3info spec/03.\ Kaste.mp3exiftool -json spec/03.\ Kaste.mp3ffprobe spec/03.\ Kaste.mp3
-
🟡 Replace all inspect with pretty_print
-
🟡 Read apev2 tags (https://mutagen-specs.readthedocs.io/en/latest/apev2/)apev2.html
-
🟡 Calculate length of mp3 file (lazily)
-
🟡❓ Should TaggedFile shortcut genre return string or the V1 genre enum?
-
🟡🔒 Security: Validate sizes (configurable): max for tag is 256MB, max for frame is 16MB
-
🟡 Add more test files

🟣 V2
- 🟢 Read header
- 🟢 Read text frames
- 🟢 Cli command to print info and frames of a file
- 🟢 Logging
- 🟡 Read all V2 tags (2.2, 2.3, 2.4)
- 🟡 Eager load most common frames, lazily load uncommon frames and frames with a lot of data
- 🟡 Validate 3 character frame ids for 2.2
- 🟡 Tag ids for 2.2 are different, so SHORTCUTS have to be different: title: TT2 artist: TP1 album: TAL year: TYE track: TRK comment: COM genre: TCO
- 🟡 Better exceptions that show at which step or which frame an error occurred
- 🟡 Strict and graceful mode: stop reading frames when there is an error, but dont raise
- 🟡 Specs for 2.2/2.3
- 🟡 Unicode
- 🟡 Unicode strings must begin with the Unicode BOM
- 🟡 Terminated strings are terminated with $00 00 if encoded as unicode
- 🟡 Any empty Unicode strings which are NULL-terminated may have the Unicode BOM followed by a Unicode NULL
- 🟡 Frames that allow different types of text encoding have a text encoding description byte directly after the frame size
- 🟡 General Frame
- 🟡 raw_flags
- 🟡 raw_content / content
- 🟡 Read common frames
- 🟡 TCON with special encoding of id3v1 genres etc
-
🟣 V1
- 🟢 Read title/artist etc
- 🟢 Read genre
- 🟡 Fast read method: only load V1 if no V2 tag exists or is incomplete?
- Always leave reader in position after V2 tag
