Jaymie commented on Bodysoulspirit's Bug Report, “Webpage rendering problems

As you noted, problems playing videos and Lottie files in Make Image from Web Page are caused by basically the same underlying problem: limitations with the macOS web browser engine that the node uses to render web pages.

We recently tried a few more experiments in search of a relatively quick fix or workaround. But there really doesn't seem to be one. The node renders the web pages to an offscreen window and then turns the result into an image. There doesn't seem to be any way to trick the browser engine into playing Lottie animations when rendering to an offscreen window.

You asked about outputting an image vs. outputting directly to a window. If literally all you want to do is display the webpage, then you can use the Open URL in Browser node (and Lottie animations will work). In contrast, outputting to an image makes it possible to integrate the image with other Vuo graphics and to interact with the page within Vuo. Outputting directly to a window would not be noticeably faster, since macOS would still be internally rendering to an image that it provides to the window manager.

Coming back to the main question of the bug report — We'd have to investigate further to know just how difficult it would be to get around the limitations currently in the Make Image from Web Page node. Recently we thought of one potential solution, which would be to render the image to a virtual screen rather than an offscreen window, but we'd have to try it and see if it worked. If not, the only solution we know of would be to reimplement the node with a different web browser engine, as I mentioned on the other bug report.

Although the limitations with Make Image from Web Page are arguably a bug rather than a missing feature, the amount of effort required to fix the limitations is more like a feature request than a typical bug report. So if this is important to you, please create a feature request, linking to this bug report, so the community can prioritize it relative to other improvements.

Jaymie commented on Paul's Bug Report, “Crashing with modules composition

Thanks, Paul, for providing a simple setup to reproduce the problem. I confirmed that it's also crashing for me. It crashes consistently if I edit and then immediately quit. It doesn't seem to crash if I wait a few seconds between those steps. We'll add this to our queue of bugs to fix.

I am very grateful to Huseyin for his generosity in sharing his knowledge in this workshop. No doubt intending to develop future projects with Vuo since I am an orphan of Quartz Composer, very happy to be able to resume my studies with visual programming and interactivity. Thanks also to the developers of Vuo.

Thank to this workshop, I returned to visual programming. I started with QuartzComposer around 2008, and since its bitter end, I have been searching for a new language. I knew VUO was the best option for my profile, but I did not really succeed to learn it - until this Workshop. Besides of sharing transparently so much knowledge for such an amplitude of use cases and contexts, and showing/opening so much doors, I really love that Huseyin keeps open the communication in the community through Discord and direct contact. I certainly recommend it, already on the second day after the session I was creating again own patches. Thank you, Huseyin, for your open way, thank you, VUO team, to offer funding. Due to booth, I am finally back creating.

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

Crashing with modules composition

Status: 

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.

Motus Lumina posted a new Composition, “Sand Storm

Sand Storm

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!
