IVMRFilterConfig::SetRenderingPrefs

 
Microsoft DirectShow 9.0

IVMRFilterConfig::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 VMRRenderPrefs values specifying the rendering preferences.

Return Values

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

Error Code Description
VFW_E_WRONG_STATE No allocator-presenter is present.
E_INVALIDARG dwRenderFlags is invalid.

Remarks

This method calls through to the allocator-presenter's IVMRImagePresenterConfig::SetRenderingPrefs method. (The default allocator-presenter exposes IVMRImagePresenterConfig. Custom allocator-presenters can also expose this interface if desired.) If the VMR-7 has not yet created the default allocator-presenter, or if the application  provided a custom allocator-presenter which does not support IVMRImagePresenterConfig, this method returns VFW_E_WRONG_STATE. To create the default allocator-presenter, call IVMRFilterConfig::SetRenderingMode with the value VMRMode_Windowed or VMRMode_Windowed.

Requirements

Header: Declared in Strmif.h; include Dshow.h.

Library: Use Strmiids.lib.
