Are you using the recently added IOAudioMonitor feature? Does this crash occur when the stream.loopback=false?
yes it's using loopback, however not sure if it's true or false when the crash occurs. Feature implemented as in example app.
Can it be fixed or is it better to remove the feature?
Thank you for using the feature I recently implemented so promptly.
I suspect that the crash is occurring when the RTMPStream instance is being disposed of with loopback = true. I believe the crash could be avoided by setting loopback = false before rtmpStream setting null.
I will try to implement the fix.
