QML Camera - imageCaptured signal is not emitted

benlau

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

Open this example

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

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

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