I discovered this issue while using a tip from here: http://stackoverflow.com/a/27768317/1003916
I have a video that was recorded on a cell phone vertically. When played back on a computer in VLC/mpv/SMPlayer, the video is always sideways, in landscape orientation.
When I use FFmpeg to apply a rotation flag to the video as suggested in the stackoverflow post, SMPlayer does indeed display the video rotated, however it does not adjust the aspect ratio and the video plays back squished and still in landscape orientation.
I am using
mpvfor playback.. when I open the file directly from mpv without SMPlayer, the rotated video plays back correctly rotated and in portrait orientation. VLC also plays back the video correctly. SMPlayer is the only player I have this issue with.
$ ffprobe -v quiet video.mp4 -show_streams|grep rot TAG:rotate=90
