Vuo version: 

OS version: 

  • macOS 10.14

Steps causing the bug to occur: 

In macOS 10.14.4, compositions with a Receive Live Video or List Video Devices node no longer work and sometimes crash.

The underlying problem is that, starting in macOS 10.14.4, a video library that Vuo uses (Appleā€™s QTKit) is broken. Other apps that use QTKit have also stopped working.

The problem will be fixed in Vuo 2.0, as it no longer relies on QTKit. See our mailing list / blog for updates on the estimated release date.

Have you found a workaround?: 

Downgrade to macOS 10.14.3 or earlier.


What do we do in the meantime

OSX 10.14.3? That requires a complete reinstall of OSX right?

I might have a work around for my project using a 2nd Blackmagic UltraStudio Mini Recorder so I don't have to use the Receive Video Node but at the moment I'm having a weird conflicting issue were frames from the one Blackmagic device enter and disrupt the image of the other (along with some green flashes and lines). I didn't get this when the other camera was a webcam on the Receive Live Video node. Still testing because when I make a simple composition with both Blackmagic capture devices I haven't seen the issue yet. Both cameras are running at the same frame rate in this test so it's not the exact issue I reported before I don't think.
