[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The GetMaxStreamOffset method retrieves the maximum stream offset the filter can support.

Syntax

HRESULT GetMaxStreamOffset(
  [out] REFERENCE_TIME *prtMaxOffset
);

Parameters

[out] prtMaxOffset

Pointer to a variable that receives a reference time indicating the maximum offset the filter can support.

Return value

Returns an HRESULT value that depends on the implementation of the interface. The DirectShow implementation returns E_POINTER or S_OK.

Remarks

If the stream offset is set to a value larger than the maximum supported offset, the filter is not guaranteed to have a buffer large enough to hold data for the entire amount of the offset. Unless there is another buffer downstream, data might be lost.
