c#using Microsoft.DirectX.AudioVideoPlayback如何在完成后播放下一个视频

我可以将视频放入我的窗体中。

我的问题是如何在播放视频时制作它,它又开始播放另一个视频?意思是像一个序列。完成后,播放另一个视频。

到目前为止,我已经设法播放视频,它只是循环播放视频。

任何想法?

到目前为止,这是我的代码:

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;
    }

3 个答案:

答案 0 :(得分:1)

在AudioVideoPlayback中播放视频序列时:

  1. 创建要显示的视频列表(使用文件路径),最好是在列表框中。

  2. 使用整数从listbox.items索引获取文件路径。

  3. 确保在加载下一个视频之前处置视频。

  4. 每次播放视频时增加整数。

  5. 使用if语句查看它是否是序列的结尾。

  6. 作为个人喜好(不确定它有多大差异)我会在播放之前调整视频大小

  7. 所以从您的代码:(没有测试过这个,但理论上,我认为它应该有效)

        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);
               }
            }
    

答案 1 :(得分:0)

您可以使用之前创建的同一视频对象在BackLoop()功能中打开第二个视频文件。

所以,代码看起来应该是这样的:

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

我使用这篇文章来根据我的需要调整它,这是我的解决方案:

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();
}
