    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 (...)

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • ffmpeg streaming multiple avi files as created

    2 janvier 2013, par aboredprogrammer

    Backstory :
    I have a VB.net program (that is using a much older COM object accessing a DVR) to create sequentially numbered AVI files each 15 seconds in length. A new AVI is created every 15 seconds with the most recent 15 seconds of video in it. I know the exact datetime that correlates to each file. So files may be named (20121008-133445.avi, so yyyyMMdd-hhmmss.avi).

    Question : Using ffmpeg/ffserver (preferably but I'm open), how can I create a stream such that when a person accesses it that they are presented a continuous video that starts at a position that is as recent as possible and continues to stream the avi files as they are created ?

    I don't have a problem shipping these files off to a Linux box via a samba share (or have the linux box access a share on the windows box) if Linux is more capable. I am however stuck with Windows for the actual generation of the original AVI files.

    The ultimate goal is to be able to view these streams on an iPad, but that process seems pretty well documented elsewhere.

    I found a question that reads similar to my needs but didn't seem to go anywhere : FFmpeg make mpeg2 ts without discontinuity

    Thanks in advance !

  • How to tell if ffmpeg errored or not ?

    12 juin 2015, par dvdmn

    The Situation :
    I’m using ffmpeg (via .net) to save video files. I can get the output from ffmpeg but I dont know how can I customize the output to have better result.

    My Problem :
    My problem is, there is no certain difference between successful and failed operation.

    last line of success :

    video:1006kB audio:134kB subtitle:0 global headers:0kB muxing overhead 0.943510%

    last lines from fails

    c :\x\test-9-8/30/2012-9:29:56-AM.mp4 : Invalid argument

    rtmp ://cdn.tv/cdn-live39/definst/stream01 : Unknown error occurred

    My Question :
    Is there an option (or command line parameter) to add some sort of return code (200 : success, 500 : error, etc)

    Thanks !

    PS : I saw this topic How to tell if ffmpeg errored ? but there is no number before/after last line. I think the last version doesnt have number anymore.

  • ffmpeg time unit explanation and av_seek_frame method

    3 septembre 2013, par user325320

    What does time_base mean in ffmpeg ? document(here) says it is "frames per second".
    and I see in a real example that :

    AVFormatContext->streams[video_index]->time_base == 1 / 30000

    But video's AVCodecContext->time_base == 1001 / 60000

    This makes me quite confused, and I don't understand them.

    The second question is about av_seek_frame method.
    If seeking via time stamp (last parameter is AVSEEK_FLAG_BACKWARD or 0),
    the seek is started from current position read by av_seek_frame ?
    or from the start of the file ? or from the start position of decoding after last av_seek_frame call ?
