CBaseRenderer::CompleteStateChange (Windows Embedded CE 6.0)

1/6/2010

Ensures that a sample is waiting before allowing a pause.

Syntax

virtual HRESULT CompleteStateChange(
  FILTER_STATE OldState
);

Parameters

  • OldState
    State prior to the transition.

Return Value

Returns S_OK if the filter can be paused; otherwise, returns S_FALSE.

Remarks

This member function is called from the CBaseRenderer::Pause member function.

If the filter is being paused and there is no sample waiting, the transition is not completed and the function returns S_FALSE until the first sample arrives.

However, if the m_bAbort flag is set, all samples are rejected so there is no point waiting for one.

If a sample is available, this member function returns NOERROR.

Requirements

Windows Embedded CE Windows CE 2.12 and later
Note Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements
For more information, see Setting Up the Build Environment, Version 2.12 requires DXPAK 1.0 or later
