Title Body

I've been trying to write a video+audio using AVAssetWriter and AVAssetWriterInputs. I read multiple posts in this forum of people saying they were able to accomplish that, but it is not working for me. If I just write video then the code is doing its job very well. When I add audio the output file is corrupted and cannot be reproduced. Here is part of my code: Setting up AVCaptureVideoDataOutput and AVCaptureAudioDataOutput: NSError *error = nil; // Setup the video input AVCaptureDevice *videoDevice = [AVCaptureDevice defaultDeviceWithMediaType: AVMediaTypeVideo]; // Create a device input with the device and add it to the session. AVCaptureDeviceInput *videoInput = [AVCaptureDeviceInput deviceInputWithDevice:videoDevice error:&error]; // Setup the video output _videoOutput = [[AVCaptureVideoDataOutput alloc] init]; _videoOutput.alwaysDiscardsLateVideoFrames = NO; _videoOutput.videoSettings = [NSDictionary dictionaryWithObject: [NSNumber numberWithInt:kCVPixelFormatType_32BGRA] forKey:(id)kCVPixelBufferPixelFormatTypeKey]; // Setup the audio input AVCaptureDevice *audioDevice = [AVCaptureDevice defaultDeviceWithMediaType: AVMediaTypeAudio]; AVCaptureDeviceInput *audioInput = [AVCaptureDeviceInput deviceInputWithDevice:audioDevice error:&error ]; // Setup the audio output _audioOutput = [[AVCaptureAudioDataOutput alloc] init]; // Create the session _capSession = [[AVCaptureSession alloc] init]; [_capSession addInput:videoInput]; [_capSession addInput:audioInput]; [_capSession addOutput:_videoOutput]; [_capSession addOutput:_audioOutput]; _capSession.sessionPreset = AVCaptureSessionPresetLow; // Setup the queue dispatch_queue_t queue = dispatch_queue_create("MyQueue", NULL); [_videoOutput setSampleBufferDelegate:self queue:queue]; [_audioOutput setSampleBufferDelegate:self queue:queue]; dispatch_release(queue); Setting up AVAssetWriter and associating both audio and video AVAs
