[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SyncUsingStreamOffset method enables or disables synchronization using time-stamp offsets.

Syntax

HRESULT SyncUsingStreamOffset(
  [in] BOOL bUseStreamOffset
);

Parameters

[in] bUseStreamOffset

Boolean value indicating whether to use a time-stamp offset. If TRUE, live sources will use a time-stamp offset to synchronize streams.

Return value

Returns S_OK if successful, or an error code otherwise.

Remarks

By default, the filter graph does not attempt to synchronize live streams by means of time-stamp offsets. Call this method with a value of TRUE if you want the filter graph to determine the maximum latency in the graph and adjust time stamps accordingly. For more information, see IAMPushSource::SetStreamOffset.
