  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Wrong video duration reported after concatenating video files in BASH script

    13 novembre 2012, par Benjen

    I am trying to merge three video files (each 16 seconds long) into one file using ffmpeg. Since they are in mpeg format I am simply trying to concatenate them into one file using cat command. The problem is that when I run the resulting file (video.mpg) it is reported as being 16 seconds long (same as the first concatenated video). Interestingly when I play the file in VLC, I can watch the whole 48 sec of video, even though the video progress bar also only reports up to 16 secs.

    It almost seems like the file "properties" (e.g. duration, etc) are not updated after the additional two videos are added using the cat command.

    Would appreciate any suggestions on how I might solve this.

    The following is the relevant section of the BASH script I have created :

    mkfifo intermediate1.mpg
    
mkfifo intermediate2.mpg
    
mkfifo intermediate3.mpg
    
ffmpeg -i "./tmp/final01.mp4" -qscale 1 -y intermediate1.mpg < /dev/null &
    
ffmpeg -i "./tmp/final02.mp4" -qscale 1 -y intermediate2.mpg < /dev/null &
    
ffmpeg -i "./tmp/final03.mp4" -qscale 1 -y intermediate3.mpg < /dev/null &
    

    
echo "[audioforge] Stitching files "
    
cat intermediate1.mpg >> ./tmp/video.mpg
    
cat intermediate2.mpg >> ./tmp/video.mpg
    
cat intermediate3.mpg >> ./tmp/video.mpg
    

    
# Convert back to mp4 format.
    
ffmpeg -i "./tmp/video.mpg" -qscale 1 -y "./tmp/video.mp4"
