Defines the preferred video renderer type.
public enum VideoRendererType Public Enum VideoRendererType
public enum class VideoRendererType Members
| Value | Member | Description |
|---|---|---|
| 0 | Legacy | Specifies the preferred renderer to be Microsoft Legacy Video Renderer. |
| 1 | VMR7 | Specifies the preferred renderer to be Microsoft VMR7 Video Renderer. |
| 2 | VMR9 | Specifies the preferred renderer to be Microsoft VMR9 Video Renderer. VMR9 is the default value. |
| 3 | NULL | Specifies the preferred renderer to be Null Renderer. In this case, the video samples will pass through the graph at the specified playback rate, but will not be displayed, so you will need to implement your own drawing. This is useful when you want to do your own drawing using GDI or OpenGL. You would typically retrieve the samples using the LEAD Video Callback Filter. |
| 4 | EVR | Specifies the preferred renderer to be Microsoft Enhanced Video Renderer (EVR). |
The default value is VideoRendererType.VMR9. LEADTOOLS will automatically try the assigned video renderer preference. If that fails, then LEADTOOLS will step down to an earlier version of the renderer, until all renderers are exhausted. If you are on a system that supports VMR7 or VMR9, then the Legacy renderer is not automatically attempted unless the user explicitly sets Legacy as a preference. This prevents screen flashing on these systems.
