pycdio 0.19

Python OO interface to libcdio (CD Input and Control library)

Latest Version: 0.20

# Introduction

pycdio is a Python interface to the libcdio, the [CD Input and Control library](http://www.gnu.org/software/libcdio)

You can get the source at the same place as libcdio: ftp://ftp.gnu.org:/pub/gnu/libcdio/

The pycdio and libcdio libraries encapsulate CD-ROM reading and control. Python programs wishing to be oblivious of the OS- and device-dependent properties of a CD-ROM can use this library.

# Requirements

To build on Debian (e.g. Ubuntu):

apt-get install python-dev apt-get install libcdio-dev apt-get install libiso9660-dev apt-get install swig pkg-config

# Completeness

libcdio is rather large and yet may still grow a bit.

What is in pycdio is incomplete; over time it may grow to completion depending on various factors: e.g. interest, whether others help out.

Sections of libcdio that are currently missing are the (SCSI) MMC commands, and the cdparanoia library. Of the audio controls, I put in those things that didn't require any thought. The ISO 9660 library is pretty complete, except file stat() information which is at present is pretty minimal.

That said, what's in there is very usable It contains probably more access capabilities than what most media players that don't use libcdio have.

The encapsulation by SWIG is done in two parts. The lower-level python interface is called pycdio and is generated by SWIG.

The more object-oriented module is cdio; it is a Python class that uses pycdio. Although pycdio is perfectly usable on its own, it is expected that cdio is what most people will use. As pycdio more closely models the C interface, it is conceivable (if unlikely) that diehard libcdio C users who are very familiar with that interface could prefer that.

It is probably possible to change the SWIG in such a way to combine these pieces. However there are the problems. First, I'm not that much of a SWIG expert. Second it looks as though the resulting SWIG code would be more complex. Third the separation makes translation very straight forward to understand and maintain: first get what's in C into Python as a one-to-one translation. Then we implement some nice abstraction off of that. The abstraction can be modified without having to redo the underlying translation. (But the reverse is generally not true: usually changes to the C-to-python translation, pycdio, do result in small, but obvious and straightforward changes to the abstraction layer cdio.)

There is much to be done - you want to help out, please do so!

Standalone documentation is missing although many of the methods, classes and functions have some document strings. See also the programs in the example directory.
