IAMClockSlave::SetErrorTolerance 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetErrorTolerance
method sets the audio renderer's rate-matching tolerance.
Syntax
HRESULT SetErrorTolerance(
[in] DWORD dwTolerance
);
Parameters
[in] dwTolerance
Specifies the maximum tolerance, in milliseconds. The value must be from 1 to 1000, inclusive.
Return value
Returns an HRESULT value. Possible values include the following.
Return code | Description |
---|---|
|
Failure. |
|
Success. |
|
The filter graph is not stopped. |
Remarks
Changing the tolerance has no effect unless the audio renderer is matching rates with a different clock. If the audio renderer is the reference clock, the audio is always synchronized to the clock (by definition).
This method fails if the filter graph is not stopped.
