Is there any good solution so that i can avoid the flicker of video and the image. Further, when i move the panel i am unable to move the transaparent form. Is there any way for this too?

推荐答案

您可以尝试以表单的形式打开双缓冲.

You could try turning double-buffering on in the form.

Hii ！！！

尝试这种方式(在调用InitializeComponent之后在构造函数中执行此操作)是怎么可能的:

Try it this way (do this in the constructor AFTER the call to InitializeComponent):

this.SetStyle(ControlStyles.AllPaintingInWmPaint | 
              ControlStyles.UserPaint | 
              ControlStyles.DoubleBuffer, true);

顺便说一句，您本可以为自己找到答案.

BTW, you could have ggogled to find this out for yourself.
