How to keep the orientation number(exif) after converting from a video file to a image file by a ffmpeg command
24 novembre 2023, par user27240The command below is working perfectly fine for my environment except it deletes the orientation number (EXIF) of the image file after being converted from a video file.


System info :


- 

- FFmpeg 2.2.2
- CentOS 6 (x86_64)






I'd like to know how to keep the orientation number(exif) of the image with the command line below(it also have to keep the original purpose of its functionality which is to convert a video to a image from one directory to another.). I'd appreciate if anyone could help me out.


for i in /path/to/inputs/*.mp4; do ffmpeg -i "$i" -frames:v 1 "/path/to/outputs/$(basename "$i" .mp4).jpg"; done
