[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]

The Capture method captures the video frame that is currently being rendered by the Video Mixing Renderer (VMR).

Syntax

HRESULT Capture(
  [out] IPictureDisp **currentImage
);

Parameters

[out] currentImage

Receives an IPictureDisp interface pointer.

Return value

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

The returned IPictureDisp interface has an outstanding reference count. The caller must release the interface.

For information about the IPictureDisp interface, see the Microsoft Platform SDK documentation.

hr = m_pVideoControl->get_VideoRendererActive(&pVideo);
if (SUCCEEDED(hr))
{
    // Capture the image.
