  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • 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 (...)

  • Android ffmpeg library use

    26 août 2016, par m.skolimowski

    I’m pretty new to use of ffmpeg library. I used this http://writingminds.github.io/ffmpeg-android-java/ to add library to my android studio project. It works well when I run the command -version or -devices
    However when I try any command with -i beginning like for example -i video.avi I get the error :

    Am I doing something wrong ? ANybody have idea why basic command like "-i" doesnt work ?

  • FFMPEG creates incorrect Source duration

    4 août 2016, par Byron Whitlock

    When transcoding movies from an AVI to mp4 sometimes FFMPEG sets the "Source Duration" incorrectly.

    This messes up playback on IOS devices. Specifically, it causes the video to cut out at "Source duration" while the audio still plays.

    enter image description here

    FFMPEG output transcode doesn’t’ show anything odd at all. Looks normal, no errors or warnings.

    • Can I force FFMPEG to never add the "Source Duration" metadata ?
    • How do I edit the track metadata shown by mediainfo ? I tried Mp4box, and a few others, but I can’t seem to figure out how to edit track level metadata.

    Thanks.

    Edit

    This has something to do with data, when I run this command (cut at 10 minutes)

    ffmpeg.exe -i CI.mp4 -ss 00:00:00 -t 00:08:00 -vcodec copy  -map_metadata 0 -acodec copy CI2.mp4

    Mediainfo shows

    Duration                    : 9mn 49s
    
Source duration             : 2mn 40s

    When I run this one (18 minutes)

    ffmpeg.exe -i CI.mp4 -ss 00:00:00 -t 00:18:00 -vcodec copy  -map_metadata 0 -acodec copy CI2.mp4

    Mediainfo shows

    Duration                    : 17mn 49s
    
Source duration             : 3mn 30s

    How can I edit the metadata directly
