Question about the inverted aspect ratio of saved videos

[oxyhexagen]

Thank you for sharing this repo with those who hasn't developed android app like me. There's a simple question, regardless of the aspect ratio set in the app or hardcoding (e.g. 1920x1440), the saved videos always have width and height flipped (1440x1920). I'm not sure if this is related to the vertical UI preview. Could you please let me know which part of the code I should modify if I want the saved videos to match the set aspect ratio without rotation? I only found this one relevant variable mSensorOrientation. Thanks a lot.
