ICaptureGraphBuilder2 Interface
The ICaptureGraphBuilder2 interface builds capture graphs and other custom filter graphs. The Capture Graph Builder object implements this interface.
- **Note **By default, the ICaptureGraphBuilder2 interface does not use the Video Mixing Renderer (VMR), Enhanced Video Renderer (EVR) or Video Port Manager filters.
In addition to the methods inherited from IUnknown, the ICaptureGraphBuilder2 interface exposes the following methods.
| Method | Description |
| AllocCapFile | Preallocates a capture file to a specified size. |
| ControlStream | Sets the start and stop times for one or more streams of captured data. |
| CopyCaptureFile | Copies the valid media data from a capture file. |
| FindInterface | Searches the graph for a specified interface, starting from a specified filter. |
| FindPin | Retrieves a particular pin on a filter, or determines whether a given pin matches the specified criteria. |
| GetFiltergraph | Retrieves the filter graph that the builder is using. |
| RenderStream | Connects an output pin on a source filter to a rendering filter, optionally through a compression filter. |
| SetFiltergraph | Specifies a filter graph for the capture graph builder to use. |
| SetOutputFileName | Creates the file writing section of the filter graph. |
