[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 InformVPInputFormats method informs the device what video formats the video port supports.

Syntax

HRESULT InformVPInputFormats(
  [in] DWORD           dwNumFormats,
  [in] LPDDPIXELFORMAT pDDPixelFormats
);

Parameters

[in] dwNumFormats

Number of video formats contained in the pDDPixelFormats parameter.

[in] pDDPixelFormats

Pointer to an array of pixel format structures (DDPIXELFORMAT) to send to the device.

Return value

Returns S_FALSE if failure, or S_OK otherwise.

Remarks

The supplied array of supported video port formats might determine what formats the device, in turn, proposes.

The DDPIXELFORMAT structure is documented in the Windows DDK.

Include Dvp.h and Vptype.h before Vpconfig.h.
