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

    23 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 with filter complex and to reduce the size I used frame per second.

    "ffmpeg -i
    RM356ce8c15f47cb07b7af885fd718a39f/final/RM356ce8c15f47cb07b7af885fd718a39f.mp4 -vf scale=1280:480 -filter:v fps=fps=30 E :\test\routes\public\assets\downloads\RM356ce8c15f47cb07b7af885fd718a39f/final/RM356ce8c15f47cb07b7af885fd718a39f.mp4"

    Only ’-vf fps=fps=30’ read, ignoring remaining -vf options : Use ’,’ to separate filters

  • Concatenate chunk containg headers to another chunk in h264

    18 novembre 2014, par Ortixx

    I’m trying to extract thumbnails from a torrent stream by downloading the first couple of chunks to get the headers, another set of chunks from the middle and then concat them to have a single video file.

    For this I’m using nodejs but I’m having trouble with the concatenation part. Obviously the headers include the length of the video so if I simply concat another chunk to the end of the headers chunk, it won’t work.

    In other words, I have 2 chunks of a video file : The first one contains the headers and some material and the other one is fully composed of a video stream. I want to combine the two to form a single video file
    So my question is how can I make this work properly if at all ?

  • Add an image behind a video file (.mp4) in python

    12 avril 2020, par George Lua

    I am attempting to add an image behind a video using moviepy and cannot come up with any way to do it. My image dimension is (1080 x 720) and my video dimension is (200 x 200). I am trying to put the video file on top of the image file, place it in the midlle and export the final video with the dimensions of the image. This is a visual representation of what I am trying to achieve :

    



    View image

    



    I tried doing this with the following code, but could not manage to get it to work. Any help is seriously appreciated :)

    



    import moviepy
import moviepy.editor as mp

video = mp.VideoFileClip("/media/pi/vid.mp4")

logo = (mp.ImageClip("/media/pi/pic.png"))

# Preferably I would want the image to be the same duration as the video file. 
# The following was just for testing.
final = mp.CompositeVideoClip([video, logo.set_duration(3)])
final.write_videofile("test.mp4")
