Hi,
I am using filestream to join two are three videos. I stored the video files path in DataTable Video. The Video is joining. But the Problem is first video running normally, other videos are moving very fast. Like we given in fast forward.

FileStream fsSource = new FileStream("C:\\vide.mpg", FileMode.Append);
                    for (int i = 0; i < video.Rows.Count; i++)
                    {
                        FileInfo fi = new FileInfo(video.Rows[i][0].ToString());
                        Byte[] bytePart = System.IO.File.ReadAllBytes(fi.FullName);
                        fsSource.Write(bytePart, 0, bytePart.Length);                      
                    }
           fsSource.Close();

任何人都知道解决方案，请帮助我.谢谢.

Any one know the solution please help me. Thank you.

推荐答案

如果要同时播放2个视频，则需要输入3个代码部分:

第1部分:

If you want to play 2 videos at the same time you need to enter 3 parts of code:

Part 1:

using System.Runtime.InteropServices; //with this code you are able to import dll files

第2部分:

下:

Part 2:

under:

public Form1()
        {
            InitializeComponent();
        }

输入代码:

enter code:

[DllImport("winmm.dll")]
        private static extern long mciSendString(
            string command,
            StringBuilder returnValue,
            int returnLength,
            IntPtr winHandle);//imports a dll file and creates a new command

第3部分:

Part 3:

string filename1 = "";//position of first file
string filename2 = "";//position of second file
mciSendString("close mf1", null, 0, IntPtr.Zero);
mciSendString("close mf2", null, 0, IntPtr.Zero);
mciSendString("open \"" + filename1 + "\" type mpegvideo alias mf1 style child parent " + pictureBox1.Handle.ToString(), null, 0, IntPtr.Zero);
mciSendString("open \"" + filename2 + "\" type mpegvideo alias mf2 style child parent " + pictureBox2.Handle.ToString(), null, 0, IntPtr.Zero);
mciSendString("put mf1 window at 0 0 " + pictureBox1.Width.ToString() + " " + pictureBox2.Height.ToString(), null, 0, IntPtr.Zero);
mciSendString("put mf2 window at 0 0 " + pictureBox2.Width.ToString() + " " + pictureBox2.Height.ToString(), null, 0, IntPtr.Zero);
mciSendString("play mf1", null, 0, IntPtr.Zero);
mciSendString("play mf2", null, 0, IntPtr.Zero);

这对我有用；如果您想了解更多有关此代码的信息，请搜索MCI(媒体控制界面)

this worked for me;if you want to know more about this code search for MCI(Media Control Interface)
