Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

How can I concatenate different videos while maintaining the original display and aspect ratio ?
11 décembre 2019, par LaurenIs it possible to concatenate different videos with different aspect ratio into a single video ? And also in the end the final video would maintain the original aspect ratio of each part.
I’ve tried the following FFmpeg command :
ffmpeg -i 1.mp4 -i 2.mp4 -y -filter_complex "[0:v:0] [0:a:0] [1:v:0] [1:a:0] concat=unsafe=1:n=2:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" out.mp4
I’m using unsafe=1 which almost works.
The only issue is that some videos stretch.
So, how can I concatenate different videos while maintaining the original display and aspect ratio ? -
