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

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.

Thank you, that worked!

By the way, apart from help patches documenting each object and example patches, is there some getting started guide or complete manual explaining what pdp is in the first place?

thanks m.

Sure, in the page of project:

http://ydegoyon.free.fr/pidip.html

Hi,

Thank you, but that seems to me more of a reference (or even a mere list) of individual objects. I'm looking for an introduction or getting started guide,

I mean, where I can find answers to questions like: what is a packet? 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)?

Is there such a guide or reference manual? If not, I guess I can learn it by looking at help patches but what objects should I start from?

thanks m.

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.

Yes kind of guessed that, but I was directed there in response to asking about a general pdp introduction...

It's a piece of data together with a type tag. (...) After that, you have several type tag patterns (...) Just like GridFlow, PDP doesn't have a central metro/window bundle(...)

Thank you very much. Is all that documented somewhere?

thanks m.

For more general packet stuff, there is pdp/doc/misc/layers.txt, overview.html, and pdp/doc/introduction, and so on... all of pdp/doc

Ok I knew I had to be missing something. Where is all that stuff located?

I have no "doc" folder in /usr/lib/pd-extended/extra/pdp nor do I have any "pdp" folder inside /usr/lib/pd-extended/doc ...

Thanks m.

PDP's presence in Pd-extended is quite truncated. I don't know why (doesn't make sense). You have to download a source package from PDP's site instead.

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.

Thanks again m.

Thanks for saying the word "wrong" in answer to the appropriate paragraph.

I don't know what the rest of your reply means though, and frankly, I don't want to know. :-|

Erratum :

I remember having to do something like use one object of each class for the purpose of doing something, but I don't quite remember what it was, and I'm pretty sure it was in 2004 or 2005. The PDP currently on my machine can open multiple [pdp_glx] windows and [pdp_xv] windows.

Now that I think of it, it probably was instead something to do with multi-screen video cards that would only allow GL on the first screen.

Using multiple windows using GEM ? Or using one GEM window per instance of Pd and have many Pd instances ? What was your problem with GEM and gemwins ? ++

That's not PDP's page.

But clicking on the link it has to PDP's page (on Tom Schouten's site) : http://zwizwa.be/pd/pdp/

And then clicking on "introduction" : http://zwizwa.be/pdp/

You see that the only documentation it talks about, is help patches.
