... instead of index of DXGI adapter. The order of IDXGIAdapter1 enumerated via IDXGIFactory1::EnumAdapters1 can be varying even there's no rebooting in case that GPU preference order is updated by user (for example, it can be done by using NVIDIA Control Panel in case of multi-GPU laptop system) and eGPU is another possible case. So, for an element which requires fixed target GPU requirement, index based device enumeration is unreliable. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1098>
