      When i launch the project, i get two message boxes of "No camera source available".

      In the "devices" menu, both my cameras are correctly listed, but both produces the "No camera source available" when trying to start them.

      I've tried installing all the packages mentioned in QTBUG-39798, but it still doesn't work.

      In addition, the following messages are listed:
