Crash: Make audio frame with more channels than Save Frame to Movie expects

Steps causing the bug to occur

  1. Make Audio frame that has (say) 5 channels
  2. Connect Make Audio Frame to Save Frames to Movie
  3. Vuo Crashes
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[AVAssetWriterInput initWithMediaType:outputSettings:sourceFormatHint:] AudioChannelLayout channel count does not match AVNumberOfChannelsKey channel count'
abort() called
terminating with uncaught exception of type NSException

Have you found a workaround?

Not sure yet

Other notes

  • Vuo version: 2.3.2
  • macOS version: macOS 11
  • CPU: arm64
  • How severely does this bug affect you? It’s annoying but I can work around it.

We were able to reproduce this and are working on a fix to allow multi-channel audio for this situation.

Fixed in Vuo 2.4.0.
