Free music file extensions software for linux

Smack PubSub Extensions is a set of extensions to smack.

The extensions mainly include support for JEP-0060 aka PubSub but there are also a few utitlity classes. Please refer to the maven-generated documentation for further information.

VDR MP3/MPlayer Extensions let you play MP3s with Video Disk Recorder and provide a frontend for MPlayer so you can use a DVB card to play files in formats like AVI, ASF, QT, MOV, VIVO, FLI, and FLC.

VDR MP3 plugin adds sound playback capability to VDR by Klaus Schmidinger.

Supported audio codecs:

- libmad Supports MPEG-1/2/2.5 with layers 1/2/3.
- libsndfile Supports MS WAV/A-law/u-law; Apple/SGI AIFF/AIFC; Sun/NeXT AU/SND; Amiga IFF/8SVX/16SV and more.
- libvorbis Supports Vorbis/Ogg.

The MP3 plugin is distributed as a dual-plugin together with the MPlayer plugin. The different audio codecs require additional support libraries.

VDR MPlayer plugin adds the ability to call MPlayer from within VDR (by Klaus Schmidinger), allowing to replay all video formats supported by MPlayer over your DVB card.

Note: for most formats MPlayer has to do on-the-fly transcoding to MPEG1. This requires a decent CPU to work (>1Ghz). It may work with slower CPUs if you tune down the transcoding quality.

The MPlayer plugin is distributed as a dual-plugin together with the MP3 plugin.

Music daemon(musicd) is a music playing server that supports multiple formats through plugins and multiple playlists. Musicd supports plugins to enable playing of different audioformats. The plugin-api is quite similiar to one that the popular XMMS uses. Currently XMMS-plugins are not directly supported, but if I find the time, Ill make a meta-plugin to support them.
The first reason to make the player a server is to make it possible to use many different frontends and even at the same time. You can use a GUI if you like them, but anything it can do, can be done from commandline too.
The second reason is to make sure that the GUI or X does not crash the whole player. I have found that many software with a GUI tend to crash. With musicd the player is unaffected by this and you can start the interface again.
Main features:
- Musicd has its own simple text-based protocol for player-frontend communication.
- Support for unlimited number of playlists, songs per playlist and frontends connect at the same time
- Support for both IPv4 and IPv6. Also UNIX-sockets are supported for local connections.
- Currently supported audioformats: mp3 (ffmpeg), ogg vorbis (vorbisfile) and mods (libmikmod).
- Support for OSS and Solaris ouput.
- Musicd has been tested on x86 Linux and Solaris 9.
Enhancements:
- Calling play while already playing shouldnt cause deadlocks anymore
- Load command on a file that has too long line as the last line locked up the daemon, this shouldnt happen anymore
- Invalid id3tags shouldnt give random data anymore
- Invalid filenames shouldnt crash the player anymore

Object Extensions for PHP provides several classes that add runtime object extension and callbacks to the language. Object Extensions for PHP allows the programmer to add methods and properties to an object at runtime by dynamically extending by another object.

It also allows the creation of object property lists that allow for dynamic setting/getting of values in a fashion similar to JavaScript objects. These object property lists support basic value checking.

The Object Extensions library for PHP adds the following functionality to objects that extend the base class:

- Runtime object extension to "extend" an object by another class at runtime (to virtually inherit all public properties and methods).
- Runtime callback definitions to be able to pass function/method callbacks as variables, and subsequently execute them from other function/methods.
- Dynamic object properties class to handle runtime setting/getting of object properties, as well as ability to pass function arguments as object-based parameters rather than long list of options.

OBJECT EXTENSION:

- Base class (CExtendable) implements a _extend() function by which you may vritually extend an object by an instance of another object.
- Extended object (object passed to _extend) can reference parent object if supported by extended class.
- __get, __set and __call are all overriden to handle overriding undefined properties and methods
- Ability to reference a callback in a straightforward manner ($object->_callback()->method(args, [...]))

CALLBACK FUNCTIONALITY:

- Can create callbacks directly (through CCallback and derived classes)
- Can create method callbacks by calling _callback() method on CExtendable objects
- When combined with object extension and object properties, can provide a really easy way to execute callbacks.

OBJECT PROPERTIES:

- Base class extends ArrayIterator, all properties saved in an array
- Basic functionality to check values provided and/or set default values.
- Overrides __get, __set to get/set object properties.
- Can limit property set-tability to existing properties only, or to provided array of properties.
- Can enable read-only mode.
- Overrides __call, and in the case that the a property value with the same name as the method name exists, and is an instance of the ICallback interface, this callback is executed.

PHP COMPATIBILITY:

Object Extensions for PHP uses PHP5 functionality. It would be theoretically possible to implement similar functionality into PHP4, however, since I no longer develop in PHP4, I cannot properly test it.

Epiphany Extensions 2.26.1 / 2.27.4 is yet another excellent utility you should not miss. It is actually a collection of extensions for Epiphany, the GNOME web browser.
