Play MP3 files via Python's win32com support

I think the file Swing.mp3 file came with my HP printer/scanner installation, and title.wma came with my Sony multimedia XP.

To use COM in Python, you must install the Python Win32 extensions, downloaded the installer package from http://sourceforge.net/projects/pywin32/

Hi,

I have the win23com folder in my python directory.
C:\Python26\Lib\site-packages\win32com\client

I downloaded the win32com components from
http://starship.python.net/crew/mhammond/win32/Downloads.html

But somehow I am not able to play the wma or mp3 files using the above example.

I tried it with Python 2.6 and Python 2.3 (the one used in your example) both and got the same result.

Am I missing something?

I am able to play the .wav file (using Python) but not the .wma and .mp3.

I will appreciate the help.

Thanks,
Anil

You may not have any of the music files given, or worse WMPlayer.OCX is missing. On my machine a Windows XP update remove it, when MS switched the Media Player.

tune = mp.newMedia("C:/WINDOWS/system32/oobe/images/title.wma")

here is the error, use

tune = mp.newMedia("C:\WINDOWS\system32\oobe\images\title.wma")

instead.

/ is used by url
\ is used by system files.

another question, how to make a song not stop when end and keep it playing again, the repeat command, Thank for this wonderful code, it worked great with me after I made the fix. ^.^

Can you please send me the C:/Program Files/Common Files/HP/Memories Disc/2.0/audio/Swing.mp3 file, my e-mail is xdmwe@yahoo.com

Sorry, I switched to a Lexmark printer a few years ago and uninstalled the HP printer software.

You should be able to use one of the following three folder syntaxes on Windows (at least Windows XP) ...

tune = mp.newMedia("C:/WINDOWS/system32/oobe/images/title.wma")

tune = mp.newMedia("C:\\WINDOWS\\system32\\oobe\\images\\title.wma")

tune = mp.newMedia(r"C:\WINDOWS\system32\oobe\images\title.wma")

My real problem is that one of the last XP updates removed WMPlayer.OCX so I can't use this program any longer. However, modules like pygame or pyglet handle MP3 sound. Here is an example ...

# play an MP3 music file using Python module pyglet
# download pyglet free from: http://www.pyglet.org/download.html
# (no GUI window/frame is created)

import pyglet

# pick an MP3 music file you have in the working folder
# otherwise use the full file path
# (also file names are case sensitive with pyglet)
music_file = "Boing.mp3"

music = pyglet.resource.media(music_file)
music.play()

pyglet.app.run()

... and here is a pygame example ...

# play MP3 music files using Python module pygame
# pygame is free from: http://www.pygame.org
# (does not create a GUI frame in this case)

import pygame as pg

def play_music(music_file):
    """
    stream music with mixer.music module in blocking manner
    this will stream the sound from disk while playing
    """
    clock = pg.time.Clock()
    try:
        pg.mixer.music.load(music_file)
        print "Music file %s loaded!" % music_file
    except pg.error:
        print "File %s not found! (%s)" % (music_file, pg.get_error())
        return
    pg.mixer.music.play()
    while pg.mixer.music.get_busy():
        # check if playback has finished
        clock.tick(30)


# pick a MP3 music file you have in the working folder
# otherwise use the full file path
music_file = "Hot80s.mp3"

# set up the mixer
freq = 44100     # audio CD quality
bitsize = -16    # unsigned 16 bit
channels = 2     # 1 is mono, 2 is stereo
buffer = 2048    # number of samples (experiment to get right sound)
pg.mixer.init(freq, bitsize, channels, buffer)

# optional volume 0 to 1.0
pg.mixer.music.set_volume(0.8)

play_music(music_file)

I've tried the pygame example and it works fine :) But for the pyglet one I have a problem. I downloaded and installed pyglet and when I run this:

# play an MP3 music file using Python module pyglet
# download pyglet free from: http://www.pyglet.org/download.html
# (no GUI window/frame is created)
 
import pyglet
 
# pick an MP3 music file you have in the working folder
# otherwise use the full file path
music_file = "Intro.mp3"
 
music = pyglet.resource.media(music_file)
music.play()
 
pyglet.app.run()

I get the following error:

>>> 
Traceback (most recent call last):
  File "C:\Documents and Settings\jori\My Documents\Gogo\University of Glasgow\First year ( Python )\Lectures\Computing Science\CS - 1P\Python\Games and stuff\Music Player\test.py", line 11, in <module>
    music = pyglet.resource.media(music_file)
  File "C:\Python25\lib\site-packages\pyglet\resource.py", line 582, in media
    raise ResourceNotFoundException(name)
ResourceNotFoundException: Resource "Intro.mp3" was not found on the path.  Ensure that the filename has the correct captialisation.
>>>

the music file is in the working directory. Any ideas what might be going wrong?

I recall that pyglet is case sensitive to file names given, make sure you have that correct. Behaves a little bit like Unix even on a Windows machine. :)

Thanks for reminding me!
