Qualité du média après traitement
21 juin 2013, parLe bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

a command in a script doesn't work when the script is launched by cron
5 mai 2023, par a kWhen I launch the script manually both as a not-root user (with sudo) and as the root, everything work correctly.
When Cron (Cron of the root) launches it, ffmpeg doesn't work (but the others lines of the script work correctly).


#!/bin/bash
log=/var/log/log2/log2.txt

echo ______________ $(date) >> "$log"
echo -n whoami ' ' >> "$log" ; whoami >> "$log"
echo -n pwd ' ' >> "$log" ; pwd >> "$log"
echo "$""USER" = ' ' "$USER" >> "$log"
echo PATH ' ' $PATH >> "$log"
echo -n which ffmpeg ' ' >> "$log" ; which ffmpeg >> "$log"
echo -n whereis ffmpeg ' ' >> "$log" ; whereis ffmpeg >> "$log"

echo "" >> "$log"
echo ls -l "/bin/* | grep ffmpeg" ' ' >> "$log"
ls -l /bin/* | grep ffmpeg >> "$log"

echo "" >> "$log"
echo ls -l "/usr/bin/* | grep ffmpeg" ' '>> "$log"
ls -l /usr/bin/* | grep ffmpeg >> "$log"

echo "" >> "$log"
echo ls -l "/var/log | grep log2" ' '>> "$log"
ls -l /var/log | grep log2 >> "$log"

echo "" >> "$log"
echo ls -l "/var | grep log" ' '>> "$log"

echo "$!"
sleep 5
kill "$!"
exit



The script puts in the file /var/log/log2/log2.txt :


whoami root
pwd /root
$USER = 
PATH /usr/bin:/bin
which ffmpeg /usr/bin/ffmpeg
whereis ffmpeg ffmpeg: /usr/bin/ffmpeg /usr/share/ffmpeg /usr/share/man/man1/ffmpeg.1.gz

ls -l /bin/* | grep ffmpeg 
-rwxr-xr-x 1 root root 284976 mai 18 2022 /bin/ffmpeg

ls -l /usr/bin/* | grep ffmpeg 
-rwxr-xr-x 1 root root 284976 mai 18 2022 /usr/bin/ffmpeg

ls -l /var/log | grep log2 
drwxrwxrwx 2 root root 4096 mai 5 03:22 log2

ls -l /var | grep log 
drwxrwxr-x 16 root syslog 36864 mai 5 00:00 log



I have tried to verify :


- 

- the permissions of the file ffmpeg
- the permissions of the folder where ffmpeg writes to
- the $PATH
- the path of ffmpeg
- the path of the file where ffmpeg should write to

There I included libcurl.Internet says I have to add the following code to ’Makefile’.
INCLUDE = -I/usr/local/include
LDFLAGS = -L/usr/local/lib
LDLIBS = -lcurlThat did not work.
