I can’t figure this one out. I have videos recorded from three different Google Pixel phones. The videos shot in landscape mode are fine but those shot in portrait mode are playing back rotated 90 degrees counterclockwise.
One thing about cell phone videos is that if you start recording in one mode and turn the phone while still recording, it won’t playback correctly. I had two videos like that and I imported them into a video editor to rotate them correctly. They are portrait mode now and look fine on Plex. So, comparing those two videos to all the others, here’s what I found using VLC’s codec information:
Correct portrait mode video:

Two things jumped out at me. The frame rate is slightly different. But what might be at the bottom of this is that the correct video’s orientation is “Left bottom” and the incorrect video’s orientation is “Top left”.
What I think is happening is that when you playback a video that has its orientation as “Top left”, Plex rotates it so that “Top left” becomes “Left bottom”.
Can anyone tell me how to fix?
