Re: [Pykaraoke-discuss] Progress report
Hi Ken, Sounds excellent, you're bringing it forward significantly. Over the years lots of people have hoped we would add features for professional KJ use. Is it still suitable for home use with the new version or should we split it into two modes (home / KJ)? Best, Kelvin.

Re: [Pykaraoke-discuss] Welcome to the "Pykaraoke-discuss" mailing list
Hi Conor, I wouldn't rule it out but it seems unlikely because PyKaraoke itself is pure Python. Once you disable the C-optimised CDG player, the rest of PyKaraoke is all Python. My money is on SDL/Pygame or some change they have made to an API which has broken software using old APIs. How comfortable are you with Python? I wonder if you could put together a small Python script that calls the relevant SDL/Pygame API to see how it works. Kelvin.

Could be: did you download the SDL_mixer sources and build them yourself? Could be a version mismatch or similar.

Re: [Pykaraoke-discuss] Filename encoding on Linux

I have not > tested it out on other platforms, but I believe since I remain with > str objects, all encoding issues should be effectively bypassed, so it > should work everywhere. This is actually how PyKaraoke used to behave but users with unicode directory names found that the str() conversion made the scan fail. The previous implementation (the same as yours) compared to the new can be seen here: http://pykaraoke.cvs.sourceforge.net/viewvc/pykaraoke/pykaraoke/pykdb.py?r1=1.35&r2=1.36 This fixed scanning of folders with unicode names, and I confirmed it to work on my machine, so I cannot reinstate the str() as is. Is there an alternative patch that would work in both environments? Could it be that the path needs to be encoded using the file system encoding for example (fileList[i].encode(sys.getfilesystemencoding()))?

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.

Has a > developer been found yet? I'm a developer by day and a while ago hacked on > the pykaraoke source to make some improvements for my wife and I's setup at > home. Unfortunately, we never got around to rolling those improvements back > upstream :( sorry. Is there still some active development going on these > days or any high level goals for the project? > 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.

Re: [Pykaraoke-discuss] installation problem on linux
Hi Francesco,
Fedora splits pygame up into a pygame and pygame-devel package. In order to
compile the fast CDG playback module you need to also install the
pygame-devel package.
Thanks,
Kelvin.

From the start I always intended for PyKaraoke to be usable in commercial projects. To that end I deliberately avoided GPL to remove any restrictions / concerns that commercial projects may have about whether they are free to use it. Rather than go with a BSD-style license, however, I settled on LGPL so that anyone could use it within their products but any changes to the core code should be submitted back. Essentially I'm happy for people to use it in any kind of product, but I'd like to encourage people to submit back improvements for everyone else's benefit. My concern about the GPL is that this discourages people from using PyKaraoke as the underlying playback library in their products when I am not interested in forcing people to release all of the rest of their source code just because they combine it with PyKaraoke. Using LGPL restricts the burden of sending code back to only the PyKaraoke code itself. However I can see that there may be an argument for not applying the same license to the GUI itself. While I think the above is a sensible approach for the CDG, KAR etc playback modules it might not necessarily make sense for the GUI. So I am not against applying the GPL to the GUI, but I wanted to let you know my original thoughts from a few years back when I started the project and to gauge general opinion as well. If anyone has any opinion on this then please let us know. Regards, Kelvin. -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

While we're on the subject, I'll chip in with the reason I chose LGPL for PyKaraoke. In the interest of widespread usage of the PyKaraoke modules, I specifically wanted to allow anyone to import and use it within their own applications without fear of having to open up the rest of their code (i.e. the non-PyKaraoke parts). I'm not sure what the consensus is with respect to GPL on whether importing a Python module would cause the rest of your code to be GPL, but for the avoidance of doubt I went with LGPL.

I haven't really followed the progress of GPLv3 - I made PyKaraoke LGPL because it's fairly open and I wanted to encourage people to use it both privately and commercially. I guess it could go mixed license to incorporate your standalone player, or it could be an additional package. If you player requires the PyKaraoke underlying libraries I'd prefer to maintain them in one tree rather than try to maintain separate forks. Look forward to seeing what you have.

Re: [Pykaraoke-discuss] cdgtools - static
Hi Tim, You could ascertain whether it was the MP3 encode by fiddling with the cdgrip() function in cdgrip.py. It saves a raw WAV file, then encodes to MP3. If you're comfortable modifying the Python code then you could try omitting the MP3 encode step to see whether the raw WAV works (you can play WAV files in PyKaraoke but obviously they take up a good deal more room). If endianness is to blame, you can also pass different parameters to lame to swap endianness. Cheers, Kelvin. >> I think it is possible to use cdparanoia for making the >> mp3 files.

There are certain ZIP compression styles which are not supported by Python. Those files cannot be decompressed and hence won't be added to the database. If this is the case you'll see messages about this on the command-line. Someone once sent me a script to rezip an entire set of files into a format more acceptable to Python.

Re: [Pykaraoke-discuss] CDG C implementation
Hi John, > How do I get PyKaraoke to use the C implementation and not the python > implementation. I'm running GNU/Linux. It should build and use the C implementation if you use "python setup.py install" to install it. This must be run with root privs. If you see the message "Using Python implementation of CDG interpreter" on a terminal when you launch it then the above didn't work. Do you still see this message after running setup.py? Cheers, Kelvin. - Check out the new SourceForge.net Marketplace.

Kelvin: did we ever look into > the "break the playback window apart from the management window" thing? The main driving force behind me doing it was to get the player running with Wx 2.8. Some distros are now packing Wx 2.8 as standard and pygame just didn't play well with it at all - splitting the two up looked like a good way to kill two birds with one stone. As I found a workaround for this which fixed the pygame vs Wx 2.8 problem, it wasn't quite so urgent to split the two up. The fix for Wx 2.8 went into the latest release a few weeks ago by the way. Of course it would still be very handy to split them up, but at the moment I'm just too busy to do this myself. I would of course be happy to give hints to anyone who has the time to look into it.

It was the fact that both Wx and Pygame run in the same process. Supporting separate X displays is another good reason for using different processes for the GUI and the players. Short term we could add a small glue layer between the Wx GUI and the players that starts the players in a separate process and communicates via some IPC mechanism. A while ago I knocked something up that used plain old sockets to do this, but didn't end up going further with it. Perhaps it's time to bring that back in. That would certainly please those wanting separate X displays and kill the Wx2.8 compatibility problem. Longer term I'd like to do away with Wx completely though. Can anyone recommend a good alternative GUI framework that's readily available on the major platforms? Does anyone have time to think about such a project? It might be a good time to add some of the pro hosting features that some of you have been talking about. > I may be *finally* about to do something productive with the silly > program; I have a soft-launch gig coming up in January at a restaurant > a friend of mine bought recently.

Thanks for letting us know. > Wxpython has to be ver 2.6. 2.8 gives me type errors I've just committed a fix to CVS for the type error with Wx 2.8 (it seems we were using a variable name that was not allowed as it conflicted with an internal variable name now used by Wx). Although the GUI is working, there seems to be a problem running the players though. They're updating very slowly, at least on my Linux machine here. The players work fine on their own, but not when launched from the PyKaraoke GUI. My suspicion: there is something different about the main loop in Wx 2.8 that means it doesn't coexist nicely with Pygame within the same process. I'd be interested to hear if it works OK on Mac with Wx 2.8. As usual a new version of WxPython has brought with it new incompatibilities... I'm seriously considering shifting to a different framework for the GUI.

Re: [Pykaraoke-discuss] Show the lyrics on an other monitor
Hi Floris,

The playlist GUI (pykaroake.py) calls out to MakePlayer() in pykdb.py to
start the players. This in turn uses either pycdg.py, pykar.py or
pympg.py depending on the songfile type. All of these eventually make
use of InitPlayer() in pykmanager.py to initialise pygame if necessary.
You may find InitPlayer() is a useful place to do something like this.
That said, I don't know whether it is even possible to set the X display
in this way. I strongly suspect that it won't be possible to have the
same process utilising two different X displays (one for WxWidgets and
one for Pygmae), but I don't know what the rules are there with X. It
might be necessary to spawn a new process to handle the player windows
rather than run them as a thread within the existing process. It should
be possible to insert a different interface between the playlist and the
players such that two separate processes communicate using something
like a socket. You'd need to implement two-way communication such that
the playlist can tell the player process to play/pause etc. and when the
song finishes the player can callback to the playlist to notify it.
Hopefully the interface will be clean enough such that you can drop in a
replacement glue layer to handle the interprocess communication
If you're interested in taking this up I'd be happy to provide further
info on how it all fits together.
Kelvin.

Yep, I've seen those invalid commands as well. Maybe I'll add some kind
of universal sanity-checker on the input data.

Re: [Pykaraoke-discuss] pycdg segfault on amd64
Hey Will, > I suspect this is either a numeric thing or a pygame thing -- aren't > there some compiled bits in those libraries for speed purposes on some > systems? I recall having a 64-bit problem myself when I was first > mucking with PyKaraoke myself ;) Yep I believe that one was a pygame vs 64-bit bug. In this case there are no libraries involved, however. It's just our own C module _pycdgAux.c which is reading the CDG bytes read directly from the CDG file. The problem is that it's reading an x,y offset from the CDG file which is outside of the 300x216 screen size, i.e. the data in the file at this location isn't a perfect rip of the original CDG command. The C code was then using this x,y offset to index into an array sized at 300x216. This was what caused the seg fault that Daniel sent the debug info on. It won't necessarily cause a seg fault on all machines though, as I found on my PC. It would have just been stomping on some memory somewhere that it probably shouldn't :-) It turns out that both of these files fail when using the pure Python implementation of pycdg as well, for the same reason: array index out of bounds. I'd better fix that one up too. The lesson here is to sanity-check the CDG commands as they aren't always perfectly ripped. Kelvin. - Using Tomcat but need to do more?

I tried these CDGs on my AMD64 and they worked fine. I guess it's system dependent whether the out of bounds array access will hit somewhere that will cause a seg fault. I did notice that both those files had classic symptoms of errors in rips. Odd bits of graphics the wrong colour etc, which is why I'm pretty sure that these odd pixel values are coming from a very slightly corrupted rip. They both play for a minute or two before one of these out-of-bounds pixel offsets occur. This is pretty common though, so it's a good thing we've nailed it. Thanks for an excellent bug report by the way. There have been mutterings of AMD64 problems since the optimised C version came out, but nothing with all of the detail necessary to fix it, so thanks!

Re: [Pykaraoke-discuss] pycdg segfault on amd64
Hi Daniel, I've been moving house the last couple of weeks so have just got round to looking into this. I originally thought this looked like a sizeof(int) discrepancy somewhere. I thought perhaps one component (pygame, SDL or _pycdgAux.c) had been built as 32-bit, or perhaps one of the underlying libraries is not 64-bit safe in some places. Anyway, on looking into it further I see that the row_index value is 378 (thanks for all the excellent debug info by the way). This is an invalid index into the array, as the CDG screen width and hence cdgSurfarray[][] is only max 300. For some reason this line in cdgTileBlockCommon() is reading an attempt to set pixel offset 378: row_index = ((packd->data[3] & 0x3f) * 6); CDG rips occasionally contain corrupted bytes, so I could well imagine that this could happen on the odd CDG file but it sounds like this probably happens on all files (please correct me if I'm wrong there). Whether it's corrupted data or not, we really should be range-checking the row and column index here anyway. Could you try adding the following lines in cdgTileBlockCommon() please: // 2 lines of current code below column_index = ((packd->data[2] & 0x1f) * 12); row_index = ((packd->data[3] & 0x3f) * 6); // Enter the following 4 lines if (column_index > (CDG_FULL_HEIGHT - 12)) column_index = (CDG_FULL_HEIGHT - 12); if (row_index > (CDG_FULL_WIDTH - 6)) row_index = (CDG_FULL_WIDTH - 6); If it's rogue data, then hopefully this will fix the seg fault. If it's not rogue data and somehow we're reading the CDG data out incorrectly, well we'll find that out. I hope you don't mind trying this out - I do actually have an AMD64 machine here but unfortunately I can't reproduce the problem. Perhaps if you could send the offending cdg+ogg files I could reproduce it. Many thanks, Kelvin. > I've confirmed this with pykaraoke built from current CVS code.

[Pykaraoke-discuss] CDG Player Seg Faults
Folks,
I recently started getting seg faults when running pykaraoke/pycdg from
source. The version installed into /usr was still running correctly, but
I got seg faults when attempting to run from the source directory.
I narrowed it down to the external compiled module (_pycdgAux.c), and
after a recompile ("python setup.py install" in the pykaraoke directory)
it's working again. I haven't done much work with Python C bindings but
I presume this means my Python version has changed and you need to
recompile any bindings when this happens.

I can't help much on the Windows side of things, but it's odd that you're getting this Numeric error. Have you perhaps installed Numeric for a different version of Python? (e.g. installed Numeric for Python 2.3 but are running Python 2.4?) Another point: If you use the compiled version of the CDG player you don't need Numeric, but you need to have a suitable C compiler installed. Again, I haven't done this on a Windows machine, but I'm told you'll need Visual Studio - presumably there's a free version with just the compiler. And you'll need some development libraries, at least SDL-devel. This is a bit more of a pain than just using the uncompiled CDG player which requires Numeric. > I am planning to write my own frontend using perl and the win32 gui > modules with a MySQL db holding all tracks and calling this script when > a song is selected.

Re: [Pykaraoke-discuss] Pykaraoke for OSX
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.

Re: [Pykaraoke-discuss] Newbie
Hi Paul, As you've probably guessed I was away last month so am just catching up on the PyKaraoke mods tonight. > Having no answer I then renamed the individual files to the Track name e.g. mv 80s Hits-Vol000.mpg Don’t\ You\ Want\ Me > > Now when I search for Wham I see two entries in the list for each track. I’m guessing the search matches on both the filename and the track name from the titles. So question the second is:- >2. Can you remove duplicates from the search results? I haven't been able to reproduce this here. I created a titles.txt file with the same keywords for title and artist as are contained in the filename, but it only shows up once. That is certainly the intended behaviour and I'm not sure yet why this happens for you. >3. and subsequently can you display only the filename and artist in > the result list? I was thinking about making it possible to reorder the columns or only show certain ones, but while looking I realised that the column sizing wasn't particularly friendly anyway. What I've done instead is to make the column sizing more sensible so that the filename, title and artist columns always show up without any horizontal scrolling necessary. Long filenames get truncated to make room for the title and artist, but you can resize the columns as you wish. It also doesn't auto-resize every time you change the window size now, so if you resize your columns they'll stay that way until you perform a new search. The sizing is rejigged every time you do a new search because it's based on the length of the strings in the results, so if you have only short strings in the artists column, for instance, then that column will be suitably small. One side effect of these changes is that users who don't use a titles.txt will still see the Title and Artist column in their search results, although they will be small. I figure that we might want to start filling this in with info from ID3 tags in future, though, so it's probably no bad thing. The change is committed to CVS, so it would be good if you could grab it and have a play around with it. It may be that the new results layout fits your needs without adding configuration knobs for hiding or moving columns. As for the duplicate results, could you let me know if you're still getting this problem. I can't reproduce it here so I thought I'd check whether you've made any progress on that since you last wrote. Cheers, Kelvin. - Using Tomcat but need to do more?

Will Ferrell wrote a FAQ on using PyKaraoke together with JACK to support pitch-shifting - this was based on CD+G but it may be possible to use the same framework for MIDI, I'm not sure. Tempo adjustment and muting of instruments, however, is not currently supported and I don't think that we have enough control over the timidity playback engine to do this with the current design.

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.

Judging from the RW_RAW vs RW rip I made, it doesn't look like it's packing the bits together in that way. After looking at a few CDG blocks, it became pretty easy to recognise and pick out the 24-byte CDG packets, and in the RW version it looked very much like 3 CDG packets (with the first 72 bytes exactly the same in both RW and RW_RAW mode). So we have one drive that doesn't include any CDG bytes (the NEC), one which gives 96 bytes but modified audio (Liteon) and one which only gives 72 bytes and does some byte-swapping (CyberDrv). It sounds like we're going to have trouble getting RW mode working reliably on a range of drives, unless we've just been unlucky in our selection of drives. The Liteon seems to be the most promising so far, but I don't see how we can progress with the other two. Perhaps we could find a drive which is known to work in RW mode and continue with that, but meanwhile I'm inclined to agree with Drew that RW_RAW mode is what we should be concentrating on, particularly if it's the case that all CDG-capable drives can do RW_RAW (don't know whether this is true). It would be nice to get some error-correction in there though. Kelvin. Using Tomcat but need to do more? Need to support web services, security?

I've just compared the RW vs RW_RAW output from my drive, and it appears that the RW version has 72 byte CDG sections vs 96 bytes for RW_RAW. I initially thought that must be the 96 bytes of CDG data without the 24 parity bytes, but it turns out that strangely the drive is returning only the first 3 24-byte CDG packets (including the parity bytes), and missing the fourth. So it's only giving me 3 out of every 4 CDG packets in RW mode. It also happens to swap the bytes in every 16 bit word. So it looks like this drive is giving me dud data in RW mode. Maybe it expects to send 72 bytes due to dropping the parity bytes, but just forgets to drop the parity bytes. Given your experience with your NEC drive purporting to send RW data but sending nothing of the sort, I'm thinking that this is an issue with my drive. I'll be interested to hear what you're getting out of your other drive. Hopefully it will either be the full 96 bytes, or 72 bytes but with the parity bytes removed. Cheers, Kelvin.

The abundance of zeroes towards the end of the RW file indicates there might be some data in the RW_RAW file which is missing in the RW file. The RW_RAW file contains 262464 blocks (of 2448 bytes each). The RW file is 641378400 bytes up to the zero section. Assuming the data in the RW file is still 262464 blocks, but with some padding at the end we get between 2443 and 2444 bytes per block. Could it be that the CDG data is in there somewhere, but the parity bytes have been removed or shortened? There are 6 parity bytes per 96 byte block, which makes 2442 bytes per audio+CDG block if the parity bytes were removed. 2443-4 is not far off that, so even though there are a bunch of zeroes at the end there is still enough space up to the zeroes to hold the payload of the CDG data (without some of the parity bytes). Not sure if it's significant but thought I'd mention it as an observation. A useful thing to do with the two rips might be to knock up a little program to compare each of the audio sectors at 2352 and 2448 in turn, until we find the first one that is different. It would be interesting if this was at some significant boundary (say 32 blocks), and if it was followed by some CDG-looking bytes in the RW file. Cheers, Kelvin. Using Tomcat but need to do more?

How about using the RW image you ripped earlier, and searching for some of the CDG bytes you can see in the RW_RAW version? If a number of 96 byte CDG blocks are grouped together somewhere, we might be able to find the location this way. Kelvin. Using Tomcat but need to do more? Need to support web services, security?

If you have time, it would be good if you could pick any disc and do a rip in both RW and RW_RAW mode, and send along the first 100KB or so of each rip. Kelvin. Using Tomcat but need to do more?

I certainly didn't expect the audio to be affected by using RW mode. I'm inclined to go with your reason 3 as well - that the data is not arriving in the expected order. Could the CDG data be smaller because the parity bytes have been removed? From reading about other people who have tackled the software-deinterleave process (e.g. the Audiograbber guy) my understanding was that this was a pain-in-the-ass that you can avoid by using RW drives. I'd be surprised if there was anything particularly complicated to do so we must be missing something simple. You said you looked at the bin file - did you compare it with the RW_RAW output from the same disk? If you have an example of the first few KB output using both modes I'd be interested to see it.

I'm not so sure about this because some Windows CDG rippers boast of their software deinterleaving support. They say that some drives can return the CDG data ready-deinterleaved, while others need an extra software deinterleave. Check out the following message from the Audiograbber author (make sure you also scroll down to look at his reply about the deinterleave process): http://www.karaokeplayground.co.uk/ubbcgi/ultimatebb.cgi?ubb=print_topic;f=9;t=001020 > Have you noticed that the 24 byte DG packet contains 6 "parity" > bytes it would be nice if these could be used to correct broken cdg > files. Definitely worth a try. According to the Audiograbber author's message above he gets more errors when using software deinterleave as the deinterleave-capable drives seem to be error-correcting. I guess we're missing that stage in the software-deinterleave. Apologies for the tardy response by the way, I tend to work on this in bursts. Kelvin.

Re: [Pykaraoke-discuss] New ripper
Hello Folks, Thanks a lot for posting your code Drew, glad to hear you got it working. If you don't want the hassle of packaging it up yourself in a release it sounds like a good addition to the cdgtools suite. I tend to use Python for home projects simply because I find it quicker to get something functional, but I see no reason why C code shouldn't go into cdgtools. Let me know if you're interested (cdgtools is LGPL by the way). > It decodes the q channel and checks to see if the track number has > changed. > > If it has the program then does a CRC check (there is a CRC value built > into the q channel) and if the CRC is bad the change of track is > ignored.

I just had a look through the cdrdao man page and to my surprise there doesn't seem to be an option to rip single tracks. Anyone know of any other suitable rippers? >>Yeah, drives are very random and finicky about this part of things. >>Figuring out whether you've been handed raw or cooked subchannel data >>is a pain in the [EMAIL PROTECTED] :) > > I'm not totally convinced that it's just a drive problem. Has anyone on > the list every got RW data to work? My drive returns the data interleaved, so I've only ever tested rw_raw mode (using the software-deinterleave) hence the note of caution in the instructions for rw mode. My thinking was that the data returned in rw mode would need nothing doing to it at all, it could be written straight out to the CDG file as it came from the CD drive. Have you found this not to be the case? Could it be that the drives concerned don't support rw mode? Cheers, Kelvin. All the advantages of Linux Managed Hosting--Without the Cost and Risk!

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. --- Using Tomcat but need to do more?

Re: [Pykaraoke-discuss] [HOWTO] Implementing pitch-shifting and crossfading (for filler music/other sources) for PyKaraoke on Linux with JACK
I'd need to rewrite it in C but it should translate fairly easily, especially given what we now know about CD+G. Which, presumably, is more than you did before the first cut. :-) Yeah, it was easy enough to knock something up that worked on my small collection of tracks, but since then I've had a few people (you included) send me CD+Gs that interpreted the spec differently. It's been all quiet for some time now, so it must be perfect . Hmmm... Is there a standardized way to get raw tracks off a Redbook CD in Linux? Doesn't XMMS do some of this? Pass. When I wrote cdgtools, the only useful tool I could find for reading subchannel data was cdrdao. We can presumably package up ATAPI commands and pass them to the relevant Linux driver, but cdrdao might take away the pain of handling a range of drives with different supported commands etc. rip just the CD+G data without any MP3 encoding. You can then play this back as usual with pycdg.py while the CD track plays. Should be relatively quick to implement but you pay the price of the time spent doing the rip before playback. Could you sync it, though? Well there's the new "no audio" option in pycdg. This uses the system clock to play the CD+G in real time. It would need to know if you had paused or rewound etc, but it could probably do the job. You can also poll the pygame CD playback to find out the current playtime but it's only one second accuracy.

Re: [Pykaraoke-discuss] subcode and deinterleaving question
Hi Drew, I've been reading all the info I can find but I must admit I'm getting a little confused partly because the terms "frame" and "sector" do not seem to be used consistently. For instance the ECMA-130 standard seems to refer to 588 bits burnt on to the disk as a frame. Thanks for the headsup, I hadn't seen that ECMA 130 before. I thought the gory details were to be found in the Red Book which costs money, so it's great to find this info available for download. I've just had a scan through it, and it distinguishes between sections, sectors and frames. We've used sector and frame to describe the same thing in the cdgtools code - as the 2352 bytes of audio + (2 * 392) bytes error correction/detection + 98 bytes subchannel data. Looks like we should replace "frame" by "sector" throughout the code. Some of the above is filtered out to get the data returned by cdrdao. We get the 2352 bytes of audio data, plus 96 bytes of subchannel data. (The first two bytes of subchannel data appear to be sync bytes, hence getting 96 instead of 98). The subchannel data is contained in the "control byte" discussed in the document. I know a certain amount of interleaving goes on in the audio data prior to it being written onto the disk but I was under the impression that the same could not be said about subcode? It looks that way from the document. The CIRC coding is done before the control bytes are added, but perhaps the control bytes are then added in the relevant place, i.e. they are not added in order because they are placed according to the position of the CIRC-encoded data? I haven't read deeply enough yet to figure that out. As you can probably tell from the above, I'm pretty much in the dark about the interleaving process. When writing cdgtools I noticed that my drive was returning data that looked almost correct but with the bytes spread around. I couldn't find any information on the interleaving process, and believed it to be in the Red Book, but came across the following: http://club.cdfreaks.com/showpost.php?p=719361&postcount=13 This guy was in the same position as me, but had the patience to sit down and reverse engineer which bytes went where. Is it just the r to w channels which are interleaved or is it the whole subcode byte? (including the p and q channels). I'm not sure because I mask out only the P and Q subchannels. Are you asking because the CIRC section discusses encoding of P and Q bytes? The way I read that was that these are parity bytes, unrelated to the p-w subchannels (confusing terminology). My (probably flawed) thinking is that the control bytes containing subchannel data are not put through the CIRC process, but are matched up with the new position of the relevant frame after CIRC encoding, and so are effectively interleaved. Bear in mind I don't even know if the deinterleaving code in cdgtools is actually reversing the CIRC cross-interleaving, or if it's some other magic altogether. It would be great if you had the time and inclination to check this out :-) Hope that helps, Kelvin. --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.

Re: [Pykaraoke-discuss] [HOWTO] Implementing pitch-shifting and crossfading (for filler music/other sources) for PyKaraoke on Linux with JACK
In fact the only missing piece apart from digital mixing is a lack of straight-from-CD CD+G player, which is something I'm interested in doing anyway, and I think Python can do it. Any hints or thoughts, Kelvin? I've given it some consideration in the past but not in great detail. Pygame can play audio tracks on a CD but (unsurprisingly) there is no facility to read the subchannel data. Initial thoughts on the simplest thing to implement would be to combine a cdrdao/cdgrip pass with pygame's CD playback. It's just a hack but it buys you something. After selecting a track, you spawn off a process to rip just the CD+G data without any MP3 encoding. You can then play this back as usual with pycdg.py while the CD track plays. Should be relatively quick to implement but you pay the price of the time spent doing the rip before playback. Doing it *properly*.. that's a different thing. I don't know, for instance, what the usual method would be for extracting the subchannel data on Linux. Whether you'd need to use a library like cdrdao, or whether it's just as easy to get what you need straight from the OS. I'm thinking something like Python bindings for cdrdao to read the subchannel data - and if you're doing this in real time then presumably you'd want to read the audio data at the same time, rather than have two proceses seeking around the disk. I'd need a deeper look into the likes of cdrdao to comment any further than that. The link is Coral Cache-ified by the way because I'm expecting heavy traffic in a few days; a not-so-friendly company is threatening to sue me because I posted my experience with them on my site, and negotiations broke down recently. I went public with the details, and Tom Martino (the "Troubleshooter") is going to have me on his radio program Monday to hash this stuff out. Heh.

I've fancied doing this for some time but haven't got round to it yet. Making an mplayer/ffmpeg codec would give you CD+G for free with a whole bunch of video players, as well as those commercial DVD players and other devices that use ffmpeg.

Re: [Pykaraoke-discuss] PyKaraoke v0.4.2
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.

Re: [Pykaraoke-discuss] PyKaraoke v0.4.2
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.

Drew wrote: Hello, I hope I'm posting this to the right list, feel free to shout 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.

Re: [Pykaraoke-discuss] Fast chirping sound when tryingt to play a song
Hi Harry, We recently had some trouble getting the graphics to sync up with the audio on lower spec machines. We made a lot of improvements but I'm not convinced that would extend down to 400MHz. That said, I'm surprised it's the audio that's failing. On Windows you should get better results from an application that takes advantage of hardware accelerated graphics etc. PyKaraoke currently takes advantage of Python and some Python-based libraries so that we can run the same code on many platforms. Unfortunately this raises the bar a little in terms of minimum requirements, and I suspect that a 400MHz machine will not be suitable. All the best, Kelvin.

[Pykaraoke-discuss] Re: RPM for v0.4.1
Hi Chris, ...Sorry, I think I mis-spoke (mis-wrote). What I meant by this is that the RPM installs just fine (I know you need root privileges for that). I meant to say that PyKaraoke itself, when installed from the RPM, runs as expected only when logged on as root. If you try and run it as a normal user, it errors out. By contrast, the non-RPM installed version appears to work on FC4 with normal user rights. Ah apologies, I misread your message. Hopefully this will be fixed in the new RPM. I used to make distutils build a ZIP file for the source, but that trashed all the file permissions etc. It may be that this also affected the RPM I built then. With any luck this problem will have gone away now that I've told distutils to use a tar.gz. Hope that helps and thanks! I'll try the updated RPM in a bit - I just got "that little talk" from my wife about being on the computer... :) Oh I know that talk only too well.

Re: [Pykaraoke-discuss] RPM for v0.4.1
Hi Chris, I tried downloading the RPM. It seems for some reason that Firefox and Konqueror on FC4 wants to recognize it as a RealPlayer type file and opens it with a media player instead of saving the file. I know there's a way to specify a preferred mime type with the file on the Web server, but I don't remember off hand how to do it. VMware has the same problem by the way when downloading their RPMs. They really need to fix it. Thanks for letting me know. I've added a .bin extension on there now: http://www.kibosh.org/pykaraoke/pykaraoke-0.4.1-1.noarch.rpm.bin If you still have no luck maybe you could grab it with wget. Also, I noticed the other day that the first RPM file installs and runs properly on FC4 as long as you are root, but doesn't work properly with normal user rights. I'll see if I can dig up the exact error next opportunity. It needs to run as root so it can install into /usr/bin and friends. Thanks for giving it a go, look forward to hearing how it goes.

[Pykaraoke-discuss] PyKaraoke v0.4.1
Hi Folks, I've just released v0.4.1 of PyKaraoke. Thanks for all your patches and testing. Main changes are: * Better pycdg performance through tiled scaling/blitting. * Linux install script (run "python setup.py install"). * A few GUI fixes for wx-2.6, and MIDI playback within ZIPs. The full changelog is here: http://sourceforge.net/project/shownotes.php?group_id=123242&release_id=381511 I've defaulted the frames per second to 10, with the expectation that those that want higher can use the --fps parameter. I'll add a configuration knob for this to the GUI in the next release. I'd like to see about getting this release into the distro package managers so if anyone can help with testing out debs and rpms that would be good. I'll create an RPM and send it out soon.

Re: [Pykaraoke-discuss] Re: FINALLY -- ghod I hate SuSE
Hi Jay,
This version seems also to keep up, and only boosted my load average
from .44 to .88 or so. I think that's better. :-)
Sounds like a goer to me.
As we got a decent improvement out of 4 tiles, I've had another bash at
it tonight. The attached version uses 24 update tiles (a grid of 6x4).
If anyone gets the chance, could you try it out and let me know the
results. If all goes well I'll see about putting out a new release
towards the end of the week.

# OVERVIEW
#
# pycdg is a CDG karaoke player which supports MP3+G and OGG+G tracks.
#
# The player uses the pygame library (www.pygame.org), and can therefore
# run on any operating system that runs pygame (currently Linux, Windows
# and OSX).
#
# You can use this file as a standalone player, or together with
# PyKaraoke. PyKaraoke provides a graphical user interface, playlists,
# searchable song database etc.
#
# For those writing a media player or similar project who would like
# CDG support, this module has been designed to be easily incorporated
# into such projects and is released under the LGPL.
# REQUIREMENTS
#
# pycdg requires the following to be installed on your system:
# . Python (www.python.org)
# . Pygame (www.pygame.org)
# . Numeric module (numpy.sourceforge.net)
# USAGE INSTRUCTIONS
#
# To start the player, pass the CDG filename/path on the command line:
# python pycdg.py /songs/theboxer.cdg
#
# You can also incorporate a CDG player in your own projects by
# importing this module. The class cdgPlayer is exported by the
# module. You can import and start it as follows:
# import pycdg
# player = pycdg.cdgPlayer("/songs/theboxer.cdg")
# player.Play()
#
# The class also exports Close(), Pause(), Rewind(), GetPos().
#
# There are two optional parameters to the initialiser, errorNotifyCallback
# and doneCallback:
#
# errorNotifyCallback, if provided, will be used to print out any error
# messages (e.g. song file not found). This allows the module to fit
# together well with GUI playlist managers by utilising the same GUI's
# error popup window mechanism (or similar). If no callback is provided,
# errors are printed to stdout. errorNotifyCallback should take one
# parameter, the error string, e.g.:
# def errorPopup (ErrorString):
# msgBox (ErrorString)
#
# doneCallback can be used to register a callback so that the player
# calls you back when the song is finished playing. The callback should
# take no parameters, e.g.:
# def songFinishedCallback():
# msgBox ("Song is finished")
#
# To register callbacks, pass the functions in to the initialiser:
# cdgPlayer ("/songs/theboxer.cdg", errorPopup, songFinishedCallback)
# These parameters are optional and default to None.
#
# If the initialiser fails (e.g. the song file is not present), __init__
# raises an exception.
# IMPLEMENTATION DETAILS
#
# pycdg is implemented as one python module. It performs all
# of the CDG file decoding locally, and gets audio playback
# and video display capabilities from the pygame library.
# It also uses the python Numeric module, which provides
# fast handling of the arrays of pixel data for the display.
#
# All of the information on the CDG file format was learned
# from the fabulous "CDG Revealed" tutorial at www.jbum.com.
#
# The player is run within a thread to allow for easy
# integration with media player programs. The thread starts
# the pygame MP3/OGG playback, and then monitors the current
# time in the song. It reads the CDG file at the correct
# location for the current position of the song, and decodes
# the CDG commands stored there. If the CDG command requires
# a screen update, a local array of pixels is updated to
# reflect the new graphic information. Rather than update
# directly to the screen for every command, this local array
# is output to the screen ten times per second (configurable).
# Doing an actual screen refresh for every command consumes
# a lot of CPU horsepower.
#
# NOTE: Pygame does not currently support querying the length
# of an MP3 track, therefore the GetLength() method is not
# currently implemented.

Re: [Pykaraoke-discuss] CAVS' "Super CD+G" format
Any insights here would be welcome. I infer from the patent that if I can get to MCG files, they might be reasonably parseable with the current engine... I'd definitely like to learn more about this. Do you know if any players other than CAVS have managed to decode it? I haven't heard of any. I'd also like to add .kok and .lrc support, though those are probably less interesting to you KJs. Which reminds me... I set up a little wiki page to note down requested features for PyKaraoke. If you'd like to add anything (or even better tick some off the list :-)) it's at: pykaraoke.wikispaces.com Feel free to chip in, add a separate section for a professional player etc. Kelvin. --- This SF.net email is sponsored by: Splunk Inc.

Re: [Pykaraoke-discuss] Re: FINALLY -- ghod I hate SuSE
This one (I'm calling it pycdg3.py) keeps up with the Doobie Brothers
track at full screen size, with no changes. The noticeable pause seems
gone, and my load average went from ca .61 to ca 1.25 on this C-IV
1400.
Fab! Now the question is, was it the reduced display update mods, or the
removed delay that made it better. Sorry to have you trying out all
these versions, but if you could try out the attached version (with the
delay back in) we might be on the home straight :-)
If it is the delay, it might explain why I haven't had any reports of
syncing problems in the past. The delay code was a fairly late addition.
Noice.
I'll say.
Well, remember, it may *take* 100% of available CPU; that's ok. The
question is, what does it do when something else is running.
And if it turns out to be the delay causing problems, I'll need to find
some other solution to stop it using 100% CPU when it's not actually
doing anything.

Re: [Pykaraoke-discuss] *Creating* CDG files
Anyway, the format's pretty simple, so generating the final output isn't too hard. It's coming up with what to show in the first place that's the challenge :) It basically just means coming up with a decent palette (fairly easy), picking a readable but fast-to-display font, and timing things so the words are on the screen *before* they need to be sung and getting them to highlight as they're sung. 'tis fun :) Kelvin probably has more input, too :) I agree. Given our experience from pycdg, generating the correct CD+G commands shouldn't cause us any difficulty. I reckon the main effort would be in creating the GUI to control it all, building up the on-screen graphics etc. I don't get much pleasure from writing GUI applications, but if someone was interested in developing that side I'd be happy to help out with the CD+G generation side.

Oh, it's definitely better, It's not perfect, but it's imperfect in a substantially less annoying way. :-) This is good news. If I get the chance tomorrow I'll split the screen up into more tiles and maybe we can squeeze some more performance out. I'd be interested to hear how the new version goes, to see whether the delay was causing any damage. I'd like to put that back in otherwise we'll end up with reports of 100% CPU usage.

Re: [Pykaraoke-discuss] Re: FINALLY -- ghod I hate SuSE
Hi Jay,
Thanks for the feedback. So do you think this is an improvement on the
previous performance? If it's difficult to tell with the new 1/4 second
display-dropping code then let me know and I'll take it out.
If it's an improvement then maybe the thing to do is divide the screen
into smaller segments.
I've made a few updates tonight, if you could help by trying them out
that would be great. Although the last version only scaled the modified
tiles, it still did a full update() on the entire screen. This one only
updates the modified tile.
I've also removed a small delay that was in there to reduce CPU load
(which stops it constantly polling for the current song time). I'm
wondering whether some systems can hit this and block for a long time,
doing no work at all. It will take your CPU load up to 100% if it wasn't
already.
I also added some profiling code in there using the hotshot module. It
hasn't turned out to be useful unfortunately - according to the
documentation it doesn't play well with threads. The accumulated time it
spews out is totally incorrect for instance. I've disabled it in there
for now.
Cheers,
Kelvin.

out the attached pycdg.py please? Basically I've just divided the screen
into four segments. I now only do the scaling on the segments that have
been updated. I'm not sure how it will pan out, so before I tidy it up
and do it properly, could you give this one a go? FPS is set to 30.
That first draft was a little rough round the edges. Amongst other
things, it didn't update the screen on Preset commands. I've attached
the latest version for your testing pleasure.
Beware that this one includes some code to bar any screen updates if the
decoding gets 1/4 second behind the music. I figure the best thing to do
in these situations is to not add insult to injury by carrying on
performing slow output scaling. If there's a spell of heavy CPU activity
it'll stop doing any updates, allowing the CPU to catch up quicker. The
thinking is that a spell of no updates is better than a spell of out of
sync updates.
Cheers,
Kelvin.

# OVERVIEW
#
# pycdg is a CDG karaoke player which supports MP3+G and OGG+G tracks.
#
# The player uses the pygame library (www.pygame.org), and can therefore
# run on any operating system that runs pygame (currently Linux, Windows
# and OSX).
#
# You can use this file as a standalone player, or together with
# PyKaraoke. PyKaraoke provides a graphical user interface, playlists,
# searchable song database etc.
#
# For those writing a media player or similar project who would like
# CDG support, this module has been designed to be easily incorporated
# into such projects and is released under the LGPL.
# REQUIREMENTS
#
# pycdg requires the following to be installed on your system:
# . Python (www.python.org)
# . Pygame (www.pygame.org)
# . Numeric module (numpy.sourceforge.net)
# USAGE INSTRUCTIONS
#
# To start the player, pass the CDG filename/path on the command line:
# python pycdg.py /songs/theboxer.cdg
#
# You can also incorporate a CDG player in your own projects by
# importing this module. The class cdgPlayer is exported by the
# module. You can import and start it as follows:
# import pycdg
# player = pycdg.cdgPlayer("/songs/theboxer.cdg")
# player.Play()
#
# The class also exports Close(), Pause(), Rewind(), GetPos().
#
# There are two optional parameters to the initialiser, errorNotifyCallback
# and doneCallback:
#
# errorNotifyCallback, if provided, will be used to print out any error
# messages (e.g. song file not found). This allows the module to fit
# together well with GUI playlist managers by utilising the same GUI's
# error popup window mechanism (or similar). If no callback is provided,
# errors are printed to stdout. errorNotifyCallback should take one
# parameter, the error string, e.g.:
# def errorPopup (ErrorString):
# msgBox (ErrorString)
#
# doneCallback can be used to register a callback so that the player
# calls you back when the song is finished playing. The callback should
# take no parameters, e.g.:
# def songFinishedCallback():
# msgBox ("Song is finished")
#
# To register callbacks, pass the functions in to the initialiser:
# cdgPlayer ("/songs/theboxer.cdg", errorPopup, songFinishedCallback)
# These parameters are optional and default to None.
#
# If the initialiser fails (e.g. the song file is not present), __init__
# raises an exception.
# IMPLEMENTATION DETAILS
#
# pycdg is implemented as one python module. It performs all
# of the CDG file decoding locally, and gets audio playback
# and video display capabilities from the pygame library.
# It also uses the python Numeric module, which provides
# fast handling of the arrays of pixel data for the display.
#
# All of the information on the CDG file format was learned
# from the fabulous "CDG Revealed" tutorial at www.jbum.com.
#
# The player is run within a thread to allow for easy
# integration with media player programs. The thread starts
# the pygame MP3/OGG playback, and then monitors the current
# time in the song. It reads the CDG file at the correct
# location for the current position of the song, and

Let me confirm this: *you're* doing the scaling, manually? I would
have thought the {mumble} library was doing it for you?
Semi-manually. I paint into unscaled segments and then call
pygame.transform.scale() at update-time which does all the scaling for
you. I'm not aware of any pygame feature that auto-scales your output
surface.
Previously I scaled up the entire surface on every update. Now I'm only
scaling up the segments that have changed, leaving the other segments
totally unmodified and unscaled.
With four segments this should give us an *up to* 4x performance
improvement in the scaling part of the code. Thanks to the fact that
CD+G tends to roll across the screen it's not very often that you'll
have to scale more than one segment in one update.
Kelvin.

I've downloaded it; I'll check it today. Saw your note about depth; I'll play with that too. Cheers, looking forward to hearing from you. If it's an improvement but still not quite enough, I can divide the screen into smaller segments. If it's worse.. well at least we tried. Kelvin. --- This SF.net email is sponsored by: Splunk Inc.
