COULDN T GET SOUND BUFFER STATUS BLUETOOTH

TimingInfo.presentationTimeStamp = presentationStamp Deep Copy of CMImageBuffer or CVImageBufferД«ut none of them helps me to use correctly CMSampleBufferCreate function with 12 parameters: CMSampleBufferRef copyBuffer Д¬MBlockBufferRef data = CMSampleBufferGetDataBuffer(sampleBuffer) Д¬MFormatDescriptionRef formatDescription = CMSampleBufferGetFormatDescription(sampleBuffer) Д¬MItemCount itemCount = CMSampleBufferGetNumSamples(sampleBuffer) Д¬MTime duration = CMSampleBufferGetDuration(sampleBuffer) Д¬MTime presentationStamp = CMSampleBufferGetPresentationTimeStamp(sampleBuffer).

Creating copy of CMSampleBuffer in Swift returns OSStatus -12743 (Invalid Media Format).

Pulling data from a CMSampleBuffer in order to create a deep copy.

There are few related questions were asked on SO: I also know that CMSampleBufferCreateCopy only creates shallow copies. Obviously, I need to create deep copies of incoming buffers for further processing. The problem I am having is that my frames coming from delegate method captureOutput:didOutputSampleBuffer:fromConnection: being dropped after I retain them in CFArray for long time.

And I am not getting any errors in both cases. It only works when I run the bluealsa-aplay command from the terminal. I am trying to manually setup my raspberry pi 4 as a Bluetooth audio receiver, but there is no sound playback when I start the bluealsa-aplay service I created.
