您好，

您可以轻松使用GPI +，可能的GDI或Direct3D和DirectDraw，但使用GDI +可以轻松实现这一目的.

在这里，您可以看到带有文本覆盖的示例.它在C#中，但是实现方式相似.

在C#中使用纯.NET DirectShow过滤器 [

Hello,

You can easy use GPI+, possible GDI or Direct3D and DirectDraw but GDI+ easy to make that.

Here you can see the sample with text overlay. it''s in C#, but implementation similar.

Pure .NET DirectShow Filters in C#[^]
