Possible 'Receive Blackmagic Video' Node issue

Status: 

Vuo version: 

Fixed in Vuo version: 

OS version: 

  • macOS 10.14

How severely does this bug affect you?: 

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

Steps causing the bug to occur: 

On an extremely complex composition that I can't unfortunatly post I couldn't get 2 Receive Blackmagic Video nodes using 2 Blackmagic UltraStudio Mini Recorders to work in the same composition properly. Watch link below to see an example of the issue. Each BM UltraStudio Mini Recorder has it's own address and can be used in OBS together and usually worked in a much simpler Vuo composition but has issues in the complex composition. What's even stranger is that swapping the BM node out of the receive live video node fixes the issue with nothing else changed so this has to be an issue with the BM node itself I think. Right?

I have tried to create a simpler composition showing the issue but only ran across the issue one other time. However after a reload of that project it started working properly and I wasn't able to recreate the issue on that project again.

Have you found a workaround?: 

Make sure you are using MacOS 10.14.3 or earlier. With nothing else changed I replaced one of the Receive Blackmagic Video nodes for a Receive Live Video node and this resolved the issue.

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.
