Re: [PD] [Gem] performance issues on ubuntu (no hardware accel?)

Re: [PD] playing video+sound with Gem
sven, why do you need to know the framerate? i think actually just the kHz rate of the sample needs to be known. then if sample and video have the same length and you have the total number of frames... just devide them with the total of samples and you will know which frame goes with which sample, or not? no dead_chicken.txt in the end? i've tested that with gem already a while ago and sometimes i got the wrong number of frames. never really investigated why gem would report wrong number of frames. and how to get the samplerate info of an audio file? i'm sure there could be a way that doesn't need the extra info but i prefer flexibility / reliability and besides audio / videoinfos the extra file can also be used to store a lot more meta information that can be useful sooner or later. this of course depends on what you want to do. anyway the method above always works / worked for me so i didn't really bother to invest more time to eliminate the need for the chicken. sven. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] GRiPD and shell don't play well together
When I run pd with GRiPD library loaded, the shell external doesn't ever finish and a couple of calls to it eventually completely hang Pd. This is without the GRiPD library actually doing anything...just loaded. The GRiPD library seems to play well with other externals and the shell external works fine with everything except GRiPD. I am hoping this is an easy fix in the shell source code, as I can't seem to successfully build the GRiPD module so I am using the ancient .pd_linux binary included with its source code. I know the GRiPD is no longer maintained, but it happens to be perfect for our project so at least in the short term it makes sense for us to use. -John ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

dear hcs, i've changed it according to your suggestions. there is no play button because it should play right when you opened a sample. i suggest one wich is 1-5 seconds long with 44.1 kHz. if the rate is different then set it. the ftos object is used. i don't know wich library this is and how i should avoid it, some people apparently don't have it. i haven't tone very much in the audio domain and i would be happy to hear thinks like it should not be done like this because of ... rather use ... it will be better because ... thank you. easysampler.pd Description: Binary data Am 28.11.2006 um 22:07 schrieb Hans-Christoph Steiner: A couple comments: - hiding the implementation in a subpatch would make the interface elements much clearer. - adding english translations would help the non-German speakers - I couldn't find the play button .hc On Nov 28, 2006, at 11:04 AM, Max Neupert wrote: working version: sorry. easysampler.pd Am 28.11.2006 um 11:32 schrieb Max Neupert: hmm. this could fit in this thread i would like some pros to look at this patch to give me some grumpy feedback. thank you. easysampler.pd Am 28.11.2006 um 03:56 schrieb robbert van hulzen: i'm not really in a hurry at this point, so i'll continue poking around in what i have for the moment, but since the hurry will be getting on in about a week or so, i'm glad to know about your [play-samp~]. i actually know it (almost it) from your slicer~abs, and it looks like it'll be great to use as an example too. thanks. robbert Hallo, robbert van hulzen hat gesagt: // robbert van hulzen wrote: a good start indeed... still working on it, trying to figure it out. thanks!

Re: [PD] osc~ / phasor~ / cos~ ...sometimes clicking
Clicks are most often CPU / buffer related problems, however. On my laptop, for instance, I have to disable the wireless card if I want to use even a very simple PD patch and not get clicks, for example. I have to disable it for using other audio apps, also - but the problems in PD are always more severe than any other audio program. ~David On 11/28/06, day 5 [EMAIL PROTECTED] wrote: Consider that digital audio is represented simply as instantaneous pressure values for the speaker membrane.

Just out of curiousity, why did this project die? It seems to be one of the most promising/interesting approaches I've seen to using PD. Especially because of the severe problems that PD Gui objects currently cause in terms of hogging CPU... Although, admittedly it might be just as easy to run PD without the GUI and send OSC messages with an interface built in (insert program of choice). Is that why it's obsolete? I've been meaning to try this approach but haven't yet had the chance. In fact, generally I've been so busy doing web design + day job + putting out my first techno releases, I haven't had any PD time, but I'm dying to get back to a bit of PD work...

No. GLUT is a toolkit for making simple OpenGL applications. GEM uses glx directly. Perhaps your X11 is not set to a compatible pixel format? I think that is what causes glXIsDirect to return false (and triggers that message in GEM). 24 bit and 8 bit are supported in the glx code in CVS. ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

[PD] invisible py object on Windows
I have two machines with the same Miller Pd 0.39, Python 2.4.2 and py.dllfrom the 0.38 extended release, but on one machine the py object is not drawn in the patch window! The .pd file does have a listing for the py object and the py object can be patched. I found an email from about a year ago where Thomas said this was due to an old version of py/pyext. Since all I did was copy the Pd files from one machine to another, I don't know what the difference could be. Am I missing a DLL or something on the one Windows machine? ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

You mean the py external is invisible in root patches, but visible in subpatches? What about abstractions? Exactly the case - subpatches display the object but the top level patch does not. I haven't tried an abstraction yet. If the abstraction works I coudl simply roll one around the py object I suppose. I only use it in abstractions for actual work, the problem only happened with simple test patches. I never really was able to reproduce the behaviour... The binaries for everything are identical between machines so I have no idea what is the variable causing the invisible object. greetings, Thomas ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
