播放录制的AVCapture格式的内容

Question

我正在尝试播放录制的会议后，它是记录器的完整视图。有点像"snapchat“

我可以在UIView中录制和播放视频播放，但它是通过“播放”、“完成”和“停止”按钮显示的。我不想这样。我希望它看起来像snapchat。

这是我的代码，我在其中找到了Here，但我做了一点修改。:)

import UIKit
import AVFoundation
import AssetsLibrary
import Photos
import MediaPlayer
import AVKit

class Camera: UIViewController, AVCaptureFileOutputRecordingDelegate {


@IBOutlet var cameraView: UIView!
var previewLayer : AVCaptureVideoPreviewLayer?
var captureDevice:AVCaptureDevice!
var CamChoser = false

var moviePlayer: MPMoviePlayerController?
@IBOutlet weak var playback: UIView!

@IBOutlet weak var exitCameraModeButton: UIButton!
@IBAction func exitCameraModeButton(sender: AnyObject) {
    self.dismissViewControllerAnimated(true, completion: nil)
}


var captureSession = AVCaptureSession()

lazy var cameraDevice: AVCaptureDevice? = {
    let devices = AVCaptureDevice.devicesWithMediaType(AVMediaTypeVideo) as! [AVCaptureDevice]
    return devices.filter{$0.position == .Front}.first
}()

lazy var micDevice: AVCaptureDevice? = {
    return AVCaptureDevice.defaultDeviceWithMediaType(AVMediaTypeAudio)
}()

var movieOutput = AVCaptureMovieFileOutput()

private var tempFilePath: NSURL = {

    let tempPath = NSURL(fileURLWithPath: NSTemporaryDirectory()).URLByAppendingPathComponent("tempMovie").URLByAppendingPathExtension("mp4").absoluteString
    if NSFileManager.defaultManager().fileExistsAtPath(tempPath) {
        do {
            try NSFileManager.defaultManager().removeItemAtPath(tempPath)
        } catch { }
    }
    return NSURL(string: tempPath)!
}()

private var library = ALAssetsLibrary()
//private var library = PHPhotoLibrary()

@IBOutlet weak var switchCameraButton: UIButton!
@IBAction func switchCameraButton(sender: AnyObject) {
    //startSession()

override func viewDidLoad() {
    super.viewDidLoad()

    //start session configuration

    captureSession.beginConfiguration()
    captureSession.sessionPreset = AVCaptureSessionPresetHigh

    let devices = AVCaptureDevice.devices()
    startSession()
}

func startSession() {

    // add device inputs (front camera and mic)
    print(CamChoser)

        captureSession.addInput(deviceInputFromDevice(cameraDevice))
        captureSession.addInput(deviceInputFromDevice(micDevice))

        // add output movieFileOutput
        movieOutput.movieFragmentInterval = kCMTimeInvalid
        captureSession.addOutput(movieOutput)

        // start session
        captureSession.commitConfiguration()
        previewLayer = AVCaptureVideoPreviewLayer(session: captureSession)
        self.cameraView.layer.addSublayer(previewLayer!)

        self.cameraView.bringSubviewToFront(self.switchCameraButton)
        previewLayer?.frame = self.cameraView.layer.frame
        captureSession.startRunning()
}

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
    print("touch")
    // start capture

    movieOutput.startRecordingToOutputFileURL(tempFilePath, recordingDelegate: self)

}

override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
    print("release")
    //stop capture
    movieOutput.stopRecording()

    let videoUrl = movieOutput.outputFileURL
    moviePlayer = MPMoviePlayerController(contentURL: videoUrl)
    moviePlayer!.movieSourceType = MPMovieSourceType.Unknown

    playback.addSubview((moviePlayer?.view)!)
    //moviePlayer!.prepareToPlay()
    moviePlayer?.setFullscreen(true, animated: true)
    moviePlayer!.play()
    cameraView.bringSubviewToFront(playback)




}

private func deviceInputFromDevice(device: AVCaptureDevice?) -> AVCaptureDeviceInput? {
    guard let validDevice = device else { return nil }
    do {
        return try AVCaptureDeviceInput(device: validDevice)
    } catch let outError {
        print("Device setup error occured \(outError)")
        return nil
    }
}

func captureOutput(captureOutput: AVCaptureFileOutput!, didStartRecordingToOutputFileAtURL fileURL: NSURL!, fromConnections connections: [AnyObject]!) {
}

func captureOutput(captureOutput: AVCaptureFileOutput!, didFinishRecordingToOutputFileAtURL outputFileURL: NSURL!, fromConnections connections: [AnyObject]!, error: NSError!) {
    if (error != nil) {
        print("Unable to save video to the iPhone  \(error.localizedDescription)")
    } else {
        // save video to photo album
        library.writeVideoAtPathToSavedPhotosAlbum(outputFileURL, completionBlock: { (assetURL: NSURL?, error: NSError?) -> Void in
            if (error != nil) {
                print("Unable to save video to the iPhone \(error!.localizedDescription)")
            }
        })

    }

}

}

只想让你知道，iOS 9已经弃用了MPMoviePlayerController。问题是你的控件样式设置为embedded，默认情况下，它显示控件按钮。使用MPMovieControleStyle.None删除控件。
