c#使用Microsoft.DirectX.AudioVideoPlayback如何播放下一个视频完成后
问题描述:
我可以把视频放在我的窗体中。c#使用Microsoft.DirectX.AudioVideoPlayback如何播放下一个视频完成后
我的问题是我如何使它完成播放视频时,它开始播放另一个视频?意思就像一个序列。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。
有什么想法?
这是我到目前为止的代码:
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;
}
答
您可以使用之前创建要打开BackLoop()
函数的第二个视频文件的同一视频对象。
所以,代码看起来应该像什么这样的:
private void BackLoop(object sender, EventArgs e)
{
video.Open("C:\\Users\\Dave\\Desktop\\WaterDay2.wmv", true);
}

当AudioVideoPlayback播放视频序列:
创建的视频列表进行显示(使用文件路径),最好在一个列表框中。
使用整数从listbox.items索引获取文件路径。
确保在加载下一个视频之前放置视频。
每次播放视频时递增整数。
使用if语句来查看它是否是序列的结尾。
由于个人喜好(不知道它有多大的重要性),我会调整视频播放
所以从您的代码之前:(没有测试过这一点,但在理论上,我认为这应工作)
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);
}
}

我用这篇文章,以使其适应我的需要,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();
}
