  • 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.

    despite solving the problem, I'd be happy with any other solution to compress video to pal-dvd or pal-vcd standard

    


    I tried re-encoding a mpeg-2 video using avconv and/or ffmpeg to target pal-dvd or pal-vcd or even just vcd or dvd.
manpage states option -target as main option :

    


    

        -target type (output)


    


    Specify target file type ("vcd", "svcd", "dvd", "dv", "dv50"). type may be prefixed with "pal-", "ntsc-" or "film-" to use the corresponding standard. All the format options
(bitrate, codecs, buffer sizes) are then set automatically. You can just type :

    


    avconv -i myfile.avi -target vcd /tmp/vcd.mpg

    


    Nevertheless you can specify additional options as long as you know they do not conflict with the standard, as in :

    


    avconv -i myfile.avi -target vcd -bf 2 /tmp/vcd.mpg

    


    


  • Font setting for ffmpeg not working when adding subtitles from .srt file

    29 septembre 2022, par asdfgh

    I've been trying to use the ffmpeg-subtitles
option like this

    


    ffmpeg -i demo.mp4 -vf "subtitles=demo.srt:fontsdir=/usr/share/fonts/truetype/dejavu:force_style='Fontsize=24px,PrimaryColour=&H000000FF,force_style=Fontname=DejaVuSerif'" out.mp4


    


    but it seems to me that some default config file is overriding font argument from command line because it is ignored (the other things like generating video with subtitle and text coloring works fine), as per this line

    


    fontselect: (Arial, 400, 0) -> /usr/share/fonts/truetype/liberation/LiberationSans-Regular.ttf, 0, LiberationSans


    


    no matter what I give as fontsdir or Fontname, ffmpeg always uses LiberationSans. Here is the full output of the command above :

  • FFMPEG command runs in terminal but not by subprocess

    1er septembre 2022, par Basilique

    I am trying to run a bash command using the subprocess module from within python 3.10.

    


    The bash command is :

    


    ffmpeg -framerate 1 -pattern_type glob -i '*.png' -c:v libx264 -pix_fmt yuv420p -vf "crop=trunc(iw/2)*2:trunc(ih/2)*2" out.mp4


    


    In terminal the command runs fine. Here is the output :

    In my python script I tried the following solutions :

    


    video_cmd = """ffmpeg -framerate 1 -pattern_type glob -i '*.png' -c:v libx264 -pix_fmt yuv420p -vf "crop=trunc(iw/2)*2:trunc(ih/2)*2" out.mp4"""

subprocess.run(shlex.split(video_cmd), shell=False, cwd=path_viz, stderr=subprocess.STDOUT, check=True, text=False)

subprocess.run(video_cmd, shell=True, cwd=path_viz, stderr=subprocess.STDOUT, check=True, text=False)


    


    as well as the solution proposed for this similar question

    


    subprocess.Popen(video_cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)


    


    None of them worked. Apparently, the right command is run (output of the check_out function) :

    


    Command 'ffmpeg -y -framerate 1 -pattern_type glob -i '*.png' -c:v libx264 -pix_fmt yuv420p -vf "crop=trunc(iw/2)*2:trunc(ih/2)*2" out.mp4' returned non-zero exit status 1.


    


    the first part of the job (up to Stream mapping:) is done also correctly :

    but it then pops up the following error :

    Any ideas of why this error is produced in python while in terminal it runs fine ? Thank you in advance.
