RE: [PD] GEM + Logitech Quickcam = no textures
by Ian Smith-Heisters 28 Apr '04

28 Apr '04

Hmmm. As per my last message I've been trying to install a custom kernel, this has had no success so far. However, I'm not convinced pcwx is the problem. From all the documentation, pcwx simply lets one use the camera at up to 640x480, and is not required for any actual operation. Again, it is working in camstream, without pcwx. But without other possiblilities I'll keep trying to slog through the morass of kernel compilation.

Segmentation faults and compiling newest GEM on OSX
by joseph moore 28 Apr '04

28 Apr '04

Hello list, A couple questions and comments. First I noticed Sara's post regarding PDP PD crashes. While I'm not running PDP much I have been getting crashes and simular terminal messages involving segmentation faults running PD and PD + GEM. I'm on OSX Panther/G4 processor. I'll post the specific terminal message next time it happens. Anyway, just a heads up on that. Secondly, regarding compiling the newest version of GEM for OSX, could someone post a simple how-to? I'm really inexperienced compiling(it took me a week to get PDP working previous to the new installer even with the clear how-to written by Sara) so help would be greatly appreciated. Thanks all, Joe _________________________________________________________________ Watch LIVE baseball games on your computer with MLB.TV, included with MSN Premium! http://join.msn.com/?page=features/mlb&pgmarket=en-us/go/onm00200439ave/dir…

Python file dialogs + PD
by joseph moore 28 Apr '04

28 Apr '04

I would like to use the built in file dialogs from the EasyDialogs module in python in PD. Unforturnately a bug on OSX won't allow one to use the Window Manager unless the application you are in was started using a fully qualified path so to use the python file dialogs in something like the terminal you must use pythonw. Is there any trick to getting around this barrier using the py object with pd? It would make my program much much cleaner.

Hi list, PDP keeps crashing.. I'm running in under OSX; - i know that that isn't the preferable system - but i would like to get it working anyway. These are the messages that i get. I'm running it as root#. pd_gui: pd process exited /Applications/Pd.command: line 1: 603 Segmentation fault /usr/local/bin/pd -rt -path /usr/local/lib/pd/extra:/usr/local/lib/pd/pdp_pidip_osx/abstractions -lib /usr/local/lib/pd/pdp_pidip_osx/pdp -lib zexy:bonk~:choice:expr~:fexpr~:fiddle~:lrshift~:loop~ socket receive error: Connection reset by peer (54) /Applications/Pd.command: line 1: 593 Segmentation fault /usr/local/bin/pd -rt -path /usr/local/lib/pd/extra:/usr/local/lib/pd/pdp_pidip_osx/abstractions -lib /usr/local/lib/pd/pdp_pidip_osx/pdp -lib zexy:bonk~:choice:expr~:fexpr~:fiddle~:lrshift~:loop~ Another thing: if pd / pdp is started my terminal keeps adding empty lines. Any advice is welcome. thanx, sara

pix_info output for each frame: width: 160 height: 120 bytes/px: 4 color-space: 6408 I may have done the [pix_pix2sig~]-[pix_sig2pix~] trick wrong. I just tried putting those two in the gemlist between [pix_texture] and [cube], so (verbose) it looked like this: [gemhead]-[rotateXYZ]-[pix_video]-[pix_texture]-[pix_pix2sig~]-[pix_sig2pix~]-[cube] I'm not sure if that's correct. But then I tried putting them upstream of pix_info ([gemhead]-[rotateXYZ]-[pix_video]-[pix_texture]-[pix_pix2sig~]-[pix_sig2pix~]-[pix_info]-[cube]) and pix_info was outputting the same data as it did without pix2sig/sig2pix, so maybe I did do it right. I tried the cam in Gem for windows xp pro and it works like a dream (I think that was Gem 0.888-pre1 also). For what it's worth, my Gem version is from apt-get and states itself thus: ver: 0.888-pre1 compiled: Mar 16 2004 Thanks, -ISH > -------- Original Message -------- > Subject: Re: [PD] GEM + Logitech Quickcam = no textures > From: "IOhannes m zmoelnig" <zmoelnig(a)iem.at> > Date: Tue, April 27, 2004 7:16 am > To: "Martin Peach" <martinrp(a)vax2.concordia.ca> > Cc: "Ian Smith-Heisters" <heisters(a)0x09.com>, pd-list(a)iem.at > > Martin Peach wrote: > > It may be that your texture is not a power of two - try 127x127 or > 64x64. > > Martin > > > > in recent versions of Gem the texture-size doesn't need to be power of > 2 > any more (when using [pix_texture]) > for older versions of Gem [pix_texture2] (which is now an alias for > [pix_texture]) did the job for non-power-of-2 images. > > btw, 127x127 is non-power-of-2 too ;-) > > unfortunately i don't know where the problem is (esp. when the > [pix_pix2sig~]+[pix_sig2pix~] trick doesn't work either) > > what does [pix_info] say ? > > > mfg.a.sdr > IOhannes > > > _______________________________________________ > PD-list mailing list > PD-list(a)iem.at > http://iem.at/cgi-bin/mailman/listinfo/pd-list

Help! : No MIDI in Pd 0.37-1 with RedHat 9.0
by Vincent.Goudard＠ircam.fr 27 Apr '04

27 Apr '04

Hi all i was using MIDI keyboard to control Pd via the parallel/Joystick port, and it was working fine, when I was on Pd 0.37-0 / RedHat 8.0. I just updraded to RedHat9.0 and the last version of Pd 0.37-1 (th CCRMA package) and I have no MIDI input anymore... "None" appear in the MIDI setting panel. I don't know if it's due to RH or Pd, and could not find any mention to it in the list. If someone has any idea, please help!!!! Thanks vincent

RE: [PD] Netserver + UDP

That was my first attempt but unfortunately it doesn't work : - Most browsers' Java VMs don't allow untrusted applets to learn it's IP address for security reasons. - Even if the applet could send the client machine's IP, if that machine belongs to a network that uses private Ips (i.e., is behind a firewall/NAT machine) it would be useless... So what I really need is to learn the address from the point of view of the destination (PD). [netserver] does the job but only for TCP connections but UDP is more suited in my case. > >On Apr 27, 2004, at 13:58, Jorge Cardoso wrote: > >> Hi all, >> >> Is there an object like [netserver] that prints the client's IP >> address, but >> that is able to receive UDP connections? >> >> I'm trying to connect an applet to PD using netreceive but since I >> need to send data >> back to the applet I must know it's IP... >>
