IMediaSeeking::IsUsingTimeFormat

  • 项目

This method determines if the time format being used in the call is the same as the one currently in use by the interface.

HRESULT IsUsingTimeFormat(
  const GUID* pFormat
);

Parameters

  • pFormat
    [in] Time format to check.

Return Values

Returns an HRESULT value that depends on the implementation of the interface. The default DirectShow implementation returns S_OK if pFormat is the current time format; otherwise returns S_FALSE.

Remarks

This can be used in place of IMediaSeeking::GetTimeFormat to compare time formats, because it is faster and does not require copying the GUID.

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.
