CTransformInputPin::CheckStreaming

  • Article

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.

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements. See Setting Up the Build Environment for more information.

OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
