从Unity的VideoPlayer中的StreamingAssets播放视频时发送Choppy Audio

Question

我一直在尝试加载我从AVPro Movie Capture (Free Version)录制的视频。视频文件以GB为单位，因此我使用ffmpeg命令-y -i RawVideo.avi -qscale 7 FinalVideo.avi对其进行了转换，并将其保存到StreamingAssets。我得到了理想的结果。现在我想在视频播放器中播放转换后的视频文件进行预览。但问题是，当从URL播放视频时，音频非常不稳定。我在Windows播放器和VLC中播放它很好。问题仅出现在Unity的VideoPlayer。

中

PreviewVideo类：

public class PreviewVideo : MonoBehaviour
{

    public GameObject VideoSelection;
    public GameObject RecordingCanvas;
    public GameObject FacebookCanvas;
    public GameObject Home;
    public Sprite pauseImage;
    public Sprite playImage;
    public VideoPlayer videoPlayer;
    public GameObject EmailCanvas;

    // Use this for initialization
    void Start ()
    {

    }

    public void Referesh()
    {
        videoPlayer.gameObject.GetComponent<SpriteRenderer> ().sprite = Resources.Load<Sprite> ("Thumbnails/" + StaticVariables.VideoToPlay);

        videoPlayer.url = Application.streamingAssetsPath + "/FinalVideo.avi";
    }

    public void PlayVideo()
    {
        if (!videoPlayer.isPlaying) {
            videoPlayer.Play ();
        }
    }

    public void Back ()
    {
        this.gameObject.SetActive (false);
        VideoSelection.SetActive (true);
    }

    public void HomeBtn ()
    {
        SceneManager.LoadScene (0);
    }

    public void SendEmailDialogue()
    {
        EmailCanvas.SetActive (true);
        this.gameObject.SetActive (false);
    }

    public void FacebookShare()
    {
        FacebookCanvas.SetActive (true);
    }
}

从RecordingCanvas类调用

Refresh()：

public class RecordingCanvas : MonoBehaviour {

    public GameObject VideoSelection;
    public GameObject PreviewVideo;
    public GameObject Home;
    public GameObject canvas;
    public RawImage rawImage;
    public GameObject videoThumbnail;
    float _seconds;
    bool canStart = false;
    public SpriteRenderer NumSprite;
    public VideoPlayer videoPlayer;
    WebCamTexture webcamTexture;
    Process process;
    void Start ()
    {
        Refresh ();
    }

    public void Refresh()
    {
        _seconds = 0;
        NumSprite.gameObject.SetActive(true);
        webcamTexture = new WebCamTexture (1280, 720);
        webcamTexture.Stop ();
        rawImage.texture = webcamTexture;
        rawImage.material.mainTexture = webcamTexture;
        webcamTexture.Play ();
        videoPlayer.loopPointReached += VideoEndReached;

        videoPlayer.gameObject.GetComponent<SpriteRenderer> ().sprite = Resources.Load<Sprite> ("Thumbnails/" + StaticVariables.VideoToPlay);
        videoThumbnail.GetComponent<SpriteRenderer> ().sprite = Resources.Load<Sprite> ("Thumbnails/" + StaticVariables.VideoToPlay);
        videoPlayer.clip = Resources.Load<VideoClip> ("Videos/" + StaticVariables.VideoToPlay);
    }

    void Update()
    {
        _seconds += Time.deltaTime;
        print ((int)_seconds);
        if (_seconds < 1) {
            NumSprite.sprite = Resources.Load<Sprite> ("Numbers/3");
        }
        else if(_seconds <2)
            NumSprite.sprite = Resources.Load<Sprite>("Numbers/2");
        else if(_seconds <3)
            NumSprite.sprite = Resources.Load<Sprite>("Numbers/1");


        if (_seconds >= 3 && _seconds <=4 ) {
            canStart = true;
        }

        if (canStart) {
            NumSprite.gameObject.SetActive(false);
            canStart = false;
            FindObjectOfType<CaptureGUI> ().StartCapture();
            videoPlayer.Play ();
            videoThumbnail.SetActive (false);
        }

    }

    IEnumerator StartConversion()
    {
        yield return new WaitForSeconds (1.5f);
        process = new Process();

        if (File.Exists (Application.streamingAssetsPath + "/FinalVideo.avi"))
            File.Delete(Application.streamingAssetsPath + "/FinalVideo.avi");

        process.StartInfo.WorkingDirectory = Application.streamingAssetsPath;
        process.StartInfo.FileName = Application.streamingAssetsPath + "/ffmpeg.exe";
        process.StartInfo.Arguments = " -y -i " + StaticVariables.RawVideo + ".avi " + "-qscale 7 " + StaticVariables.FinalVideo + ".avi";
        process.StartInfo.CreateNoWindow = false;
        process.EnableRaisingEvents = true;
        process.Exited += new EventHandler(Process_Exited);
        process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
        process.Start();
        process.WaitForExit ();
        canvas.SetActive (false);
        PreviewVideo.SetActive (true);
        FindObjectOfType<PreviewVideo> ().Referesh ();
        File.Copy (Application.streamingAssetsPath + "/FinalVideo.avi", @"C:\xampp\htdocs\facebook\images\FinalVideo.avi", true);
        this.gameObject.SetActive (false);
    }

    void Process_Exited(object sender, EventArgs e)
    {
        process.Dispose ();
    }

    void VideoEndReached(UnityEngine.Video.VideoPlayer vp)
    {
        videoPlayer.Stop ();
        FindObjectOfType<CaptureGUI> ().StopCapture();
        webcamTexture.Stop ();
        canvas.SetActive (true);
        StartCoroutine(StartConversion ());
    }

}

我使用的是Unity版2017.1.1p4个人版。 Windows 10与高端PC。我正在为独立PC制作这个应用程序。

我被困在这里。无法继续前进。请帮我解决这个问题。
