After change the camera's resolution VideoOutput becomes black.

Sometimes after changing the resolution of the camera the Qml VideoOutput becomes black.

m_resSupport = m_pImgCapt->supportedResolutions(m_encodeSet);
m_encodeSet.setResolution(m_resSupport[Idx]);
m_pImgCapt->setEncodingSettings(m_encodeSet);

Only with stop() and start() the camera again works. But that takes longer and there is no smooth transition anymore.
