swift - AvPlayer 无法从自定义路径播放视频

Question

我正在尝试播放我在此路径中录制的视频。但是我无法从这条路径播放视频。我该怎么办？

let pathMovie = (NSHomeDirectory() as NSString).stringByAppendingPathComponent("Documents/Movie.mp4")

        let fileUrl = NSURL(fileURLWithPath: pathMovie)
        self.videoFrame = view.frame
        self.fillMode = .ResizeAspectFill
        self.alwaysRepeat = true
        self.sound = true
        self.startTime = 0.0
        self.alpha = 1
        self.backgroundColor = UIColor.blackColor()
        self.contentURL = fileUrl

这是我得到的错误。

Failed: Optional(Error Domain=AVFoundationErrorDomain Code=-11800 "The operation could not be completed" UserInfo={NSLocalizedFailureReason=An unknown error occurred (-12893), NSLocalizedDescription=The operation could not be completed, NSURL=file:///var/mobile/Containers/Data/Application/.....-...-...-....-..../Documents/Movie.mp4, NSUnderlyingError=0x150a38e80 {Error Domain=NSOSStatusErrorDomain Code=-12893 "(null)"}})

您可以通过添加以下两种方法从自定义路径播放视频:

注意:请将您的视频名称作为参数传递给 getCustomVideoPath 方法。

swift 4

func getCustomVideoPath(name: String) -> String {
    let strDocumentDirectory = self.getDocumentDirectoryPath()
    return "\(strDocumentDirectory)/\(name).mp4"
}

func getDocumentDirectoryPath() -> String {
    let arrPaths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
    return arrPaths[0]
}

//----------------------------------------------------------------

func playCustomVideo() {
    let strVideoPath = self.getCustomVideoPath(name:"Movie")
    let urlVideoPath = URL(fileURLWithPath: strVideoPath)
    let newPlayerItem = AVPlayerItem(url: urlVideoPath)
    self.avPlayer = AVPlayer(playerItem: newPlayerItem)
    avPlayerController.player = self.avPlayer
    self.avPlayer?.addObserver(self, forKeyPath: "status", options: NSKeyValueObservingOptions(rawValue: 0), context: MPPlayableContentManagerContext.observationInfo())
    self.present(avPlayerController, animated: true) {
        self.avPlayer?.play()
    }
}
