libva does not select the device by itself, it get the device from application or other components.
lets use drm as the example:
application call fd =open("/dev/dri/renderXXX",...) , then call vaGetDisplayDRM(fd), then call vaInitialize()
so, all is controlled in upper layer.
maybe you want a priority list in libva-utils?

@XinfengZhang It seems to be causing the driver to crash https://github.com/intel/libva-utils/blob/2.19.0/common/va_display_drm.c#L49-L51

DRM_IOCTL_VERSION, unsupported drm device by media driver: amdg
Instead of amdg it should be amdgpu, instead of nvid it should be nvidia.
