Memory Leaks in Window Media Player + c#

[Pankaj Safaltek]

Hi

I am facing some memory leaks in windowmediaplayer after disposing it.
Following is the code

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

AxWMPLib.AxWindowsMediaPlayer m = new AxWMPLib.AxWindowsMediaPlayer();

private void start_Click(object sender, EventArgs e)
{
this.Controls.Add(m);
m.Location = new System.Drawing.Point(1, 1);
m.Height = 130;
m.Width = 150;

m.URL = @"C:\Users\Public\Videos\Sample Videos\Bear.wmv";
}

private void stop_Click(object sender, EventArgs e)
{
m.URL = null;
m.close();
m.Dispose();

}
}

On clicking stop, it is still keeping the following in the memory

System.Windows.Forms.AxHost.ConnectionPointCookie
AxWMPLib.AxWindowsMediaPlayerEventMulticaster


Please Help

Thanks

Pankaj Safaltek,

Try the following:

private void stop_Click(object sender, EventArgs e)
{
    m.URL = null;
    m.close();
    m.Dispose();
    Marshal.FinalReleaseComObject(m);
}

Regards,

Hi

I am getting the following crash
The object's type must be __ComObject or derived from __ComObject.
Parameter name: o


On the execution of following code.

System.Runtime.InteropServices.Marshal.FinalReleaseComObject(m);

Please help.

Try the following:

private void stop_Click(object sender, EventArgs e)
{
    bool test1 = false;
    bool test2 = false;

    test1 = System.Runtime.InteropServices.Marshal.IsComObject(m);
    m.URL = null;
    m.close();
    m.Dispose();
    test2 = System.Runtime.InteropServices.Marshal.IsComObject(m);
}

Are test1 and test2 both false after running?

[Pankaj Safaltek]

Yes, Both are false.

Try the following:

private void stop_Click(object sender, EventArgs e)
{
    m.URL = null;
    m.close();
    m.Dispose();
    m = null;
}

Does that stop the momory leak?

No

Do you need to create this every time you start and destruct it every time you stop a video?

Perhaps

using (m = new mediaplayer())
{
            Application.Run(new MediaForm(m));
}
