c# using Microsoft.DirectX.AudioVideoPlayback how to play next video after one is finished
i am able to put a video in my windows form.
my question is how do i make it w开发者_开发知识库hen it finishes playing the video,it starts to play another video? meaning like in a sequence. after it finishes, play another video.
so far i have manage to play a video and it just loops the video.
any ideas?
this is my code so far:
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;
}
When playing video sequences in AudioVideoPlayback:
Create a list of videos to be displayed (using file paths), preferably in a listbox.
Use an integer to get file path from the listbox.items index.
Ensure video is disposed before loading next video.
Increment integer every time a video is played.
Use an if statement to see if it is the end of the sequence.
As a personal preference (not sure how much difference it makes) I would resize video before playing
So from your code: (haven't tested this, but in theory, I think it should work)
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);
}
}
You can use the same video object created earlier to open the second video file in the BackLoop()
function.
So, the code should look like something this:
private void BackLoop(object sender, EventArgs e)
{
video.Open("C:\\Users\\Dave\\Desktop\\WaterDay2.wmv", true);
}
I used this post to adapt it to my needs and this was my solution:
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();
}
