问题 I'm generating an app preview video to send to the AppStore. Depending on the device type, the AppStore requires certain video resolutions. I have a main video, with resolution 1920x1080, which I was able to upload. I need to generate another video with the resolution 1920x886 for supporting 6.5" devices, so I used the following command to perform the scaling: ffmpeg -i video_1920_1080.mp4 -vf scale=1920:886 -c:a copy video_1920_886.mp4 If I get the info for the generated video using ffmpeg
