IMediaSeeking::GetAvailable method (strmif.h)

The GetAvailable method retrieves the range of times in which seeking is efficient.

Syntax

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

Parameters

pEarliest

Pointer to a variable that receives the earliest time for efficient seeking.

pLatest

Pointer to a variable that receives the latest time for efficient seeking.

Return value

Returns an HRESULT value. Possible values include the following.

Return code Description
S_OK
Success.
E_NOTIMPL
Method is not supported.
E_POINTER
NULL pointer argument.

Remarks

This method is intended primarily for seeking in media streams that might have excessive latency, such as streams being sent over a network. 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 the application waits for the data to arrive.

All time values are expressed in the current time format. The default time format is REFERENCE_TIME units (100 nanoseconds). To change time formats, use the IMediaSeeking::SetTimeFormat method.
