  • How to execute this ffmpeg command for multiple videos is a folder on Linux terminal

    3 février 2023, par average_grad_student

    I'm trying to change the framerate of my video to 15fps and I need to do that for 100+ videos that are in the same folder

    


    For processing a single video I use the following command-
ffmpeg -i input.mp4 -filter:v fps=fps=15 processed/input_15fpst.mp4

    


    How do I do this for multiple videos in the folder and add a suffix _15fps to them ? I'm not very familiar with Linux programming

    


    Thank you so much !

    


    I tried doing this-
    
for f in *.MP4; do ffmpeg -i "$f" -filter:v fps=fps=15 process/"$f"; done

    


    But I want to rename the file as well, how do I change my loop ?

    I am using hiteshsondhi88/ffmpeg-android library to time or cut videos.It works fine for most videos but for some of the videos it fails and give below error especially for videos shared from whatsapp.I am using Environment.getExternalStoragePublicDirectory(
    Environment.DIRECTORY_MOVIES
    ) for storage of videos.Whats does this error means and why i am not able to crop/trim some videos ?

    FAILED with output : WARNING: linker: /data/data/com.peoplecloudlabs.apps.guggu/files/ffmpeg has text relocations. This is wasting memory and prevents security hardening. Please fix.
