IAMPushSource::SetStreamOffset method (strmif.h)
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetStreamOffset method sets the offset for time stamps generated by this filter.
Syntax
HRESULT SetStreamOffset(
[in] REFERENCE_TIME rtOffset
);
Parameters
[in] rtOffset
New stream offset for the filter.
Return value
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.
