Webcam&hardware requirements
by Rune Lain Knudsen 31 Aug '05

31 Aug '05

I hope this is not too OT, but I'm working on a project where PD/GEM is going to be used for interpretation of a tree's movement caused by wind. Basically a camera will be used to record a tree, this will be made into a moviefile that will be uploaded to a website periodically. The movement from the tree will be the basis for triggering a database containing words and phrases. Does anyone have any recommendations regarding a camera/webcam that doesn't cost too much and which is capable of recording 30fps with a fairly good resolution? It also needs a zoom lens as the tree will be a bit far away from the camera. I was thinking about using a mac mini to record, interpret and upload; would the standard(1.4Ghz/512MB/80GB) be enough for this? Thanks in advance, Rune _______________________________________________________________ How "hot" is the hottest creature on Earth? postmaster.co.uk http://www.postmaster.co.uk/cgi-bin/meme/quiz.pl?id=6

asio problems under windows
by Maik Hester 31 Aug '05

31 Aug '05

Dear Members of the PD Mailinglist, where does PD store the binaries in windoze (XP)? Some time ago I entered the line "c:/programme/pd/bin/asiolib.lib" in the binaries menu and added the startup flag "-r 44100". When I delete the commands and reboot the computer, they return. Since any attempt to delete these commands fails I deleted the complete pd installation and reinstalled it, but the entries are still there. I checked the windoze registry, but the entries were not there, too. Second, I want to use PD with my Hercules 16/12 Firewire Interface, but PD only recognises two channels. What can I do? Every time I run PD it starts with the error message "separate audio device choice not supported\; using sequential devices. c:/programme/pd/bin/asiolib.lib: can't load library" and fails to initialize the interface correctly. Thanks for your help, Maik.

Hi all Wondering if anybody has advice re running Pd on OS X 10.4. I'm on 10.3.9 right now, and I have 10.4 sitting here, but I've been warned off running audio programs until 10.4 gets better. I'm using Hans-Christoph's 0.38 installer and trying out the 0.39 releases. Thanks for any info. cheers dafydd

$1 routing
by Chuckk Hubbard 30 Aug '05

30 Aug '05

I have no idea how you could search for an issue like this in the archives... I pack a float and two symbols, and route the symbols according to the float. The first symbol disappears. I tried inserting [symbol] before each $ message, and the second symbol disappears. What am I missing? -Chuckk -- "It is not when truth is dirty, but when it is shallow, that the lover of knowledge is reluctant to step into its waters." -Friedrich Nietzsche, "Thus Spoke Zarathustra"

Vst~ and Waves 5.0 problem?
by saint 30 Aug '05

30 Aug '05

Hi, Thanks very much Thomas for the vst~ .dll from your website... <http://grrrr.org/ext/beta> ...I was wondering is there a way to get waveshell-VST 5.0 to work? I got a subplug to work once but every time since the the subplug sounds okay but when I bring up its gui I only get a grey box! Then pd crashes. Any thoughts anyone? (I have waveshell-VST 5.0.dll in my pd/extra folder) Thanks a million, John. ___________________________________________________________ Yahoo!

v4l issues in Gem & PDP WAS Re: [GEM-dev] pix_video under linux
by B. Bogart 30 Aug '05

Hey all, I thought what the heck, lets see if I can see my tuner cards in pdp_v4l. So I get the same freeze as I got in Gem: (gdb) bt #0 0xffffe410 in __kernel_vsyscall () #1 0x40128e48 in pthread_join () from /lib/tls/i686/cmov/libpthread.so.0 #2 0x42a86440 in pdp_sdl_setup () from /usr/lib/pd/extra/pdp.pd_linux so my pthreads are killing me... Help, What do I do? debian sarge w/ demudi and unstable packages. (pthread is stable/sarge) 2.6.8 32bit kernel on an AMD64. Thanks in advance, I need to fix this for an installation in 1 month.

Re: [Fwd: Re: [PD] teabox...any users drivers]

acracia(a)riseup.net schrieb: > what about OSC through localhost? if you're sending just plain numbers it > doesn't load your system as much as usb midi... at least in Linux We were using a Toaster from LaKitchen, which is well aimed at that. I think its even more pricey then a teabox (can't confirm at the moment). We had problems with certain switches though, but that was related to the switches. Otherwise it worked, but as the load of data was way higher than Midi could handle, the overall load was higher than comparable usb midi load, especially because our set was using simple sliders, which would not require any data to be sent as long the slider wasn't touched. The Toaster was sending a stream of data all the time, which is fine if working with sensors, which move and change all the time anyway. For our set a simple CV-to-Midi was preferable. Shortly: it depends very much on the application and the device which is sending the data. Could be better or worse than Midi. (This applies to all operating systems, not just Linux) Stefan

help menu
by rainer kohlberger 29 Aug '05

hi! questions about the help menu: - is there an easy way, to create your own help-menu entries, without compiling anything? ..like there is a really long list in the extended pd-version by hans. - in pd 0.39 [on os x 10.4], there is only 'html...' and 'browser...' left. the browser window takes about 5sec to open, the second time i try to open it, nothing happens. anyone has this behaviour, too? could it be related to os x tiger? thanks, rainer.
