IAMGraphStreams Interface
The IAMGraphStreams interface controls a filter graph that renders a live source. A live source is one that streams data in real time, such as a capture device or a network broadcast. The Filter Graph Manager implements this interface.
Applications can use this interface to specify how the graph handles latency and synchronization when it renders a live source. For more information, see Live Sources.
In addition to the methods inherited from IUnknown, the IAMGraphStreams interface exposes the following methods.
| Method | Description |
| FindUpstreamInterface | Searches the filter graph for a specified interface, upstream from a specified pin. |
| SyncUsingStreamOffset | Enables or disables synchronization using time-stamp offsets. |
| SetMaxGraphLatency | Sets the maximum latency for the graph. |
