Hey thanks, these first two paragraphs got me on track. Much appreciated.

Hi folks, it's been a few years since I last used Pd, and I'm having trouble getting it up and running on Ubuntu 14.04. Does anyone have a decent tutorial that includes audio (ex. Jack) setup? I followed the instructions here but the resulting install starts up with a load of errors and no working midi or audio: http://puredata.info/docs/faq/debian

My google searching has mostly turned up recommendations to use some other audio-specific distro (KX) instead of Ubuntu, but I'm not interested in installing a new OS for a single application.

Any help is greatly appreciated, thanks!

Today is the official release of Infinite Glitch, an online based artwork that was created using, among other things, Pd-extended and PdGst. Thanks so much to everyone who has helped with the development of these great tools!

Every day an incomprehensible number of new digital media files are uploaded to hosting sites across the internet. Far too many for any one person to consume. Infinite Glitch is a stream-of-conciousness representation of this overwhelming flood of media, its fractured and degraded sounds and images reflecting how little we as an audience are able to retain from this daily barrage.

Infinite Glitch is an automated system that generates an ever-changing audio/video stream from the constantly increasing mass of media files freely available on the web. Source audio and video files are ripped from a variety of popular media hosting sites, torn apart, and recombined using collage and glitch techniques to create an organic, chaotic flood of sensory input.

I'm attempting to use pdp_theonice~ to stream theora video to an icecast server. I'm having trouble getting this working - it seems to connect ok as long as there is audio and video being sent to pdp_theonice~ but I can't view the stream with vlc or an embedded html5 player (which I've been able to do when streaming video from other sources to this same icecast server). oggcast~ works just fine.

Does anyone have a simple patch that they know works for streaming theora video to icecast with pdp_theonice~?

I've checked out the giss examples, but these are way more complicated than I need, and hard to debug. Also, they crash when I try to connect (probably because no audio or video is making it to pdp_theonice~, as my tests have shown that pd crashes when you try to connect without audio and video).

I am on Ubuntu 10.04 with Pd-extended 0.42.5.

Thanks!

p.s. alternately.. if there's another way of streaming theora without pdp_theonice~ (using 3rd party software or otherwise) I'd be interested to know this as well.

p.p.s. I already posted this to the list, so I'm sorry if you're now reading this twice.

Is there a way of creating abstractions with the equivalent of [initbang] in pd-vanilla?

Thanks to Max Flämig, Pd t-shirts are now available for mail order here:
http://puredata.info/Members/mfla/banguntil/

Proceeds will be put toward developing better, more complete documentation for Pd. Exactly how has yet to be determined, but there are a few ideas in the works.

Thanks to hardoff for the design concept.

Here's an abstraction inspired by hamster's recent post (http://puredata.hurleur.com/sujet-4261-midi-learnable-mixer-channel).

It adds learned MIDI control to your patches. Learned MIDI settings may then be saved in a text file for loading later. You can create as many control objects as you need, and all settings will be saved to a single text file. Works with both control and note MIDI values.

(note, saved settings do not include current control values, just the learned channel and control/note numbers)

It's called bb_learn and can be downloaded here:

I just wrote up a guide for streaming mp3 audio to a free Shoutcast host.

Anyone know if you can use the OpenGL GLX extension with GEM?

I am a complete and utter noob when it comes to OpenGL, but it seems like this would make it possible to send gemlist data over a UDP network connection. My initial tests seem to indicate that GEM does not support GLX: I tried GLX objects like [GEMglXCreateContext] but they didn't create.

I'm ultimately looking for a way to stream from GEM to a remote computer over the internet, without using the processor intensive [gem2pdp] object and [pdp_theonice~]. Alternatives to GLX or PDP are very welcome too.

I just uploaded a few new abstractions:

Included are:
-sample player
-a much more comprehensive sampler-slicer-looper
-gui file browser
-modular, multitrack audio recorder

Let me know if you run into any bugs.

I've been away from PD for the last 6+ months, but am happy to be back. Here's a bit of color to brighten up your day.

(youtube's been performing a bit better recently)

First results from a feedback patch I made last night using Gem. It's based on a patch that was posted on the list recently, unfortunately it escapes me who made it exactly...

Anyway, check it out. Not a finished piece by any means but just a taste of what's possible when playing with video feedback and audio response patches in Gem.

(If anyone wants the patch to play with, I can provide it. You can also just search the pd-list archives for recent posts on the subject of feedback in PDP and Gem)

I currently use a Macbook (OS 10.5) for all my PD patching. However, as I am primarily focused on using GEM for live video performance alongside musical groups, I am thinking about getting a second laptop for performances (to keep my Macbook safe).

I'm thinking of getting an Acer Aspire One netbook running linux.

I'd like to know the pros and cons of this.

-Will swapping patches between Mac OS and Linux be a problem (I'm guessing no, but I figured I'd ask)?

-I've heard of some problems with VGA out on Linux laptops, is this going to be an issue?

-Does the netbook have enough processing power for general GEM applications? I'm generally not dealing with video files, but rather particle generation, shape manipulation, GIF texturing, and audio-response.

-Are there any other issues that you think of given this scenario? (and if so, what other affordable/really-cheap laptops are there out there that I can run linux on)

the last two inlets on [pix_duotone] are supposed to take in rgb values, but actually they take in gbr values (green, blue, red)

I'm trying to create a posterize effect patch for video (using GEM). I found one in the PixelTango object [pt.layerfx] but I can't seem to figure out how to access the GEM subpatch that powers it. Can anybody tell me how to access the posterize subpatch in [pt.layerfx]?

Alternately, can anybody give me advice on how to create a posterize patch from the ground up? Basically I'm trying to reduce the number of colors in the video image. I don't even know where to begin so anything will help.

Thanks!

I am working on a patch to use audio information as a triggering mechanism for live video effects. Basically, right now I'm trying to produce bangs on bass or snare hits. I am attempting to isolate the hits using a lowpass [lop~] and bandpass [bp~] and [highpass~] filters (though only a lowpass is used in the patch that I'm posting, any combination of filters can be inserted in it's place). [moses] only sends information from the right outlet when the signal received from [env~] (a measure of amplitude) is higher than the "trigger cutoff" sent to the right inlet.

I want to use this to manipulate video projections during live shows using the audio the band is putting out. Does anyone have any advice for better ways to isolate specific frequencies so I can narrow the triggering down to just the hits I want to trigger bangs?

can anybody tell me how to use pix_zoom? i've attempted a couple setups but can't get it to have any effect. i'm trying to create a throbbing effect in a video clip by zooming in and out to a pulse. is there a better way to do this in gem? should i be using pdp to do this? i know gem better so i haven't really explored that option.

i'm trying to control midi with an Oxygen 8 usb midi keyboard (2 octaves of keys, and 8 programable control knobs). i can't seem to get pd to recognize it in the midi preferences menu, and [ctlin] and [notein] objects aren't picking up any signals. i'm running mac osx 10.5 and pd-extended 0.40.3.

if anyone could tell me how to get pd to recognize this usb keyboard i would greatly appreciate it.

You could have the pause button mute it right before it hits the [send~]

Thanks for the "Thanks" Keith, glad to have helped!
