The GetMaxStreamOffset method retrieves the maximum stream offset the filter can support.
HRESULT GetMaxStreamOffset( REFERENCE_TIME *prtMaxOffset );
[out] Pointer to a variable that receives a reference time indicating the maximum offset the filter can support.
Returns an HRESULT value that depends on the implementation of the interface. The DirectShow implementation returns E_POINTER or S_OK.
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.
