jeelizFaceFilter: iOS 13 / Android v9 camera resolution flipped and causes zoom-in effect

Describe the bug On iOS 13 it seems like Safari automatically flips cameraWidth and cameraHeight if the camera is opened in portrait mode. Because JeelizResizer is doing a flip as well this causes a double flip and due to that a wrong camera resolution. Which leads to a zoom-in effect.

To Reproduce Steps to reproduce the behavior:

1. Start Jeeliz with a Resizer

  startJeeliz() {
    window.JeelizResizer.size_canvas({
      canvasId,
      isFullScreen : true,
      callback     : (isError, videoSettings) => {
        this.initFaceFilter(videoSettings)
      },
      onResize: () => {
        if (threeCamera) {
          threeCamera.aspect = CANVAS.width / CANVAS.height
          threeCamera.updateProjectionMatrix()
        }
      }
    })
  }

1. Pass the video parameters to init

  initFaceFilter(videoSettings) {
    console.log('VideoSettings', videoSettings)
    window.JEEFACEFILTERAPI.init({
      canvasId,
      videoSettings,

1. Run the app and open the camera stream
2. See that the video appears to be zoomed in

Expected behavior Camera is opened with correct resolution
