Turns out I ended up having to go a different route after all. The Select Latest node was working great for my test still images but as soon as I got into video sources it was no longer suitable for selecting my sources (since video is a steady stream of images it's always being chosen as the Latest source). However I ended up using the 8 input Select Latest to output the number of the source on my Select Input node and used combination of compare numbers, math node and a True/False node to split the output to the proper Select Input node. Seems to be working well now.

I was even able to make a "Take" button along with a "Dissolve" and "Cut" button to select what transition type I wanted between the current video source and the one coming in. Super smooth transitions and live video even at 3360x1080 resolution output!!! Amazing!

Receive Live Video node- Start/Stop not working properly

Status: 

Vuo version: 

Fixed in Vuo version: 

OS version: 

  • macOS 10.12

How severely does this bug affect you?: 

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

Steps causing the bug to occur: 

  1. Connect Receive Live Video node to Render Image to Window node
  2. Connect Fire on Start node to Start port on Receive Live Video node.
  3. Run Composition and on the Receive Live Video mode Right Click on Stop port and Fire Event.
  4. Now try and start the video again with the Start port... it won't start. Or am I doing something wrong?

Have you found a workaround?: 

No

Other notes: 

I'm trying to disable this node for 2 video seperate input devices when the composition doesn't require them but I can't and once it's stopped it won't start again unless I close and restart the composition.

I ended up using the 8-input Select Latest 2-input Select Latest nodes as well... but came up with a ridiculously convoluted way of using a bazillion more nodes to get the exact same result... your way is SO much more elegant!

I thank-you for pointing out how much I was overthinking this... I keep forgetting you can hold down Option and strip out data to just leave it an event and use it to trigger just about anything.

Select Input Node... How do I do 16 inputs properly???

OK, I'm running into an issue I can't quite seem to figure out, it may just be that I'm stuck on the way I used to do it in QC with the Multiplexer node where I could pick as many inputs as I needed. Here's the situation, I have 16 buttons on a touch screen, the plan is for each button to trigger an image (composite image) or video to display on another screen. In QC I would have just made each button trigger the corresponding Source Index value of a 16 channel multiplexer and just send the output to the proper billboard.
