  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • 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 (...)

  • Using FFmpeg. How to convert portrait videos to landscape video ? But the orientation of the video is still portrait on the landscape video. How ? [closed]

    9 janvier 2021, par Jefferson Villasan Josol

  • Convert a video with content type video/quicktime to video/mp4 using ffmpeg

    25 juin 2021, par schub

    I have a strange problem. I start with a video file recored with an iPhone. The output is video.mov. I convert this to mp4 using ffmpeg :

    


    ffmpeg -i video.mov -vcodec h264 -acodec aac video.mp4

    


    If I use a tool like exiftool to show the metadata the output for content-type is video/mp4 all seems to be correct. But my backend, which receives the video, uses a library called Apache Tika to extract the content type and the result here is : video/quicktime.

    


    Scala code to retrieve the content type from the file :

    


    // byteArray: Array[Byte]

val tika        = new TikaConfig()
val metadata    = new Metadata()
val contentType = tika.getDetector.detect(TikaInputStream.get(byteArray), metadata)


    


    BTW : If I use a video editing program (DaVinci Resolve in my case) I can load the video, adjust settings and explicitly set the codec to mp4, export the video and then the resulting file works and Apache Tika extract the desired content-type. This is a workaround, but it does not scale and I like to automate this process via ffmpeg.

    


    I'm stuck here. Can anyone give me a hint what I can do ?
