  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • How to concatenate two or more videos with same width and different height in FFMpeg and to maintain the same aspect ratio ?

    25 octobre 2019, par Aarwil

    I have five video parts to concat all. Each five videos are in the same width and height. The second part is the hstack of another 2 videos and the third part is the hstack and vstack of another 3 videos. While concat all the five video parts the aspect ratio is not maintaining in the final video. Since I am new to ffmpeg help me to sort out the problem

    I have tried with the command in my final with filter complex and to reduce the size I used frame per second.

    "ffmpeg -i
    final.mp4 -vf scale=1280:480 -filter:v fps=fps=30 finalNew.mp4"

    but nothing worked.
    Also help me to use hstack with scaling, to maintain the aspect ratio for the second part on below command

    Command : ffmpeg -i vid1.mkv -i vid2.mkv -filter_complex "[0:v]scale=-1:480[v0] ;[0:v][1:v]hstack=inputs=2"vid3.mkv

    Images

    second part

    third part

    videochunks

    I have console the info of my video
