D3D11 objects leak in the the MediaSDK samples

Hello,

 

I am testing the decode_sample and I noticed that the sample leaks D3D11 object. if enabling debug on D3D11 Device by using the D3D11_CREATE_DEVICE_DEBUG flag, on application exit the refCount on few objects is not 0:

please note that before calling "ReportLiveDeviceObjects" I've set all CComPtr/CComQIPtr class memebers to nullptr.

I found the leak in the sample_common project used in decode_sample and other projects as well.

 

in D3D11_device.cpp, RenderFrame method, there are 6 CComPtr class membersthat are passed to D3D11 functions with the row pointer, so the old object in the CComPtr is not cleared, the objects are:

 

m_pDXGIBackBuffer

m_pOutputView

m_pInputViewLeft

m_pTempTexture

m_pInputViewLeft

m_pInputViewRight

so the fix is to set those to nullptr before changing the row pointer.

I also suggest to add this in the distructor of the class:

m_pD3D11Ctx->ClearState();

m_pD3D11Ctx->Flush();
