Pygame – Access CDROM
”;
The pygame library has pygame.cdrom module that enables the program to manage playback from audio CDs and DVDs. We need to explicitly initialize this module for its use.
>>> import pygame >>> pygame.cdrom.init()
The module defines all important CD class to represent the CDROM device. The constructor requires ID of CDROM drive available, starting with 0.
>>> obj=pygame.cdrom.CD(0)
The CDROM object has access to following useful functions to control the playback.
| init() | initialize a cdrom drive for use |
| quit() | uninitialize a cdrom drive for use |
| play() | start playing audio |
| stop() | stop audio playback |
| pause() | temporarily stop audio playback |
| resume() | unpause audio playback |
| eject() | eject or open the cdrom drive |
| get_busy() | true if the drive is playing audio |
| get_paused() | true if the drive is paused |
| get_empty() | False if a cdrom is in the drive |
| get_numtracks() | the number of tracks on the cdrom |
| get_track_audio() | true if the cdrom track has audio data |
| get_track_start() | start time of a cdrom track |
| get_track_length() | length of a cdrom track |
First, initialize the object.
>>> obj.init()
To find out how many tracks are present in the current CD −
>>> obj.get_numtracks() 8
To start playing the required track, give its number to play() function.
>>> obj.play(4)
To pause, resume and stop the playback, we can use relevant functions listed above.
