OBS virtual camera connection problems

[PimBeentjes]

Hi everyone, I am using obs to create a virtual camera. This works because I can select it for example in teams and it gives me the video that I want. My problem when using OBS in combination with Plus is that plus just refuses to recognize the obs virtual camera. Looking at teams de index of the OBS virtual camera is 1 or 2, and my webcam is 0. Why can't I use my virtual camera via plus to load into slicer. For "DeviceIndex=0" it works fine, but for "DeviceIndex=1" I get a problem that it says:
"
Connection failed!
Please select another device set and try again!
"
My xml file:

<Device
  Id="VideoDevice_0"
  Type="OpenCVVideo" 
  RequestedCaptureApi="CAP_DSHOW"
  FrameSize="1280 720"
  DeviceIndex="0"
>
  <DataSources>
    <DataSource Type="Video" Id="Video_0" ImageType="RGB_COLOR" PortUsImageOrientation="MF"  />
  </DataSources>
  <OutputChannels>
    <OutputChannel Id="VideoStream_0" VideoDataSourceId="Video_0" />
  </OutputChannels>
</Device>
