Video aspect ratio still incorrect with some resolution settings

[ktprograms]

Describe the bug
Followup from #48, It works fine when not setting any resolution (so letting it use the default of 640x360), but when I add cameraSource.resolution = Size(480, 640) in the onResume() method of the example app's CameraTabFragment, both the view on the phone and the stream are stretched.

To Reproduce
Steps to reproduce the behavior:

1. Add cameraSource.resolution = Size(480, 640) in the onResume() method of the example app's CameraTabFragment
2. Hold phone in portrait mode
3. Tap publish
4. Open Stream
5. Both the video on the phone and the stream are stretched.

Expected behavior
Video should not be stretched
