hi. this list is set-up in a way, that the "reply-to" field is not re-written to the list's adress. this means, that when you simply click on "reply", only the original sender will get your answer. please "Reply to all" or use your mail-clients special mailing-list handling to answer posts to the list. (to have a discussion on why this is so, please search the pd-list and pd-ot archives and read http://puredata.info/community/lists/netiquette/) people seasrching the archives will be thankful...

Re: [PD] ASCSEQ
by timon botez 27 Jan '06

Do you know if theres a limit to how much data the ascseq can hold? Length of symbols? I need the ascseq to drip at 200 ms. (needs the time too spit out the font metrics. not ideal I know, and Ill be improving that for the future, but I have a little gig for thursday, so this is an interim fix) The proposed method look risky. l2s is currently working well...

PD browser plug-in
by Jan Meinema 26 Jan '06

26 Jan '06

Hi, http://www.iua.upf.edu/~malonso/pdplugin/ I just found out about this (a day after handing my MA on interactive audio), I am amazed that I did not find out about this as I always read the mailings, ah well. Just wanted to let anyone else know that is interested in 'Sonifying' the web and raising the standards for sound design on the web. Just need a mac browser version now. Jan Jan Meinema

compiling Pd for microcontrollers
by Hans-Christoph Steiner 26 Jan '06

26 Jan '06

So I am working with the Arduino and the Wiring programming environment, and it got me thinking: what about a patcher language for microcontrollers? It could be done like Pocket Gamelan, the Pd->J2ME compiler. http://www.uow.edu.au/~mh675/personal/pd2j2me.htm There would be a subset of Pd which would be allowed for microcontrollers. This would then be compiled to a microcontroller firmware and uploaded to the chip. Maybe its time to think of a more general approach to compiling Pd patches. It would be quite nice to be able to program mobile phones and microcontrollers in Pd. .hc ________________________________________________________________________ ____ "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore

Why isn't this working
by Jonathan Goodwin 26 Jan '06

26 Jan '06

I've attached my ongoing dance-mat video triggering patch. After the discussions earlier in the week regarding pausing GEM videos, I've tried to implement the method recommended to me using a counter: I.e: [Metro 40] 25fps =40ms per frame | | [counter 0 x] where x is vid length | | Right inlet of [pix_movie] Am I not right in thinking that the far right inlet of pix_movie should control which frame the movie begins rendering on? Because this doesn't seem to be having an effect on the movies, and they all start from the beginning each time they are played?

PDP updates
by doelie＠zzz.kotnet.org 26 Jan '06

26 Jan '06

hi all, i'm working on a bug fix release for PDP. currently there's only a darcs archive. there will probably be a release around mid februari, for the first Huddersfield workshop. this means that PDP and Packet Forth are officially forked, alas.. no more denial :) if there's some small annoyance or bug you'd like to see fixed, send an email to pdp(a)zzz.kotnet.org for more info, see: http://zwizwa.goto10.org/zwikizwaki.php?page=PureDataPacket most important changes since 0.12.4 are pdp_del, pdp_rawin/out and i420 bitmaps. there's also the doc/misc/rawout.txt file explaining how to use rawout and pdp_metro to dump raw audio/video to the harddisk and convert it offline using mencoder/ffmpeg. this seems to be the simplest way to save CPU power when doing live video recording. one thing several people seem to miss in PDP is more input video codecs. i'm not going to add support for it, but it is possible to use pdp_rawin in combination with my pf-rawvideo.* scripts. these are little wrappers around ffmpeg and mencoder to produce i420 streams on stdout. they can be found here: http://zwizwa.goto10.org/darcs/libpf/bin/ tom

pidip and video optimization
by Rolland G. B. 26 Jan '06

26 Jan '06

hi list, wandering what would be the best solution for playing two full screen samples with [pdp_yqt] ... [pdp_xv]. I tried to run X with different modes - "800x600" "640x480" with transcoded videosamples to according sizes, that i do not need to use [pdp_zoom] ... so far is not much better than in 1024x768, videos are not smooth and sound has clicks. problem is that i must use also [pdp_rotate 90] and [pdp_zoom 1.36] to rotate and resize the videos to 3:4 instead of 4:3 (perhaps there is a better way ?) ... four channel sound output and controll input from gamepad with [hid]. this is on P4 2.5Ghz and nVidia GeForce FX 5200. samples are mov with jpeg Codec: 'Photo - JPEG' best R.G.B. --

Hi, Hans, I got this error when startup Pd-0.38.4-extended-RC7 (OSX 10.4.4): /Users/matema/Desktop/Pd-0.38.4-extended-RC7.app/Contents/Resources/ Scripts/../extra/pdp.pd_darwin: dlopen(/Users/matema/Desktop/ Pd-0.38.4-extended-RC7.app/Contents/Resources/Scripts/../extra/ pdp.pd_darwin, 10): Symbol not found: _gluOrtho2D Referenced from: /Users/matema/Desktop/Pd-0.38.4-extended-RC7.app/ Contents/Resources/Scripts/../extra/pdp.pd_darwin Expected in: /usr/X11R6/lib/libGL.1.dylib so I changed the pdp.pd_dawin from RC7 to pdp.pd_darwin RC5 and the error didn't appear more...
