IVPBaseConfig::SetInvertPolarity method (vpconfig.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 SetInvertPolarity method reverses the current polarity the device uses.
Syntax
HRESULT SetInvertPolarity();
Return value
Returns an HRESULT value.
Remarks
Reversing polarity means asking the decoder or capture device to treat even fields as odd fields and vice versa.
Include Dvp.h and Vptype.h before Vpconfig.h.
