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.

C#

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();

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

Humm... the code is too simple to works properly. First, there is probably an header at the beginning of each file. Second, you must ensure that both files use a compatible format (and rate) or do appropriate convertion. Finally, you must probably update header information with things like new length. And you might also have to take into account somee alignment issues.

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

Part 1:

C#

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

Part 2:

under:

C#

public Form1()
        {
            InitializeComponent();
        }

enter code:

C#

[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

Part 3:

C#

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);

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