AVCaptureMultipeerVideoDataOutput 0.0.1

Maintained by PJ Gray.

You want to add pod 'AVCaptureMultipeerVideoDataOutput', '~> 0.0' similar to the following to your Podfile:

target 'MyApp' do
  pod 'AVCaptureMultipeerVideoDataOutput', '~> 0.0'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try AVCaptureMultipeerVideoDataOutput

Advertises one stream of video over a multipeer connection.

Use SGSMultipeerVideoMixer for an example of how to view.

Details

Multipeer connection stuff is abstracted inside an AVCaptureVideoDataOutput subclass so setup is easy using the normal AV pipeline:

    // Create the AVCaptureSession
    self.captureSession = [[AVCaptureSession alloc] init];

    // Setup the preview view
    AVCaptureVideoPreviewLayer *captureVideoPreviewLayer = [AVCaptureVideoPreviewLayer layerWithSession:self.captureSession];
    captureVideoPreviewLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;
    captureVideoPreviewLayer.frame = CGRectMake(0,0, 320, 320);
    [self.previewView.layer addSublayer:captureVideoPreviewLayer];

    // Create video device input
    AVCaptureDevice *videoDevice = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
    AVCaptureDeviceInput *videoDeviceInput = [AVCaptureDeviceInput deviceInputWithDevice:videoDevice error:nil];
    [self.captureSession addInput:videoDeviceInput];

    // Create output
    AVCaptureMultipeerVideoDataOutput *multipeerVideoOutput = [[AVCaptureMultipeerVideoDataOutput alloc] initWithDisplayName:[[UIDevice currentDevice] name]];
    [self.captureSession addOutput:multipeerVideoOutput];

    [self.captureSession startRunning];

Thats it! Look in the AVCaptureMultipeerVideoDataOutput class for details on how it sends the data. (The data sent ends up being a fairly low quality JPEG).

Setup

Uses cocoapods, so just add to your Podfile

pod "AVCaptureMultipeerVideoDataOutput"

See the Sample project for an example implementation. To run the sample:

pod install

Then open 'MultipeerVideoOutputSample.xcworkspace'

To Do

Expose more of the output format variables
