There should be some guides on the Github website but essentially you 
can create your own "fork" of the PyKaraoke source code via the Github 
website. Then you can download the source from your own fork and work 
with that. When you're ready, you can submit changes back to the main 
project by issuing a Pull Request.

Ken, I totally understand. I wasn't at all suggesting that you should tray Py 
for a commercial program. I was just addressing your thought that commercial 
programs didn't or couldn't do this.

Personally, I would love to even try Py, because I'm a karaoke hobbyist. 
However, I don’t know much of anything about code. I don’t know how to compile 
a Windows version of etc...:(

brilliant, even as it stands.

For example to find "Elvis Presley In The Ghetto" with PyKaraoke you can
just enter "elv pre ghe" and you have it.

But with the software I used in a local bar here, it will search on a title,

Thanks Kevin I will look into that, I find that the program is 
beautifully written, with lots of really helpful comments. it's a lesson 
to me on how Python should be done.


I do however miss my ancient Epsom dot matrix printer, i could print out 
someone's code on a yards long piece of endless paper, to really try and 
understand it.

What a wonderful idea.

My first recommendation is to see if a machine on which you had already 
installed it *and it was working* still shows it working -- automatic
updates to Windows XP itself have been known to break things.

If older installs are working, the next thing to look at is whether the
newer ones which don't are on the same Service Pack of WinXP; SP3 is the
final one, after which there were only security updates (and those are
about to stop), but lots of stuff changes from SP2 to SP3, and that could
be a problem.

If you can grab a screenshot of the error message, that would be helpful
too.

Cheers,

It's still going, just at a slower pace now that the core karaoke
playback functionality is finished and stable. You may have seen that
I released v0.7.3 this week.

This would be useful. The player threads do make callbacks when songs
are completed, though, which is something to be aware of (i.e. may
need proper IPC between the GUI thread and the player thread). Which
reminds me: someone did report an issue with a multicore CPU on
Windows, which I suspected at the time was due to the callbacks
between the Pygame player and the GUI. What you have done there sounds
like it could be useful for that.

Re: [Pykaraoke-discuss] pykaraoke windows developer

[Stephen Burke]

Thanks for the quick response Kelvin.  I'm glad to hear that pykaraoke is
still kicking.  I would definitely like to contribute back at least what we
have hacked together here.  I'm in the process of digging up the latest
source I have on my box & hopefully there will be some fixes in there that I
can pull out & make some patches.  My spare moments these days are few & far
between (I have a 5 mo old son :) but since he's started sleeping through
the night I have more time than I know what to do with :)  I have a Vista &
Win7 box and I've used pykaraoke enough that I think I could look over the
Windows port.

My wife and I worked mainly on modifying the gui so that you could play a
song while adding other songs.  When she was singing I couldn't look up
another song without her video freezing while the gui was occupied.  I think
it mainly comprised kicking off the video window in it's own thread.  Has
something like this been worked on in the past?  Commit access btw would be
great.  I'll probably throw the patch your way first anyway, but first
things first I'll find my old code & setup pykaraoke on Vista & see how it
goes.  I'll probably be taking baby steps contributing since my free time to
code is pretty small.

As for other features, I do have some other ideas written in an email
somewhere.  I'll try to find them & get back to you.

Hi Steve,

Good to hear from you.

I was reading the http://kibosh.org/blog/ and saw a couple posts about the

As yet we don't have a Windows developer: if you have any spare moments to
contribute (however small) then that would be much appreciated. I'd be happy
to give you commit access to the repository at Sourceforge.

There probably isn't a huge amount to do that is Windows-specific. I have
run it in a VM occasionally and the main thing I noticed was that a few of
the popup windows were badly sized. Also I only have XP here so it would be
good to have someone with Vista on board to cover that. I have heard, for
example, that songs cannot be cancelled part-way through playback on Vista,
but don't have a copy to try it out.

Building release installers for Windows is pretty easy these days. I
documented the procedure here:
http://kibosh.org/pykaraoke-development-windows-installer/

Once you have the prerequisites installed, it's just a couple of commands to
build the entire installer.

Any features you think are lacking would be gratefully received, and
generally these would work on any platform. If you don't have Linux over
there then I can easily run your changes here to make sure they work
cross-platform.

Do you have any thoughts on useful features to add to the roadmap? Some of
the things I'd like to add, but haven't had the time to do yet, are:

* More KJ features (singer tracking etc, splash screen between songs)
* Playback of LRC & other formats
* Progress bar

Would be interested to hear any other ideas you have.

Best regards,
Kelvin.

Re: [Pykaraoke-discuss] PyKaraoke windows bug

[David Rose]

It's a great idea to play a video behind the karaoke lyrics. 
Unfortunately, due to limitations in the pygame library that PyKaraoke 
uses to provide graphics, it's not possible to do this without a major 
low-level redesign (we'd have to customize large portions of the video 
decoding library provided by pygame).

There are similar limitations that make it difficult to provide a 
scrubber bar. :/

Cool.  Works great.  Bold move not even bothering to make a scrubber  
bar... they never work anyway :)

I might as well send a feature request while I'm here...

Playback of arbitrary videos behind the karaoke lyrics.  These two  
UI's both would work for me:

Option 1: User selects a folder in preferences.  Place a button in the  
menu to turn video on / off.  Turning video on plays random videos  
from that folder behind the karaoke video (the Stepmania DDR clone  
does this and it's awesome).

Option 2: Drag and drop of a video file onto the playback window (or  
the fullscreen display on monitor 2) starts running that video.

Re: [Pykaraoke-discuss] Pykaraoke for OSX

[Kelvin Lawson]

Hi Rob,

I've spoken with a PyKaraoke user who has got it running on OSX.

You'll need to install Python (www.python.org), Pygame, WxPython and 
Numeric. I think the latter three are available from here:
http://pythonmac.org/packages/

He didn't get the compile/install working and we haven't investigated 
why yet, but it's possible to run it without installing by just 
unpacking PyKaraoke and typing:

python pykaraoke.py

It looks pretty nice on OSX, but the config window was a strange size. 
You can fix this by changing the CONFIG_WINDOW_SIZE parameter in 
pykaraoke.py to 240,90.

Would be interested to hear how you get on.

Kelvin.

I installed PyKaraoke on a mac notebook running OSX and it actually did seem
to work properly except for it hiding the mouse even when the pointer
*wasn't* in the display window (at least, pycdg.py, the player, worked
without difficulty).

I don't recall there being any special steps to make that work, at least as
far as the player itself goes.

Have you given it a shot and encountered an error? It's meant to be
cross-platform so it *should* just work assuming you've got a working Python
environment.

Sorry for my bad english, i´m a native german speaker.


No worries :)

I'm not sure what the minimum requirements are I'm afraid. The latest 
version received some big performance improvements, but I would think 
that PyKaraoke would still struggle on a Pentium One. Suck it and see?

The latest release of PyKaraoke (i.e. the one with the optimisations) 
requires a relatively recent version of WxPython (2.5) so an old distro 
probably wouldn't fit the bill.

All the best,
Kelvin.

The compat libraries were clearly the problem.

Right, the compat- stuff represent older versions of the library.  It 
appears that with both compat-wxPythonGTK2 (the old version) and 
wxPython (the current version) installed, you end up using the old 
version for some reason, due to the way Fedora sets up the paths to the 
two versions.


Can you uninstall the old version, with:

yum remove compat-wxPythonGTK2

If you have applications installed that are depending on this old 
version, I'm pretty sure yum will warn you about that before it 
uninstalls it.


Failing that, I guess you could hand-edit the pykaraoke script and add 
the lines to force the appropriate path to the current wx, so that it 
looks like this:


#!/usr/bin/env python
import sys
sys.path.insert(0,'/usr/lib/python2.4/site-packages/wx-2.6-gtk2-unicode')
import pykaraoke
pykaraoke.main()

Re: [Pykaraoke-discuss] PyKaraoke v0.5 Released

Hi Drew,

Any chance you could temporarily remove the compat libraries to see if 
that's what's causing it?

If it is, then it appears that we can force the Wx version used by 
adding the top two lines below to pykaraoke.py:

import wxversion
wxversion.select('2.6')
import os, string, wx, sys

They may need to be added to pykdb.py as well.

Let me know how you get on,
Kelvin.

Hi David,

I installed the pygame-devel package and tried again.

Everything seemed to go fine this time. It did the compilation step and
exited without any error.

However, I still can't make it run. I get this:

I'm pretty sure that should have been installed with the pygame 
distribution (there's not a separate pygame-devel distribution, to my 
knowledge).  Do you have pygame installed?

This smells like a wxPython version issue.  What version of wxPython do 
you have installed?  Are you able to run the previous version of PyKaraoke?

Hi,
I feel like I'm being slightly thick and asking stupid questions but
here goes :)

I downloaded the big 0.5 and unzipped it, I fully expected to have
everything installed to make it work so typed what I was told in the
README

I take it I need the pygame header file? why haven't I got that?


Also when I tried to run pykaraoke without the compiled C bit I got
this:

Any pointers? my brain is not working overly well today... maybe I
should eat something.

I mean the resolution of the X-server, to fit the movie or so... Because also

Hi Cyrill,


It works now...


Glad to hear it!

Does this change the resolution for playing? 


Sorry, I'm not sure what you mean?

Quite cool... But it would also have worked just with mplayer or so :) But its 
easy to be able to start the movies from the same tool.


This is true. The MPEG support is really just a bonus feature - in 
future I've been planning to add support for external players to the 
GUI. That way you could add support to the database/GUI for a large 
range of movie formats and spawn off an mplayer process to handle them.


All the best,
Kelvin.

Hi Cyrill,


 Available versions:  1.5.3 1.5.5 1.5.6 1.6 1.6.2 ~1.7.1
 Installed:   1.6.2


Is it possible to upgrade to v1.7.1 through this package manager? I see 
it's there but appears to be masked. If not then I'd advise getting the 
latest version from pygame.org. I'm pretty sure MPEG was fixed by v1.7.1.

Hi Cyrill,

Could you check which version of pygame you have installed? I believe 
that MPG support was broken in some of the recent versions of pygame.


Thanks,

Re: [Pykaraoke-discuss] PyKaraoke v0.4.2

[Kelvin Lawson]

It's a good solution for Linux, though I don't think JACK or the other
stuff runs on Win32 though; it's *possible* you could build a similar
kind of toolchain on Win32 though with whatever SDL is using for sound
delivery.


Well I think all of the calls for pitch-shifting so far have come from 
Linux users so this should be OK for now. Built-in pitch shifting could 
be a longer term goal if nothing is available on Windows.



I'd be glad to write up a howto. It was fairly easy to do once I
figured out the little gotchas. I'll post it in the next few days.


Great, thanks.


If that's still true, then yeah, I just need to update the
UpdatedTiles chunk to tell it I've written changes there. Of course,
the way I was doing it, I was just drawing the text on every frame
anyway. I think I saved the rendered text and only changed *it* when
necessary, then blitted it onto the finished output buffer right
before it got displayed.

Bleh. I need to dig some more to remember how I did it :)


OK, let me know if you need any pointers.

Kelvin.

The way I'd gotten it working before wasn't to write on the
cdgSurfArray, just on the finished buffer right before it got sent to
the screen. I think :)

Hey Will, long time no speak.


I've been experimenting a lot lately with trying to get pitch shifting
working, and I've made a pleasant discovery that, at least in Linux,
makes it a snap to implement. I'm totally jazzed about this :)


Yeah I spotted this on your blog the other day. Kudos! This is a great 
solution as it saves reinventing the wheel. Any chance you could post a 
little HOWTO to the list on setting this up? :-)



More directly PyKaraoke-related, I wrote a patch against v0.3 that
added a configurable on-screen display (showing player status, time in
the song, etc.); anybody at all interested in that kind of feature, or
am I just being a showoff at the local shows? :)

I'd need to probably refactor it to work properly in v0.4 since that
introduced the segmented display scheme; though I was just overlaying
FreeType font stuff onto the buffer right before it gets flushed to
the display device, so it may still just apply and work.


If you're modifying the cdgSurfArray, then it just now needs to set 
appropriate bitfields in UpdatedTiles to specify which tiles have been 
modified. Then cdgDisplayUpdate() will automatically work on only the 
updated tiles. If it's not obvious what to do then I'd be happy to do 
the merge.


Thinking about it, it's probably not appropriate to blit the text into 
cdgSurfArray as it would get scrolled if there was any scrolling in the 
CDG. Better to do this to the unscaled_tiles array immediately before 
scaling and output. This way it won't be left hanging around in the main 
cdgSurfArray for use by the scrolling code.

Figuring out how to patch that in front of *one* of the three outputs
of my USB sound output box (much less to control it from my
"dashboard"), will be the hard part.

Nope, it's not Just You.  And I know this because it's so often Just Me.

Indeed.

I'm going to sit down this week, and finally try to comp up what I
think a pro-hoster control front end for pyk oughtta look like; I'll
post it when I'm done, for conversation and attacks.

Sweet!

I've been experimenting a lot lately with trying to get pitch shifting
working, and I've made a pleasant discovery that, at least in Linux,
makes it a snap to implement. I'm totally jazzed about this :)

Since PyKaraoke is using Pygame, which uses SDL, PyKaraoke
automatically uses the "default" ALSA sound device when ALSA is the
configured sound system on the machine.

Enter the Jack Audio Connection Kit: I got that thing fired up, set a
Jack module as the default ALSA device (much simpler than it sounds),
then configure a Patchbay kit (about a two minute process now that I'm
used to it :) so that a sound processor gets exclusive access to the
sound card, everything talks to the sound processor (PyKaraoke,
MPlayer, etc.), XMMS feeds into the sound processor's Crossfader
channel, and suddenly I have all-digital crossfading between sound
sources and pitch shifting for PyKaraoke. Heh. Yay :)

More directly PyKaraoke-related, I wrote a patch against v0.3 that
added a configurable on-screen display (showing player status, time in
the song, etc.); anybody at all interested in that kind of feature, or
am I just being a showoff at the local shows? :)

I'd need to probably refactor it to work properly in v0.4 since that
introduced the segmented display scheme; though I was just overlaying
FreeType font stuff onto the buffer right before it gets flushed to
the display device, so it may still just apply and work.

Kelvin,
 I tried sending th ogg file but sourceforge mail server rejected it as
too big (2.6 MB)

Would you like me to send again to another address?

[Kelvin Lawson]

Well that was fast! 
That fixed it!


Excellent!


Above the pygame.init() call in pycdg.py and it seems to solve the
problem.


If only I'd waited half an hour before releasing v0.4.2 :-) Mind you I'd 
like to do some testing on this before releasing it anyway. It'll go in 
the next version.



I don't have mp3 playback set up, I read in the documentation somewhere
that it required recompiling SDL (and I could be arsed as didn't want to
use mp3 anyway)


Yes it can be a pain on some distros. If you change your mind there are 
some step-by-step instructions on the website that worked on a recent FC 
release.


Thanks for letting me know,
Kelvin.

Well that was fast! 
That fixed it!

I don't know anything about pygame but I blindly copied an pasted:

pygame.mixer.pre_init(44100,-16,2, 1024 * 3)

Above the pygame.init() call in pycdg.py and it seems to solve the
problem.

"scratchy" is a very good way of describing the playback before and now
it sounds normal.

I will send the ogg file off list so that you can test for yourself.
(btw it's not just this file but all ogg files)


A few other thing which may or may not be worth noting:

I don't have mp3 playback set up, I read in the documentation somewhere
that it required recompiling SDL (and I could be arsed as didn't want to
use mp3 anyway)

I'm running Fedora core 4

My python version says:
Python 2.4.1 (#1, May 16 2005, 15:19:29)
[GCC 4.0.0 20050512 (Red Hat 4.0.0-5)] 

SDL-1.2.8-4

Re: [Pykaraoke-discuss] Pykaraoke, ogg and an intro

[Kelvin Lawson]

Hi,

Welcome aboard.

Could you send me the offending ogg file please? I'll see if I can 
reproduce the problem here.


There's a note in the Pygame documentation about "scratchy" playback due 
to a lack of buffering. It's apparently a bug on Windows, and it's also 
not clear if it applies to the mixer.music module, but it might be worth 
a go anyway:


http://www.pygame.org/docs/ref/mixer.html#pygame.mixer.init

The suggestion is to do this before the pygame.init() call:

pygame.mixer.pre_init(44100,-16,2, 1024 * 3)

Cheers,
Kelvin.

nasty things at me if I'm not :)

First a little intro:
A few years ago I got interested in CDG disks and how they work. Long
story short, I ended up learning a bit about it for the few resources
which were available on the internet at the time (it seems much better
these days). I wrote some code (including some to read Q channel data
for some stupid reason) and then gave up without every completing
anything useful.

Recently I've started thinking about making a karaoke device. I started
looking around to see what was available in the open source world these
days and found pykaraoke and cdgtools both very impressive tools.

I've never coded in python before but it all seems very logical when you
start looking at the code.


Anyway on to my main point :)

I was trying not to use mp3 with a view to keeping everything patent
free and open source.

I'm having a small problem with ogg and pykaraoke:

I modified cdgrip.py to work with oggenc by just switching th encoder
line at first I got good cdg files but white noise ogg files. I soon
realised it was an endainness problem. For some reason oggenc seems to
work the opposite way to lame (little endian by default I think) I used
the --raw-endianness 1 switch and it seemed cured.

The problem I'm having now is one of quality when playing the files back
with pykaraoke, there seems to be noticeable distortion in the playback.
This doesn't happen if I play back the encoded ogg in XMMS. 


I wonder if anyone has any idea about what is going on?

thanks in advance..

vv

Sorry for posting "Pykaraoke, ogg and an intro" from the wrong account.
I subscribed with this account and then my mail program posted through
a different one. Hopefully I've corrected that now :)

I did not.

But I *did* buy abour 250 discs off eBay this week, so the issues are
all much more pressing to me now.  :-)

Re: [Pykaraoke-discuss] PyKaraoke v0.4

[Kelvin Lawson]

The changes look fine; it runs fine on this box.


Good stuff.

I'd like to add direct support for archives in pycdg.py as well (some 
players I've seen on Windows can directly support ZIP at least; if I 
drag in the stuff from cdg2bin that adds support for archives, we'll 
have 'em beat with ZIP, .tar.gz, and .tar.bz2 support :) BTW the archive 
support only uses zipfile and tarfile, both standard modules that ship 
with Python. The way current support is written, they're only imported 
when needed, so even on systems that don't support them for whatever 
reason, stuff will still work (you just have to extract it yourself).


Good idea. I use the zipfile module in PyKaraoke but this would be 
useful for the standalone player. My only gripe with zipfile is that it 
doesn't support all ZIP compression formats. PyKaraoke is unable to 
parse a few of the ZIPs that I have. I've been meaning to write a little 
script that scans a directory and rezips them all with the appropriate 
compression format, but it's filed in my ToDo list along with a lot of 
other scripts :-)



But that can be in the next release; this looks good to go :)


Smart. OK I'll see about releasing it over the next day or two.

Kelvin.
