When running an application in Qt5 made ​​using the QWebView, I accessed a page with a video player in HTML5, but the video does not play and qt/directshow shows the following error:

DirectShowPlayerService::doRender: Unresolved error code 80040218 DirectShowPlayerService::doRender: Unresolved error code 80040218

Details:

  • Qt5.1.1 MingW4.8 32bit
  • Windows 7 64bit

I suspect that is why my Windows is 64bit, but the *QT/MingW** runs on 32bit and maybe miss some DLL/LIB.

How can I resolve this?

Thanks.

The error code is rather generic: 0x80040218 VFW_E_CANNOT_RENDER "No combination of filters could be found to render the stream." and the typical cause is that the application cannot decode media feed because it lacks decoding components, such as codec for this video feed is not installed/available.
