This method determines which capabilities exist on a media stream by applying seeking capability flags and checking the returned value.
HRESULT CheckCapabilities( DWORD* pCapabilities );
[in, out] Pointer to an AM_SEEKING_SEEKING_CAPABILITIES enumeration type containing the seeking capabilities flags to apply. These flags can be any combination of the following:
Returns S_OK if all capabilities in pCapabilities are present, S_FALSE if some are present, or E_FAIL if none are present.
This method determines which seeking capabilities are present on a media stream. It applies the pCapabilities flags using a bitwise-AND operation, and returns a value to indicate whether they match the capabilities of the media stream. The value of pCapabilities is accumulated between successive calls to this method so that the value of pCapabilities can be checked when an S_FALSE value is returned to find the capability that does not match.
