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 HRESULTvalue that depends on the implementation of the interface. The default DirectShow implementation returns S_OK if pFormatis the current time format; otherwise returns S_FALSE.
Remarks
This can be used in place of IMediaSeeking::GetTimeFormatto compare time formats, since it is faster and does not require copying the GUID.
