...to a video using ffmpeg
ffmpeg version 2.2.3 Copyright (c) 2000-2014 the FFmpeg developers built on Apr 20 2015 13:38:52 with gcc 4.8 (Ubuntu 4.8.2-19ubuntu1)
configuration: --prefix=/home/myUsername/usr/local --enable-nonfree --enable-gpl --enable-pic --enable-shared --enable-libx264 --disable-vaapiAccording to some answers here on stackoverflow I wrote the following bash script :
#!/bin/bash
while read p; do
cd "$p"
ffmpeg -f concat -i "allImgNames.txt" -framerate 30 -c:v libx264 -profile:v high -crf 20 -pix_fmt yuv420p output.mp4
cd -
done < folderNames.txtwhere
allImgNames.txt
is a text file containing all the image names.The strange thing is that it works for a few videos but for the rest of the filelist it fails saying
allImgNames.txt: No such file or directory
, which is not true. I checked all paths several times. Also I can execute theffmpeg ...
command above manually without problems.
I don’t know what I’m doing wrong. All file / folder names are normal (no special characters). Maybe I don’t understand enough about bash or ffmpeg. -

Evolution #3587 (Nouveau) : Intégrer le plugin upload HTML5 dans SPIP
9 novembre 2015, par realet RealETJ’utilise avec bonheur depuis mai 2015 ce plugin : http://contrib.spip.net/Formulaire-d-upload-en-html5
Il permet :
- de glisser/lâcher des fichiers pour les téléverser sur le serveur
- il permet de le faire pour plusieurs fichiers à la fois !
- un clic lance la boite de dialogue de sélection de fichiers classique (mais avec la possibilité de choisir plusieurs fichiers)
- le téléversement est animé avec une barre de progression (et si c’est une image, une version miniature)
Bref, c’est une série d’amélioration visuelles et fonctionnelles qui sont :
- utilises
- ergonomiques
- conviviales
- immédiatement visible
- et intéressant à annoncer comme évolution de SPIP
De plus, sous le capot, ça utilise les mécanismes natifs de SPIP pour l’upload, donc, la sécurité native de SPIP.
