IMediaSeeking::IsUsingTimeFormat

The IsUsingTimeFormat method determines whether seek operations are currently using a specified time format.

Syntax

  HRESULT IsUsingTimeFormat(
  const GUID *pFormat
);

Parameters

pFormat

[in] Pointer to a GUID that specifies the time format. See Time Format GUIDs.

Return Values

Returns an HRESULT value. Possible values include the following.

Return code Description
S_FALSE The specified format is not the current format.
S_OK The specified format is the current format.
E_NOTIMPL Not implemented.
E_POINTER NULL pointer argument.

Remarks

This method is slightly more efficient than the IMediaSeeking::GetTimeFormat method, because it does not require copying the GUID.

Requirements

Header: Declared in Strmif.h; include Dshow.h.

Library: Use Strmiids.lib.
