    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Android Live Streaming with MediaCodec and ffmpeg ? [on hold]

    15 mars 2016, par Chuong Nguyen

    I’m using Android MediaCodec to record video and audio into ByteBuffer (H264, AAC). All I need now is how to use ffmpeg (or librtmp) to send data to server using RTMP protocol.

    Is there any clear document how to use these API or an example about ffmpeg rtmp ?
    I’ve searched for days but found nothing. Anyone can help me ?

    Thank you !

    P/S I’m looking for example or document about RTMP in ffmpeg, not JavaCV

  • Couldn't find platform family in Info.plist for dylib

    7 avril 2016, par user2331687

    enter image description here

    I have developed a App (Mac OS) and I want release it to Mac App Store, and my App use the FFMPEG library, so there are many .dylib (as you can see, for example, libSDL-1.2.0.dylib), when I upload my App, and I got this error, I have googled several days, but I don’t know how to add the "platform family" to a .dylib, since the dylib is build from command line. Can anyone help me to solve this problem, thanks very much !

  • Ffmpeg avs to avi lossless conversion

    21 février 2016, par Piotr

    How to convert avs (Avisynth file) to avi without loss of quality ?

    Firstly, I’m changing avs to 264 :

    ffmpeg -i "Source.avs" -c:v libx264 -preset veryslow -crf 24 "Output.264"

    Secondly, I’m trying to convert 264 to avi :

    ffmpeg -i "input.264" "output.avi"

    Final avi should have almost 200MB, but has only 2MB. 264 file has almost 150MB, so it should be good. I think that I should use some codec in second command, but I don’t know which. I’m trying to change this for a few days, but without effect.

    Or maybe there is a way to lossless conversion without 264, only avs to avi ?

    Thank you for your help.

    Edit :

    Thank you for answers. Unfortunatelly, both methods fail.
    First gives me a video, which is blurry and I can’t see anything on it.
