  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    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 do I get ffmpeg to concat 1 second from a list of files ?

    13 juin 2023, par Stephen Fluin

    I have about a thousand video clips and I've got ffmpeg and an ffmpeg file list setup like this :

    



    file /path/to/1.mp4
file /path/to/2.mp4
...
file /path/to/1000.mp4


    



    I want to concatenate the first second of each clip into an output clip. I've experimented with duration and outpoints specified in the file list, but neither seems to do what I want.

    



    Here's the documentation I've read which I found unclear and lacking an example using the full API : https://ffmpeg.org/ffmpeg-formats.html#concat

    



    Here's the closest I've come (concat the entirety of all files at 100x speed) :

    



    ffmpeg -f concat -safe 0 -i ~/glass-videos.ffmpeg.txt -filter:v "setpts=PTS/100" -an output.mp4

    


  • Combine many videos in list using FFMPEG

    2 septembre 2022, par anoor1234

    I have a bunch of videos that are MP4s with different FPS, resolution, aspect ratio, basically everything. I'm trying to see if its possible to use FFMPEG to combine them into a single 1080/720 video using a single command, or at least make them all similar format so that combining is easy. Speed and less CPU power would be preferred but I'm in no rush and

    


    I found this command on another stack overflow question :

    


    ffmpeg -i 1.mp4 -i 2.mp4 -i 3.mp4 -filter_complex \
"[0:v]scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:-1:-1,setsar=1,fps=30,format=yuv420p[v0];
 [1:v]scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:-1:-1,setsar=1,fps=30,format=yuv420p[v1];
 [2:v]scale=1280:720:force_original_aspect_ratio=decrease,pad=1280:720:-1:-1,setsar=1,fps=30,format=yuv420p[v2];
 [v0][0:a][v1][1:a][v2][2:a]concat=n=3:v=1:a=1[v][a]" \
-map "[v]" -map "[a]" -c:v libx264 -c:a aac -movflags +faststart output.mp4


    


    The problem is that I have more that 3 videos to combine and I don't know how to work this command with more, I have an entire list of videos in a list.txt file structured as such :

    


    file './videos/video1.mp4'
file './videos/video2.mp4'
file './videos/video3.mp4'


    


    The code that somewhat worked for me was this

    


    ffmpeg -safe 0 -f concat -i list.txt -c copy output.mp4


    


    It combines the video well and fairly fast but I get weird glitches with the audio and the resolution is weird (I'm hoping for 1920x1080). I suspect this is due to the varying attributes of each video but I'm not sure. I'm familiar with Python but I have found no Python script that can do what I ask. If there any way to combine my list into one video (using FFMPEG or not) reliably ?
