Simple ID3 Meta Data API which supports ID3 V1. More...

Inheritance diagram for MetaDataID3V1:

Public Member Functions
bool	begin ()
	(re)starts the processing

void	end ()
	Ends the processing and releases the memory.

void	setCallback (void(fn)(MetaDataType info, const char str, int len))

size_t	write (const uint8_t *data, size_t len)
	provide the (partial) data which might contain the meta data

Protected Member Functions
int	findTag (const char tag, const char str, size_t len)
	find the tag position in the string - if not found we return -1;

void	processnotifyAudioChange ()
	executes the callbacks

void	processPartialTagAtTail (const uint8_t *data, size_t len)
	We had part of the start tag at the end of the last write, now we get the full data.

void	processTagFoundPartial (const uint8_t *data, size_t len)
	We have the beginning of the metadata and need to process the remainder.

void	processTagNotFound (const uint8_t *data, size_t len)
	try to find the metatdata tag in the provided data

Protected Attributes
bool	armed = false

void(*	callback )(MetaDataType info, const char *title, int len)

ParseStatus	status = TagNotFound

ID3v1 *	tag = nullptr

ID3v1Enhanced *	tag_ext = nullptr

char	tag_str [5] = ""

int	use_bytes_of_next_write = 0
