[PD] Problem Setting Up a Camera with Gem Using a udev rule on Ubuntu

[Jim Ruxton]

I want to set up a couple of cameras using udev so I can plug them in and
get them working without having to query what /dev/video# they are.  I set
up the following rules.

ACTION=="add",SUBSYSTEM=="video4linux",ATTRS{idVendor}=="046d",SYMLINK+="HDPro"
ACTION=="add",SUBSYSTEM=="video4linux",ATTRS{idVendor}=="30c9",SYMLINK+="Webcam"

This appears to work:
$ ls -l /dev/HDPro
lrwxrwxrwx 1 root root 6 Feb 20 19:33 /dev/HDPro -> video3

$ ls -l /dev/Webcam
lrwxrwxrwx 1 root root 6 Feb 20 19:32 /dev/Webcam -> video0

However using /dev/HDPro and /dev/Webcam as the devices for Gem doesn't
work. Actually whichever one gets /dev/video0 it seems to work. But I have
to use /dev/video2 to get the HDPro to work which is strange because it is
actually linked to /dev/video3 as shown above.  Any idea how I can get udev
to work correctly with Cameras and Gem? I'm using pd 0.53.1 and Gem ver:
0.94. "Debian/1:0.94-7"
Thanks!

[PD] Getting GL[1286] Error Message in Gem

[Jim Ruxton]

Wondering if anyone knows why I keep getting an error message:

" GL [1286] Invalid framebuffer operation " when using Gem on OSX 
10.14.6 . I'm using the latest version from Deken. This doesn't happen 
in Linux. The gem window seems to render ok but the error must be 
messing with the CPU because it is causing major glitches in the sound.


 I get this error when I try a simple patch such as the circle help file.

Thanks for any advice on this.

[PD] Ofelia on Ubuntu 19.10

[Jim Ruxton]

I am trying to install ofelia on Ubuntu 19.10 and PD 0.50.0 and having 
issues. If I try to install  the latest version v3.1.0 on Deken I get a 
conflict because 19.10 doesn't have |libGLEW.so.2.0 |available. I then 
tried to follow instructions for compiling the external myself from 
https://github.com/cuinjune/Ofelia/issues/8#issuecomment-463173798 using 
OF 0.10.0 . I was successful compiling it and get this in the console 
after replacing the binary in the /externals/ofelia folder with the 
newly compiled one:


ofelia v2.0 : compiled on Apr 30 2020
(c) 2018 Zack Lee 

but none of the objects worked ie. dashed lines around all of them when 
testing examples and lots of "couldn't create" in the console. Also the 
"ofelia function" object didn't work. I also tried using this binary 
with v2.3.1 in Deken but that also didn't work. I have ran the  
"install_dependencies.sh" script successfully. Can someone who has 
ofelia working on Ubuntu 19.10 help me figure out what I need to do to 
get this working. I have used older versions of the external in the past 
and really like it but would like to move to the newest version if 
possible. I am probably missing something simple but not sure what.


Thanks,

Jim

[PD] Gem Crashing On Ubuntu 19.04 with pix_video

[Jim Ruxton]

I recently updated a bunch of software so I am not sure at this point 
what is causing this instability. I went from Ubuntu 18.04 to Ubuntu 
19.10 and PD 0.49 to PD 0.50 . Gem is version 0.94 . Previously when I 
selected a device that didn't exist in the pix_video help file I would 
just not get any output in the Gem window. Now if I select a device that 
doesn't exist for example device 2 when only my laptop camera exists PD 
hangs up. I am not clear why but when I send an enumerate message to 
pix_video if no external camera is selected I get 2 devices ie.


info: device /dev/video0 v4l2
info: device /dev/video1 v4l2

If I add a USB camera I get 4 devices:

info: devices 4
info: device /dev/video0 v4l2
info: device /dev/video1 v4l2
info: device /dev/video2 v4l2
info: device /dev/video3 v4l2

Previously before upgrading I would select device 0 for my laptop camera 
and device 1 for a USB camera. Now I have to select 0 for my laptop 
camera and device 2 for an external camera. I can live with that but the 
fact that it hangs up if I send the wrong device number is a bit 
worrisome. Any thoughts on what is going wrong here and how I might fix 
this.


Thanks,

Jim

[PD] Clearing pix_delay buffer.

[Jim Ruxton]

I was wondering if there is any way to clear the buffer in Gem's 
pix_delay . If I send video to it a second time the frames of video I 
previously sent to it remain in the buffer. Is there a way to start 
fresh each time I send it video rather than keeping the old video in 
it's buffer. I was hoping to be able to send it a clear message or 
something similar.

Re: [PD] Moving Window to Second Monitor In Ofelia (Jim Ruxton)

[Jim Ruxton]

Thanks Zack,

Would you have any insights as to why version 2.0.0 and 2.0.1 via Deken 
aren't working on Ubuntu 18.04 for me. In the PD console a message shows 
that the external is loaded ok. Only when I load an Ofelia patch the 
objects aren't recognized.


Thanks,

Jim


Hi Jim,

I'm afraid that's not possible with the 1.0.8 version unless you add 
the feature and rebuild the ofelia external yourself.


It will be possible in the 2.0 version and I'm currently working on 
creating help files. However, I should note that the new version will 
not be directly compatible with the previous 1.0 version.


I will try to release the new version as soon as possible.

Best

Hi Zack,

Yes that version works great. It is true that if I load an audio patch 
the audio is sometimes  glitchy . And yes I can fix it by increasing 
delay. Using the testtone audio patch for example going from 25 msec to 
50 msec when running the clonedParticleSystem fixes the glitches. Let me 
know if you want me to do any more tests.

If you search "ofelia" in the Deken, you will see "ofelia-v1.0.4test".
Could you please try this one and see if the graphics show up on the

If it works, could you please try to create any audio object and see 
if you can hear the sound?
In case the audio is too glitchy, please try increasing the delay time

Please let me know how it goes. I would really appreciate your help.

Re: [PD] Installing PDP on Linux using Deken

I tried installing PDP on Ubuntu 17.10 using Deken. The installation seemed
to work well and put the external in the same folder as all the other
externals I have installed. However when I try building a patch with a pdp
object I get the message that the object couldn't be created. Any thoughts
what may be up with this external and why it won't load properly for me. My
path points to it so it isn't that.

These are three different steps:
Installing via Deken
Loading the library eg via creating an object [declare -lib Gem]
Creating objects from that library.

Are you missing the second step perhaps?


Thanks, You are correct I didn't include step 2 but I never have had to 
do this with other externals I installed using Deken. I tried it anyway 
but it made no difference. The object still couldn't be created.

Re: [PD] GEM on Raspberry Pi

Frederico, I'm curious if you just installed PD via a repository on the 
Pi3 or downloaded a special version of PD compiled for the Pi. Did you 
install Gem separately or use a version that came bundled with the PD 
you used ?

Thanks,
Jim

Hello,

I have tried Gem on the Pi3 and it works. I did not try Gem *completely*
because I had no time, but did not encounter major issues other than video
capture. I could not use video capture since it overworked the CPU.
However, accessing the video feed with openCV (not through Gem) gave *very*
reasonable CPU usage (while doing Face Tracking, for example). I am not
sure why I encountered such a difference, but I just couldn't use Gem for
*that*.

Cheers,

Fede

i think this is the wrong question.

Gem on the rpi is kind of limited as it (Gem) depends on openGL and the
rpi provides openGL-ES (though there *are* experimental (still?) drivers
for openGL as well).
this is quite independent of purr data, pd-vanilla or whatever.

Thanks using makefilename along with a save message to pix_buffer in

it combines three unrelated things:

- saving pixes to disk



which alternatives should be

Thanks Etienne, I didn't know about this feature of mplayer. I assume 
this would work across platforms which is great. I'll give it a try.

You could use the -udp-slave option with mplayer, and send the 
timecode from puredata. Just used that to synchronise 6 video players 
and it works pretty well. There was no sound played by mplayer in my 
case but there's no reason it wouldn't work.
The timecode you have to send is just the position in seconds, in 
bytes. For instance if you make a counter, bang it with a metro at 
40ms so you have 25fps counter, then divide by 25 and send through 
moocow any2bytes and udpsend.
If you want to see the timecode mplayer needs, launch one as 
udp-master and connect it to pure data through udpreceive.

Re: [PD] Playing Video with Audio

Thanks Max. It looks like you have assembled a great collection of AV 
patches. I will take a look at them and see what I can use and yes if I 
come up with anything unique I will add it.

Re: [PD] Error Compiling Gem on Ubuntu 15.04

[Jim Ruxton]

I am getting the following errors in compiling Gem on Ubuntu 15.04. Any
thought on what I need to do to correct this. Thanks.

this has been fixed in Gem's git for a long time.

I was having trouble with autoconf so went with the stable version.

but there hasn't been a release for an even longer time.
but if you need to stick with a properly released version of Gem, why
don't you just use the Gem that comes with ubuntu?

as in:
$ sudo apt-get install gem

Thanks for this, the documentation I saw said

which documentation?
can it be fixed?


Sorry I don't remember where I saw this and now that I think of it 
perhaps it didn't say pd-gem specifically but rather to add pd- in front 
of external names when loading them using apt-get. I understand now that 
isn't the case for gem. Thanks again for clarifying this.

Jim

I've always had the same problem (and probably should have issued a bug

Thanks for this, the documentation I saw said

sudo apt-get install pd-gem

which didn't work.  Will definitely go this route next time around now 
that I know  the correct command.
