    Description

      MacOS 14.4

      Qt Creator 13.0.0

      Qt 6.7.0

       

      Steps to reproduce:

      1. Open any camera example (widgets or QML camera)
      2. Record a video with connected FHD webcam (USB).
      3. Play the video.

      Expected: The video shows what has been recorded.

      Actual: The video shows a green flashing nose - it looks like corrupted (See attached) and the following logs start to continuously appear in the console:
