CBasePin::QueryAccept

  • 项目

Determines whether the pin accepts the format type.

HRESULT QueryAccept(
  const AM_MEDIA_TYPE* pmt
);

Parameters

  • pmt
    Pointer to a proposed media type.

Return Values

Returns S_TRUE if the format is accepted; otherwise, returns S_FALSE.

Remarks

This member function implements the IPin::QueryAccept method. It simply calls the pure virtual CBasePin::CheckMediaType member function, which the derived class must implement, and maps any returned codes from CheckMediaType other than S_OK to S_FALSE.

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.
