is PD working well with windows vista?
by Ramirez Hugo Francisco 14 May '07

14 May '07

Dear PD fellows. I haven´t write in a long time. Because my laptop is no longer with me. I want to buy a new machine, and most of them bring windows vista. unluckily. I need that OS because of work (unfournately) , but i need to play some time to time with the beloved PD. So is possible to install it inside widows vista and the many version that comes with (home, home pro, businness, bla bla) Best regards hugo ramírez. PS: could you reply to cotetrix(a)gmail.com or put me inside the mailing list with that e-mail adress

PDP fails to load
by Joseph Barrows 14 May '07

14 May '07

Hi, I'm having trouble with PDP "/usr/lib/pd/extra/pdp.pd_linux: /usr/lib/pd/extra/pdp.pd_linux: undefined symbol: pdp_metro_setup pdp: can't load library" everythime. I'm using fedora core 6, freshly "yum install pd" and "yum install pd-*" from planetccrma repositories give pd 0.39.2 and am impressive list of pd-* things installed (some of which don't load either) are things getting in the wrong directories? i did previously have a combination on yum and manually installed pd's (trying to be all bleeding edge ... might stick to yummy stuff now) -- Joseph Barrows live video performance; web site design; new media artist jjbarrows.artwww.net jjbarrows(a)artwww.net

mp3cast~ low latency
by Richard Lewis 14 May '07

14 May '07

Hello PD-list, I'm still working on my mp3cast~ project :-) The final problem (I hope) is that I experience quite considerable latency on the client-side of around 10-12 seconds. The application is supposed to be real-time so this latency is quite a problem. A colleague suggested that it could be Icecast using a fixed size buffer. I had a look through the Icecast source code but couldn't find anything hopeful. So I put a message on the Icecast forum and was told to try reducing the burst-on-connect size to 0. I did this and it didn't seem make any difference. Of course, buffering could be the problem, but there are four places where buffering could occur: 1) in the client media streamer; 2) in the streaming server output; 3) in the streaming server source/input; and 4) in the source encoding (in this case, mp3cast~). I've made some attempts at checking cases 2 and 3. 4 is problematic in that I can't control what a user's client does. (I can provide documentation, though). So I'm trying to check case 4. Google returns four or five hits for "mp3cast~ buffering", one of which is one my previous posts to this list! Does anyone know how mp3cast~ buffering is controlled and if it is configurable either by a setting or source code hack?

pix_multiblob cpu usage
by nosehair911＠bellsouth.net 14 May '07

14 May '07

I made a 400x300 motion JPEG-a movie 15 fps with 5 solid blue circles moving on a black background to test pix_mutiblob. I open it up with pix_film, flip it with pix_flip and send it to pix_multiblob. I suddenly notices PD getting very, very slow. When I look at the cpu usage in activity monitor (if you can believe activity monitor) I get 100-104% cpu usage. I cant do anything else in PD because PD gets so slow. I am using a dual 2Ghz G5 with ATI Radeon 9800 XT and 3GB of internal memory. Is this normal? What can I do to lower cpu usage? What else can I use within Gem to get the same results? I eventually want to be able to track 20-30 objects but It looks like it would be imposible at this rate. Thanks, Alain

Re: [PD] pix_multiblob cpu usage
by nosehair911＠bellsouth.net 14 May '07

14 May '07

Can anyone running a linux and win32 box try to run this example and see if it completely drains you of CPU. I have tried it with 3 macs and I can't seem to do much more in PD. Also does anyone know of a less cpu intensive way to track objects in PD using a mac like pix_multiblob does. I would like to track at least 20 objects. My project is dead unless I figure out a better way.

where to browse GEM bugs?
by Matteo.sistisette 14 May '07

14 May '07

Hi list, I\'m using GEM in Windows and it is crashing a lot while just doing the most trivial things. Before I try to isolate and report any bug, I thought I would have a look at the bug tracker and see if it is something already known (and if there is some workaround). So I went to the pure-data bug tracker at Sourceforge, I selected the category \"GEM\" with no keyword, and there\'s ONLY ONE BUG in the database within the category GEM (\"pix_movie only play solid colors\"). Is there another bugtracker specific to GEM, or another place where one can find information about known bugs, and report new ones?

GEM part_size
by yp_ 14 May '07

14 May '07

Dear list, I've been playing around with possibilities of GEM particles, and don't seem to understand the function of the object [part_size]. Or more exact: I can't manage to create a patch where this object takes any effect on the output. Could anyone help me out with this? I've searched the archive but didn't find anything closely related to an explanation of this object. The reference doesn't help me out either, but maybe I'm not using it in the right sequence of particle-objects. The [part_info] object does output 10 for size when I input 10 in [part_size] but the gemwindow keeps showing the same results as with an input of 1. I'm using OSX 10.4.9 Same (non-)results on Intel as on other macs I'm searching for a way to easily get results in between the 1pixel lines and the filled surfaces when working with particles, to open a graphical playfield (like the blurry screensavers on macs). I had a feeling part_size could help me out here, but maybe this object only affects the gravity, like 'mass' in pmpd? Best regards, Yorick

It's not > possible to reblock parts of the patch that contain these objects. I thought of that.. I created a very simple patch with everything block~ 1, nothing connected... As soon as the program opens it gives errors. It seems to me that throw~/catch~ at blocksizes other than 64 acts weirdly, which is an awful shame because it was almost perfect for my purposes K
