  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.
    If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...)

  • 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.

  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Merge videos and images into a new video in Android [on hold]

    10 septembre 2013, par vijay

    I have to create an android app that is similar to PicPlayPost.

    The app should be able to do the following things :

    • Load images and videos into the corresponding blocks in the frame.

    • Resize the image.

    • Add audio to the block that contains image.

    • Play two or more videos in parallel.

    • Save the whole frame as a video clip.

    I thought of using FFmpeg concatenation for this but it will not play all the videos in parallel.

    I have tried to use FFmpeg with android in my earlier project and ended up with lot of issues when building latest FFmpeg with android NDK.The below link explains the usage of pre-compiled FFmpeg and OpenCV for Android.

    https://code.google.com/p/javacv/#Quick_Start_for_OpenCV_and_FFmpeg

    but i could not find ffmpeg-1.2*.jar there.

    Is there any package to process video and playback in android other than FFmpeg ?

    Thanks.

  • How to output mp4 after concatenation using ffmpeg

    27 août 2019, par Patrick

    I want to merge a couple of mp4 videos (with different fps, heigth, width and bitrate).

    I tried this with a few videos, but it always hides or skips some video files from the input.txt.

    How can I correctly merge those mp4 files ?

    Thank you !

    My command :

    ffmpeg, "-f", "concat", "-i", "concatfile.txt", "-c:v", "copy", "-sn", "-y", "merged_video.mp4", "-max_muxing_queue_size", "1024"

    -> the video does not play correctly

    EDIT :
    i now output the information of each video in concat.txt_

    Could be the issue, that the last mp4 has mono audio ?

  • ffmpeg, stereo + 5.1 surround, and YouTube's "Recommended upload encoding settings"

    31 juillet 2021, par CoreyVidal

    I'm trying to make sense of something YouTube has listed on their recommended upload encoding settings for the best possible quality. Here's the link : https://support.google.com/youtube/answer/1722171#zippy=%2Caudio-codec-aac-lc

    


    Specifically this line :

    


    

      

    • Channels : Stereo or Stereo + 5.1

      • 


    


    


    I'm Googling for "Stereo + 5.1" and anything to do with ffmpeg but I can't seem to find much of anything.

    


    I have trailers with surround audio I need to export for a client for YouTube.
