Free mp3 encoders software for linux

This module enables to listen to mp3-streams according to certain security policies (enabled user). The mp3s do not have to be in the web-servers document root.
Main features:
- XHTML compliant.
- Admin interface allows you to change position, visibility and title of the stream playlist Box.
- You dont have to fiddle around with config files. Interface is provided to configure the paths etc., user access and reset the access counter.
- Dynamic directory parsing for mp3-files
- mp3-file names are not held in a database as the File/Directory names are used to create the displayed Songs, album titles etc. as mp3 tags extraction capabilities are not included in php by default.
- Artist, Album, mp3-file browsable
- Playlist handling capabilities with playlist editor
- Demo mode for guests possible, e.g. streaming not enabled.
- Clicking on a Song will send a mpeg-url type information to the mp3-player application such as winamp or xmms. (Tested under linux with xmms only).
Version restrictions:
- The software only searches through 2 Directory structures. It is meant to go through: $mp3dir/Artist-Name/Album-Name/mp3-files.mp3 It however detects files in the Artist-Directory and shows these accordingly. As I didnt use this function, I dont know what it looks like though.

Versatile Encoder allows you to encode your own videos into good quality mpeg4 or h264. The input can be a sequence of files (as generated by blender), a file (if you want to recompress something) or a DVD/VCD (if you need to backup some movie).

This piece of software tries to guess good defaults and to help the user in his choices. It works at least under Windows and Linux, the coding platform is Linux.

It should work without a hassle under all BSD variants and probably under MacOSX too, report me if you get it working somewhere else.

MP3::Podcast is a Perl extension for podcasting directories full of MP3 files.

SYNOPSIS

use MP3::Podcast;
my $dirbase = shift;
my $urlbase = shift;
my $dir = shift;
my $pod = MP3::Podcast->new($dirbase,$urlbase);
my $rss = $pod->podcast( $dir, "This is a test" );
print $rss->as_string;

ABSTRACT

Create podcast easily from directories, using MP3s own info.

Creates a podcast, basically a RSS feed for a directory full of MP3 files. Takes information from the MP3 files themselves; it needs MP3 files with their ID tags completed.

The bundle includes two programs in the C< examples > dir: C< gen-podcast.pl >, used this way:

bash% ./gen-podcast.pl < dirbase > < urlbase > < dir to scan > that generates a static RSS from a dir, and C< podcast.cgi >, to use from a webserver. To use it, copy podcast.cgi and podcast.conf to a cgi-serviceable dir; edit podcast.conf to your liking and copy it to the directory you want. Copy also .podcast to the directory you want served as a podcast (this is done mainly to avoid dir-creeping), and also drop edit also the path to fetch the MP3::Podcast lib, and call it with C< http://my.host.com/cgi-bin/podcast.cgi/< dirname >.rss

The name of the directory to scan will be taken from the URI.

Dynamic MP3 Lister was a project I started a long time ago to create dynamic lists of MP3s quickly and easily.

Features MP3 Information extraction for things like bitrate, channels, playtime and more.

Please note that this script is discontinued, and is only shown here now as an example of my work.

MP3::Find is a Perl module to search and sort MP3 files based on their ID3 tags.

SYNOPSIS

# select with backend you want
use MP3::Find qw(Filesystem);

print "$_n" foreach find_mp3s(
dir => /home/peter/cds,
query => {
artist => ilyaimy,
title => deep in the am,
},
ignore_case => 1,
exact_match => 1,
sort => [qw(year album tracknum)],
printf => %2n. %a - %t (%b: %y),
);

This module allows you to search for MP3 files by their ID3 tags. You can ask for the results to be sorted by one or more of those tags, and return either the list of filenames (the deault), a printf-style formatted string for each file using its ID3 tags, or the actual Perl data structure representing the results.

There are currently two backends to this module: MP3::Find::Filesystem and MP3::Find::DB. You choose which one you want by passing its name as the argument to you use statement; MP3::Find will look for a MP3::Find::$BACKEND module. If no backend name is given, it will default to using MP3::Find::Filesystem.
Note: Im still working out some kinks in the DB backend, so it is currently not as stable as the Filesystem backend.

Note the second: This whole project is still in the alpha stage, so I can make no guarentees that there wont be significant interface changes in the next few versions or so. Also, comments about what about the API rocks (or sucks!) are appreciated.

MP3::Find::Base is a base class for MP3::Find backends.

SYNOPSIS

package MyFinder;
use base MP3::Find::Base;

sub search {
my $self = shift;
my ($query, $dirs, $sort, $options) = @_;

# do something to find and sort the mp3s...
my @results = do_something(...);

return @results;
}

package main;
my $finder = MyFinder->new;

# see MP3::Find for details about %options
print "$_n" foreach $finder->find_mp3s(%options);

This is the base class for the classes that actually do the searching and sorting for MP3::Find.

&MP3FS is A read-only FUSE filesystem which transcodes audio formats (currently FLAC) to MP3 on the fly when opened and read. This was written to enable me to use my FLAC collection with software and/or hardware which only understands MP3. e.g. gmediaserver to a netgear MP101 mp3 player.
MP3FS is also a novel alternative to traditional mp3 encoder applications. Just use your favorite file browser to select the files you want encoded and copy them somewhere!
How it Works:
When a file is opened, the decoder and encoder are initialised and the file metadata is read. At this time the final filesize can be determined as we only support constant bitrate mp3s.
ID3v2 tags are created from the vorbis comments in the flac file. They are located at the start of the file. As such, an application scanning a directory to read tags should not cause too much of a performance hit as the actual encoder does not need to be invoked (depending on how much data the read asks for).
A special exception to this is when an application tries to read the very last block first. Many applications do this to look for an id3v1 tag (stored in the last 128 bytes of the file). When this is detected, the filesystem simply return zeros (I dont support id3v1 tags). This dramatically speeds up applications, however it could potentially lead to corrupt mp3 files if the zeros are still in kernel cache when the application comes back to read the actual audio sequentially. In my experimentation this has not happened, I always get another read for the final block.
As the file is read, it is transcoded into an internal per-file buffer. This buffer continues to grow while the file is being read until the whole file is transcoded in memory. The memory is freed only when the file is closed. This simplifies the implementation.
Seeking within a file will cause the file to be transcoded up to the seek point (if not already done). This is not usually a problem since most programs will read a file from start to finish. Future enhancements may provide true random seeking.
For build instructions see INSTALL
Usage:
mount your filesystem like this: (you will probably have to be root)
mp3fs musicdir bitrate mountpoint [-o fuse_options]
e.g.:
mp3fs /mnt/music 256 /mnt/mp3 -o allow_other,ro
