After rotation video frame will be square. Not show proper as per aspect ratio

[ghost]

@MasayukiSuda I have rotated video frames but it should not display properly. I have used video of 16/9 aspect ratio. Then apply filter on it. It will show proper for 0 and 180 roation. But if rotation will be 90 or 270 then frame size is not proper. I did not rotate GPUPlayerView. But I rotate frames while draw it. But After rotation frame width will change. I have checked aspect ration after rotation, it is proper. If aspect ration is proper then why frame is not show proper.

Please guide me.
