Loading file with webcam input does not work

[yiids]

Expected Behavior

I create a new mapping using a webcam as input. I save the file. I load the file and it still works

Actual Behavior

I create a new mapping using a webcam as input. I save the file. I load the file, it doesnt seem to understand that its loading a webcam and treats it as a video file, that it can not find. It asks me to locate the file. I click cancel and then manually fill in the device under the Source property. It still does not understand and does not play my camera device.

I am using v4l2loopback devices but I dont think that should have anything to do with the issue.

Steps to Reproduce the Problem

1. add a camera
2. map some shapes
3. save the file
4. exit
5. load the file
