IAMPushSource::SetStreamOffset
| Microsoft DirectShow 9.0 |
IAMPushSource::SetStreamOffset
The SetStreamOffset method sets the offset for time stamps generated by this filter.
Syntax
HRESULT SetStreamOffset( REFERENCE_TIME rtOffset );
Parameters
rtOffset
[in] New stream offset for the filter.
Return Values
Returns S_FALSE if the specified offset is larger than the filter's maximum preferred offset. Otherwise, returns S_OK if successful or an HRESULT value indicating the cause of the error.
Remarks
The filter graph calls this method to adjust a filter's stream offset, in order to synchronize streams with different latency values.
If the return value is S_FALSE, the filter might not support a buffer large enough for the requested offset. Unless there is another buffer downstream, data might be lost. To retrieve the filter's maximum preferred offset, call the IAMPushSource::GetMaxStreamOffset method.
Requirements
Header: Declared in Strmif.h; include Dshow.h.
Library: Use Strmiids.lib.
