  • Possibilité de déploiement en ferme

    12 avril 2011, par

    MediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
    Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

  • Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

    12 avril 2011, par

    La manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
    Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

  • Combining Video and Audio of different length in bulk

    25 mai 2017, par user2981223

    I am going through a tv series right now and editing the files to be to my liking. I have one set which has the video I want and one set that has the audio. I have a batch file that I can run that takes the video from every file in folder "A" and the audio from every file in folder "B" and outputs it to a folder named "output." But with this particular series, that is only half of what I need done.

    At the end of every episode of the files in the "B" folder there are some extra things. What I would like to do is take the audio and video from "A" and the audio from "B", combine it all into one file and also take the "A" and "B" files, compare the time stamps, and add the extra video from "B" to the output file.

    Let me put it another way. Let’s say "A" is 1080p with Japanese audio and is 20 minutes long. Let’s say "B" is 720p with English audio and is 23 minutes long. I want the whole 1080p video with both audio tracks, plus the 720p video spliced onto the end. Both files start at the same spot so syncing isn’t an issue. The issue is that the difference in time is different for every episode. So some episodes are 3 minutes longer, some only 30 seconds. Is there a way to make ffmpeg or another tool look at the difference in times and just add the excess to the output file ?

    Sorry for being long winded. Thanks for any help and guidance.
