EXTERNAL SPECIAL-VARIABLE

ID3V2-TYPE-MAP

Source

A map of id3v2 frame type name to human-readable names.
See http://id3.org/d3v2.3.0

EXTERNAL CLASS

FILE

Source

Container class for a file.

Manages all the decoding information so that it is easily accessible.
Also takes care of managing the underlying C values so that you don't
have to worry about garbage collection or buffer allocation and so forth.
It also takes care of setting up the desired decoding parameters and flags.

The slots of the file are not settable, however you can reconfigure the
file at any point using REINITIALIZE-INSTANCE. Note that this will have
to DISCONNECT the file and delete its handle first. It will reCONNECT
if it was previously connected, but you cannot do this if you are in the
middle of processing data or need to otherwise preserve state.

You can find more information about most of the properties that can be set
via initargs in the mpg123.h mpg123_params and mpg123_param_flags enums.

EXTERNAL CLASS

METADATA

Source

Class container for ID3 metadata.

When re/initialising this, you should pass the ID3V1/2 struct pointers as
the respective initargs. Note that ID3V1 and ID3V2 values will coexist, but
ID3V2 values should always come before ID3V1 values in the resulting fields
list. Also note that duplicate (by EQUAL) entries are not stored.

Note that when the metadata is reinitialised, all fields and pictures are
cleared out first, before potentially being repopulated by the passed args.

Note that ID3V1 text values are by default parsed by UTF-8 first and by
ISO-8859-1 if that fails. See DIRECT-STR. You can override the UTF-8 default
by specifying the :ID3V1-ENCODING initarg.
