SIGABORT with ExtAudioFileWrite and .m4a file

Hi,

I am getting into a trap. Please check stack-trace, howto fix this?

regards, Joël

Hi Joël,

It's unclear from the stack trace whether the problem is occurring due to something about the audio formats involved, the sizes of the audio frames being converted and written, or due to some internal issue in ExtAudioFile or AudioConverter. Either way, it should not be crashing like that, and we'd appreciate the opportunity to investigate further.

Please file a report via http://feedbackassistant.apple.com so that we can collect more information about the issue and investigate it with the best chance of success.

When filing the report, it would be very helpful to:

  • Select "Developer Technologies & SDKs" for where to start the feedback.
  • For "Which technology does your report involve", select "Core Audio".
  • Include a link to this forum thread.
  • Collect and attach a sysdiagnose (see https://developer.apple.com/bug-reporting/profiles-and-logs/) or at the very least the full crash report (.ips file)
  • If possible, supply the source code for a minimal example small program demonstrating the issue; this would allow us to quickly reproduce the issue and troubleshoot on our end.
  • If including an example program is not practical, please try to provide as much context as possible; for example: the exact audio formats involved (the values of the AudioStreamBasicDescription structures provided to ExtAudioFileCreateWithURL() and/or set via the kExtAudioFileProperty_FileDataFormat and kExtAudioFileProperty_ClientDataFormat properties with ExtAudioFileSetProperty()) and the parameters passed to ExtAudioFileWrite() when the crash occurred, if known.

Thanks, - rhymu
