Paul posted a new Bug Report, “Crashing with modules composition

Crashing with modules composition


Vuo version: 

OS version: 

  • macOS 12

CPU architecture: 

Intel x86_64

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 a composition with a modules based subcomposition, example attached.
  2. Double click on the subcomposition, "A_sub" in this example.
  3. Make some cosmetic changes, like shifting nodes around.
  4. Quit, choose Save
  5. Vuo will invariably (although not every time) crash.

Have you been able to reproduce the problem?: 

●●● — Yes, the problem occurs consistently when I follow the steps above

Have you found a workaround?: 

Yes. Save and close subcomposition window first.

Sand Storm / Vuo Composition

Vuo composition made with Make Noise Image, Ripple Directionally, and Blend Image with Feedback Nodes. Also, I used Edges and Exposure Adjust FX from VDMX Effects Library.

There was a problem exporting this composition as FFGL but it works perfectly as a Protocol Composition and Mac App.

Looking forward to hearing your feedback!

Composition and supporting files:

Vector graphics would be one way to implement Lottie support, but would require significant groundwork including this other feature request.

To decouple the current feature request so it doesn't depend on others, we could instead render Lottie animations to images. Perhaps a node like Play Lottie animation that outputs a series of images, similar to Play Movie or Decode Movie Image.

I'm opening the feature request for voting with the assumption that it's for rendering to images. (If the feature request is still open by the time Vuo supports vector paths and SVG files, we can reevaluate the plan for implementation.)

A further assumption is that we'd build the node on top of an open-source cross-platform Lottie player. Tentatively, rlottie seems like the best available option. It implements many though not all of the After Effects bodymovin features.

Workaround for playing Lottie files in Vuo now: convert them to GIFs.

Jaymie commented on Marc's Discussion, “Creating own nodes with OpenCV

Yes! Here's a very simple example as a starting point: OpenCV_test.zip

Feel free to ask further questions as you work on the nodes. Here are some previous discussions that might be helpful:
