Free ogg software for linux

Dirogg is a simple script for migrating your entire music collection from mp3 to Ogg Vorbis (ogg).
dirogg is a recursing script, which means you run it at the top directory of your music collection, and it will take care of the rest. Enjoy!
Installation:
Just copy the "dirogg" script to a directory in your path, like /usr/local/bin.
To use, enter a directory in which you want to convert all mp3 files to ogg. It will then recurse into subdirectories and convert these files to ogg as well. Note that your mp3 files will not be removed unless you set so in.
Enhancements:
- Parallelizing support was added to process multiple files simultaneously.

alogg is an Ogg/Vorbis addon library for Allegro.

alogg is a library which makes it easier to use Ogg/Vorbis streams with Allegro. It offers facilities to decode, stream, and encode Ogg/Vorbis streams, and integrates those facilities with Allegros datafile and sample loading routines.

alogg comes with a sample player, streamer, and encoder based on Allegros sound routines.

Autogg is an Ogg player that categorizes music independently of the catalog structure. Autogg started as a music player that also sorted your music and presented it in a nice list based on albums, like a jukebox. Originally it played files of the ogg vorbis format but now it has support for more formats.

Now it is sorting both mp3 and ogg files, but the playback is done by xmms, or you can use drag and drop with other players.

How to use the player (dedicated to ted)

1: click the scan button over the list to the right, select a directory wich includes .ogg files.

Tip: select / directory to get all the .ogg files in your system

2: Click on the start scan button, wait till the directory tree show up in the list.

3: Doubleclick on a track to add it to the playlist, the track will then be played when its time

Transcogg software is an Amarok script to shrink your files (MP3 or OGG) before copying them to your devices.

It reduces the quality of the tracks copied to the devices ( oggenc -q 0 )

You need a device that supports Ogg/Vorbis to benefit of this script.

You have to ask Amarok to convert file "if possible" if you want the OGG files to be reduced.

Ogg Vorbis is a fully open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel.

This places Vorbis in the same competitive class as audio representations such as MPEG-4 (AAC), and similar to, but higher performance than MPEG-1/2 audio layer 3, MPEG-4 audio (TwinVQ), WMA and PAC.

Vorbis is the first of a planned family of Ogg multimedia coding formats being developed as part of Xiph.orgs Ogg multimedia project.

libVorbis is the core Ogg stream / Vorbis engine.

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.

ogg2mp3 takes a list of OGG Vorbis formatted files and converts them to mp3 format. ogg2mp3 project is useful when you want to transfer OGG encoded files to a device which doesnt support the format (e.g. an iPod).

Each file specified on the command line is converted to a file with the same name except the ``.ogg at the end is replaced with ``.mp3. The new file is created in the current working directory unless otherwise specified with the --output-directory option.

By default, ogg2mp3 prints one line of output per file processed (printing it as the processing of that file starts) as follows:

processing 1 / 10 : 01_big_exit.ogg -> ./01_big_exit.mp3

Where 01_big_exit.ogg is the first of ten files to be processed (1 / 10), and the output file is called ./01_big_exit.mp3.

This behaviour can be modified using the --quiet and --verbose options.

OPTIONS:

Note that all command line options may be abbreviated to the shortest unique version, e.g. --output-directory can be shortened to -o because there are no other options beginning with -o. However, to see the version, at least --vers is required since there is also the --verbose option, thus ``vers is the shortest unique abbreviation of ``version.

--debug n

Set the debugging level to n. Ranges from 0 to 10, 10 being really verbose, 0 being just warnings (the default).

--id3-tags or --noid3-tags

Specify that you want (or not) ID3 tags to be copied into the MP3 file.

--force-overwrite

If an output .mp3 file already exists, overewrite it without prompting (the default is to skip such files and issue a warning).

--help

Show a brief command line help message and exit.

--output-directory dir

Tell ogg2mp3 to create the .mp3 files in the directorry dir instead of the current directory.

--prefix prefix

Prefix all output filenames with prefix.

--quiet

Dont print output unless there is an error.

--suffix suffix

Append suffix to all output filenames just before the .mp3 extension.

--verbose

If --quiet is not spcified, this switch increases the amount of information displayed as each file is processed. The extra information details the ID3 tags found in the source file.

--version

Print the program name and version and exit.

EXAMPLES:

Example 1

$ ogg2mp3 echo.ogg got_two_legs.ogg pripple_ipple.ogg
processing 1 / 3 : echo.ogg -> ./echo.mp3
processing 2 / 3 : got_two_legs.ogg -> ./got_two_legs.mp3
processing 3 / 3 : pripple_ipple.ogg -> ./pripple_ipple.mp3
This command will create three new files: echo.mp3, got_two_legs.mp3, and pripple_ipple.mp3 in mp3 format in the current directory.

Example 2

$ ogg2mp3 -o /media/ipod my_song.ogg
processing 1 / 1 : my_song.ogg -> /media/ipod/my_song.mp3
This command creates the file my_song.mp3 in the directory /media/ipod.

Example 3

$ ls *.ogg
track_01.ogg track_02.ogg track_03.ogg
$ ogg2mp3 -o /tmp --verbose *.ogg
processing 1 / 3 : track_01.ogg -> /tmp/track_01.mp3
ID3 Tags:
album => Frengers
artist => Mew
date => 2003
genre => Pop
title => Am I Wry? No
tracknumber => 1

processing 2 / 3 : track_02.ogg -> /tmp/track_02.mp3
ID3 Tags:
album => Frengers
artist => Mew
date => 2003
genre => Pop
title => 156
tracknumber => 2

processing 3 / 3 : track_03.ogg -> /tmp/track_03.mp3
ID3 Tags:
album => Frengers
artist => Mew
date => 2003
genre => Pop
title => Snow Brigade
tracknumber => 3

As you can see, adding the --verbose option turns on display of ID3 tags.

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.
