How to play audio sample buffers from AVCaptureAudioDataOutput

Question

The main goal of the app Im trying to make is a peer-to-peer video streaming. (Sort of like FaceTime using bluetooth/WiFi).

Using AVFoundation, I was able to capture

Answer 1

To show video you can use (here is : getting of ARGB picture and converting to Qt (nokia qt) QImage you can replace by other image)

place it to delegate class

 - (void)captureOutput:(AVCaptureOutput *)captureOutput
    didOutputSampleBuffer:(CMSampleBufferRef)sampleBuffer
           fromConnection:(AVCaptureConnection *)connection

NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];

CVImageBufferRef imageBuffer = CMSampleBufferGetImageBuffer(sampleBuffer);

CVPixelBufferLockBaseAddress(imageBuffer,0);

SVideoSample sample;

sample.pImage      = (char *)CVPixelBufferGetBaseAddress(imageBuffer);
sample.bytesPerRow = CVPixelBufferGetBytesPerRow(imageBuffer);
sample.width       = CVPixelBufferGetWidth(imageBuffer);
sample.height      = CVPixelBufferGetHeight(imageBuffer);

QImage img((unsigned char *)sample.pImage, sample.width, sample.height, sample.bytesPerRow, QImage::Format_ARGB32);

self->m_receiver->eventReceived(img);

CVPixelBufferUnlockBaseAddress(imageBuffer,0);
[pool drain];
