[PD] [pix_video]: no valid video backend found

[Steffen Juul Christensen]

Dear pd-list,

I can instantiate [pix_video], but not find and use the build in webcam of my 
computer.

I’m running Pd Pd 0.45.4 32bit with
GEM: ver: 0.93.3 
GEM: compiled: Nov 10 2011
on a Macbook Air running OS X 10.9.1

The [dialog( message does not open a dialog window.

Sending [enumerate( makes Gem print the following to the console:

"videoctl: enumerate
could not get SG channnel Device List
[pix_video]: no devices found”.

When [pix_video] is instantiated it claims that 

"[pix_video]: backend #0='Darwin'   : darwin dv iidc analog “, 

but none the less I’m told that

"[pix_video]: no valid video backend found”.

A Open CV library for Processing 2 ensures me that the camera does work.

Using Pd-extended (shipped with Gem) doesn’t help me.

Any help/clues are appreciated. I’m sorry if this is trivial or a faq. I’ve 
search the archives with no luck.

Best,
Steffen

build the pd binary and drop it in to the latest Pd.app from Miller's

to be the problem with newer versions not being the standard for

It didn't really fail. IT just doesn't assemble a .app - as Volker

To cut a longer story short:

- No i don't want everyone to live there life linearly. How could  
that at all be assumed. (I rather embrace the opposite.)


- The Pd tutorials that Miller ship with Pd is bottom-up. That is the  
didactic contract with the reader. So if you want a canvas'ified-gui- 
volume-control with such use of canvas with graph-on-parent, it need  
be introduced first. That could be done in the "2.control.examples"  
section.

If it is encapsulated in an object, then the complexity is hidden

abstractions. Then GOBified abstactions that use [cvn] tricks to make  
a "funky" interface. The syntax of the last is way different from the  
first and different from the rest too in the way that the syntax is a  
"graphical design matter". GOP asb inherent syntax from the Pd it

The interface builder (mrmrIB) doesn't seam to run on 10.4 but on  
10.5 - so your are lucky. I haven't tried the IB yet as i don't run

Re: [PD] Keyname Object Changed?

Are such differences (in the core objectclasses) between Pd-extended  
and Pd(-vanilla) documented somewhere?

I can't tell you how you should go about it, but i think it would be  
nice if such things as core objectclasses worked the same on both  
vanilla and extended. (Or if thats not a possibility - as i assume  
the case is here - then maybe issue a warning?) Anyways, it alters  
the meaning of "works with Pd-extended" to "even if you install and  
load the externals needed it might not work with vanilla".

Sorry if i sound harsh but i think it's quite serious matter.

First off, i'm the slack bus-hit someone that didn't complete the  
gallery (ie. the exhibition) section mentioned.

I have been meaning to get back about it, but decided to not do it  
till i had more solid things to offer then ideas. Well, now i'll have  
to push in the ideas without the solid stuff. I'll be brief and leave  
out (most of) my reasons:

* I think the exhibition section should be discarded. It has in parts  
been replaced by a goto10 project (that reach much wider in scope  
though) and more importantly - to put it diplomatically - the  
publishing scheme is not compatible with the target community.

* There should instead be made weblog sync point for Pd related  
weblogs posts á la ProcessingBlogs. It should be simple to manage:  
Anyone wanting their Pd related weblogs posts to be in the common  
feed should supply a feed url with a "tag" for the Pd related posts  
in their feed. Either to a person doing the management (could be done  
in turns) or if possible through the IEM/Pd.info/plone-setup thing.

* Also there should be a concise wiki page with examples of what  
could be done with Pd. People writing that would want to suppress  
there ego for a second and think about what newcomers would most- 
likely want to see when looking into what Pd is by what can be done  
in Pd. Also therefore it shouldn't seek all the outer limits but  
include stuff like a simple algo-composing and loop-sampler example.

I think you a free to name your code what you want. And also to  
delete it. I however think people would find it interesting with a  
"lib"* of tabread's with different interpolation schemes.

At least i think it would be cool with a collection where also the  
interpolation methods of the "others" are included (fx, the SC one).

Thanks for publishing.

Depends on what it is to be different from. If it is to be different

Witch is a good enough reason to keep it, imho.

I much prefer Frank's suggestion. I.e. using the tabread4 name for a
/class/ that offered a bunch of /methods/ - f.x. one like how tabread4
does now and one like how tabread4c.

When using a [shell] object you'd really wanna run a script. Since  
it's a new shell that's opened each time you query it.

So when you do [cd /to/som/dir(/[shell] and then after wards to [pwd(/ 
[shell] then you'r no longer cd'ed to /to/some/dir but get the root  
dir. You can make a simple shell-script that both cd and pwd and then  
run that script. That is if you want to use a [shell] object.

I agree.

And the same goes for the other way around. That would be very good  
for giving the help browser a bash, especially (dynamically creation  
of) the reference section (based on path settings). If they (the  
helpfiles/classes/libs) are in the same dir going the route HCS  
surest, that is to do it in TCL, might also make auto/tab-completion  
in object-boxes within reach. - Humble ideas.

If there was such option in Pd-extended then people could do either  
of two to save preferences for Pd-extended:

1) Enable 'use "internal preferences"' and edit those.
2) Disable 'use "internal preferences"' and edit the normal preferences.

It should properly be disabled as standard to suit most users need.

See /trunk/doc/additional/pd-msg/ of the SVN repo at SF.
Those tut/docs are also shipped with Pd-extended.
Not that this so-called "dynamic patching" is doable but unsupported.

KDE seam to have both Apply and OK (and Cancel). But i don't think the
actual UI need be platform dependent. That is, i think it matters less
then having multiple buttons with different names that hint much the same
functionally but don't nessacarily supply that functionality. Apply, Ok
and Save in this case - as explained earlier.

One easy solution is to remove the Save button and add the save
functionality to the Ok button. And then either remove also the Apply
button or add the save functionality to that also. So where

Save:= Saves changes to file ready for next startup of Pd
Cancel:= Cancels i.e. quit the dialog

we have:

Case i:
Cancel
Apply:= Save
Ok:= Apply + Cancel

Case ii:
Cancel
Ok:= Save + Cancel

That said, I'd like to underline that i think the improvements already
done are much more impotent then this clearing of confusion of the UI. I
shall rest my case now (or submit a patch).

(FWIW.) To make a patch and submit it to the patch-tracker as SF.  
Then a few things can happen (and some combinations):
1) Miller accepts it and it gets into vanilla section of SVN 2)  
Miller doesn't accept it and it doesn't get into vanilla 3) Hans subs  
the patch to SVN and use it for Pd-extended.

Looking really good! The browse functionality is a fair idiom in a  
such GUI as oppose to entering text, i think.

"One" comment: I have a beef with the functionality of the buttons.  
Not the Cancel one. The others. 'Apply' does something. 'Ok' does  
'apply' plus 'cancel'. 'Save...' does 'Apply' plus saves. But it says  
the list is only gonna work from next time Pd is lunched, why i don't  
get the 'Apply' and 'Ok'. 'Ok' should do save and cancel. Thats all  
one wants, anit?

For the path/lib pref panel, the attached is what i got at when i

sketching need no edits to Pd source code but tries to black-box test  
first. Depending on the actual implementation one might need to patch  
s_path.c, hence recompile Pd to do a full test (as opposed to just  
swap main.tk). IOhannes recently got a patch for adding more path/ 
libs into Vanilla that gives more then 10 variables to work with in  
the Tcl side of Pd. A better fix would be to use another format (not  
assumed in my test) then pd_path0, pd_path1, ..., pd_pathN - like a  
'pd_path' array.

I gotta point out that my intention was not to be rude, but rather to

no (the assumption in the above is not true). according to the

are consistent with each other. Ie. left inlet sets the exponent and  
the right inlet and the argument sets the base.

Right. I think odd naming like **~, power~ and the like cause more  
harm then if the inlets are "swapped", since they are harder to  
recall or guess for both current and new users.

And to be frank, does it really matter if it's one way or the other?  
I mean, they are both "hot". So it only a matter of what one would  
think is natural or the convention or how you'd normally use such  
function. I'm very sure i have a TI calculator floating somewhere  
where it is the "cyclone/max" way. So there is no right thing only  
preferences, and no trigger-particle issues, hence in that respect i  
can not see how it contradicts with current Pd tilde-class behavior.

just my opinion.

For what i know there is some extra magic (that you request in

Allow me to chime in. I don't know if this is trivial from the list- 
abs or maybe comes as a special case in one of them. But here goes.


[list-alter-idx] takes tree inputs

2) an idx or the list element key (counting from 0)
1) a list in which element number idx will be altered by
0) the new input,

and returns the original list but with element number idx altered.  
Makes sense? See attached.


It's whoever not robust as if idx is greater then list-length, it  
misbehaves. It depends on list-abs. It's inspired by RTC.
