ffmpeg resizing video puts it at wrong resolution
16 décembre 2015, par agmcleodI have a 1080p video that i’m trying to resize for an iOS app upload. So i tried scaling it to the iPhone 6 resolution of 1334x750 :
ffmpeg -i WrathTrailer.mp4 -strict -2 -vf scale=1334:750 WrathTrailer1334x750.mp4
The output file comes to 1333x750. iTunes connect won’t accept it. Any ideas ?
