嗨,我按照Jared Davidson的课程创建了一个自定义相机视图,并使用AVFoundation保存图片。
https://www.youtube.com/watch?v=w0O3ZGUS3pk然而,我想录制和保存视频而不是图片。有人可以帮助我吗?我确定这很简单,但苹果的文档是用Objective-C编写的,我无法解读它。
这是我的代码。谢谢。
import UIKit
import AVFoundation
class ViewController: UIViewController {
var captureSession = AVCaptureSession()
var sessionOutput = AVCaptureStillImageOutput()
var previewLayer = AVCaptureVideoPreviewLayer()
@IBOutlet var cameraView: UIView!
override func viewWillAppear(animated: Bool) {
let devices = AVCaptureDevice.devicesWithMediaType(AVMediaTypeVideo)
for device in devices {
if device.position == AVCaptureDevicePosition.Front{
do{
let input = try AVCaptureDeviceInput(device: device as! AVCaptureDevice)
if captureSession.canAddInput(input){
captureSession.addInput(input)
sessionOutput.outputSettings = [AVVideoCodecKey : AVVideoCodecJPEG]
if captureSession.canAddOutput(sessionOutput){
captureSession.addOutput(sessionOutput)
captureSession.startRunning()
previewLayer = AVCaptureVideoPreviewLayer(session: captureSession)
previewLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
previewLayer.connection.videoOrientation = AVCaptureVideoOrientation.Portrait
cameraView.layer.addSublayer(previewLayer)
previewLayer.position = CGPoint(x: self.cameraView.frame.width / 2, y: self.cameraView.frame.height / 2)
previewLayer.bounds = cameraView.frame
}
}
}
catch{
print("Error")
}
}
}
}
@IBAction func TakePhoto(sender: AnyObject) {
if let videoConnection = sessionOutput.connectionWithMediaType(AVMediaTypeVideo){
sessionOutput.captureStillImageAsynchronouslyFromConnection(videoConnection, completionHandler: {
buffer, error in
let imageData = AVCaptureStillImageOutput.jpegStillImageNSDataRepresentation(buffer)
UIImageWriteToSavedPhotosAlbum(UIImage(data: imageData)!, nil, nil, nil)
})
}
}
}
didFinishRecordingToOutputFileAtURL
代理方法调用UISaveVideoAtPathToSavedPhotosAlbum()
来将视频保存到照片库中。如果您的问题得到解答,请接受此答案。 - Rhythmic Fistman
