IVMRFilterConfig9::SetRenderingPrefs

The SetRenderingPrefs method sets various application preferences related to video rendering.

Syntax

  HRESULT SetRenderingPrefs(
  DWORD  dwRenderFlags
);

Parameters

dwRenderFlags

[in]   Double word containing a bitwise OR of VMR9RenderPrefs values specifying the rendering preferences.

Return Values

The method returns an HRESULT. Possible values include those in the following table.

Value Description
S_OK The method succeeded.
VFW_E_WRONG_STATE No allocator-presenter is present.
E_INVALIDARG dwRenderFlags is invalid.

Remarks

This method calls through to the allocator-presenter's IVMRImagePresenterConfig9::SetRenderingPrefs method. (The default allocator-presenter exposes IVMRImagePresenterConfig9. Custom allocator-presenters can also expose this interface if desired.) If the VMR-9 has not yet created the default allocator-presenter, or if the application  provided a custom allocator-presenter which does not support IVMRImagePresenterConfig9, this method returns VFW_E_WRONG_STATE. To create the default allocator-presenter, call IVMRFilterConfig9::SetRenderingMode with the value VMR9Mode_Windowed or VMR9Mode_Windowed.

Requirements

Header: Include D3d9.h, Vmr9.h.

Library: Use Strmiids.lib.
