Needed for Gungrave G.O.R.E. (besides some bits in raw AAC handling).
The game is fine with GetInputStatus always returning MFT_INPUT_STATUS_ACCEPT_DATA for both h264 and aac but I think it is better to be correct here.
-- v2: winegstreamer: Set MF_SA_D3D11_AWARE attribute for h264 transform. winegstreamer: Implement _GetInputStatus() for aac decoder transform.
