I am trying to crop a portrait video of 1280x720 to 568x320 so that the video will be displayed in landscape view (16:9). I am using the following command
ffmpeg -i VID_1438833296.mp4 -vf crop=568:320:0:0 -c:a copy out.mp4
The video gets cropped properly but when I view it in quick time or Android device it still displays in the portrait mode instead of landscape mode.
The quicktime inspector shows Format size as 568x320 (Landscape) but current size is 350x621 (Portrait):
