IMediaFilter::SetSyncSource (Windows Embedded CE 6.0)
1/6/2010
This method identifies the reference clock to which the filter should synchronize activity.
Syntax
HRESULT SetSyncSource(
IReferenceClock* pClock
);
Parameters
- pClock
[in] Pointer to the IReferenceClock interface.
Return Value
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 method is of most importance to rendering filters and might not apply to other filters. The pClock parameter can be NULL, meaning that the filter should run as fast as possible at its current quality settings without any attempt to synchronize. For example, a filter graph that is doing compression probably runs in this mode. Each filter takes as long as it needs.
Requirements
| Windows Embedded CE | Windows CE 2.12 and later |
| Note | Microsoft DirectShow applications and DirectShow filters have different include file and Library requirements For more information, see Setting Up the Build Environment, Version 2.12 requires DXPAK 1.0 or later |
