[WiP] madVR support in MP1 (8 Viewers)

[Sebastiii]

btw the code for restore :

Log("MPMadPresenter::Destructor() - m_pMad release 1");
    if (m_pMad)
    {
      // Let's madVR restore original display mode (when adjust refresh it's handled by madVR)
      if (Com::SmartQIPtr<IMadVRCommand> pMadVrCmd = m_pMad)
      {
        pMadVrCmd->SendCommand("restoreDisplayModeNow");
        pMadVrCmd.Release();
        Log("MPMadPresenter::Destructor() - restoreDisplayModeNow");
      }
      m_pMad.FullRelease();
    }
    Log("MPMadPresenter::Destructor() - m_pMad release 2");

Thanks, tested with the videohelp.com linked version and MadVR is restoring refresh rate correctly there when Kodi is on either primary or secondary screen.

Nice so now why on MP it doesn't works
maybe and surely because of some kind of delay introduced by c# vs c++ or it's something else.

Kodi DS code :

CmadVRAllocatorPresenter::~CmadVRAllocatorPresenter()
{
  if (m_pSRCB) {
    // nasty, but we have to let it know about our death somehow
    ((CSubRenderCallback*)(ISubRenderCallback2*)m_pSRCB)->SetDXRAP(nullptr);
  }
 
  if (m_pORCB) {
    // nasty, but we have to let it know about our death somehow
    ((COsdRenderCallback*)(IOsdRenderCallback*)m_pORCB)->SetDXRAP(nullptr);
  }

  // Unregister madVR Exclusive Callback
  if (Com::SmartQIPtr<IMadVRExclusiveModeCallback> pEXL = m_pDXR)
    pEXL->Unregister(m_exclusiveCallback, this);

  // Let's madVR restore original display mode (when adjust refresh it's handled by madVR)
  if (Com::SmartQIPtr<IMadVRCommand> pMadVrCmd = m_pDXR)
    pMadVrCmd->SendCommand("restoreDisplayModeNow");

  g_renderManager.UnInit();
  g_advancedSettings.m_guiAlgorithmDirtyRegions = m_kodiGuiDirtyAlgo;
 
  // the order is important here
  CDSRendererCallback::Destroy();
  SAFE_DELETE(m_pMadvrShared);
  m_pSubPicQueue = nullptr;
  m_pAllocator = nullptr;
  m_pDXR = nullptr;
  m_pORCB = nullptr;
  m_pSRCB = nullptr;

  CLog::Log(LOGDEBUG, "%s Resources released", __FUNCTION__);
}

Maybe it's not C++ issue, i will need to try something with you

 

[Rick164]

Yeah think it releases / restored the window correctly, before it crashed when restoring refresh rate with secondary window so maybe it's the fix from V227-229 (not sure which) ?
On IRC so can ping if you have the time

What we could try is to log the specific steps and see if perhaps it's crashing before it can reach "restoreDisplayModeNow" , any idea if we need to store the current display refresh rate on renderer start for MadVR or is that handled internally?
We also have some MPC-HC examples here:

https://fossies.org/windows/misc/mpc-hc-1.7.10.zip/mpc-hc-1.7.10/include/mvrInterfaces.h
https://github.com/MediaBrowser/Emby.Theater.Windows/blob/master/Emby.Theater.DirectShow/MadvrInterface.c <-- Looks incomplete

Thanks
mvrinterfaces.h comes from madshi bin
The other one i have take some part but didn't work correctly under MP lol

Hey

i can reproduce the issue about not refresh rate on multi-screen and manage to fix it (not sure if it will solve the issue on crimson driver @joecrow)
I will link to a new installer in first post asap

V233 in first post

It may be academic, I'm almost decided on keeping the Nvidia GTX 1050 Ti, maybe @Kotik or @GeYe can give some feedback.
