Ogg::Vorbis::Header is an object-oriented interface to Ogg Vorbis information and comment fields.

SYNOPSIS

use Ogg::Vorbis::Header;
my $ogg = Ogg::Vorbis::Header->new("song.ogg");
while (my ($k, $v) = each %{$ogg->info}) {
print "$k: $vn";
}
foreach my $com ($ogg->comment_tags) {
print "$com: $_n" foreach $ogg->comment($com);
}
$ogg->add_comments("good", "no", "ok", "yes");
$ogg->delete_comment("ok");
$ogg->write_vorbis;

This module presents an object-oriented interface to Ogg Vorbis files which allows user to view Vorbis info and comments and to modify or add comments.

CONSTRUCTORS

new ($filename)

Partially opens an Ogg Vorbis file to ensure it exists and is actually a Vorbis stream. It then closes the filehandle. It does not fill in the objects data fields. These fields will be automatically filled the first time they are accessed using the objects instance methods. Returns undef if there is a problem opening the file or the file is not valid Ogg Vorbis.

load ([$filename])

Opens an Ogg Vorbis file, reads its information, and then closes the filehandle. Returns undef if there is a problem opening the file or the file is not valid Ogg Vorbis. This is both a constructor and an instance method. The filename is required in constructor context, but should be left out when you call this as an instance method on an object. When called as an instance method, it (re)loads the info and comment data from the file. This can be used to reset the state of the object if write_vorbis hasnt been called. Note that the path parameter is ignored in instance context.

INSTANCE METHODS

These methods may be called on actual Header objects, using the -> operator or indirect objects as you prefer.

info ([$key])

Returns a reference to a hash containing format information about the Vorbis file. Hash fields are: version, channels, rate, bitrate_upper, bitrate_nominal, bitrate_lower, and bitrate_window, length. The bitrate_window value is currently unused by the vorbis codec. You can modify the referenced hash if you want, but I wouldnt suggest it.

The optional key parameter allows you to extract a single value from the internal hash (passed by value, not reference). If the key is invalid, undef is returned.

comment_tags ()

Returns an array holding the key values of each comment field. You can then use these values to access specific fields using comment. This may seem somewhat clunky at first but it will speed up most programs. In addition, it makes it easier to support the Ogg Vorbis comment standard which allows multiple fields with the same key.

comment ($key)

Returns a list of comments given a key. If the key does not exist, returns undef.

add_comments ($key, $value, [$key, $value, ...])

Adds comments with the given keys and values. Takes an array of alternating keys and values as parameters. Keys and values should be valid ascii in the range 0x20 - 0x7D and the key should exclude 0x3D (=). This is a subset of the Vorbis standard which allows this range for the key field and all of utf8 for the value field. This will be fixed in future a release.

If an odd-length array is passed in the routine will fail and return undef. Key and value will be trimmed of characters which do not match the format requirement.

edit_comment ($key, $value, [$num])

Edits a given comment field. The optional num field is used to differentiate between two comments with the same key. If no num is supplied, the first value--as reported by comment--is modified. If the key or num are invalid, nothing is done and undef is returned. If all goes well, the old value is returned.

delete_comment ($key, [$num])

Deletes the comment given by key. The optional num value can be used to specify which comment to delete, given duplicate keys. Leaving num out will result in only the first instance being deleted. Returns undef if key or num are invalid. If all goes well, the value of the deleted comment is returned.

clear_comments ([@keys])

Deletes all of the comments which match keys in the input array or all of the comments in the stream if called with no arguments. Returns undef if any key is invalid, although all keys in the input array up until that key will be cleared. Returns true otherwise.

write_vorbis ()

Write object to its backing file. No comment modifications will be seen in the file until this operation is performed.

path ()

Returns the path/filename of the file the object represents.

cutoggvorbis is a small and fast command line Ogg/Vorbis editor. The project lets you select sections of an Ogg/Vorbis interactively or via a timetable and save them to separate files without quality loss. It uses ogg123 for playback and even works with files bigger than 2GB.
For KDE you can copy cutoggvorbis.desktop to ${KDEDIR}/share/apps/konqueror/servicemenus.
I am looking for someone to write a simple GUI for KDE or whatever!
It just needs to replace keystrokes with buttons for clicking, thats all.
Enhancements:
- An error at the beginning of the output file has been fixed, unfinished files can now be edited, and a leap in time detection while seeking has been added.
- Backward seeking is now five times faster.
- Code cleanups have been made.

MMS Decoder provides a script for sending MMS messages to a Web page.
MMS Decoder can receive MMS messages, decode them, and display them on a Web page. This is done by acting as an MMSC, which is a server to which MMS messages are sent.
The only requirement to get this to work is an internet connected webserver, with PHP support and a phone which can send MMS (some operators may have blocked all MMS servers except their own, and the application will not work with these).
When an MMS is sent, its usually sent to the operators MMSC, which notifies the reciever (by a binary encoded SMS) that she or he has an MMS to retrieve, then his or her phone connects to the MMSC server and fetches the MMS which has been made available on the server via HTTP. What my web application actually do is to pretend to be an MMSC, recieves the MMS, decodes it (its encoded as specified in the WAP-209-MMSEncapsulation-20020105-a and wap-230-wsp-20010705-a specifications) and then stores it.
The only thing you need to do to make this work on your phone, is to set the phones MMSC (may also be labeled Service Center, MMS Center, or MMS Server) to http://domain.com/mms/get.php, or something like that, and then start sending MMS messages. And best of all, it will not cost you like 20 cents which the phone operators charge, the only cost is what your operator charge for WAP access (usually a lot less than the MMS cost), since the MMS is sent over WAP.
MMS Decoder was first written as a school project, and therefore Ive written a very detailed report of the decoding mechanism. This is, how ever, written in swedish so it would not be useful to anyone who doesnt know swedish. You can grab the report here.
Enhancements:
- An installation script, which creates the database or/and the tables, was added.
- A phpMyAdmin dump of the database structure was added.
- The directory structure of the package was changed.

ABSTRACT

yEnc decoder

Convert::yEnc::Decoder decodes a yEncoded file and writes it to disk. Methods are provided for returning information about the decoded file.

JOrbis is a pure Java Ogg Vorbis decoder.
JOrbis accepts Ogg Vorbis bitstreams and decodes them to raw PCM.
Vorbis is a general purpose audio and music encoding format contemporary to MPEG-4s AAC and TwinVQ, the next generation beyond MPEG audio layer 3. Unlike the MPEG sponsored formats (and other proprietary formats such as RealAudio G2 and Windows flavor of the month), the Vorbis CODEC specification belongs to the public domain. All the technical details are published and documented, and any software entity may make full use of the format without royalty or patent concerns.
We sympathize the aim of the Ogg project. JOrbis is our contribution to the Ogg project in our style. We think the ubiquity of Vorbis decoder will leverage the popularity of Ogg Vorbis. We hope JOrbis will run on any platform, any devices and any web browsers, which support Java and every people will enjoy streamed musics without patent or royalty concerns about codec.
Main features:
- JOrbis is in pure Java.
- JOrbis will run on JDK1.0.* or higher.
- JOrbis is under LGPL.
- JOrbis includes the pure Java Ogg Vorbis player, JOrbisPlayer.
- To enjoy this player, your JVM must support Java Sound API. JOrbisPlayer is under GPL.
- JOrbisPlayer can play Ogg Vorbis live streams on UDP broadcast packets from JRoar.
- JOrbis includes very simple pure Java Ogg Vorbis comment editor, JOrbisComment.
Enhancements:
- added a property jorbis.player.playonstartup to JOrbisPlayer applet to play given stream at the start-up time. Refer to play/JOrbisPlayer.html.

OggCarton is a free, open source, home jukebox system that rips, indexes, and manages playlists for Ogg Vorbis music files.
Includes a web server for playing files on your home network. Compatible with existing MP3 files.

AudConvert is an application that is designed to take any audio format and convert it to any other audio format.
The idea for AudConvert came from my need to turn my Ogg Vorbis collection into MP3s for portable devices.
Yes, this process sometimes will result in lower quality, but sometimes it must be done.
Main features:
- Input any directory of files, get out the same directory structure (or flat directory) of newly encoded files.
- Multi-threaded: Encode up to 8 files simultaneously.
This is the first release of this software and it needs a lot of testing.
Supported Inputs:
- Ogg Vorbis (oggdec)
- MP3 (mpg123)
- FLAC (flac)
Supported Outputs:
- Ogg Vorbis (oggenc)
- MP3 (lame)
