    Description

      MacOS 14.3

      Qt Creator 12.0.1

      Qt 6.7.0-beta2

      Device: Samsung Galaxy S22 / A13.0

      Steps to reproduce:

      1. Run example app on Android device - https://doc.qt.io/qt-6/qtmultimedia-camera-example.html
      2. Go to File > Change settings and select very high resolution (for me it was YUV420P 3840x2160 30FPS), but it happens with a format bigger than 1920x1080.
      3. Start recording the video, pause the video, then stop it.
      4. Repeat step 3 several times if it doesn't crash immediately

      Expected: The video recording is started and is stopped. No crash.

      Actual: The app crashes.

      Reproducibility:  100%
