    Paul commented on VJ SATOSHI's Bug Report, “"export app" clash

    I just had the same problem. Crashes on app export in 2.3, fine in 2.2.1. Yes, the compositionI was exporting has one subcomposition. I tried export with another composition that didn't have any subcompositions and it worked.

    Paul posted a new Bug Report, “USB camera ... no image

    USB camera ... no image

    Status: 

    Vuo version: 

    OS version: 

    • macOS 10.15

    How severely does this bug affect you?: 

    ●●●○ — It prevents me from completing a specific task with Vuo.

    Steps causing the bug to occur: 

    1. No image from USB camera.

    Have you found a workaround?: 

    No

    Other notes: 

    I have UC80MPA USB video camera from Spinel. https://www.spinelelectronics.com/pdf/UC80MPA%20Specification.pdf It registers itself correctly "8M USB Camera". Works in Skpye, for example. But I don't get an image in Vuo. Tested in version 2.3 and 2.2.1 Ideas?

    Limitation on "Execute Shell Command"

    I was hoping to use gphoto2 to capture images from a DLSR camera. I imagined using "Execute Shell Command" node to do this, however I get the following error

    "dyld: Library not loaded: /opt/local/lib/libgphoto2.6.dylib Referenced from: /opt/local/bin/gphoto2 Reason: no suitable image found. Did find: /opt/local/lib/libgphoto2.6.dylib: file system sandbox blocked stat()

    I imagine this is some security limitation. Any way around it, noting of course that the command I'm using works in the Terminal.

    Paul commented on Paul's Discussion, “ARM native

    Great to hear. I have an exhibition coming up in a few months and the two iDomes are driven by a Vuo composiiton on a MacMini., latest before the M1 They are relatively simple: read an h264/265 equirectangular movie, extract a fisheye (my shader) dependig on user navigation, warp that frame using the mesh warping for the projection. It all runs smooth for 4K equirectangular movies but the projection system is capable of a bit higher resolution. Is the new version of Vuo on the M1 likely to improve such a Vuo composiiton. ps: I won't "hold" you to your answer, just trying get some opinions and ascertain whether I should do the test.

    Thanks, works a treat. But I must have missed that opportunity in Vuo, I'm a programmer and can handle this ... where is it documented? What are the performance issues of these C based modules vs what I assume are more normal compiled ones?
