OSC over multicast
by ben＠ekran.org 11 Nov '03

11 Nov '03

Hey all, Last year I thought about writing a multicast communication object for PD. Then I did not have enough time and it never got off the ground. Now I have the need to communicate between PD and MAX over multcast, and I think OSC is the way to go... I *seem* to be able to specify a multicast region to send to (port IP combination) which is not a host but a virtual multcast group. (I guess this part is the same between UDP and multicast? What is missing is being able to route data from multicast, ie being able to specify not a port [because the connection is not to the host] but a port/IP of a multicast group... There may be video and audio data packets flying around that area, but I think the OSC naming will ignore that data any only route OSC packets it sees in the multicast group... Each client in a multicast region has a "SRCID" that defines what data comes from whom. It would be REALLY nice if this could be integrated into the naming scheme so that one could route data OSC based on who sent it... I suppose this would be easy enough by prepending a unique name for each client before sending out the data? It would be also nice to be able to create a list of clients in the region by the OSC name... Ok, anyone interested? (come on out you AG people!) Thanks Ben

compilation broken @ FreeBSD
by Kenneth Peiruza 06 Nov '03

06 Nov '03

Hi all, I'm quite new @ PD, moreover at this list, so, don't hesitate if I'm completly wrong :) I've been trying to compile new versions of PD into my FreeBSD 5.1. At this time, compilation breaks everywhere. Some errors found: - ./configure generates a "makefile" despite "Makefile". In some pd distributions exist a Makefile file by default, so "make" uses it despite "makefile". - After ./configure, I do make ( Actually "gmake" gnu-make ): ---------------------------------------- cc -DPD -DUNIX -Wall -W -Wstrict-prototypes -Werror -Wno-unused -Wno-parentheses -Wno-switch -DINSTALL_PREFIX=\"/usr/local\" -I. -c -o ../obj/s_main.o s_main.c s_main.c:308: `API_DEFSTRING' undeclared here (not in a function) s_main.c:308: initializer element is not constant s_main.c:308: (near initialization for `usagemessage[17]') gmake: *** [s_main.o] Error 1 ---------------------------------------- This is due to NO DEFAULTS at s_stuff.h I change it to make it compile. I dunno much about sound capabilities at freebsd, but it's certainly true that it supports OSS, so i add these lines at s_stuff: #define API_DEFAULT API_OSS #define API_DEFSTRING "OSS" Now it compiles a bit more :) But, of course, it breaks down at pthreads.... : -------------------------------------------- cd ../obj; cc -o ../bin/pd g_canvas.o g_graph.o g_text.o g_rtext.o g_array.o g_template.o g_io.o g_scalar.o g_traversal.o g_guiconnect.o g_readwrite.o g_editor.o g_all_guis.o g_bang.o g_hdial.o g_hslider.o g_mycanvas.o g_numbox.o g_toggle.o g_vdial.o g_vslider.o g_vumeter.o m_pd.o m_class.o m_obj.o m_atom.o m_memory.o m_binbuf.o m_conf.o m_glob.o m_sched.o s_main.o s_inter.o s_file.o s_print.o s_loader.o s_path.o s_entry.o s_audio.o s_midi.o d_ugen.o d_ctl.o d_arithmetic.o d_osc.o d_filter.o d_dac.o d_misc.o d_math.o d_fft.o d_mayer_fft.o d_fftroutine.o d_array.o d_global.o d_delay.o d_resample.o x_arithmetic.o x_connective.o x_interface.o x_midi.o x_misc.o x_time.o x_acoustics.o x_net.o x_qlist.o x_gui.o d_soundfile.o \ -lm s_inter.o: In function `sys_bail': s_inter.o(.text+0x1313): undefined reference to `sys_close_midi' s_midi.o: In function `sys_putnext': s_midi.o(.text+0x1e7): undefined reference to `sys_putmidibyte' s_midi.o(.text+0x224): undefined reference to `sys_putmidimess' s_midi.o: In function `sys_pollmidiqueue': s_midi.o(.text+0xa03): undefined reference to `sys_poll_midi' s_midi.o: In function `sys_open_midi': s_midi.o(.text+0xb1b): undefined reference to `sys_do_open_midi' s_midi.o: In function `sys_listmididevs': s_midi.o(.text+0xbb9): undefined reference to `midi_getdevs' s_midi.o: In function `glob_midi_properties': s_midi.o(.text+0xd05): undefined reference to `midi_getdevs' s_midi.o: In function `glob_midi_dialog': s_midi.o(.text+0x1222): undefined reference to `sys_close_midi' x_midi.o: In function `midiout_float': x_midi.o(.text+0x16a6): undefined reference to `sys_putmidibyte' d_soundfile.o: In function `readsf_new': d_soundfile.o(.text+0x3897): undefined reference to `pthread_create' d_soundfile.o: In function `readsf_free': d_soundfile.o(.text+0x4155): undefined reference to `pthread_join' d_soundfile.o: In function `writesf_new': d_soundfile.o(.text+0x4b5b): undefined reference to `pthread_create' d_soundfile.o: In function `writesf_free': d_soundfile.o(.text+0x5235): undefined reference to `pthread_join' gmake: *** [../bin/pd] Error 1 --------------------------------- Any ideas?

unsubscribing from the CVS list
by IOhannes zmoelnig 06 Nov '03

06 Nov '03

hi list. i'd like to express my sorry feelings about what's happened with the CVS-list. subscribing all pd-dev's to another list without really asking them, is what i normally would call *spam*. unfortunately i have done so, and i really regret it now. (i regret it for some time now, but i think i haven't yet said so) anyone, who is not interested in getting CVS-mails should unsubscribe him/herself from the list, following the instructions at http://iem.at/cgi-bin/mailman/listinfo/pd-cvs to get your password, just fill in your email-address in the last field (Edit options). then click on "Email My Password to Me" and wait... after you have received the password, you can unsubscribe yourself sorry again for mis-using the pd-dev'subscribers information. mfg.asd.r IOhannes

New to PD.
by fervid gnat 05 Nov '03

05 Nov '03

I'm new to PD, therefore I am not sure if this is the appropriate place to ask questions. However I thought I would give it a try. I'm wondering if anyone could point me in the right direction. I'm looking for an example of a patch that would allow me to composite (chroma key) live video. If anyone has any tips I would be very grateful. thanks pdmailing(a)yahoo.ca ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca

PiDiP Segementation
by ben＠ekran.org 02 Nov '03

02 Nov '03

I finally got PiDiP compiled. It took 5 hours today. The real problem was SUSE Rpm's not having the right versions of software. (for example aalib 1.2 does not work, but aalib1.4 (latest release candidate for today) does). Also Lame and vorbis don't work very well together. What exact version of everything do I need to be using? I had to comment out an include to modes.h in Lame because it was not part of vorbis (or anything else as far as I can tell). First I was getting a bunch of unresolved symbols in -lmp3lame Eventually I had to disable vorbis support in lame even to get lame to compile. PiDiP seemed happy about that at the configure stage. I got it compiled and now I segfault on load: Program received signal SIGSEGV, Segmentation fault.
