  • Amélioration de la version de base

    13 septembre 2013

    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 (...)

  • Configuration spécifique pour PHP5

    4 février 2011, par

    PHP5 est obligatoire, vous pouvez l’installer en suivant ce tutoriel spécifique.
    Il est recommandé dans un premier temps de désactiver le safe_mode, cependant, s’il est correctement configuré et que les binaires nécessaires sont accessibles, MediaSPIP devrait fonctionner correctement avec le safe_mode activé.

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Appending a list of movie MP4s causes the sound to be dropped or garbled at some point

    7 février 2020, par Marie

    My process is in 3 steps
    Step 1) Corresponding to each bitmap I have 00.JPG ... NN.JPG I combine a list of "SOURCE" mp3 audio into a single audio mp3 to produce matching 00.MP3 ... NN.MP3

    I had glitch here where one my mp3 was not of the correct Sample Rate, however a kind soul in this forum helped me fix that.
    You can read the details here :

    When I append a silent audio (mp3) to an existing list of audio it garbles the final audio ?

    Step 2) combine each mp3 from previous with a the filename matching bitmap to produce a movie .MP4

    IOW,

    • 00.JPG + 00.MP3 >> 00.MP4
    • 01.JPG + 01.MP3 >> 01.MP4
    • and so on

    From this run of 24 subparts, I hand tested some of these movies against Whatsapp and they are accepted fine.
    However, the final MOVIE.MP4 is not.
    I will list below their info from ffprobe.

    Step 3) combine the list of movies from previous into a final MOVIE.MP4
    This is where I have been having random issues typically with audio, currently this audio drops at about 20s from start. Corresponding to roughly movies parts 04.mp4 to 07.mp4

    I play the videos via VLC but Windows Media Player has even worse playback.

    I am able to reproduce Step3 and thus MOVIE.MP4 with following batch file

    rem 10:33 PM 2/6/2020
    
SET EXE="S:\_BINS\FFmpeg 4.2.1 20200112\bin\ffmpeg.exe"
    

    
SET ROOTPATH=.\
    

    
SET OUT_FILE="%ROOTPATH%MOVIE.MP4"
    

    
SET IN_FILES_LIST="%ROOTPATH%IN_FILES_LIST.TXT"
    

    
SET OPTIONS= -f concat -safe 0 -i  %IN_FILES_LIST%  -c copy -y  %OUT_FILE%
    

    
SET INFO_FILE="INFO.TXT"
    

    
%EXE% %OPTIONS%  1> %INFO_FILE% 2>&1 
    

    
rem PAUSE

    The content of IN_FILES_LIST.TXT

    file '00.mp4'
    
file '01.mp4'
    
file '02.mp4'
    
...
    
file '23.mp4'
    
file '24.mp4'

    (Step 2) uses the following :)

    I have not been able yet to reproduce the issue with a smaller set of movies, in the meantime if you would to get a copy I would have to upload an archive to a link so you can have them on your side.

    Alternatively, if you would like me to provide additional info from these steps let me know what commands and I will be happy to provide.

    Thank you.

    avformat/matroskadec : force full frame parsing of MLP/TrueHD streams

    There's at least one known file with a TrueHD stream that hasn't
    
been correctly muxed, and requires full frame parsing and repack.

    avcodec/mlp_parser : don't try to combine frames when full frames are provided

    Attempting full frame reconstruction is unnecessary for non raw
    
containers, so just skip it altogether.
