  • 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 (...)

  • 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" (...)

  • RTP Streaming with ffmpeg : server streaming, client failing

    27 novembre 2013, par Christoph Kuhr

    I compiled ffmpeg and x264 myself.

    x264 version :

     #define X264_REV 2377
    
 #define X264_REV_DIFF 0
    
 #define X264_VERSION " r2377 1ca7bb9"
    
 #define X264_POINTVER "0.140.2377 1ca7bb9"

    ffmpeg version : 0.11.4
    ffmpeg configuration :

     --enable-x11grab --enable-pthreads --enable-libfaac --enable-libxvid --enable-libx264 --enable-libv4l2 --enable-libmp3lame --enable-libpulse --enable-gpl --enable-nonfree --disable-yasm

    streaming server call :

    ffmpeg -f x11grab -s 1600x900 -framerate 50 -i :0.0 -vcodec libx264 -threads 4 -preset ultrafast -crf 0 -q:v 1 -b:v 8M -an -f rtp rtp://192.168.188.30:8710
    

    
...
    

    
 Output #0, rtp, to 'rtp://192.168.188.30:8710':
    
  Metadata:
    
    encoder         : Lavf54.6.100

b=AS:8000
    
a=rtpmap:96 H264/90000
    
a=fmtp:96 packetization-mode=1

    Everything looks good so far...

    Now the problem.
    I create foo.sdp from the SDP output of the server and try to playback the stream with ffmpeg ffplay foo.sdp. ffplay fails with the following error :

     [sdp @ 0x7f5e0c0008c0] decoding for stream 0 failed
    
 [sdp @ 0x7f5e0c0008c0] Could not find codec parameters (Video: h264)
    
 [sdp @ 0x7f5e0c0008c0] Estimating duration from bitrate, this may be inaccurate
    
 gameserver.sdp: could not find codec parameters

    If I try the same with VLC, it also fails, but with the different error :

      [0x7f3278c045b8] live555 demux error: no data received in 10s, aborting

    Look like different reasons. But I could not solve either. Does anyone have a clue ?

  • MIME type for transcoded stream

    11 septembre 2012, par Matt Joiner

    I wish to determine the MIME type of the contents of a pipe. The pipe is outputting a transcoded video stream, so there is no corresponding file extension.

    Can I determine the MIME type in these circumstances using say ffprobe -i pipe:0 or some equivalent ? Is there a canonical mapping of codecs or container formats to MIME type ?

  • PHP imagick equivalent of -define png:color-type=6

    5 avril 2016, par user1661677

    I’m needing to save my PNG files with a different color type so ffmpeg can process them correctly. I’m using the PHP library for imagemagick, and I’m trying to figure out how to implement the following (command line) in imagick PHP :

    -define png:color-type=6
