   process the video frames using QAbstractVideoFilter and are not GPU
   based.
 - QCamera's viewfinder capabilities functions now report correct values
   when filtering by pixel aspect ratio.
 - [QTBUG-46359] fixed crash after using moveToThread() on a QSoundEffect.
 - [QTBUG-47205] fixed VideoOutput (QML) rendering frames from the wrong
   source when having multiple VideoOutputs using different sources.
 - [QTBUG-47630] fixed Camera.supportedViewfinderFrameRateRanges() (QML)
   returning incorrect values when the argument is not of type 'size'.
 - [QTBUG-47859] fixed crash when using Radio.radioData (QML) without
   a radio backend available.
