CBasePin::Notify

Notifies the recipient that a quality change is requested.

HRESULT Notify(
  IBaseFilter* pSelf,
  Quality q
);

Parameters

  • pSelf
    Pointer to the filter that is sending the quality notification.
  • q
    Quality notification structure.

Return Values

The default base class implementation returns E_FAIL.

Remarks

This member function must be overridden to accept notifications. It is typically overridden to implement this method on the output pin because quality-control messages are passed upstream. The CTransformOutputPin::Notify member function is one example of how this member function is overridden to pass quality-control messages to the next filter upstream.

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.
