IMediaSeeking::GetAvailable

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

Syntax

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

Parameters

pEarliest

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

pLatest

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

Return Value

Returns an HRESULT value. Possible values include the following.

Value 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.
