IGraphConfig::SetFilterFlags 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetFilterFlags method sets a filter's configuration information.
Syntax
HRESULT SetFilterFlags(
[in] IBaseFilter *pFilter,
[in] DWORD dwFlags
);
Parameters
[in] pFilter
Pointer to the IBaseFilter interface of a filter in the filter graph.
[in] dwFlags
Value specifying the new configuration flags. Must be one of the following values.
| Value | Description |
|---|---|
| Zero | No flags set. |
| AM_FILTER_FLAGS_REMOVABLE | The filter is removable during a dynamic reconnection. For more information, see Remarks. |
Return value
Returns one of the following HRESULT values.
| Return code | Description |
|---|---|
|
NULL pointer argument. |
|
Invalid argument. |
|
Success. |
|
The filter is not in the graph. |
Remarks
The AM_FILTER_FLAGS_REMOVABLE flag changes the behavior of the IGraphConfig::Reconnect method. The Reconnect method performs a dynamic reconnection between two pins. If the caller specifies one pin, but leaves the other pin unspecified, Reconnect searches upstream or downstream from the specified pin to find a suitable match. By default, however, the search fails if it reaches a filter that was added to the graph by means of the IFilterGraph::AddFilter method. To override this behavior, call SetFilterFlags and set the AM_FILTER_FLAGS_REMOVABLE flag on the filter.
