starting [pd~] causes: tcl: /usr/lib/bin/pd.tk: can't open script
by John Harrison 08 Mar '11

08 Mar '11

When I send [start( to [pd~] I get "tcl: /usr/lib/bin/pd.tk: can't open script" in the command window. since /usr/lib/bin/pd.tk didn't exist I tried ln -s /usr/lib/pd-extended/bin/pd.tk /usr/lib/bin/pd.tk still no go. I had also been getting other variations of file not found for watchdog and pd-gui but symbolic links appeared to fix those: ln -s /usr/lib/pd-extended/bin/pd-watchdog /usr/lib/bin/. ln -s /usr/lib/pd-extended/bin/pd-gui /usr/lib/bin/pd-gui pd 0.42.5-extended downloaded as a binary from the pd site, running on ubuntu Maverick workaround? -- John

There are some times when you have to know the sample rate beforehand, especially in delay situations where an algorithm depends both on the milliseconds of delay AND the actual number of samples. This can happen in reverb and filter design, and elsewhere. Otherwise this is also a problem in more obvious ways when you're playing sound files -- sometimes I'll make my patches so that if it detects the wrong [samplerate~] it tells the user to close the patch and fix it. Which reminds me: there used to be a problem with [delwrite~] where it would allocate its memory when the patch containing it loaded, based on the sample rate active at the time, such that if you switched Pd to a higher sample rate after the patch loaded, you'd have the same maximum number of samples of delay, but not the same maximum milliseconds. I remember there had been talk about fixing this, but if it's still a problem, this might be a reason not to set sample rate from the patch. Matt

How to view mjpeg broadcast in PD?
by Bart Koppe 08 Mar '11

08 Mar '11

Hi, I'm trying to view a mjpeg stream in PD, like http://193.40.245.184/mjpg/video.mjpg Is this possible? If not, is there a way around, and how? Using PD Extended 4.25 in Ubuntu Karmic Thanks greatly! Bart

FWIW, I would say if a patch is good then it does not matter what he wrote. If it does matter, then it's everyone's loss...

0.42.5 extended pix_mix segmentation fault
by olsen 08 Mar '11

08 Mar '11

Buenas the video mixer described on the https://gem.iem.at/docs/tutorials/PureDataGEMVideoMixerTutorialVideo segfaults on my computer as soon as one of the videos come to an end - both Videos are same size & mjpeg-codec. This happens on Ubuntu 10.04 with 0.42.5 extended. Same patch and videos runnning flawlessly using pd-vanilla & GEM-svn. On a OSX machine and 0.42.5 extended also no problemo except the video on osx are looping by default and on Linux not. any hints welcome salutis ø -- ETs DNA will not be televised http://hasa-labs.org

Re: [PD] Get list of a the arguments of a patch without using any external?
by Matt Barber 07 Mar '11

If you need to get the arguments to use within the abstraction instance itself, you can do it using the [list-argv] patch I've attached (see the help file). It requires a helper subpatch on [list-argv]'s parent (i.e. the abstraction you want to use it in). This employs an idiom by IOhannes which has seemed to be pretty robust. Warning: there is some dynamic patching that goes on in the helper subpatch to make this work. I use this a lot for abstractions that need to be able to take a variable number of arguments.

Right. We discussed before somewhere on the list but I couldn't figure out where. Here's the same solution but only using a subpatch. Just use "testab.pd" as an abstraction, give it some args, and bang [pd get-my-args] to get your args. (Then just copy/paste [pd get-my-args] into any abstraction where you want to get the args.) -Jonathan --- On Mon, 3/7/11, Matt Barber <brbrofsvl(a)gmail.com> wrote: > From: Matt Barber <brbrofsvl(a)gmail.com> > Subject: Re: [PD] Get list of a the arguments of a patch without using any external? > To: pd-list(a)iem.at, "Alexandre Quessy" <alexandre(a)quessy.net>, "Jack" <jack(a)rybn.org> > Date: Monday, March 7, 2011, 8:28 PM > If you need to get the arguments to > use within the abstraction > instance itself, you can do it using the [list-argv] patch > I've > attached (see the help file).

Pitch envelope
by Ed Kelly 06 Mar '11

06 Mar '11

So... A sample has duration (x) A breakpoint envelope has pitch transposition from -60 to +60 semitones. How do I work out what that would mean for the duration - i.e. how do I make it so the whole pitch envelope happen within the duration of the sample? I'm not a mathematician, and have been looking at integration, but I can't work it out. Can anybody help me? X Ed Metastudio 4 for Pure Data - coming soon! Metastudio 3 still available at http://sharktracks.co.uk/puredata
