there was something missing for connecting all osc~ instances, it's fixed in attached one ----- Mail Original ----- De: "colet patrice" <colet.patrice(a)free.fr> À: "Pierre Massat" <pimassat(a)gmail.com> Cc: "pd-list" <pd-list(a)iem.at> Envoyé: Jeudi 4 Mars 2010 06h37:06 GMT +01:00 Amsterdam / Berlin / Berne / Rome / Stockholm / Vienne Objet: Re: [PD] A better pitch shifter?

gem and gmerlin on Ubuntu
by Martin Eckart 03 Mar '10

03 Mar '10

I've been struggling for the past few hours with ffmpeg trying to create an video file that Gem will accept that contains an alpha channel from a series of tiff images. While searching for answers I found some messages that mention that new versions of Gem are using gmerlin as an a/v decoder which should open it to many more formats. I'm currently on Ubuntu 9.10 with pd-extended version 0.42.5-extended-20091114. I probably installed it from a .deb package somewhere. Gem info: GEM: Graphics Environment for Multimedia GEM: ver: 0.93.CVS GEM: compiled: Nov 14 2009 Is gmerlin support included in that Gem version? Is it a simple matter of enabling it? Are the Gem .debs with it built in? Will I have to compile from source to get what I want? Also, I'm fully open to any suggestions on how to make alpha-channel enabled videos that Gem can read. My ffmpeg line for jpeg sequences is: ffmpeg -f image2 -vcodec copy -i sample%04d.jpg sample.avi If I try the same with alpha enabled .png files, Gem throws errors about MPNG: <AVI reader> : Stream 0 vids : MPNG (0x474e504d) 117 chunks (0.46KB) <reader> : Initialized video stream (chunk tblsz: 117, fmtsz: 40) <codec keeper> : Found 5 plugins (/usr/lib/avifile-0.7,A:22,V:32) <codec keeper> : CreateVideoDecoder(): Unknown codec 0x474e504d = "MPNG" Thanks, -martin

To pack or not to be packed that is the question ! (?)
by meino.cramer＠gmx.de 03 Mar '10

03 Mar '10

Hi, I made a [pack t b f f f f f f f f f f ] And connect ten vertical sliders to inlet 2-10 (1-based). Then I connected the outlet of the [pack] to a message box with the following contents: [wave1 sinesum $1 $2 $3 $4 $5 $6 $7 $8 $9 $10] I added a tabread4-mimic and could display the wave in an array visually. So nice so mysterious ( at least for me ;) ) Slider 1 to slider 8 are working as exspected, moving slider nine and ten results in nothing but the pure sound of silence (visually spoken...). For what I read about [pack] the inlets sequence follows the arguments or in my case inlet #2 up to #10 are exspecting float arguments, which are given by the vsliders. A [BANG] at inlet #2 send a bang into the pack. But the reason, why slider #9 and slider #10 are on holidays is not very obvious to me. The aim of all this should be a wave, which reacts on changes of each of the sliders instantly without sending an extra bang. And I want to have all slider (better: much more than ten) working. And if there is a way to normalize the result instantly I would one step nearer to eternity ;)))) I know, that there are obviously far better and total different ways to accomplish what I want to acchieve, but for the first I only want to understand, why this beast is only running on eight instead of ten legs (my be a spider therefore... ;) Thanks a lot for any help in advance!

The first slider does not need a [t b f] because it is connected to the "HOT" inlet already. When it sends a number the first inlet, the [pack] gives outlet. The others use a "bang" message so that [pack] sends output with all the numbers it has stored in the "COLD" inlets already when the "bang" goes to the "HOT" inlet. This is one of the most important concepts in Pd, so pay close attention to this! Best, Derek PS. please keep this conversation on the Pd list so others can learn too!

Did you try shifter~ (http://julovi.net/j/?page_id=7)? This is a Pd PSOLA pitch shifter I ported from Max/MSP. Developed originally by Tristan Jesen and hosted here.
