pygame.cdrom

pygame module for audio cdrom control

pygame.cdrom.init	—	initialize the cdrom module
pygame.cdrom.quit	—	uninitialize the cdrom module
pygame.cdrom.get_init	—	true if the cdrom module is initialized
pygame.cdrom.get_count	—	number of cd drives on the system
pygame.cdrom.CD	—	class to manage a cdrom drive

The cdrom module manages the CD and DVD drives on a computer. It can also control the playback of audio cd’s. This module needs to be initialized before it can do anything. Each CD object you create represents a cdrom drive and must also be initialized individually before it can do most things.

pygame.cdrom.init()

initialize the cdrom module

init() -> None

Initialize the cdrom module. This will scan the system for all CD devices. The module must be initialized before any other functions will work. This automatically happens when you call pygame.init().

It is safe to call this function more than once.

pygame.cdrom.quit()

uninitialize the cdrom module

quit() -> None

Uninitialize the cdrom module. After you call this any existing CD objects will no longer work.

It is safe to call this function more than once.

pygame.cdrom.get_init()

true if the cdrom module is initialized

get_init() -> bool

Test if the cdrom module is initialized or not. This is different than the CD.init() since each drive must also be initialized individually.

pygame.cdrom.get_count()

number of cd drives on the system

get_count() -> count

Return the number of cd drives on the system. When you create CD objects you need to pass an integer id that must be lower than this count. The count will be 0 if there are no drives on the system.

class pygame.cdrom.CD

class to manage a cdrom drive

CD(id) -> CD

pygame.cdrom.CD.init	—	initialize a cdrom drive for use
pygame.cdrom.CD.quit	—	uninitialize a cdrom drive for use
pygame.cdrom.CD.get_init	—	true if this cd device initialized
pygame.cdrom.CD.play	—	start playing audio
pygame.cdrom.CD.stop	—	stop audio playback
pygame.cdrom.CD.pause	—	temporarily stop audio playback
pygame.cdrom.CD.resume	—	unpause audio playback
pygame.cdrom.CD.eject	—	eject or open the cdrom drive
pygame.cdrom.CD.get_id	—	the index of the cdrom drive
pygame.cdrom.CD.get_name	—	the system name of the cdrom drive
pygame.cdrom.CD.get_busy	—	true if the drive is playing audio
pygame.cdrom.CD.get_paused	—	true if the drive is paused
pygame.cdrom.CD.get_current	—	the current audio playback position
pygame.cdrom.CD.get_empty	—	False if a cdrom is in the drive
pygame.cdrom.CD.get_numtracks	—	the number of tracks on the cdrom
pygame.cdrom.CD.get_track_audio	—	true if the cdrom track has audio data
pygame.cdrom.CD.get_all	—	get all track information
pygame.cdrom.CD.get_track_start	—	start time of a cdrom track
pygame.cdrom.CD.get_track_length	—	length of a cdrom track

You can create a CD object for each cdrom on the system. Use pygame.cdrom.get_count() to determine how many drives actually exist. The id argument is an integer of the drive, starting at zero.

The CD object is not initialized, you can only call CD.get_id() and CD.get_name() on an uninitialized drive.

It is safe to create multiple CD objects for the same drive, they will all cooperate normally.

init()

initialize a cdrom drive for use

init() -> None

Initialize the cdrom drive for use. The drive must be initialized for most CD methods to work. Even if the rest of pygame has been initialized.

There may be a brief pause while the drive is initialized. Avoid CD.init() if the program should not stop for a second or two.

quit()

uninitialize a cdrom drive for use

quit() -> None

Uninitialize a drive for use. Call this when your program will not be accessing the drive for awhile.

get_init()

true if this cd device initialized

get_init() -> bool

Test if this CDROM device is initialized. This is different than the pygame.cdrom.init() since each drive must also be initialized individually.

play()

start playing audio

play(track, start=None, end=None) -> None

Playback audio from an audio cdrom in the drive. Besides the track number argument, you can also pass a starting and ending time for playback. The start and end time are in seconds, and can limit the section of an audio track played.

If you pass a start time but no end, the audio will play to the end of the track. If you pass a start time and ‘None’ for the end time, the audio will play to the end of the entire disc.

See the CD.get_numtracks() and CD.get_track_audio() to find tracks to playback.

Note, track 0 is the first track on the CD. Track numbers start at zero.

stop()

stop audio playback

stop() -> None

Stops playback of audio from the cdrom. This will also lose the current playback position. This method does nothing if the drive isn’t already playing audio.

pause()

temporarily stop audio playback

pause() -> None

Temporarily stop audio playback on the CD. The playback can be resumed at the same point with the CD.resume() method. If the CD is not playing this method does nothing.

Note, track 0 is the first track on the CD. Track numbers start at zero.

resume()

unpause audio playback

resume() -> None

Unpause a paused CD. If the CD is not paused or already playing, this method does nothing.

eject()

eject or open the cdrom drive

eject() -> None

This will open the cdrom drive and eject the cdrom. If the drive is playing or paused it will be stopped.

get_id()

the index of the cdrom drive

get_id() -> id

Returns the integer id that was used to create the CD instance. This method can work on an uninitialized CD.

get_name()

the system name of the cdrom drive

get_name() -> name

Return the string name of the drive. This is the system name used to represent the drive. It is often the drive letter or device name. This method can work on an uninitialized CD.

get_busy()

true if the drive is playing audio

get_busy() -> bool

Returns True if the drive busy playing back audio.

get_paused()

true if the drive is paused

get_paused() -> bool

Returns True if the drive is currently paused.

get_current()

the current audio playback position

get_current() -> track, seconds

Returns both the current track and time of that track. This method works when the drive is either playing or paused.

Note, track 0 is the first track on the CD. Track numbers start at zero.

get_empty()

False if a cdrom is in the drive

get_empty() -> bool

Return False if there is a cdrom currently in the drive. If the drive is empty this will return True.

get_numtracks()

the number of tracks on the cdrom

get_numtracks() -> count

Return the number of tracks on the cdrom in the drive. This will return zero of the drive is empty or has no tracks.

get_track_audio()

true if the cdrom track has audio data

get_track_audio(track) -> bool

Determine if a track on a cdrom contains audio data. You can also call CD.num_tracks() and CD.get_all() to determine more information about the cdrom.

Note, track 0 is the first track on the CD. Track numbers start at zero.

get_all()

get all track information

get_all() -> [(audio, start, end, lenth), ...]

Return a list with information for every track on the cdrom. The information consists of a tuple with four values. The audio value is True if the track contains audio data. The start, end, and length values are floating point numbers in seconds. Start and end represent absolute times on the entire disc.

get_track_start()

start time of a cdrom track

get_track_start(track) -> seconds

Return the absolute time in seconds where at start of the cdrom track.

Note, track 0 is the first track on the CD. Track numbers start at zero.

get_track_length()

length of a cdrom track

get_track_length(track) -> seconds

Return a floating point value in seconds of the length of the cdrom track.

Note, track 0 is the first track on the CD. Track numbers start at zero.
