      Hi all,

      I found a strange problem with QML Camera. Sometimes the onImageCaptured signal will not be emitted. If that happen, VideoOutput is still working but it won't report any error. Moreover, it won't response to stop() function. The VideoOutput is still working and won't change cameraStatus.

      Anyone got similar issue and have idea to fix it?

      Tested Environment:

      • Qt 5.7 + Android
      • Qt 5.7/5.6 on Mac Book Air (Mac OS 10.11)

      Step to reproduce

      1. Open this example

      http://doc.qt.io/qt-5/qtmultimedia-multimedia-declarative-camera-example.html

      1. Press the "Capture" , then press the frozen photo again.

      Repeat this step for 20~30 times. The problem should happen.
