Verifies conditions for continuing with a streaming operation.
HRESULT CheckStreaming( );
Parameters
None.
Return Values
Returns one of the following HRESULT values, depending on the state.
| Value | Description |
|---|---|
| S_FALSE | Currently in flushing state. |
| S_OK | Receive or EndOfStream operations can safely proceed. |
| VFW_E_NOT_CONNECTED | The output pin either does not exist or is not connected. |
| VFW_E_RUNTIME_ERROR | A run-time error occurred when processing a previous sample. |
| VFW_E_WRONG_STATE | The filter is in the State_Stopped state. |
Remarks
This member function overrides the CBaseInputPin::CheckStreaming member function and calls that base class implementation for most of the condition checks.
It determines if the pin is connected, if it is in a paused or running state, and if it is not currently flushing data or processing a run-time error.
