The string returned from IMFAttributes::GetString with MF_DEVSOURCE_ATTRIBUTE_SOURCE_TYPE_VIDCAP_SYMBOLIC_LINK or MF_DEVSOURCE_ATTRIBUTE_SOURCE_TYPE_AUDCAP_SYMBOLIC_LINK this is device interface string which we can use as input to CM_Get_Device_Interface_PropertyW. The only piece of data I have is it's "symbolic link" (in my case, this string: \\?\usb#vid_04b4&pid_8888&mi_00#9&4fe28be&0&0000#)Īll 3 are USB devices, all 3 are listed when calling MFEnumDeviceSources but their "symbolic link" doesn't resolve into a hardware device. This article helps you get started with a new Webex for Government organization. The tools integrate with work flows on personal computers, mobile devices, and shared video devices (like conference room systems). Is there a way to do so? I can't find how to get "device" info from that activation object. The Webex for Government collaboration tools enable users to message, call, share, and meet with each other. What I'm looking for is to get that information from a given IMFActivate object. That info is available through Windows' Unified device property model APIs. semi-useful, like "Location 0 (Internal High Definition Audio Bus)" or "PCI bus 9, device 0, function 0". human-readable, like "on NVIDIA GeForce GTX 1080".When going to Windows' "Device manager" and clicking on (almost) any device in the list one piece of information in the "General" tab is called "Location".
