Rotate video adding black bars with ffmpeg
13 février 2016, par MrMoogI have a lot of mp4 full hd videos made with a smartphone that looks rotated 90°.
These files have proper rotation metadata and they plays correctly on VLC or other desktop mediaplayers, but I want to display them on my dvd player that does not handles mp4 metadata.
So I tried to transpose with ffmpeg but I obtain 1080x1920 files, resolution obviously not recognized by tv/dvd-player.
How can I transpose, resize and add black side (left/right) bars of the correct dimensions to get "correct" 1920x1080 videos ?
