Types ¶
type GenericTag ¶
type GenericTag interface {
Title() string
Artist() string
Album() string
Comment() string
Genre() string
Year() time.Time
Track() uint32
Disc() uint32
// CustomFrames returns non-standard, user-defined frames as a map from
// descriptions (e.g. "PERFORMER", "MusicBrainz Album Id", etc.) to
// values.
CustomFrames() map[string]string
// TagSize returns the total size of the tag's header and frames,
// i.e. the position at which audio data starts.
TagSize() uint32
}
GenericTag is implemented by all the tag types in this project. It gives an incomplete view of the information in each tag type, but is good enough for most purposes.
func Decode ¶
func Decode(r io.ReaderAt, size int64) (GenericTag, error)
Decode reads r and determines which tag format the data is in, if any, and calls the decoding function for that format. size indicates the total number of bytes accessible through r.
Example ¶
f, err := os.Open("testdata/BeatThee.mp3")
if err != nil {
panic(err)
}
fi, err := f.Stat()
if err != nil {
panic(err)
}
tag, err := Decode(f, fi.Size())
if err != nil {
panic(err)
}
fmt.Println("Title:", strings.TrimSpace(tag.Title()))
fmt.Println("Artist:", strings.TrimSpace(tag.Artist()))
fmt.Println("Album:", strings.TrimSpace(tag.Album()))
fmt.Println("Track:", tag.Track())
Output: Title: Beat Thee Artist: Alexander Nakarada Album: Complete Discography (CC BY Attribution 4.0) Track: 189
