  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    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.

  • FFMPEG concat videos

    10 juin 2015, par Maverick

    I am unable to concat two videos using FFMPEG. The command fails on the two special videos.

    Video 1 :
    First video is generated from the image using the following command :

    ffmpeg -loop 1 -i 20150608_162807.jpg -c:v libx264 -t 3 -pix_fmt yuv420p out.mp4

    I tried to concat the above video but it did not work so, I thought to add an audio to check if it will work.

    ffmpeg -f lavfi -i aevalsrc=0 -i out.mp4 -shortest -c:v copy -c:a aac -strict experimental silent.mp4

    but even with that it did not work.

    Video 2 :
    Second video is captured from the device camera.

    Both of these videos can be downloaded from here.

    Update 1 :
    The concat protocol doesn’t work with mp4s. So, I tried the other approaches.

    ffmpeg -i input1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
    
ffmpeg -i input2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts 
    
ffmpeg -i "concat:intermediate1.ts|intermediate2.ts" -c copy -bsf:a aac_adtstoasc output.mp4

    but still it didn’t work.

    Update 2 :
    I have also used concat demuxer approach but it did not work as well.

  • ffmpeg Error : Pattern type 'glob' was selected but globbing is not support ed by this libavformat build

    14 septembre 2017, par Aryan Naim

    I’m trying to convert group of ".jpg" files acting as individual frames into 1 single mpeg video ".mp4"

    Example parameters i used :

    frame duration  = 2 secs
    
frame rate      = 30  fps
    
encoder         = libx264 (mpeg)
    
input pattern   = "*.jpg"
    
output pattern  = video.mp4

    Based on ffmpeg wiki instructions at (https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images), I issued this command :

    ffmpeg -framerate 1/2 -pattern_type glob -i "*.jpg" -c:v libx264 -r 30 -pix_fmt yuv420p video.mp4

    But I’m getting this error :

    [image2 @ 049ab120] Pattern type 'glob' was selected but globbing is not 
    
supported by this libavformat build *.jpg: Function not implemented

    Which probably means the API pattern matching commands for my build/version have changed. By the way this my windows 32bit ffmpeg download build (ffmpeg-20150702-git-03b2b40-win32-static).

    How can I choose a group of files using pattern matching using ffmpeg ?
