Value Description
S_OK The method succeeded.
E_INVALIDARG An invalid rendering mode was specified.
VFW_E_WRONG_STATE The mode cannot be changed for some reason. See Remarks.


The VMR is in VMRMode_Windowed by default. Use this method only if you are putting the VMR into VMRMode_Windowless or VMRMode_Renderless mode. You cannot change the mode after any pin has been connected and you cannot change the mode from windowless or renderless back to windowed, even before any pins are connected. Therefore, specifying VMRMode_Windowed for Mode has no effect under any circumstances.


Include D3d9.h, Vmr9.h.
