Hi A quick one: Is there an object that does the same as the change object but with symbols/text strings instead of numbers? TIA Soeren

hi, don't bother finding the reason for these errors, i've upgraded my compiler to a 3.2.4 and everything worked fine after that. best, sevy/yves ps: still no solution for the mpglib problem, maybe i should try mad ?? martin pi wrote: >i used 0.2.4 if i remember it right (am at home >now, so no pd on my 66mhz laptop) > >i also recently changed to gcc-3.0 and g++-3.0 > >anyway: building should be no problem with either >recent flext version. ill have a look in the next >days. > >martin > > > > > >On Wed, 11 Sep 2002, Yves Degoyon wrote: > >>hi, >> >>what version of flext is needed to use these externs ?? >> >>right now, they compile fine but when i try to load them, >>i've got this error : >> >>polarizer~.pd_linux: undefined symbol: >>AddXlet__10flext_baseQ310flext_base4xlet4typeiRPQ210flext_base4xlet >> >>what's actually defined in flext.a is : >> >>AddXlet__10flext_baseQ310flext_base4xlet4typeiPCcRPQ210flext_base4xlet >> >>what's wrong here ?? >> >>cheers, >> >>sevy/yves >> >> >>martin pi wrote: >> >>>hi people, >>> >>> >>>i finally managed to put some stuff online, so >>>here come: >>> >>> >>> polarizer~ >>> transverb~ >>> buffer_override~ >>> polarizer~ >>> >>> originally being vst plugins now converted >>>to pd exxternals --- bugged first versions though >>> >>> all these mangle crunch and overflow your >>>audio data radically. >>> >>> http://attacksyour.net/pi/pd >>> >>> >>> >>>--------------- and ------ >>> >>> >>> mad3~ >>> madstream~ >>> >>> integer based mp3 decoder externals for >>>pd and PDa -- mad3 is just for files while >>>madstream - lets say - tries to stream audio. >>> >>>these are really experimental and a bit hard to >>>compile (warnings and complaints). >>> >>> >>> http://attacksyour.net/pi/pd >>> >>> >>> >>>since i do not like version numbers - especially >>>those starting with 0 - these all ship as version >>>1. >>> >>> >>>have fun! >>>martin >>> >>> >>> >>> >>> martin pi >>> >>> http://attacksyour.net/pi >>> >>> johann strauss gasse 32|7 1040 vienna >>> >>> www.machfeld.net >>> >>> >>>_______________________________________________ >>>PD-announce mailing list >>>PD-announce(a)iem.kug.ac.at >>>http://iem.kug.ac.at/cgi-bin/mailman/listinfo/pd-announce >>> >>> >> > > > martin pi > > http://attacksyour.net/pi > > johann strauss gasse 32|7 1040 vienna > > www.machfeld.net > > >

Re: [PD-announce] dfx linux ports && mad mp3

Hi Yves, this looks like a gcc version mismatch. The gcc compiled objects of the various versions are not binary compatible, so you need to compile flext AND your externals with the same compiler version. sincerely, Thomas ----- Original Message ----- From: "Yves Degoyon" <ydegoyon(a)free.fr> To: "martin pi" <pi(a)attacksyour.net>; "Thomas Grill" <t.grill(a)gmx.net> Sent: Wednesday, September 11, 2002 6:04 PM Subject: Re: [PD-announce] dfx linux ports && mad mp3 > hi, > > what version of flext is needed to use these externs ?? > > right now, they compile fine but when i try to load them, > i've got this error : > > polarizer~.pd_linux: undefined symbol: > AddXlet__10flext_baseQ310flext_base4xlet4typeiRPQ210flext_base4xlet > > what's actually defined in flext.a is : > > AddXlet__10flext_baseQ310flext_base4xlet4typeiPCcRPQ210flext_base4xlet > > what's wrong here ?? > > cheers, > > sevy/yves > > > martin pi wrote: > > >hi people, > > > > > >i finally managed to put some stuff online, so > >here come: > > > > > > polarizer~ > > transverb~ > > buffer_override~ > > polarizer~ > > > > originally being vst plugins now converted > >to pd exxternals --- bugged first versions though > > > > all these mangle crunch and overflow your > >audio data radically. > > > > http://attacksyour.net/pi/pd > > > > > > > >--------------- and ------ > > > > > > mad3~ > > madstream~ > > > > integer based mp3 decoder externals for > >pd and PDa -- mad3 is just for files while > >madstream - lets say - tries to stream audio. > > > >these are really experimental and a bit hard to > >compile (warnings and complaints). > > > > > > http://attacksyour.net/pi/pd > > > > > > > >since i do not like version numbers - especially > >those starting with 0 - these all ship as version > >1. > > > > > >have fun! > >martin > > > > > > > > > > martin pi > > > > http://attacksyour.net/pi > > > > johann strauss gasse 32|7 1040 vienna > > > > www.machfeld.net > > > > > >_______________________________________________ > >PD-announce mailing list > >PD-announce(a)iem.kug.ac.at > >http://iem.kug.ac.at/cgi-bin/mailman/listinfo/pd-announce > > > > > >

writesf~ and dropouts
by Orm Finnendahl 11 Sep '02

11 Sep '02

Hi all, 1. does anybody have any experience with streaming audio input via writesf~ to the harddisk? On my laptop with RME hdsp interface and PCMCIA, audio input works very well. But if I start recording with writesf~, after a while I get dropouts. No big clicks or reported underruns, but rather subtle skips of about 0.2-0.3 seconds in the signal. Increasing the blocksize to insane amounts doesn't help the least. 2. Did anybody succeed to get input via the spdif inputs of the Hammerfall? They supposedly are on alsa inputs 17 and 18, but nothing gets in. Judging from my setup with my Mac, I somehow have to tell the Multiface to take external sync, which lights up the spdif lock led. With my linux setup that led isn't lit up which might be the reason why I don't hear anything. -- Orm

numberbox bug report
by Frank Barknecht 10 Sep '02

10 Sep '02

Hi, I can reproducably crash PD 0.35 Linux with numberboxes (nbx) in graph-on-parent abstractions. It occurs in gop-abstractions with at least two nbxes, when I do the following: 1. Type something into one of them, but don't end the typing with RETURN. 2. Type something into another nbx and end it with RETURN. ==> PD crashes. Try for yourself with the attached crashit.pd patch. Any ideas, what might be the cause? [Regarding nbx-objects: It would be nice, if they could be moved with the cursor keys like the other GUI objects.] ciao -- Frank Barknecht _ ______footils.org__

scaling pix_draw in GEM ,and GEM performance question
by Jim Ruxton 10 Sep '02

10 Sep '02

Hi, I am having trouble scaling images using pix_draw. I thought I could scale an image using scale or scaleXYZ before pix_draw but it seems like these objects have no effect. I can scale an image by texture mapping onto a square and resizing it but I find it is slower than pix_draw in this case. When rendering movies I've found that texture mapping is faster but the image is more distorted. I'm using GEM 0.87 under Linux. Is this a problem with pix_draw or is it supposed to work this way? I have a fast processor ( 1 GHz) a good video card (Nvidia 2Go) and I find movies are playing quite slowly. I only have 128 MB ram. Just ordered another 256 MB hoping this will speed things up. Wondering what other people are using to get realtime playback with MPEGs in Linux? Thanks, Jim

RE: [PD] scaling pix_draw in GEM ,and GEM performance question

pix_draw blits the image data directly to the screen, so you are correct, pix_scale will not have any effect (since it only works on geometry data, like triangles). In theory with any modern day gfx card, pix_texture should always be faster than pix_draw (there are a couple of edge cases, but I don't think that you are dealing with them). I used to get 4 mpeg streams on a 400Mhz box with a TNT easily. I suspect that more RAM will help though.

PD-Irix progress
by Søren Bovbjerg 10 Sep '02

10 Sep '02

Hi I managed to compile PD35 as Irix n32. I added -lpthread to the link options and the new objects seem to work. However: 1) The Gui is very jerky. Could the be because the tcl/tk (8.3.2) packake is located on a remote directory?(does PD need this directory at runtime?) 2) None of my externals work - not even old compiled irix6 externals that come with pd34. It cannot find the <external>_setup function.... I can compile and run them with PD34/o32. 3) I had to change some of IOhannes' additions to s_main.c and s_sgi.c. Though it compiles it will not run with sound with these new options for soundcards and channels. I added some #ifdefs to s_main.c in the -inchannels/outchannels parsers and the sys_open_audio call. I also reverted a few things in the public routines in s_sgi.c and added an empty sys_listdevs function. However, my changes are rather dirty and unchecked, but maybe someone (Miller) can use this info for something usefull. Cheers Soeren

*cast~
by august 10 Sep '02

10 Sep '02

Yves, Olaf, ppl, just wanted to step in and say I'm having still having some probs, found some minor bugs in both *cast~ externals... got the mono working on one machine but not the other. but, in principle they both work great. at the moment i'm working in a temporary setting...ill try to send some bug reports later this week. personaly, i think it would be cool to somehow bring the two together....but repetition also has its advantages. if anyone is interested, we (norbert math and myself) are putting it to good use at http://alien.mur.at/radiotopia direct link to the pd/flash app at http://http://195.3.99.130/radiotopia if anyone is interested in taking part...please contatct me <august(a)alien.mur.at> or norbert <n(a)alien.mur.at>. We have a pd machine here sitting on top of a large collection of sound files that have been uploaded to our database from various individuals. for example, if you have a patch you'd like to set to run over the files , we could download it to our machine and play it from here. Or if you'd like a half-hour or hour sesion controling the machine from remote (via OSC)....etc. open for suggestions. best - august.
