Can anyone shed some light on this error? I get it sporadically and it doesn't seem to be a big deal, but still thought I'd post it for teh lulz.

I'm on Debian Squeeze and aren't able to get the zexy library to work. I've tried installing the packages (including pd-zexy) from the puredata repos, pd-extended different versions/nightly builds and installing packages from the puredyne repos but everytime I get the same message;

zexy: can't load library

It's located in /usr/lib/pd/extra/zexy/ but Pd searches for /usr/lib/pd/extra/zexy/zexy.pd_linux and that file doesn't exist. The file z~.pd_linux does exist, copying that as zexy.pd_linux doesn't work either because then the 'load_object: Symbol 'zexy_setup'' isn't found.

Are there more options I can try? I read something on the forums about zexy being scattered on OSX, is this also the case on Debian and do I just have to wait for a fix?

I have an ATI Radeon card with the Mesa driver. Whenever I try to create a new gemwindow PureData quits on me. Can anyone explain some more about this fatal error?

Hi,

I am trying to use the midi-out function in Pd (in combination with JACK (and minicomputer)) but everytime I turn it on JACK keeps pumping out the 'ALSA connection graph change' message.

It was working some time ago but I don't know what has changed, can anyone give me a suggestion of what to do since I'm having difficulties with this one! (not quite a linux audio expert here...)

Thanks!

I'm using Pd-Extended on Ubuntu Gutsy. When I open the example Gem (pix) movie patch it works perfectly. I can rotate the cubes while texturing the given homer.avi/anim-1.mov/alea.mpg and switching or stopping them a 1000 times.

Whenever I use my homemade avi/mov/mpg files Pd crashes... I've tried several encoding options and got some results for all of them - but switching video or stop/start autoplay still results in a crash. Also Pd seems to stop playback at the end of the file instead of looping it.

I think I'm nearly at the point of success with the mpg file, look at the output of the file command;

file alea.mpg (working)
MPEG sequence, v1, progressive Y'CbCr 4:2:0 video, 320x240, 4:3, 30 fps

file test.mpg (partially working)
MPEG sequence, v2, MP@ML progressive Y'CbCr 4:2:0 video, 320x240, 25 fps

Does anyone know how I can get the settings right? Searching for 'file mpg' on the internet isn't really productive... So far I've been using Avidemux for mpeg settings.

I've made a patch to compare 2 numbers and calculate the range between them. It works! ...but strangely not always - sometimes it outputs the wrong number, like something got stuck along the way and a number that I gave in previously is compared to the new #1 or #2.

I can't seem to find out what's the problem, although I have a hunch it occurs more often when I use the same numbers (like 0 and 0) or make use of one or two negative numbers. To me it occurs just too random to make sense, anyone has an idea what could be wrong?

Hi,

I've created some timers which count from/to given numbers in given time. They do work but I would like some suggestions for a different/better way. Just trying to learn something here

I've included the patch but the png is also viewable at;

Also I'm working on a Gem patch with a timeline, if anyone knows of a basic tutorial about storing/retrieving values within a timeline please comment!

Hi!

I've just installed Pd and Gem on Fedora 8 via the Planet CCRMA Repoview. It seems to have installed OK... but using the gemwindow 'create' message crashes X, no errors just blackness followed by the login screen.

I made sure my ATI card is installed ok (proprietary) with direct rendering on before even attempting to install Pd & Gem. Sound patches work fine sofar.

Does anybody know what might be the problem or how I can 'backtrace' it?

Your patch gave me some good insight & help Maelstorm, thanks!

Anyone find a solution for this yet? I'm having the same problem on MacOSX and haven' t been able to "solve" it with a texture object.

Thanks for responding! I can install pd-zexy this way too, but afterwards it's unusable.

Does the console say that zexy is loaded on startup? Can you create zexy objects like [repeat]?

Hmz seems to be already know as a broken/orphaned package over at debian.org. All information is found on http://packages.qa.debian.org/p/pd-zexy.html

Commence weeping.

Well after reading a lot on the subject I did what I probably should have done in the first place... Uninstall puredata & components and reinstall them. Now it seems to work.

Oh well, another lesson learned.

Try the pix_movie helppatch to see which (avi/mov/wmv) works with your system. Then using ffmpeg determine the settings of that file;
ffmpeg -i anim.mov

• and recode your videofile accordingly;
  ffmpeg -i yourfile.mpg -an -vcodec mjpeg newfile.mov

This is what worked for me at least, check the ffmpeg faq and 'ffmpeg -formats' for more information.
If none of the supplied movies in the pix_movie help patch work it might be time to add some multimedia repos to your Debian Etch.

Ok... so I found out that Avidemux doesn't support mpeg1 video. And that mpg doesn't work as flawless as I thought before on my computer. Avi neither. QuickTime does however, when encoded in MJPEG.
Here's the one line that helped me;

ffmpeg -i file.mpg -vcodec mjpeg file.mov

Thanks a bunch! Didn't know about the min/max objects yet and this sure helps.

Dang!!! Can't believe I forgot about the hot-cold inlet thing!

Oh well... should be solved now (I think...) and I've gained some more insight. If anyone has some patch for summoning intelligence please let me know

Connect a messagebox [file /path/prefix 80] to [pix_write], where 80 can also be a different number. Don't forget to bang/click it before banging pix_write and it should output .jpg files.

The just released version 0.91.0 of Gem has a recording(!) option mentioned in the changelog... Haven't found any documentation online about how to use it yet.

Does anyone have some more information on how to set up my controls so my controls are recorded to one master file? Delta and times help patches didn't help me in this case.

Ah I did have the numbering but I had a trigger object connected wrongly to my gemhead. Tnx!
