  • 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.

  • Empty line output while using Popen with ffmpeg

    27 mai 2019, par Elena_Ouyangmeng

    I’m trying to get information output from the command :

    ffmpeg -i 2019-04-22_16-45-14.mp4 -loop 1 -i image.png -an -filter_complex "blend=difference:shortest=1,blackframe=99:32" -f null -

    When trying this command in command line - the info is there, but when I try to use Popen - nothing (None, None)

    I’ve tried subprocess, and tried os.popen earlier.

    command = 'ffmpeg -i 2019-04-22_16-45-14.mp4 -loop 1 -i image.png -an -filter_complex "blend=difference:shortest=1,blackframe=99:32" -f null -'
    
subproc = subprocess.Popen(command.split(' '), shell=True)
    
x = subproc.communicate()
    
print(x)
