I am doing a monitoring system which has opened four windows(Activex) decoding with Intel Media SDK at the same time. Every window is using directshow framework. These windows will initiate decoder(Intel MSDK) every 30 seconds to connect different video sources. But some windows will lay off after half hour. Through WinDebug, I find that the app constantly reported "Access Violation" in MFXVideoVPP_GetVPPStat function and come into endless loop. Please, see the attachment.
Windows Embedded Standard SP1 ,32bit Operating System
Intel Media SDK V188.8.131.5271
But, another computer has entirely same devices and drivers. Just, it runs Windows7 Enterprise. My app has been running for 48 hours. Thanks for you help.
