Oh right! I was a little confused by mic's comment I guess. OS X 10.4.6 was quite a while ago!

Okay, that makes sense. I just went ahead and upgraded to Pro and the beta, so hopefully I'll have better luck now. Thanks so much again for the help!

VUO and QLab4 . . .

Hello VUO team,

Thank you for all your great work on Version 2. I'm enjoying all the improvements.

One of the most popular programs for delivering sound/projections/lighting for live performance is QLab4. QLab has always offered the option of using a custom patch from Quartz Composer to manipulate images. However, the requirement are as follows:

(Your custom composition must publish an input named "_protocolInput_Image" and an output named "_protocolOutput_Image".)

Vuo is Mac only for now, Linux and Windows versions are still on the roadmap.

If you got errors for Render Scene and Draggable Camera it should mean you're using Vuo 1.2.8, sorry, my uploaded version was for Vuo 2 beta.

Although I get no crash using your composition both in Vuo 1.2.8 or Vuo 2, I couldn't get the shader to work in Vuo 1.2.8 by quick testing. Going to work now, will check it later again, but even when you set a shader on the parent node, and feed a shader into the sub-composition for one of the cube sides, for me the sub-composition still says "no shader".
In Vuo 2, how the events flow through sub-compositions have changed, and there it works.

I switched the true / false input selector though in the sub-composition, as I understand you wanted to display a wireframe shader if no other shader is provided ? (see screenshot, all sides except front has color shader, front has wireframe)

Will check later

Thank you both for testing it!

Bodysoulspirit Hmm, okay. Modified version of the node works okay, although the default shader switches don't seem to work now. What did you change? Both the "draggable camera" node and the "render scene to window" nodes in your example composition didn't match up to the versions in my library, and Vuo registered them as missing. Different versions of Vuo perhaps?

Also worth noting, I'm on Mac for whatever difference that makes.

That explains why we couldn't reproduce it :) Thanks for letting us know the results of your investigation.

More investigations led me to understand that it was a Epoccam related issue. After installing the driver, the virtual camera didn't show in available devices, even if it was considered the default camera. Rebooting made it appear, and now it's consisitent. Please close this bug report as it's not a Vuo bug.

Would be great if find faces output the coordinates for the eyes and mouth, or even a rotational value for the face. Could this be possible?

default video input device not found


Vuo version: 

OS version: 

  • macOS 10.14

How severely does this bug affect you?: 

●○○○ — Not much; I'm just letting you know about it.

Steps causing the bug to occur: 

  1. open FindBarCodeInImage example and run
  2. I'd expect Vuo used my only connected webcam (macbook facetime camera) but id doesn't

Have you found a workaround?: 

choose "apple inc facetime hd camera" specific device in "receive live video" node

No crash here, too. Vuo beta 4 on 10.4.6
