PD compile on Mac Pismo?
by vze26m98 03 Mar '05

03 Mar '05

Hi all- Recently upgraded my Mac Pismo from Debian 2.4 to 2.6.8 and have installed the ALSA drivers instead of OSS. I've got tcl8.3 and libgtk1.2 installed along with the dev packages. gcc is 3.3.5 When I was running 2.4, I had successfully compiled PD-0.38-0 and was running it. Now after upgrading and configuring with './configure --enable-alsa', I get the following message from PD at launch: >vatic:/usr/local/src/pd-0.38-0/bin# ./pd -noadc >priority 98 scheduling enabled. >memory locking enabled. >priority 96 scheduling enabled. >memory locking enabled. >Xlib: connection to ":0.0" refused by server >Xlib: No protocol specified > >Application initialization failed: couldn't connect to display ":0.0" >watchdog: signaling pd... I checked the output of ./configure for anythin untoward, but didn't see anything. Here's the GUI portion: >checking for X... libraries /usr/X11R6/lib, headers /usr/X11R6/include >checking for XCreateWindow in -lX11... yes >checking tcl.h usability... no >checking tcl.h presence... no >checking for tcl.h... no >checking tcl8.7/tcl.h usability... no >checking tcl8.7/tcl.h presence... no >checking for tcl8.7/tcl.h... no >checking tcl8.6/tcl.h usability... no >checking tcl8.6/tcl.h presence... no >checking for tcl8.6/tcl.h... no >checking tcl8.5/tcl.h usability... no >checking tcl8.5/tcl.h presence... no >checking for tcl8.5/tcl.h... no >checking tcl8.4/tcl.h usability... no >checking tcl8.4/tcl.h presence... no >checking for tcl8.4/tcl.h... no >checking tcl8.3/tcl.h usability... yes >checking tcl8.3/tcl.h presence... yes >checking for tcl8.3/tcl.h... yes >checking for main in -ltcl8.7... no >checking for main in -ltcl8.6... no >checking for main in -ltcl8.5... no >checking for main in -ltcl8.4... no >checking for main in -ltcl8.3... yes >checking for main in -ltk8.7... no >checking for main in -ltk8.6... no >checking for main in -ltk8.5... no >checking for main in -ltk8.4... no >checking for main in -ltk8.3... yes >.................... alsa= yes >checking for snd_pcm_info in -lasound... yes >checking for shm_open in -lrt... yes >checking for jack_set_xrun_callback in -ljack... no >checking for jack_set_error_function in -ljack... no >OPT_CFLAGS --------------- -O6 -funroll-loops -fomit-frame-pointer >configure: creating ./config.status >config.status: creating makefile Anyone have an idea about what's going on?

OpenAL with Pd? ...similar to Gem?
by Mike Wozniewski 03 Mar '05

03 Mar '05

Hi all, I was wondering if there has been any effort in developing OpenAL objects for Pd? The 3D spatialization features of OpenAL are quite interesting to our group, and we are thinking of ways to direct Pd audio signals to an OpenAL output engine. I thought I'd ask first if anyone has tried anything of this sort before? There should also be some interaction with Gem in this case - because OpenAL is heavily influenced (in terms of syntax and model) by OpenGL, and users would probably like to use the two together. For example, we are creating a virtual 3D world where sound objects are graphically represented with Gem, and hence their audio would be spatialized in the same 3D coordinate system. The first fundamental obstacle that we see is that of resource management. ie, which engine should have access to the soundcard drivers? OpenAL has sources, and listeners. For sources, we can simply stream a Pd audio signal into an OpenAL buffer queue. This should be easy since these buffers live in regular memory. But listeners are a function of the soundcard, channel specifications, and speaker setup. This is more low level and might conflict with Pd. Any thoughts? ...thanks in advance for any comments! Cheers, -Mike Some references: Full user-guide: http://www.openal.org/openal_webstf/specs-annote/oalspecs-annote.pdf OpenAL explained: http://www.linuxdevcenter.com/pub/a/linux/2000/10/13/oa_openal.html

gem video mixing does not work as before?
by beau25＠access4less.net 03 Mar '05

03 Mar '05

Hello Max Neupert I'm not really sure what system your on, but I have had some success with alpha mixing using win2k gem 0.9 with pd 3.7 (haven't tryed 3.8 yet), and planet ccrma redhat 9 pd gem install. Alpha mixing can provide the classic crossfade between two sources, or were you trying for some other type of mixing such as masks ect. Try this alpha mixing patch (also located @ http://geocities.com/recursionvideolab/videomixer.zip): #N canvas 145 255 821 361 12; #X obj 198 19 gemhead; #X floatatom 310 198 5 0 0 0 - - -; #X obj 199 -22 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 1 1; #X obj 163 72 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 1 1 ; #X obj 495 32 gemhead; #X floatatom 583 206 5 0 0 0 - - -; #X obj 505 3 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 1 1 ; #X obj 507 135 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 1 1; #X obj 369 104 hsl 128 15 0 127 0 0 empty empty empty -2 -6 0 8 -262144 -1 -1 2600 1; #N canvas 128 333 514 308 xfade 0; #X obj 80 18 inlet; #X obj 80 223 outlet; #X obj 169 224 outlet; #X obj 80 81 - 127; #X obj 80 108 abs; #X obj 80 140 / 127; #X obj 169 34 / 127; #X floatatom 80 170 5 0 0 0 - - -; #X floatatom 169 172 5 0 0 0 - - -; #X msg 80 196 1 1 1 \$1; #X msg 169 196 1 1 1 \$1; #X connect 0 0 3 0; #X connect 0 0 6 0; #X connect 3 0 4 0; #X connect 4 0 5 0; #X connect 5 0 7 0; #X connect 6 0 8 0; #X connect 7 0 9 0; #X connect 8 0 10 0; #X connect 9 0 1 0; #X connect 10 0 2 0; #X restore 394 134 pd xfade; #X msg 372 19 open \$1; #X obj 358 -7 openpanel; #X obj 385 -31 bng 15 250 50 0 empty empty empty 0 -6 0 8 -262144 -1 -1; #X msg 664 48 open \$1; #X obj 667 14 openpanel; #X obj 673 -17 bng 15 250 50 0 empty empty empty 0 -6 0 8 -262144 -1 -1; #X obj 538 160 alpha; #X obj 306 66 t f b; #X obj 174 149 alpha; #X obj 643 86 t f b; #X obj 554 127 pix_texture2; #X obj 58 156 gemwin; #X msg 94 103 create; #X msg 12 47 destroy; #X obj 19 90 tgl 15 0 empty empty empty 0 -6 0 8 -262144 -1 -1 0 1 ; #N canvas 559 305 674 311 color 0; #X msg 25 156 color \$1 \$2 \$3; #X obj 25 120 pack 0 0 0; #X obj 25 191 outlet; #X floatatom 25 70 5 0 0 0 - - -; #X floatatom 57 87 5 0 0 0 - - -; #X floatatom 90 104 5 0 0 0 - - -; #X obj 100 121 t b; #X text 24 13 color R G B - the Red Green and Blue values range from 0 to 1 in floating point.

sending 'vnext 0' to pointer
by ggkarman＠musicologia.com 03 Mar '05

03 Mar '05

Hi list, I finally figured out what sending "vnext 1" to a pointer does, but: does anyone know the difference between "vnext 0" and just sending "next"? They both do the same as far as i can understand! I could not find anything on the list on using this message with pointer. Thanks in advance. Greg.

capture avi
by beau25＠access4less.net 03 Mar '05

Hello manuel knapp, There are some programs that will capture a from, but it takes a lot out of your system and the quality is quite poor. I recommend getting a hardware scan convertor, if your computer doesn't have a video out (s or composite). You could also buy a new video card, which would also enhance gem and while getting you a recordable video out. Maybe also try aiming a camera at the screen? To just get a still image out of gem, you could press the print screen button. www.cypod.co.nr

Everything means Zexy, miXed, xsample, PDP, PiDiP, cxc, and some others. It may have something to do with my configuration. IIRC, I couldn't get bootstrap to work, but ran autoconf configure, make, make install. I'm not sure what the build system for devel looks like these days, so I may or may not have done it correctly. But it did build without errors. Sorry I can't be more help. -I -- http://www.0x09.com

[pmpd] - meaning of messages
by Frank Barknecht 03 Mar '05

03 Mar '05

Hi, I have a couple of questions regarding the [pmpd] object. It is not quite clear to me, what the messages to this object mean exactly. Actually I'm very confused about them. As I see it, there are basically four messages possible to create the dynamic system: mass, link, in, out. All of these take IDs as arguments. I don't understand the meaning of those IDs. For example to create a mass, one uses messages like: mass ID MASS X MASS and X are easy, but what is this "ID" used for? "link" also takes IDs as argument, but it seems to ignore the ID given to a mass on creation, instead it seems to use its own IDs and it has an ID itself: link LINK-ID MASS1-ID MASS2-ID K D Where do I get the mass IDs from? In my experiments, it seems just have to keep track of them myself, and they have nothing to do with the ID I gave to a mass earlier. Or do I get it wrong? Outlet creation (and inlet creation respectively): As I understand it, the format is: out OUT-ID OUTLET MASS-ID AMPLITUDE AMPLITUDE seems to be a scaling factor. OUT-ID I don't understand at all: what use does it have? Am I right to assume that OUTLET is numbered from 0 to max-outlet-number, where max-outlet-number is the second argument of pmpd minus one? And then MASS-ID: Does it start from 0 as well? Or from 1? Where do I get this ID from? In my experiments, it seems to have to be the MASS-ID I used when creating the "link"s. Sorry for my confusion... Ciao -- Frank Barknecht _ ______footils.org__ _ __latest track: fqdn _ http://footils.org/cms/show/38

[lp] how to get write permission as user
by Roman Haefeli 03 Mar '05

03 Mar '05

hi is it possible to use [lp] from zexy as user? if yes, how? chmod 777 /dev/lp1 won't help. to get member of the lp-group neither. sorry, if this is an obvious question for advanced linux-users. the doc says: "you might have to be root to get write-permissions on your specified port" thanx in advance roman
