Could it be that the VuoRenderedLayers_update function is computationally expensive to run with UI nodes and arrange nodes? Or that it somehow returns the renderingDimensionsChanged as true when using UI elements?

That is a good chapter title! 😅 The bytes are still little-endian, you just need to use the 4-byte conversion instead of the 2-byte conversion.

Had this happen again today. Only similarity I can think of is having used NDI scan converter. To be able to quit this time I had to open a composition then the Quit option was available again.

Arrange layers tanks performance when window port is connected using UI layers

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. Open and run attached composition
  2. Observe somewhat sluggish but usable behavior (might be related to text usage or the Mac it's being run on)
  3. Open sub-composition
  4. Attach Window input port to Window port of arrange node
  5. Start main composition
  6. Observe slow/unusable behavior
  7. Looking at the event flow the arrange node fires events constantly

Have you found a workaround?: 

Don't attach window cable to arrange node

Other notes: 

I assume the arrange nodes aren't optimized for using them with UI layers (which they are super-useful for). Having an option to "Allow changes" for the Window port type could perhaps solve this?

Thanks for the feedback! I don't always write simple/clear enough so it's golden to get something like that to iron out the wrinkles. Vuo has a build in data to image node, but I'll see about examples for other uses. The tutorial should possibly be split into chapters as well to give more bite-sized approaches to it, the full thing can take some time to get through.

With 32-bit files, you need to take the byte count more into consideration as you have 4 bytes per sample. I didn't write much about automating this from the header data as it would get even longer (chaptering it out might be a way to include it). You can divide the byte-rate by the sample rate to get the bytes per sample, and use that output to set the Comb List pick/skip count.

Having more chunks means you'll also have to offset the start of the read to 45 + the bytes of the additional chunks. Ideally there would be a "Find in Data" node (or something like that) for scanning the file and provide the byte location of the "DATA" chunk-ID. Then you'd be able to use that to get to the starting point relatively easy. For now I think it will have to be a manual process though.
