ios – Is it doable to set most popular pattern buffer measurement for AVCaptureOutput?

[ad_1]

Say we have now an AVCaptureAudioDataOutput object that has been arrange with an AVCaptureSession to get information samples from the system’s microphone.

captureOutput(_:didOutput:from:) in AVCaptureAudioDataOutputSampleBufferDelegate all the time will get referred to as with 2048 bytes of samples. Is it doable to set a most popular pattern buffer measurement?

A fundamental instance:

let output = AVCaptureAudioDataOutput()
output.setSampleBufferDelegate(delegate, queue)
// Add output to AVCaptureSession and begin the seize session as soon as every part is about up
...

// Within the delegate
public func captureOutput(_ output: AVCaptureOutput, 
                          didOutput sampleBuffer: CMSampleBuffer, 
                          from connection: AVCaptureConnection) {
    // sampleBuffer is 2048 bytes, however I need much less
    let blockBuffer = CMSampleBufferGetDataBuffer(sampleBuffer)
    print(CMBlockBufferGetDataLength(blockBuffer!)) // 2048
    ...
}
