Which macOS version are you on ?
Tried loading the same example file and they didn't launch for me either.
Checking the images in the Desktop Pictures folder, Apple uses .heic now in macOS Ventura.

Using another folder with .jpeg files the example composition works.
So must be Vuo that doesn't recognize .heic files.

External library woes


I'm struggling a bit with getting the linker going in a nodeset as far as I understand.

The nodes compile fine without complaint from both Clang and GCC until I run them in Vuo. Then i get an error:

Undefined symbols for architecture x86_64: "_ffclos", referenced from: _display_fits_image in composite...

... clang: error: linker command failed with exit code 1 (use -v to see invocation)

Found a workaround by exporting from realtime composition using a generated fake time with counter that I use as timestamp for frames which I store to a movie file. The generated file is perfectly clean. Still would be grateful if I could prevent this workaround.

Process list Example composition not fetching the image urls…

Trying to remember how to create my own data lists (dynamically using starting integers, required list length and some random dynamics).

Loaded the example composition for Process List titled "Display Grid of Images", the composition gets the urls of sample images in the macOS Library/User Pictures/… folder and sub-folders., well it's supposed to but its an empty list every time

texture mapping errors on movie export

sinemod's picture


Vuo version: 

OS version: 

  • macOS 12

CPU architecture: 

Intel x86_64

How severely does this bug affect you?: 

●●○○ — It's annoying but I can work around it.

Steps causing the bug to occur: 

  1. image generator protocol - 3d scene with multiple rotating sphere objects with image textures
  2. export movie

Every xth frame the texture will not be mapped correctly causing artefacts in video.

The issue only occurs when exporting a movie, not when playing realtime.

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. I changed the composition to run realtime and created a fake time with count storing frames to video file. The created file is clean.

Other notes: 

also created a discussion item around this:

Jaymie commented on Paul's Bug Report, “Movie playback and audio issue

We can suggest a workaround. Vuo chooses one of two libraries — Apple AV Foundation or FFmpeg — to play a given movie, depending on the movie's encoding and the Play Movie node's Optimization setting. The bug only happens when using AV Foundation. So you can avoid it by convincing Vuo to use FFmpeg instead —

  • Set the Play Movie node's Optimization input to Random.
  • If this fixes the problem, great, you're done. Otherwise, check Vuo's console (Tools > Show Console) for a message saying that AV Foundation was chosen to play the movie ("Using AvFoundation video decoder despite optimization preference"). This is just to make sure you're on the right track for the workaround. (If instead it says that FFmpeg was used, let us know; that means there's some other bug. )
  • Convert the movie to a format that Vuo's FFmpeg player can read, such as HEVC video + AAC audio.
  • Run the composition again with the converted movie (and Optimization still set to Random). The movie should now play with FFmpeg and you should not encounter the audio bug.

The cause of the bug seems to be that, when you fast-forward the movie, AV Foundation's audio and video streams get out of sync. When you resume normal speed, the audio from the segment you fast-forwarded through should have been discarded, but it gets queued up and played. We plan to fix the bug in an upcoming release.

Scene object texture mapping errors in single frames when exporting movie

sinemod's picture

I have an issue with an image generator composition containing the planetary system. Basically some textured spheres rotating around themselves and orbiting a centered sphere (the sun ;). When running live it looks fine, but in exported movies repeatedly single frames show mismapped textures (most affected are earth and saturn rings). I tried data hold, but it didn't solve the problem.

Did anyone encounter similar problems with textures? Do you have an idea how this could be improved? I'm stuck.
