func (*Tag) ReadHeader

func (t *Tag) ReadHeader(th TagHeader) error

ReadHeader reads the 10 bytes header and parses the data which gets stored in the tag header.

type TagHeader

type TagHeader [10]byte

TagHeader is the header content for an id3v2 tag

func (TagHeader) IsValidID

func (th TagHeader) IsValidID() bool

IsValidID checks that the tag header starts by the right ID

func (TagHeader) ReadFlags

func (th TagHeader) ReadFlags() Flags

ReadFlags reads the header flags

func (TagHeader) ReadSize

func (th TagHeader) ReadSize() (int, error)

ReadSize reads the size of the tag header

func (TagHeader) ReadVersion

func (th TagHeader) ReadVersion() Version

ReadVersion extracts the version information.

type Version

type Version struct {
	Major    uint8
	Revision uint8
}
