  • 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.

  • How to merge list of videos with frame specifiec order using ffmpeg ?

    9 décembre 2015, par Il'ya Zhenin

    I have a list of files :

    even_0.avi
    
odd_0.avi
    
even_1.avi
    
odd_1.avi
    
...
    
even_n.avi
    
odd_n.avi

    And I want to merge them in a single video file in such a way, that zero frame would be taken from even_0.avi, first frame from odd_0.avi, second - from even_0.avi and so on.

    And if all frames in even_0.avi are taken, then next frame we will take from even_1.avi, next from odd_0.avi, next again from even_1.avi. Basically, when one video ends, we just start taking frames from the next video with prefix "even_" or "odd_".

    I just started using ffmpeg, know, how to simply merge videos, change resolution, fps and so on, but this is beyond my power, so, please, help.

  • Generate and concatenate videos from images with ffmpeg in single command

    17 août 2022, par YulkyTulky

    My goal is to generate a video from images. Let's say I have 2 images 1.png and 2.png.

    &#xA;

    I can do

    &#xA;

    ffmpeg -loop 1 1.png -t 3 1.mp4&#xA;

    &#xA;

    ffmpeg -loop 1 2.png -t 5 2.mp4&#xA;

    &#xA;

    to create a 3 second video from the first image and 5 second video from the second image.

    &#xA;

    Then, I merge the two videos using

    &#xA;

    ffmpeg -i 1.mp4 -I 2.mp4 -filter_complex "concat" final.mp4 &#xA;

    &#xA;

    to create my final 8 second video.

    &#xA;

    This process seems extremely inefficient, and I feel I do not have to use all this processing power+disk reading/writing to create 2 intermediary video files when I only want the one final video.

    &#xA;

    Is there a way to execute this entire process in one ffmpeg command (efficiently) ?

    &#xA;
