AVFoundation.AVAudioSourceNodeRenderHandler delegate is incorrectly bound, causing a crash when it is used as a parameter to AVAudioSourceNode constructor #9538

Closed KumarKodali closed 4 years ago

KumarKodali commented 4 years ago

Steps to Reproduce

  1. Create an instance of AVAudioSourceNode with AVAudioSourceNodeRenderHandler call back
  2. Connect to AudioEngine's OutputNode using OutputNode's Bus 0 InputFormat
  3. Start AudioEngine

Expected Behavior

AVAudioSourceNodeRenderHandler delegate should be called for audio buffers.

Also, shouldn't AVAudioSourceNodeRenderHandler's isSilence parameter be a reference as AVAudioSourceNodeRenderBlock's isSilence parameter is a pointer to BOOL?

public delegate int AVAudioSourceNodeRenderHandler (bool isSilence, AudioTimeStamp timestamp, uint frameCunt, ref AudioBuffers outputData);

typedef OSStatus (^AVAudioSourceNodeRenderBlock)(BOOL *isSilence, const AudioTimeStamp *timestamp, AVAudioFrameCount frameCount, AudioBufferList *outputData);

Actual Behavior

================================================================= Native Crash Reporting

Got a segv while executing native code. This usually indicates a fatal error in the mono runtime or one of the native libraries used by your application.

@KumarKodali Thank you for your feedback! We were able to reproduce this locally and are working on a fix (you can see the linked PR above).

@whitneyschmidt Thank you for taking time to look into this. I would also like to add that it also crashes in WatchOS 6.0+ as well.
