IMediaSeeking::GetAvailable

  • Article

Returns the range of times in which seeking is efficient.

HRESULT GetAvailable(
LONGLONG *pEarliest,
LONGLONG *pLatest);

Parameters

  • pEarliest
    [out] Earliest time that can be efficiently seeked to.
  • pLatest
    [out] Latest time that can be efficiently seeked to.

Return Values

Returns an HRESULT value that depends on the implementation of the interface. The default DirectShow implementation returns S_OK for success and E_NOTIMPL if the method is not implemented.

Remarks

This method is intended primarily for seeking in media streams that might have excessive latency, such as when playing back media "live" from an Internet server. The returned values indicate cached data that has already arrived, which can be easily seeked. It is assumed that seeking to values beyond these returned parameters will cause a delay while waiting for the data to arrive.
