c#使用Microsoft.DirectX.AudioVideoPlayback如何在完成一個視頻后播放下一個視頻

[英]c# using Microsoft.DirectX.AudioVideoPlayback how to play next video after one is finished

我可以將視頻放入Windows窗體中。

我的問題是,當它完成播放視頻后,如何開始播放另一個視頻,我該如何制作? 意思是按順序排列。 完成后,播放另一個視頻。

到目前為止,我已經能夠播放視頻,並且只是循環播放視頻。

有任何想法嗎?

到目前為止,這是我的代碼:

public partial class Form1 : Form
{
     Video video;



    public Form1()
    {
        InitializeComponent();          
        Initializevid1();

    }

    public void Initializevid1()
    {

           // store the original size of the panel
            int width = viewport.Width;
            int height = viewport.Height;

            // load the selected video file
            video = new Video("C:\\Users\\Dave\\Desktop\\WaterDay1.wmv");

            // set the panel as the video object’s owner
            video.Owner = viewport;

            // stop the video
            video.Play();
            video.Ending +=new EventHandler(BackLoop);

            // resize the video to the size original size of the panel
            viewport.Size = new Size(width, height);   

    }

    private void BackLoop(object sender, EventArgs e)
    {

        //video.CurrentPosition = 0;
    }

在AudioVideoPlayback中播放視頻序列時:

  1. 創建要顯示的視頻列表(使用文件路徑),最好在列表框中。

  2. 使用整數從listbox.items索引獲取文件路徑。

  3. 加載下一個視頻之前,請確保已處理視頻。

  4. 每次播放視頻時遞增的整數。

  5. 使用if語句查看它是否是序列的結尾。

  6. 根據個人喜好(不確定會帶來多大的改變),我會在播放前調整視頻大小

因此,根據您的代碼:(尚未測試,但從理論上講,我認為它應該可以工作)

    public partial class Form1 : Form
    {
        Video video;
        Int SeqNo = 0;

        public Form1()
        {
            InitializeComponent();          
            Initializevid1();

        }

        public void Initializevid1()
        {

               // store the original size of the panel
                int width = viewport.Width;
                int height = viewport.Height;

                // load the selected video file
                video = new Video(listbox1.Items[SeqNo].Text);

                // set the panel as the video object’s owner
                video.Owner = viewport;

                // resize the video to the size original size of the panel
                viewport.Size = new Size(width, height);   

                // stop the video
                video.Play();

                // start next video
                video.Ending +=new EventHandler(BackLoop);
        }

        private void BackLoop(object sender, EventArgs e)
        {
            // increment sequence number
            SeqNo += 1;            //or '++SeqNo;'

            //check video state
            if (!video.Disposed)
            {
                video.Dispose();
            }

            //check SeqNo against listbox1.Items.Count -1 (-1 due to SeqNo is a 0 based index)
            if (SeqNo <= listbox1.Items.Count -1)
            {


               // store the original size of the panel
                int width = viewport.Width;
                int height = viewport.Height;

                // load the selected video file
                video = new Video(listbox1.Items[SeqNo].Text);

                // set the panel as the video object’s owner
                video.Owner = viewport;

                // resize the video to the size original size of the panel
                viewport.Size = new Size(width, height);   

                // stop the video
                video.Play();


                // start next video
                video.Ending +=new EventHandler(BackLoop);
           }
        }

我用這篇文章來適應我的需求,這是我的解決方案:

Video _SegaVideo;
Video _IntroVideo;

public _FrmMain()
{
    InitializeComponent();

    _SegaVideo = new Video(@"video\SEGA.AVI");
    _SegaVideo.Owner = _VideoPanel;
    _SegaVideo.Play();
    _SegaVideo.Ending += new EventHandler(_SegaVideoEnding);

}

private void _SegaVideoEnding(object sender, EventArgs e)
{
    _IntroVideo = new Video(@"video\INTRO.AVI");
    _IntroVideo.Owner = _VideoPanel;
    _IntroVideo.Play();
}

您可以使用先前創建的相同視頻對象在BackLoop()函數中打開第二個視頻文件。

因此,代碼應如下所示:

private void BackLoop(object sender, EventArgs e)
{
    video.Open("C:\\Users\\Dave\\Desktop\\WaterDay2.wmv", true);
}
