CBaseRenderer::GetState

  • 项目

Determines the state of the renderer.

HRESULT GetState(
  DWORD dwMilliSecsTimeout,
  FILTER_STATE* State
);

Parameters

  • dwMilliSecsTimeout
    Duration of the time-out, in milliseconds.
  • State
    Returned state of the renderer.

Return Values

Returns an HRESULT value. Returns VFW_S_STATE_INTERMEDIATE if paused and waiting for a sample; otherwise, returns NOERROR.

Remarks

This member function overrides the CBaseFilter::GetState member function. It returns the value of m_State. Because the renderer does not complete the full transition to the paused state until it has a sample to render, if the state is requested while it is waiting for a sample, it will return VFW_S_STATE_INTERMEDIATE along with the state.

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.
