  • 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.

  • FFMPEG/AVCONV Video flipping is taking long time, How can we reduce the process time ?

    10 juillet 2014, par Prasanth P

    I am trying to flip video using FFMPEG/AVCONV on Ubuntu. When it flips 1 minute video, it takes 12 to 40 seconds for processing and conversion.

    ffmpeg is deprecated and avconv is being using instead.

    Video file size : 7mb, Duration : 1 minute

    avconv -i 1_1.mp4 -c:v libx264 -c:a copy -vf "vflip" conv.mp4

    and the result is :

    avconv version 0.8.12-4:0.8.12-0ubuntu0.12.04.1, Copyright (c) 2000-2014 the Libav developers

  • ffmpeg says "No JPEG data found in image" when reading image paths from Linux pipe

    18 septembre 2021, par user16945608

    I'm trying to convert a set of pictures into a video, and I want to read the file paths of the pictures from the pipe. The command I would like to run looks like this :

    


    find dir/*.JPG | sort | ffmpeg -f image2pipe -r 1 -vcodec mjpeg -s 6000x4000 -pix_fmt yuvj422p -i - -vcodec libx264 -s 1080x720 -r 20 -pix_fmt yuv420p out.mkv

    


    But I keep obtaining the No JPEG data found in image error. Here is the full log :

    The pictures are in the following format (with mediainfo) and the filenames are in the form DSC_1234.JPG :

Bit depth                                : 8 bits
Compression mode                         : Lossy


    


    Also, I would like to avoid using a solution without piping the paths (with -f image2 -i DSC_%04d.JPG for example). Do you have any idea what's happening ?
