Send Feedback

Override this member function to handle notification of a change of sample rate.

virtual HRESULT ChangeRate( ) PURE;

Parameters

None.

Return Values

Returns an HRESULT value that depends on the implementation. HRESULT can be one of the following standard constants, or other values not listed.

Value Description
E_FAIL Failure.
E_POINTER Null pointer argument.
E_INVALIDARG Invalid argument.
E_NOTIMPL Method is not supported.
S_OK or NOERROR Success.

Remarks

This member function is called when a change to the rate has been made by a call to the CSourceSeeking::SetRate function.

Override this and change the rate of data sent.

Typically, you do this by calling CBaseInputPin::BeginFlush and CBaseInputPin::EndFlush, and then send samples marked with new time stamps (for example, with an implementation NewSegment method).

Requirements

DirectShow applications and DirectShow filters have different include file and link library requirements.
