pygame.mixer.music not playing

[Marian Aldenhövel]

Hi,

I am trying to make pygame play music on windows. This simple program:

import pygame,time
pygame.init()
print "Mixer settings", pygame.mixer.ge t_init()
print "Mixer channels", pygame.mixer.ge t_num_channels( )
pygame.mixer.mu sic.set_volume( 1.0)
pygame.mixer.mu sic.load('file1 .mp3)
print "Play"
pygame.mixer.mu sic.play()

while pygame.mixer.mu sic.get_busy():
print "Playing", pygame.mixer.mu sic.get_pos()
time.sleep(1)

print "Done"

seems to work. It runs the loop and prints values that look like ms into the
file. After a reasonable time corresponding to the length of "file1.mp3" the
loop is exited and the program ends.

The same thing happens for .mp3 files, .ogg files and .wav files.

Fine. The only problem is that there is no sound :-).

What am I doing wrong? pyGame example games do play sound, but I have not
found an example that uses music.

My ultimate goal is to build a MP3 jukebox that runs on Windows and Linux. I
have chosen pyGame as I am making a graphical Frontend using OpenGL. I have
also tried to look at pymad (which I could not get to work on Windows, no
C-Compiler on this machine and I could not find binaries) and audiere (no
skipping, at least in the python binding. A feature I would like to have.)

Ciao, MM

Hello Marian,
First thing out i must tell you that pygame is ok for games but the
music quality is sometimes sketchy, you must set the bit rate to get
good sound quality and there are many other pitfalls. Search the net.
You are not the first to try and build a jukebox out of pygame ;)

Py> import pygame
Py> pygame.mixer.in it()
Py> pygame.mixer.mu sic.load('c:/everyday.mp3')
Py> pygame.mixer.pl ay()
Py> pygame.mixer.mu sic.fadeout(400 0)

You have a typo in the code you posted that may be your problem.

I did find a few, yes.

Currently this is a toy project as I am learning the language, so early
success means more to me than perfect results. And, as I said, I do not really
have an alternative.

Maybe some way to remote control another player would be in order. Leave it
to software that is specialized and all. But I would want something that runs
on Windows and Linux which narrows down my options.

You are refering to the missing ' in the filename?

pygame.mixer.mu sic.load('file1 .mp3)

No, that's not the problem. I did paste working code but I then edited out the
full absolute path that I had coded into the program and introduced the error.

I also tried your sample but no difference. Must be something on my system
as it does seem to play...

Ciao, MM

I tried this exact same code (except the mp3 filename, of course) on my
machine and it worked fine. ActivePython 2.3.4 and Pygame 1.6. Could it
be a hardware problem?

Perhaps Zinf?

Re: pygame.mixer.mu sic not playing

Hello again,
Sorry you have had no success. I would suspect it is your system
setup.
Seems the code is working. I didn't think you had the typo problem,
just mentioned it because it says somewhere in the docs that if the
mixer has problems with file loading it would result in a proxy object
that supported the play and stop commands.
Please post your os name and version, Python version, Pygame version,
etc.
Some genius out there might know how to fix it.
Also you can try and look for another sound package, like maybe pyFMOD
;)
Home of FMOD http://www.fmod.org/
and the Python bindings http://sourceforge.net/projects/uncassist
the people who wrote pyFMOD (lots of stuff there)

I will. Until I find something suitable I will just build a dummy class
that has the commands I need, I can later interface that to whatever I
really use. Should I ever get to that point - as I said, this is a toy
project and they tend to die suddenly :-).

I don't think so. I can play sounds on this machine and I can also play
this very file using Windows Media Player. I suspect it's software, but
I do not know at which level the problem may lie.

I could not find anything about remote-controlling it. Did not install
it, however.

Re: pygame.mixer.mu sic not playing

Just curious what is not suitable about FMOD ?
It seems to be exactly what you are looking for.
Cross platform, free, great sound, python bindings, no compiler needed.

I have looked at it. While I do not like some of the boasting on the FMOD
site it does seem very suitable.

FMOD is cross-platform but pyFMOD is available only as Win32-Setup. Does
that mean it cannot be made to work on Linux or is it just not packaged
for it? It looks like your standard DLL-Import-File as known from other
languages and uses ctypes (had to install that first). How hard can it be
to make a version that loads a shared library with the same API on Linux?

To make pyFMOD work with the current version of FMOD I had to fix it in a
few obvious places. After doing so the new version of my micro-program
looks like this:

import time
from pyFMOD import *

res = FSOUND_Init(441 00, 32, 0)
print "FSOUND_Ini t() =", res

stream = FSOUND_Stream_O pen("file1.mp3" ,0,0,0)
print "FSOUND_Stream_ Open() =", stream

res = FSOUND_Stream_P lay(FSOUND_FREE ,stream)
print "FSOUND_Stream_ Play() =", res

while True:
print "FSOUND_Stream_ GetTime() =", FSOUND_Stream_G etTime(stream)
time.sleep(1)

And plays fine. Now I need to read up on FMODs API to find out how to
eliminate the "while True;" but that should not be a problem. This would give
me a very rich API with full control.

I am having fun! Thank you all.

Re: pygame.mixer.mu sic not playing

Very cool,
glad you got it working.
Good job getting it all installed and running so fast.
It won't be long till you have a cool media player of your own.
I have not used PyFMOD yet so can't help with it ( I thought it was
cross platform too **sigh**, at least FMOD is)
Happy hacking,

Nothing. See my other posting. It just took me some time...
