|$mp3 = MP3::Info->new(FILE)||
OOP interface to the rest of the module. The same keys
available via get_mp3info and get_mp3tag are available
via the returned object (using upper case or lower case;
but note that all-caps VERSION will return the module
version, not the MP3 version).
Passing a value to one of the methods will set the value for that tag in the MP3 file, if applicable.
Tells MP3::Info to (or not) return TAG info in UTF-8.
TRUE is 1, FALSE is 0. Default is TRUE, if available.
Will only be able to turn it on if Encode is available. ID3v2 tags will be converted to UTF-8 according to the encoding specified in each tag; ID3v1 tags will be assumed Latin-1 and converted to UTF-8.
Function returns status (TRUE/FALSE). If no argument is supplied, or an unaccepted argument is supplied, function merely returns status.
This function is not exported by default, but may be exported with the :utf8 or :all export tag.
Puts WinAmp genres into @mp3_genres and %mp3_genres
(adds 68 additional genres to the default list of 80).
This is a separate function because these are non-standard
genres, but they are included because they are widely used.
You can import the data structures with one of:
|remove_mp3tag (FILE [, VERSION, BUFFER])||
Can remove ID3v1 or ID3v2 tags. VERSION should be 1 for ID3v1
(the default), 2 for ID3v2, and ALL for both.
For ID3v2, removes ID3v2 tag. Because an ID3v2 tag is at the beginning of the file, we rewrite the file after removing the tag data. The buffer for rewriting the file is 4MB. BUFFER (in bytes) ca change the buffer size.
|set_mp3tag (FILE, TITLE, ARTIST, ALBUM, YEAR, COMMENT, GENRE [, TRACKNUM])|
|set_mp3tag (FILE, $HASHREF)||
Adds/changes tag information in an MP3 audio file. Will clobber
any existing information in file.
Fields are TITLE, ARTIST, ALBUM, YEAR, COMMENT, GENRE. All fields have a 30-byte limit, except for YEAR, which has a four-byte limit, and GENRE, which is one byte in the file. The GENRE passed in the function is a case-insensitive text string representing a genre found in @mp3_genres.
Will accept either a list of values, or a hashref of the type returned by get_mp3tag.
If TRACKNUM is present (for ID3v1.1), then the COMMENT field can only be 28 bytes.
ID3v2 support may come eventually. Note that if you set a tag on a file with ID3v2, the set tag will be for ID3v1[.1] only, and if you call get_mp3tag on the file, it will show you the (unchanged) ID3v2 tags, unless you specify ID3v1.
|get_mp3tag (FILE [, VERSION, RAW_V2, APE2])||
Returns hash reference containing tag information in MP3 file. The keys
returned are the same as those supplied for set_mp3tag, except in the
case of RAW_V2 being set.
If VERSION is 1, the information is taken from the ID3v1 tag (if present). If VERSION is 2, the information is taken from the ID3v2 tag (if present). If VERSION is not supplied, or is false, the ID3v1 tag is read if present, and then, if present, the ID3v2 tag information will override any existing ID3v1 tag info.
If RAW_V2 is 1, the raw ID3v2 tag data is returned, without any manipulation of text encoding. The key name is the same as the frame ID (ID to name mappings are in the global %v2_tag_names).
If RAW_V2 is 2, the ID3v2 tag data is returned, manipulating for Unicode if necessary, etc. It also takes multiple values for a given key (such as comments) and puts them in an arrayref.
If APE is 1, an APE tag will be located before all other tags.
If the ID3v2 version is older than ID3v2.2.0 or newer than ID3v2.4.0, it will not be read.
Strings returned will be in Latin-1, unless UTF-8 is specified (use_mp3_utf8), (unless RAW_V2 is 1).
Returns hash reference containing file information for MP3 file.
This data cannot be changed. Returned data:
On error, returns nothing and sets $@.
If you find a bug, please send me a patch (see the project page in SEE ALSO). If you cannot figure out why it does not work for you, please put the MP3 file in a place where I can get it (preferably via FTP, or HTTP, or .Mac iDisk) and send me mail regarding where I can get the file, with a detailed description of the problem.
ID3v2 Support Still need to do more for reading tags, such as using Compress::Zlib to decompress compressed tags. But until I see this in use more, I wont bother. If something does not work properly with reading, follow the instructions above for troubleshooting.
ID3v2 writing is coming soon.
Get data from scalar Instead of passing a file spec or filehandle, pass the data itself. Would take some work, converting the seeks, etc. Padding bit ? Do something with padding bit. Test suite Test suite could use a bit of an overhaul and update. Patches very welcome.
o Revamp getset.t. Test all the various get_mp3tag args. o Test Unicode. o Test OOP API. o Test error handling, check more for missing files, bad MP3s, etc. Other VBR Right now, only Xing VBR is supported.
