  • 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.

  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • writing simple linux bash program to trim video using ffmpeg [closed]

    12 août 2020, par feri ariyatmoko
      


    1. I know I can trim video using ffmpeg without re-encoding it using this following command :ffmpeg -i 'inputvideo.mp4' -vcodec copy -acodec copy -ss 00:09:33 -to 00:11:53 'output.mp4'

      


      2. 


    2. I've tried that command, it worked like a charm.

      


      3. 


    3. Since I will trim a lot of videos, I think it's better if I have a simple bash program to do it.

      


      4. 


    


    This is what the program should do :

    


      

    1. I use ubuntu, so the program should be written for linux system

      2. 


    2. I execute the program : ./videotrimmer.sh inputvideo.mp4 outputvideo.mp4

      3. 


    3. The program asks the starting time and the time it ends.

      4. 


    4. I enter the times.

      5. 


    5. And done !

      6. 


    


    Example :

    


      

    1. I want to trim the first 3 secs of a 10 secs video named videofile10secs.mp4. The file name of the trimmed video is videofile3secs.mp4

      2. 


    2. ./videotrimmer.sh videofile10secs.mp4 videofile3secs.mp4

      3. 


    3. The program asks the times. I input "00:00:00" and "00:00:03"

      4. 


    4. I press the return key.

      5. 


    5. Done. I should have a new file videofile3secs.mp4.

      6. 


    


    How to write that ? Any help will be highly appreciated.

    


  • Change the framerate of a video including audio without re-encoding using ffmpeg

    12 août 2018, par Trojaner_

    I have a 30.02 FPS .mp4-video and I’m trying to convert it to 30 FPS. I found this question but if I try the method like described in the first answer the audio gets lost because the video is getting converted in a .h264-file which can’t contain audio as I read here.

    (I’m sorry if i’ve got issues with the english language, it isn’t my mother language)

    EDIT : Here goes the content I enter in the terminal and the output that returns

    Input : ffmpeg -y -i 01.mp4 -f h264 -c copy temp1.h264

    Output : (I replaced the real paths with path\to\...)

  • Can FFmpeg crop gif image within 1 second ?

    1er septembre 2021, par jeongbalmountain

    I am developing an iOS application about gif.

    


    But I have a problem with gif cropping. Cropping gif spends so many times with FFmpeg.

    


    Is there a way to reduce the time to crop gif less than 1 second ? (with ffmpeg)
