HRESULT GetCapabilities( DWORD* pCapabilities );
Parameters
- pCapabilities
- Seeking capability flags, which can be any combination of the
following:
- AM_SEEKING_CanGetCurrentPos
- AM_SEEKING_CanGetDuration
- AM_SEEKING_CanGetStopPos
- AM_SEEKING_CanPlayBackwards
- AM_SEEKING_CanSeekAbsolute
- AM_SEEKING_CanSeekBackwards
- AM_SEEKING_CanSeekForwards
Return Values
Returns the HRESULTvalue returned from calling IMediaSeeking::GetCapabilitieson the connected pin.
Remarks
This member function implements IMediaSeeking::GetCapabilitiesby calling the IMediaSeeking::GetCapabilitiesmethod on the upstream output pin connected to the peer input pin. The pin that performs the seek operation will return the capabilities present in the pCapabilitiesparameter. These returned capabilities will then, in turn, propagate to calls made from CPosPassThru::GetCapabilitiesmember functions in intervening filters.
