La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans 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 (...)

FFmpeg script skips files
15 avril 2014, par ucq52oseI wrote a shell script to convert many video files and save them with something appended to the file name. The script works, but it seems to randomly skip files, and a lot of them.
When I re-run the script, it will convert files it skipped before. How can I get it to stop skipping files ?
workingDir=/home/user/Videos
# get list of files to convert
find /video/folder -iname "*.mp4" > $workingDir/file_list
# convert files
cat $workingDir/file_list | while read LINE; do
# FFmpeg often cuts off the beginning of this line
echo "$(dirname "$LINE")/$(basename "$LINE")"
if /usr/bin/ffmpeg -n -loglevel panic -v quiet -stats -i "$LINE" \
-c:v libx264 -vf scale="trunc(oh*a/2)*2:320" \
-pix_fmt yuv420p -preset:v slow -profile:v main -tune:v animation -crf 23 \
"$(dirname "$LINE")/$(basename "$LINE" \.mp4)"_reencoded.mp4 2>/dev/null; then
echo "Success: $(dirname "$LINE")/$(basename "$LINE")" >> $workingDir/results
else
echo "Failed: $(dirname "$LINE")/$(basename "$LINE")" >> $workingDir/results
fi
doneOne problem seems to be that FFmpeg interferes with the script. The FFmpeg output often cuts off the beginning of the next command, even if the output is not shown. This is demonstrated by the echo line before the if statement, which is often cut off. But even for lines that aren't cut off, most of them will be skipped for no apparent reason.

Recursively running ffmpeg concat script in bash across multiple folders
15 août 2022, par Sam FeldmanI wrote a bash script that concatenates all video files in a folder using ffmpeg. I would like to be able to run this script recursively on multiple folders. My problem has been that I am unable to change into the directory of every new folder to run the script. This is required for my script to work. Does anyone know what I could accomplish this ?


#!/bin/bash

for f in *; do echo "file '$f'" >> files.txt; done
for f in *; do echo "'$f'" >> filesdelete.txt; done
ffmpeg -f concat -safe 0 -i files.txt -c copy "${PWD##*/}".MP4
xargs -I{} rm -r "{}" < filesdelete.txt
rm files.txt
rm filesdelete.txt


I start with the file structure below. The script runs in each subdirectory (dir1, dir2, dir3) and combines the files in each subdirectory into one video. For the script to run, it needs to cd into each directory.


root
├── dir1
│ ├── video1.mp4
│ ├── video2.mp4
│ └── video3.mp4
├── dir2
│ ├── video1.mp4
│ └── video2.mp4
└── dir3
 ├── video1.mp4
 └── video2.mp4


The end result should look like the structure below.


root
├── dir1
│ └── concat.mp4
├── dir2
│ └── concat.mp4
└── dir3
 └── concat.mp4
