Pdplay?
by Nicola Bernardini 21 Oct '04

21 Oct '04

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear all, at the SOb project (http://www.soundobject.org) we're writing some really cool physical model objects which we are soon going to package and propose to the pure-data externals repository (they are GNU/GPL). However, we now have a problem that we want to solve soon: we need standalone versions of some demo applications (possibly running griPD etc.) we did. It would be nice to have a sort of MaxPlay type of thing (how about PdPlay?). I have some ideas on how to do it and it could be trivial, and therefore it is very probable that someone has already done it somewhere. If no one has done it, I'll hack up one solution and report back to the list as soon as it is done (it is going to be GNU/GPL anyway :). Thank you in advance for all the help you will want to give. nicb +--------------------------------------------------------------------+ |Nicola Bernardini | |E-mail: nicb(a)centrotemporeale.it | |GPG Fingerprint = 6AE6 AF21 E160 D9B3 396E EBAC 906C CFAE 4D65 D910| |Neither MS-Word nor MS-PowerPoint attachments please: | |http://www.fsf.org/philosophy/no-word-attachments.html | +--------------------------------------------------------------------+ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.0 (GNU/Linux) Comment: Made with pgp4pine 1.75-6 iD8DBQE9mf2qkGzPrk1l2RARAqi/AJ92NXY9HoDWlMbRcu59RkUQNH8E7gCeLU07 +ocbGJWYRzzrrdQO/cG0BcM= =TT6i -----END PGP SIGNATURE-----

redundancy - just another sound file player
by Thomas Grill 22 Sep '04

22 Sep '04

Hi all, for all who need it, i throw it into the arena. Maybe some of you want to try it out and comment on it - i currently don't have time to work more on it. I have a video/audio installation (together with Martin Pi, see http://freebitflows.t0.or.at/f/exhibition/corrosion) running right now, which suffers from the fact that i could not get one of the PD sound file players to work reliably, so i wrote one from scratch. Attached is a flext-based sketch for a player with the following characteristics: - uses libsndfile (http://www.mega-nerd.com/libsndfile/) and flext 0.4.6 (http://grrrr.org/ext/flext ) - should read _MANY_ file formats - safe loading/starting (no garbage output) - optimized design for many parallel players - on the fly tuneable buffer settings - double buffering for glitch-free seek and file change - currently no varispeed capabilities - currently lacking diagnosis capabilities It is called sfplay~, a naming which should probably change because it clashes with cyclone.... For the future, either i'm going to modify one of the existing implementations (probably reasdsf~) or (with many more features) incorporate it into the xsample package. best greetings, Thomas

Disapearing lables in version 0.37-1
by lee 05 Jul '04

05 Jul '04

Hello PD devs. If there is a real bug manager besides this mailing list, please point me there and I'd be glad to post this there. I found a reproducable bug where GUI object lables disappear when moving the patch between platforms. I'm using RCS for simple version control on my patches and rsync to move between OS X and Linux and 100% of the time random GUI object lables are gone each time I rsync. The OS X release is the binary disk image and the Linux version is version 0.37.1 TEST1 compiled 22:27:40 Nov 30 2003 -lee

problem with inlet and outlets
by Pontus Nyman 25 Jun '04

25 Jun '04

Hello. Maybe you can help me to solve a strange problem. I have made a kind of audio streaming external for pd. It uses the default signal-inlet to record sound from a microphone (or a file or whatever you want). The external encodes, packs and sends the recorded audio over network (UDP/IP). At the same time it recieves recorded audio from the network. This audio data is decoded and enqueued in a playout buffer and finally put out to different signal-outlets. The strange thing is that I can hear my own recorded audio and I can't understand how that is possible. The recorded audio goes direct to an outgoing buffer (written by me) and from there to the network. I never put it out to any of the outlets. It doesn't come from the playout buffer either. Therefore, I now suspect that I have misunderstood something about pd:s own buffers. I don't want to hear my own recorded audio. Does anyone know what is wrong and what to do about it? Thanks. Pontus

stack checking
by Thomas Grill 24 Jun '04

24 Jun '04

Hi all, there has been some interest in the pyext object lately which doesn't work with vanilla pd very well. This seems to be because PD's built-in stack checking can't cope with PD functions called from a different thread. Following is the diff for *** src/m_obj.c of PD 0.37-1 *** for a different stack checking approach - it's a simple iteration count which should be far more portable. I'm not sure to which value to set the maximum iteration count - it's 1000 for now. Please note, the devel_0_37 branch already has these changes. best greetings, Thomas 11a12,15 > /* T.Grill - define for a modified, more portable method to detect stack overflows */ > #define NEWSTACKMETH > > 258a263,267 > #ifdef NEWSTACKMETH > /* T.Grill - count iterations rather than watch the stack pointer */ > static int stackcount = 0; /* iteration counter */ > #define STACKITER 1000 /* maximum iterations allowed */ > #else 260a270,271 > #endif > 265a277 > 267a280 > #ifndef NEWSTACKMETH 270a284 > #endif 312a327 > #ifndef NEWSTACKMETH 313a329 > #endif 319c335,338 < char c; --- > #ifdef NEWSTACKMETH > if(++stackcount >= STACKITER) > #else > char c; 320a340 > #endif 323a344,346 > #ifdef NEWSTACKMETH > --stackcount; > #endif 330c353,356 < char c; --- > #ifdef NEWSTACKMETH > if(++stackcount >= STACKITER) > #else > char c; 331a358 > #endif 345a373,375 > #ifdef NEWSTACKMETH > --stackcount; > #endif 351c381,384 < char c; --- > #ifdef NEWSTACKMETH > if(++stackcount >= STACKITER) > #else > char c; 352a386 > #endif 355a390,392 > #ifdef NEWSTACKMETH > --stackcount; > #endif 361c398,401 < char c; --- > #ifdef NEWSTACKMETH > if(++stackcount >= STACKITER) > #else > char c; 362a403 > #endif 365a407,409 > #ifdef NEWSTACKMETH > --stackcount; > #endif 371c415,418 < char c; --- > #ifdef NEWSTACKMETH > if(++stackcount >= STACKITER) > #else > char c; 372a420 > #endif 375a424,426 > #ifdef NEWSTACKMETH > --stackcount; > #endif 381c432,435 < char c; --- > #ifdef NEWSTACKMETH > if(++stackcount >= STACKITER) > #else > char c; 382a437 > #endif 385a441,443 > #ifdef NEWSTACKMETH > --stackcount; > #endif

accessing $0 value
by Tim Blechmann 24 Jun '04

24 Jun '04

hi all, is there any way to access the $0 value from within an external? maybe with the t_object variable of each object? if not, i would like to know, if i'm the only one, who finds this quite handy and if it would be worth the effort to implement it (something i would be willing to do)... cheers... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 After one look at this planet any visitor from outer space would say "I want to see the manager."

external cvs access

hi all, i've got some problems to commit changes to the external repository: tim@laptop:~/pd/externals/k_cext> cvs commit k_cext.h timblech(a)cvs.pure-data.sourceforge.net's password: Cannot access /cvsroot/pure-data/CVSROOT No such file or directory i did a clean cvs checkout a few weeks ago ... since i'm able to commit changes to the pd branch on cvs, i'm a bit confused ... can any cvs guru tell me what i'm doing wrong? cheers... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 After one look at this planet any visitor from outer space would say "I want to see the manager."

Making a Video/Graphics friendly Pd.app for MacOS X
by Hans-Christoph Steiner 20 Jun '04

20 Jun '04

So I finally have some time to work on the next versions of the MacOS X Pd.app and I would like to get all of the video stuff integrated so its easy to use and we don't have constant endless threads about getting Gem/Gem2PDP/GridFlow/PDP/PIDIP working. I number of people expressed interest in helping with this, who all is still interested? Here's what I think needs to be done: - pick one system to provide necessary libs for all (I think Fink works best for this) - the package needs to be compilable from lines in a Makefile (This makes complete automation possible) - the code should be in the Pd CVS (This also makes automation much easier. It looks like PDP/PIDIP/GEM2PDP are already there, I don't know where GridFlow is and ideally Gem could be moved back to the Pd CVS since it only really works with Pd anyway) For the long run, it would be ideal if all of the objects in the video libs were compiled as individual files. This makes it much easier for newbies since they you don't have to deal with the .pdrc at all, plus it makes handling name conflicts much easier (there are some in Gem for example). .hc ________________________________________________________________________ ____ There is no way to peace, peace is the way. -A.J.

just another makefile question
by Georg Holzmann 18 Jun '04

18 Jun '04

Hallo! I tried cygwin to compile an external by me on windows (I modified the windows makefile from CVS). But I got some strange problems (everything compiled fine under linux and also with msvc): I have build the dll in the cygwin shell, but when I create the object in PD an error occurs (cygwin1.dll is needed). So I copied cygwin1.dll into c:/windows/system and tried it again, but then my computer was down! Do I always need this cygwin1.dll to load such an external, and where should cygwin1.dll be ? Thanks, LG Georg PS: my windows-makefile: -------------------------------------------------------------- TARGET = holzilib.dll PD_PATH = "c:/pd" SRC = $(shell ls *.c) OBJ = $(SRC:.c=.o) CFLAGS = -DPD -DWINDOWS -Wall -W -Wshadow -Wstrict-prototypes \ -Wno-unused -Wno-parentheses -Wno-switch INCLUDE = -I. -I.. -I../include -I$(PD_PATH)/src # ------------------------------------------------------------- .SUFFIXES: .dll all: $(OBJ) @echo :: $(OBJ) gcc -shared -o $(TARGET) *.o $(PD_PATH)/bin/pd.dll \ `test -f $*.libs && cat $*.libs` rm *.o $(OBJ): %.o : %.c touch $*.c cc $(CFLAGS) $(INCLUDE) -c -o $*.o $*.c clean: -rm *.a *.def *.dll *.o #install-doc: # @test -d $(PD_PATH)/doc/5.reference || mkdir -$(PD_PATH)/doc/5.reference # cp -r ../doc/* $(PD_PATH)/doc/5.reference install: #install-doc @test -d $(PD_PATH)/extra || mkdir -p $(PD_PATH)/extra install *.dll $(PD_PATH)/extra -- "Sie haben neue Mails!" - Die GMX Toolbar informiert Sie beim Surfen!

hi thomas... > in g_array.c, line 928 the variable ret is defined after some > statements which is not conforming to standard c.
