[PD] is pdp supposed to work?
Hi, I just downloaded Pd-Extended 0.42.5 for Ubuntu (i was using an older snapshot which had some troubles) and tried to open some pdp examples, but they don't work, at least not out-of-the-box. They don't open any window and there is no create message or anything that looks like it is supposed to open a window - so I guess it is supposed to open automatically, isn't it? Anyway if I send a [create( message to pdp_glx a window is opened but nothing happens in it. When I bang the metro in the examples, I start getting the following errors: pdp_v4l: auto open failed pdp_v4l: no device opened pdp_v4l: attempting auto open pdp_v4l: retry count reached zero for /dev/video0 pdp_v4l: try to open manually Any idea of what can be the problem? Am I missing something? thanks m. ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

HI. in my experience in Linux if your machine is relatively new you should replace the object v4l by v4l2, if you're on osx change the same for pdp_ieee1394- Pdp works very fine Bet regards José 2011/1/31 Matteo Sisti Sette matteosistise...@gmail.com: Hi, I just downloaded Pd-Extended 0.42.5 for Ubuntu (i was using an older snapshot which had some troubles) and tried to open some pdp examples, but they don't work, at least not out-of-the-box.

Degoyon's page only directly talks about PiDiP, Degoyon's add-ons to PDP. PiDiP is a separate library that works within PDP's framework. And contrary to PDP, PiDiP is non-free software, as in it's not FLOSS. I mean, where I can find answers to questions like: what is a packet? It's a piece of data together with a type tag. That's extremely generic, as in, it hardly specifies any structure at all. There's a corresponding message type that has the selector 'pdp', for carrying pointers around. After that, you have several type tag patterns that correspond to specific data formats such as float matrices and three kinds of images. What kind of data do pdp objects handle? What is the bare minimum you need to work with pdp (like [gemwin] and [gemhead] in gem)? Just like GridFlow, PDP doesn't have a central metro/window bundle like [gemwin] and [gemhead] are. Instead, a window waits to get an image into an inlet of its corresponding object. However, unlike GridFlow, PDP supports only one window per window-class (one for [pdp_glx], one for [pdp_xv], ...) whereas GridFlow supports one window per window-object, so that [#out x11] four times opens four windows. That said, PDP, just like GridFlow, doesn't need a window, in order to be able to do work. That is unlike GEM, except that since GridFlow introduced [gemdead] (sic), you can now use GEM pix objects without [gemwin]/[gemhead] and thus you don't need to have a window open anymore. ___ | Mathieu Bouchard tél: +1.514.383.3801 Villeray, Montréal, QC ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list

For more general packet stuff, there is pdp/doc/misc/layers.txt, overview.html, and pdp/doc/introduction The patches inside the introduction directory have been moved into the example directory in Pd Extended. I had overlooked them being inside the example directory, thinking they'd be similar to other example patches (which definitely are not aimed at someone not already familiar with the basics of pdp). The file layers.txt doesn't exist in misc, nor does overview.html but there is old-overview.html, which however, is very similar in content to the project's home page at http://zwizwa.be/pdp/ which doesn't explain very much. I'll have a look at the introduction patches and the help patches for the window objects, I guess I can start from there.
