  • 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" (...)

  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • MediaSPIP Core : La Configuration

    9 novembre 2010, par

    MediaSPIP Core fournit par défaut trois pages différentes de configuration (ces pages utilisent le plugin de configuration CFG pour fonctionner) : une page spécifique à la configuration générale du squelettes ; une page spécifique à la configuration de la page d’accueil du site ; une page spécifique à la configuration des secteurs ;
    Il fournit également une page supplémentaire qui n’apparait que lorsque certains plugins sont activés permettant de contrôler l’affichage et les fonctionnalités spécifiques (...)

  • Audio HLS with metadata on Mac from directory of mp3 files ?

    2 février 2017, par eagspoo

    I’m trying to create HLS output (m3u8 file + many .ts files) from a list of mp3 files where the mp3 id3 metadata is preserved in the HLS output.

    I’ve been trying ffmpeg like this :

    ffmpeg -f concat -i list.txt -hls_init_time 2 -hls_time 2 out.m3u8

    where list.txt contains :

    file 01.mp3
    
file 02.mp3
    
file 03.mp3
    
file 04.mp3
    
file 05.mp3
    
file 06.mp3
    
file 07.mp3
    
file 08.mp3
    
file 09.mp3
    
file 10.mp3

    The result is a single out.m3u8 file and a single very large out0.ts file. I was expecting about 1500 ts files and an m3u8 file that contains the last 5 ts files.

    I’m completely new to ffmpeg and honestly I don’t want to learn it in depth right now.

    Does anyone know how to do this either with ffmpeg or otherwise ?

    avcodec/vc1 : change the internal ordering of blocks within a macroblock

    The overlap filter needs to cover a full macroblock vertical edge when the
    
FIELDTX value for two neighbouring macroblocks is not equal. By changing
    
the internal ordering of the blocks from row major to column major, we do
    
not need to reinterlace a FIELDTX coded macroblock before running the overlap
    
filter.

  • ffmpeg called from python random failure

    9 juillet 2017, par Jim Weisbin

    Python 2.7.1 on Mac OS X 10.12.5, ffmpeg 3.3.2 (installed with Brew).

    ffmpeg is called in a loop though thousands of Apple Lossless files, converting to mp3 and tagging.

    thecall = '/usr/local/bin/ffmpeg -hide_banner -loglevel error -i ' + <path to="to" m4a="m4a" file="file"> + ' -i ' + <path to="to" artwork="artwork"> + ' -map 0:0 -map 1:0 -id3v2_version 3 -map_metadata -1 -metadata album="xxx" -metadata artist="xxx" -metadata comment="Cover (Front)" -f mp3 -b:a 128K ' + <path to="to" mp3file="mp3file">'
    
</path></path></path>

    os.system(thecall)

    this works perfectly from the command line, and also works from Python most of the time, but randomly fails with the message

    [alac @ 0x7fc888858800] invalid samples per frame : 0
    Error while decoding stream #0:0 : Invalid data found when processing input

    What’s strange is that on the files it failed on, if I run it from the command line it succeeds. I tried putting in time.sleep(5) but no change. And the failures are not always on the same file, so it seems like it’s a memory or threading issue. I also tried calling with subprocess() instead, no change.

    Any help would be appreciated.
