Re: [PD] two scale objects?

What's the best way to avoid trouble with that? Probably not using Cyclone and maxlib at all i guess... thanks, max Am 19.09.2005 um 16:34 schrieb Urs Liska: > There is also a [scale] object in maxlib which can also be named > maxlib_scale. > But this probably won't help you. > > Best > Urs > > IOhannes m zmoelnig schrieb: > >> Max Neupert wrote: >> >>> hi list, >>> >>> i had a strange thing with [scale] happening. after reopening >>> the patch it was a different object with more inlets.. are there >>> two scale objects? is it a name clash? the workaround was to >>> use [scaleXYZ] for now. >>> >>> >> yes it's a name clash; i think the other [scale] is in cyclone. >> mfg.asd.r >> IOhannes >> _______________________________________________ >> PD-list(a)iem.at mailing list >> UNSUBSCRIBE and account-management -> http://lists.puredata.info/ >> listinfo/pd-list >

gem font rendering
by Tim Blechmann 19 Sep '05

19 Sep '05

hi all, i'm currently fighting with gem's font rendering: my goal should be pretty easy ... i'm rendering a couple of text lines on a screen (text2d) ... these text lines are moving synchronized from the bottom to the top. but to my eyes it seems, that these lines are not in sync ... but that they are jittering ... all text2d objects are scheduled by the same gemhead, the movement is done by separate translateXYZ objects, that are fed by a line (realizing the movement by a single translate XYZ object didn't help, either). is there any way to improve the font rendering to avoid these problems? thanks in advance ... tim -- mailto:TimBlechmann@gmx.de ICQ: 96771783 http://www.mokabar.tk latest mp3: kMW.mp3 http://mattin.org/mp3.html latest cd: Goh Lee Kwang & Tim Blechmann: Drone http://www.geocities.com/gohleekwangtimblechmannduo/ After one look at this planet any visitor from outer space would say "I want to see the manager."

... M-audio and pd asio problem
by guillaume rabusseau 19 Sep '05

19 Sep '05

Hi, I have a problem with my sound card, which is a m-audio firewire audiophile. I can't manage reaching a low latency in pure data : When I use shareware like fruity loops or Live Lite, the shareware automatically detects the buffer size i have specified in the control panel of the sound card and tells me what latency it gets, with a 256k buffer size i have a 5 ms latency (which is good for me).But in pure data, using the M-Audio FW Asio driver, as soon as I try putting a latency less than 60 ms, the test tone becomes very dirty, with a lot of discontinuities. I have tried a lot of combinations with -audiobuf -blocksize... but i simply don't manage to do it. If you have some ideas i would be very glad. Bye. P.S. : i have tried with pd 0.37, 0.38 and 0.39 on windows XP _________________________________________________________________ Retrouvez tout, instantanÃ©ment, sur votre PC, avec Windows Desktop Search ! http://desktop.msn.fr/

lpc externals
by Ed Kelly 19 Sep '05

19 Sep '05

Hey guys, http://members.lycos.co.uk/speechcodingpd/lpc.tar It was great to see you all in Spain those who came. As promised here is the link to the lpc externals I've been working on with Nicolas Chetry. The re-synthesis of the voice from residual and PARCOR coefficients is seamless - but this makes it quite dull as you get pretty much the same as you put in. However, the cross-synthesis is the fun part... I'm working on a voicing detector to be used with fiddle, so that a more synthetic effect may be generated. More on this soon.

Hi, tried a new Distro (ccrma) but with that settings Gem (0.90) does not like my webcam. there is some output, but only in the upper side of the window. and it is distorted, i have like 4 stripes side by side. How can I configure the settings of the webcam? The picture looks good in other applications. cu! marius.

glibc pthread_join freezing on sarge using PD/pdp/Gem software
by B. Bogart 18 Sep '05

18 Sep '05

Hello all, Sorry for the cross-posting. I'm running a stock sarge machine with the 32bit 2.6.8 kernel on a AMD64 3200+ machine. I'm using some unstable and demudi packages for media applications, in particular pure-data (PD). Problem I'm having is that PD crashes when I try and use v4l2. Actually there is no fault, but PD hangs. I traced it down to the use of pthread_join() which is where the code hangs. (I've been doing a backtrace after manually killing the application) I tried upgrading my libc6 2.3.2.ds1-22.d to 2.3.5 and am still getting the same crash. Here are a couple examples of traces: (gdb) bt #0 0xffffe410 in __kernel_vsyscall () #1 0x40128f18 in pthread_join () from /lib/tls/i686/cmov/libpthread.so.0 #2 0x44bd97bd in videoV4L::stopTransfer () from /usr/lib/pd/extra/Gem.pd_linux #3 0x44bd504c in pix_videoNEW::stopRendering () from /usr/lib/pd/extra/Gem.pd_linux #4 0x44b0111e in GemBase::gem_startstopMess () from /usr/lib/pd/extra/Gem.pd_linux #5 0x44b01382 in GemBase::gem_MessCallback () from /usr/lib/pd/extra/Gem.pd_linux #6 0x0809ba47 in pd_typedmess () #7 0x00000000 in ?? () (gdb) bt #0 0xffffe410 in __kernel_vsyscall () #1 0x40128f18 in pthread_join () from /lib/tls/i686/cmov/libpthread.so.0 #2 0x42a86440 in pdp_sdl_setup () from /usr/lib/pd/extra/pdp.pd_linux Gem.pd_linux & pdp.pd_linux are libs loaded into PD. I have recompiled Gem.pd_linux from source and it still crashes. Possible issues: PD is from the demudi (stable) package Gem is compiled from source PDP is from the demudi (stable) package The crash still happens on libc6 2.3.2, and 2.3.5 If this crash is caused because the packages were compiled against a different version of libc6 I tried to compile PD from source as well. So with Gem compiled from source and PD compiled from source (both against libc6 2.3.5) I still get the crash. No other libs are noted in the backtrace, could one of the other libs actually be the cause? Gem links with libmpeg3,libmpeg,aviplay,ffmpeg etc.. But I don't see any calls to these in the trace... So to recap, PD and Gem are recompiled from source against my libc6 2.3.5 (unstable) pthread_join() still crashes, only these two packages are in the trace... So what is causing the crash? Any suggestions, especially for debugging beyond the gdb backtrace, would be greatly appreciated. I've read of some people have issues with AMD64 and pthreads, but those seemed to get resolved by upgrading to libc6 2.3.5. So what should I do to try and solve this? Are there known bugs with my configuration and pthreads? I'm doing an art installation on this machine in just weeks so I really need to get it working or I'll have to resort to dropping linux and going to an OS X machine. :( Thanks all for your time and attention. B.

pd-devel and expr
by Johannes Burström 18 Sep '05

18 Sep '05

Hi A few days ago i checked out and built pd devel 0.39 from CVS. I found that expr, expr~ and fexpr~ doesn't load properly: /usr/lib/pd/extra/expr.pd_linux: /usr/lib/pd/extra/expr.pd_linux: undefined symbol: ex_mkvector load_object: Symbol "expr_setup" not found expr ... couldn't create All the other externals (bonk~, fiddle~...) works just fine. Does anyone have a clue on what to do about this? Regards, Johannes
