performance-problem with [print] on pd-0.39 on win
by Roman Haefeli 05 Oct '05

05 Oct '05

hi miller, hi list printing a lot of text eats my cpu on win and pd-0.39. i didn't test on pd-0.38, though, but on pd-0.37 i didn't get a specially high cpu-load, since (i'm only assuming) the output is printed to the shell and not to a tk/tcl-gui. printing the line [eins zwei drei vier fuenf sechs sieben acht neun zehn( 40 times a second eats 95% of cpu (win, pentium M @ 600MHz). same test on linux: no remarkable rising of the cpu-load. sorry to say that, but this is one reason for me to wish back the old 'print-to-shell'-style. another is, that the 'new' pd-window is very big and the fontsize is big, too (btw: is it possible to set the fontsize of the pd-window?) excuse me, if there are some important advantages, that i don't see yet. cheers roman ___________________________________________________________ Gesendet von Yahoo!

Another Gem performance issue
by Christian Veit 05 Oct '05

05 Oct '05

Hello list, I have performance problems in Gem while playing an mpeg and connecting to my camera with firewire. The problem is when i start rendering the pd process is on nearly 100% and every 5 to 10 seconds a new frame is displayed. Also the mouse and keyboard events are responding after some seconds. Xorg is using nearly nothing of cpu time. In glxgears i got a framerate about 4000fps... Direct Rendering is enabled... My cpu should be fast enough (1,7GHz)... I've tried gem version 0.9 and the newest from cvs... LG Christian -- Lust, ein paar Euro nebenbei zu verdienen? Ohne Kosten, ohne Risiko!

ann -- overview and helppatch
by Gerda Strobl 05 Oct '05

05 Oct '05

Hi list, I want to have a look at the "ann"-objects. Is there now some help-ann.pd file? Is there an overview of what objects are existing (ann_som, ann_mlp....)? And Johannes, in some posting in 2002 you referred to some dokumentation on your web(umlaeute.mur.at/nos)-was this doc of the installation or doc of the object? Thanx. Gerda <http://umlaeute.mur.at/nos>

various pix objects
by demidelirium 05 Oct '05

05 Oct '05

hi list, a little while back i was having problems getting pix_kaleidoscope objects to be created. (winxp, pd is pd-extended 0.37 from the executable installer) just reinstalled absolutely everything on my computer. same thing, except i only just realized it's the same for various other pix_objects, such as pix_motionblur, pix_levels etc. (is the common denominator that these are all freeframe ports?) all produce a "... couldn't create" message does anyone have any suggestions? should i try a manual build of either pd, or gem? anybody know a working version for windows that has these objects thnx d

by dominic 05 Oct '05

05 Oct '05

Hi there, I'm having a spot of bother with Gem, I just cant get it to load in pd I just upgraded to the demudi testing repo and installed pd-pdp-caedes (currently getting segfaults in 3dp) and now I get the following error /usr/lib/pd/extra/Gem.pd_linux: /usr/lib/pd/extra/Gem.pd_linux: undefined symbol: avcodec_pix_fmt_to_codec_tag Gem: can't load library I have libavcodeccvs 3:20050427-02(testing) installed. I noticed I had libavcodec1 also installed so I removed that. Any clues? need any more info? thanks dominic

deleting data structures
by david golightly 05 Oct '05

05 Oct '05

Hello list, I'm trying to teach myself how to use the data structure feature in 0.38-3 - it seems this feature is still very much under development - is there a way to dynamically delete structures, to "un-append" them from a list? I want data structures to appear alongside sound-events, then expire as the events pass on. BTW, I find that the inconsistent terminology used in the documentation to describe data structures makes it quite baffling to the neophyte, as terms like "list" (a list of scalars) confuse with a normal pd list of atoms (floats, symbols etc.) and they're treated quite differently. Also, the documentation hasn't been updated to reflect changes in the features (templates, obsolete by 0.38, are still referred to in the docs, for instance) - I would be more than willing to work with whomever has taken on such things to see to it that the documentation gets proofread and checked for consistency with each release - I've had no problem learning most of the rest of PD but these data structures are something different altogether. Or does anyone else out there know of any better/revised documentation? Do many people find the data structures useful? I think the idea has a lot of potential but hasn't yet been worked out in all its details. I'm interested in seeing this happen. Thanks, David

Re: determine local IP address
by scotgl＠comcast.net 04 Oct '05

http://www.audiomulch.com/~rossb/code/oscgroups/ is the pointer to Ross Bencina's page for his open source solution for getting OSC messages in a group withoout needing to type in a bunch of ip addresses. you basically just need to know the IP address of the server and the agreed upon send and recieve ports, usually high and out of the way of all the others, a username, groupname and password. Then you just use localhost and the server provides the other subscribers ip to the client. We have been using it for about a year now and it is very robust. you can run the server locally or as we did where we used an OSC server in Barcelona from a gig in Rotterdam. In another case we used a server running in Valencia, Calif. was used for a performance in Berlin. Ther ewere no issues of latency since it is just polling to provide subscriber ip numbers. Let me know if anyone is trying to do any network pieces. If I have time I would love to be involved. Scot -- Your name is Hamlet.
