Re: [PD] pix_record problem

Hi, could you isolate the problem in a simple patch and post it to the list? This way we can test it. cheers, M Hi all, > > > > I'm trying to record a sequence using pix_record , the patch deals with a > lot of movement in the space of the GEM window,I'm using 5 pix-film objects, > > but all that I get are the images, not moving in space, all the > translateXYZ objects seems to be useless. > > Is there a way to get all that movement of the gem window using pix_record? > > > > Best Wishes > > _______________________________________________________________________________________________________________________________________________ > > > -- Marco Donnarumma aka TheSAD Independent New Media Arts Professional, Performer, Teacher Ongoing MSc by Research, University of Edinburgh, UK PORTFOLIO: http://marcodonnarumma.com LAB: http://www.thesaddj.com | http://cntrl.sourceforge.net | http://www.flxer.net EVENT: http://www.liveperformersmeeting.net

pd-extended source
by ailo 25 Sep '10

25 Sep '10

I did a succesful build of pd-extended-rc6 on Ubuntu Maverick amd64. Pidip did not compile, so I left it out . Still working on the build. I believe I got the source by doing the auto-build process: rsync -av --delete rsync://128.238.56.50/distros/pd-extended/ pd-extended/ ./pd-extended/scripts/auto-build/pd-extended-auto-builder.sh -- I tried building from this source as well, once it was released: http://downloads.sourceforge.net/pure-data/Pd-0.42.5-extended.tar.gz Build failed already at bonk~. Is pd (not pd-extended) not updated in this source? What is different about this source?

Click Tracker software
by João Pais 25 Sep '10

25 Sep '10

Dear Sir, I would like to present you the Click Tracker software. The Click Tracker is a program designed for composers, conductors and instrumentalists that work with modern music. The main goal of the software is to prepare a click track of any score, no matter of how complex it is. This software can be used either by conductors in concert, by musicians for practise purposes, by composers while composing - or just to produce and record a click track to be played back at a later point. The CLick Tracker can be downloaded freely in http://puredata.info/Members/jmmmp/click-tracker (Paypal donations are possible). It runs on Pure Data Extended (also a free program) in any operative system, and installation instructions for both programs are in the same page. I hope that you find this software useful. I would like to hear back of any suggestions, critiques or simple feedback. Best regards, JoÃ£o Pais -- Friedenstr. 58 10249 Berlin (Deutschland) Tel +49 30 42020091 | Mob +49 162 6843570 Studio +49 30 69509190 jmmmpais(a)googlemail.com | skype: jmmmpjmmmp

noaudio question
by Matteo Sisti Sette 24 Sep '10

24 Sep '10

Hi, I know running with -noaudio is NOT exactly the same as running normally and keeping dsp turned off. However, when running a "gem patch" with nothing audio-related in it, I expected that the performance would be the same in the two cases (NOT the same as running with dsp turned on, of course). However, I am under the impression that -noaudio gives me better performance, though I'm not sure. Is that possible? thanks m.

Re: [PD] pidip pdp_capture not working
by ydegoyon＠free.fr 24 Sep '10

ola, pdp_capture was too slow, it is now abandonned, you can use webcamstudio to capture your screen and send it to video loopback device ( usually /dev/video1 ) that you can read it with pdp_v4l, that's the replacement.. saludos, sevy bernard delcourt wrote: > hello, > I do not know if I am addressing the box to the right letter, Exuse me > if I'm wrong and my English is translated by Google. > After much research I remain unanswered: pdp_capture does not work, > I'm on Ubuntu (hardy or intrepid) with Pd version 0.42.5-extended-20100601 > In my libraries pdp pidip and everything works well in general.

Newbie question about global tempo, metro
by jm jones 24 Sep '10

24 Sep '10

Hi, Im learning pd, making my first patch. I'm reading Johannes Kreidler book "loadbang", but I want to learn some things right now : ) I make a BPM metro (bpm number / 60000 to metro right inlet), but I dont know how to connect that to other sections in the patch. For example, I have an abstraction with a sequence of frequencies and a metro. I want that subpatch/abstraction to be "launched" in time according to the global bpm metro, but maintaining the value of his own metro. Thanks in advance. -- JM Jones

To: Jack <jack(a)rybn.org> Hey Jack, Thanks a lot for that. It's still crashing when I open the second avi.:( I used different abstractions (correctly or not) because I'm using three [gemhead] 1-3 to play the videos. I thought that is the way no? So each abstractions contains a different gemhead. Even though I have given each abstraction a different name, they all have the same canvas i.d.? Very confusing...

(GEM) mjpeg decoding performance question
by Matteo Sisti Sette 24 Sep '10

24 Sep '10

Hi, I'm trying to find the codec with best performance to use with gem in Ubuntu. Up to now the best I've found is MJPEG, but the funny thing is that if I code the file myself with MJPEG using Avidemux, I get much better performance than with a file also coded with MJPEG that I was given. What can it be due to? When I code the file with MJPEG the only parameter I can change is "quality" Does it depend entirely on the quality setting, or is it possible that different implementations of the encoder encode in such a way that it is then more or less expensive for the decoder to decode? thanks m.
