我正在开展一个涉及视频捕捉的项目。我本质上想以编程方式捕获视频。

我定义了imagepicker并开始了视频捕获:

if (UIImagePickerController.isSourceTypeAvailable(.camera)) {
            imagePicker.sourceType = .camera
            imagePicker.cameraDevice = UIImagePickerControllerCameraDevice.front
            imagePicker.allowsEditing = false
            imagePicker.delegate = self

            //present(imagePicker, animated: true, completion: {})
        }
        imagePicker.startVideoCapture()
        print("Capture started")

之后,我停止了视频捕捉:

imagePicker.stopVideoCapture()
    print("capture over")

我知道这应该是我的方法:

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {

    print("captured")


    if let pickedvideo:NSURL = (info[UIImagePickerControllerMediaURL] as! NSURL) {
        let selectorToCall = Selector("videoWasSavedSuccessfully.didFinishSavingWithError:context:")
        UISaveVideoAtPathToSavedPhotosAlbum(pickedvideo.relativePath!, self, selectorToCall, nil)

        let videoasset = (AVAsset(url: pickedvideo as URL))
        let playeritem = AVPlayerItem(asset: videoasset)
        let player = AVPlayer(playerItem: playeritem)
        let playerViewController = AVPlayerViewController()
        playerViewController.player = player
        self.present(playerViewController, animated: true) {
            playerViewController.player?.play()
        }
    }
}

但是“捕获”不会被打印,即使我知道我正在开始并停止录制,因为“Capture started”和“Capture over”都会打印出来。我不确定为什么没有调用该方法。有什么建议吗?

尝试将mediaTypes设置为kUTTypeMovie。
