Re: [pygame] MOD files question
Hi Will, >The docs for pygame.mixer.music mention MOD files. What kind of MOD >files can PyGame play? Does anyone still use them? I don't think I have >even seen any since MP3 took over! >Thanks, >Will McGugan I went to great effort a few weeks ago to get fmod (a commercial sound package) to play mod files with pygame, only to be told that pygame supports mod files, as you mentioned. So I tried a few different modules with pygame, including a standard ".mod" file, an ".IT" (Impulse Tracker) file, and ".XM" (extended module?) file and, if I remember correctly, an "S3M" (ScreamTracker) file. All the mod files I've ever played are in one of those formats, so pygame's module support is pretty good. Regarding whether people still use mod files, I used them in a Windows DirectX game because they were of much higher quality than any MIDI music I've heard. But the quality will really depend on the musical score. I've found some excellent mod files on the net. There are several web sites devoted to mod files, so mods are still popular. I have heard, however, that musicians who used to write music in mod format are now changing over to composing midi music. On another note (pun!), my linux box will not play mod files properly. First I had trouble with playing OGG files, but then someone told me I had to change the SDL sound settings. That fixed the OGG playback, but all the modules I play hiss, and I have changed every SDL sound setting but have had no luck; I still get hissing playback of all mods. Any ideas?

That's true. Note that you need to use pygame.mixer.music
rather than a pygame.mixer.Sound object, though.
I just tried the following on MacOSX and it worked:
from time import sleep
from pygame import mixer
mixer.init()
music = mixer.music
music.load("bigjapan.mod")
music.play()
sleep(1)
(The mod file I used is from
http://www.df.lth.se/~fernbom/music/mods/files/bigjapan.zip).

Thanks for telling me about the mod support. I assumed that pygame didn't have
mod support because I'd heard of PySonic, which led me on the wrong track. I
have tested (with pygame's mixer) not only mods, but also more complex "mod"
formats, including IT and XM. They all work, but I've had some trouble with
playback. The worst problem is that of the music hissing. The same music plays
perfectly with SoundTracker (on my Linux box) and also perfectly on Windows. I
have experimented with the mixing speed and also the buffer size, but such
changes make no difference. You may recall that I was the one with the "sound
crackling" woes when I couldn't get Ogg files to play. Someone pointed me to
SDL environment variables, and a line like: export SDLAUDIODRIVER=dsp did the
trick: no more crackling. But I still get hiss with modules. Seems to be an OS
problem. If anyone knows more detail about setting SDL variables, please tell
me, as I'd like to get modules playing perfectly, if
possible. The other problem is that I can't set the volume of the modules very
high (100% is not very loud). Any ideas?
Cheers,
Andrew.

I have no problems on Linux but in Windows the mouse doesnät show up. (Maybe just some occasional flicker.) Is this known problem or am I doing something wrong. I'm trying to set the resolution to 800x600. Best Regards /John Before switching to Python, I was writing a Java SDL app, and encountered the same problem. I wrote code to display a custom mouse pointer, which worked in a Windows window but never in fullscreen mode. Actually, it did kind-of show, appearing once in a while right near the other cursor. So, I was getting a mix of two cursors. This was so annoying, especially since I went to the trouble of having a custom animated cursor. I checked out the docs on SDL website and found that other people had the same trouble. The author of SDL said that it's currently a bug and that it may be addressed in a future version of SDL. The problem, if I recall, is that SDL can only blit the cursor on one of the two page-flipped frames (the secondary one, never the primary). Although I'm new at Pygame, I think its graphics functionality is all SDL-based, so the effect you're getting doesn't surprise me. Maybe some Pygame guru can solve the problem, but if it's an underlying SDL problem, you're probably out of luck, as I was! Cheers, Andrew.

[pygame] music module bindings for python
Hi Greg and others,
For the last few weeks I have been trying to get MODule format music to work
with Python. I have found a fair bit of MODule playing code written in other
languages, mostly c, c++, and assembler, but no code or bindings for Python,
except PySonic. I have tried to get PySonic to work with my linux box, but I
can't get it to work. I've heard that people have got it to work for linux, but
I've had no luck. Greg wrote below:

It has a setup.py file, so you should be able to compile
it with distutils instead of invoking gcc yourself.
From the setup.py, on Unix systems it expects the
fmod distribution to be in a subdirectory called "fmod"
under the directory where the .pyx files etc are. Then
you should just be able to say
python setup.py install
At least that's the way it looks like it's mean to work.
I don't have a Linux system handy to try it on right now.
If it can't find Python.h, check whether you have a
directory called /usr/include/pythonX.Y (where X.Y
is whatever Python version you're using) containing
Python.h and the other .h files that it uses. If not,
you may have to tracl down and install the appropriate
"developer" package for Python (it will be called something
like "python-X.Y-devel"). You shouldn't have to install
the complete Python source.

I have followed the advice above, but still got hundreds of compilation or
linking errors. Sorry I'm not specific about the errors, but I don't have the
technical expertise to get the installation working. I'm almost totally new to
Python, and so I'm not up to extending and embedding with Pyrex, SWIG, etc. Has
anyone got PySonic (and hence Fmod) to work under linux?
Another MODule player I know of is called MikMod, which is Open Source, unlike
FMod. I've searched the web for Python bindings to MikMod, and almost had
success. Specifically, I searched for "mikmod binding for python". I got a
result titled "Lateral Opinion: 13.10.2004". The page's links are all dead,
but the author had the following to say:
MOD me up!
MOD files are like MIDI files, only the MOD includes it's own
instrument set, called samples, and instructions on how to repeat and
alter those samples to make a tune.
Good news: there are nice-sounding, funny MOD files that are about 30KB
in size.
Better news: There is a popular library to play them! It's called
Mikmod, and your distro has it (and it's a dependency for KDE's
multimedia packages too).
Even better news: It has support for playing simple sounds (samples in
mod lingo) by calling a couple of functions.
Awesome news: It includes a software mixer so you can just tell it to
play this, then play that, then that, and a tune in the background, and
everything sounds at the same time.
So, we have a winner. This baby can handle everything I need for the
game!
But... is that a snake in your pocket?
I can't find a Python binding for it. I am sure as soon as I post this
article someone is going to come up and tell me, here they are, moron!
But I just can't find any.
So, I decided to do something I wanted to do already and learn to use
Pyrex. Pyrex is a tool to write python extensions, with almost-free
access to C libraries, in an almost-python language (only minor syntax
differences).
That way, I could write a Python module to use Mikmod.
You know what? It was almost scarily simple 2. I didn't wrap all of
Mikmod 3 because I don't need it, but now I can do stuff for games
and apps almost trivially.
Even more: Pyrex has awesome distutils support, so building the
extensions, usually a pain in the rear, is trivial (mostly you just
copy and delete stuff, with some search and replace).
One thing I found I did nicely is this: Mikmod requires you to call
Mikmod_Update every once in a while so it fills the soundcard's buffer
with stuff to play. If you don't, it skips.
So, I just started a thread that loops and takes care of it. You don't
even have to know about it to use the extension. Oh, sure, if your
Mikmod is not threadsafe, it breaks. Well, get a decent Mikmod
package, then.
How does it look?
Here's a whole noisy proggie
#Load the modules
import mikmod, time
#Init the library
mikmod.init()
#40 voices, 20 for music, 20 for random sounds (overkill)
mikmod.setNumVoices(20,20)
#Enable sound, starts the thread that pushes sound, too
mikmod.enableOutput()
#Create a module, that is, a music track
module=mikmod.Module("BasicInstinct.mod")
#Load two samples, just a couple of noises
s1=mikmod.Sample("lost.wav")
s2=mikmod.Sample("swap.wav")
#Start playing the song
module.play()
#For the duration of the song, each second, make some noise
while module.active():
s1.play()
time.sleep(0.5)
s2.play()
time.sleep(0.5)
#Close the mikmod library, stop the thread, etc.
As you can see, the author has been successful in getting mikmod to work by
writing his own bi

Unfortunately, I still can't solve the problem. The demo code has no call to
pygame.mixer.init. Instead, the code (the Shadow of the Beast animation on the
website) looks like:
...
pygame.init()
screen = pygame.display.set_mode((640, 480))
pygame.display.set_caption("Shadow of the Beast")
s1 = pygame.image.load(os.path.join("resources", "bgd1_ciel.png"))
s2 = pygame.image.load(os.path.join("resources", "bgd2_montagnes.png"))
s3 = pygame.image.load(os.path.join("resources", "bgd3_sol1.png"))
s4 = pygame.image.load(os.path.join("resources", "bgd4_sol2.png"))
s5 = pygame.image.load(os.path.join("resources", "bgd5_sol3.png"))
s6 = pygame.image.load(os.path.join("resources", "sprite_nuages1.png"))
s7 = pygame.image.load(os.path.join("resources", "sprite_nuages2.png"))
s8 = pygame.image.load(os.path.join("resources", "sprite_nuages3.png"))
s9 = pygame.image.load(os.path.join("resources", "sprite_nuages4.png"))
s10 = pygame.image.load(os.path.join("resources", "sprite_barriere.png"))
s11 = pygame.image.load(os.path.join("resources", "fireworks.png"))
s12 = pygame.image.load(os.path.join("resources", "sprite_arbre.png"))
s13 = pygame.image.load(os.path.join("resources", "scrolltext.png"))
music = pygame.mixer.Sound(os.path.join("resources", "remix.ogg")).play()
pygame.mouse.set_visible(False)
and then the main game loop.
There is no call in the same code to pygame.mixer(), so I added one as you
suggested, and even tried it in several places, like after pygame().init, after
the screen opening, after the call to start the music, and so on, changing only
one line for each test, but had no luck. I checked out the webpage on the use
of the mixer, and found there's a pre_init() call that can be used before
pygame.init(). I even tried that, but it made no difference. I then decided to
use Synaptic Package Manager to re-apply the libsdl mixer library, in case that
was the problem. Still no luck.
By the way, as I mentioned in the original post, I'm using ubuntu Linux.
Any help would be much appreciated.
Thanks in advance,
Andrew.

[pygame] sound crackling and fmod
Hi, I'm totally new to Python and Pygame, and have started by testing out the demos on the Pygame website. I'm using Ubuntu Linux. When I ran the "Shadow of the Beast" demo from the website, the animation was great but the sound (an Ogg file) was crackly on my speakers. I decided to try out other demos from the same website, and they too crackled. Seemed like a problem with my speakers, but when I played the same Ogg file with ubuntu's Totem Movie Player, the music played perfectly. I'm wondering why. If anyone out there is using ubuntu Linux and has any ideas, please help. Secondly, I've already used the excellent sound package, Fmod, in a c++ game I made, and have tested Fmod with java successfully, but I don't know how to use it with Pygame. I thought Fmod would be the best choice (rather than the Pygame mixer that is called in the demos, which seems to cause crackling). I have downloaded the latest Fmod for Linux, and have downloaded pySonic too. Unfortunately, the pySonic binary download is for Windows only. I did some web searching, and someone said that he's heard pySonic will work under Linux, but that you have to use PyRex, and follow special build instructions. The final result should be a shared object file for linux. I downloaded the required source code from sourceforge, and tried to follow the build instructions, but my call to gcc failed and I so I couldn't complete the build properly. This is frustrating. Surely someone has pySonic in a shared object form for linux? I plan to use Python and Pygame, and also to have the power of Fmod. Can someone please help out here with regard to the two problems: 1) why am I getting the crackling when running the demos?, and 2) How to I get a copy of Fmod in shared object form (for linux)?
