  • 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.

  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.
    La documentation de l’utilisation du script d’installation (...)

  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Transcoding with the GCP Transcoder API results in a time gap

    3 mars 2021, par banyan

    I've been trying GCP's Transcoder API and having trouble with the time randomly becoming shorter than specified in certain cases.

    


    The specific cases are as follows :

    


      

    1. Specifying startTimeOffset and endTimeOffset (cut off 2 seconds before and after the video)

      2. 


    2. fMP4 is used as container

      3. 


    3. input video is mp4 with screen recording on iPad Pro

      4. 


    


    For example, if I don't specify startTimeOffset and endTimeOffset, the time will not be shortened. Also, there is no problem when MPEG2-TS is specified for container. There may be a problem with the video itself, but I haven't found a clue how to set it up.

    


    I'm not sure whether this is a problem with the Transcoder API or with me.

    The following is a ffprobe of the resulting manifest file, which is 2 seconds shorter than specified. (expected : 00:02:47.00, actual : 00:02:45.00) In this case, it's a 2-second gap, but it can be 10 seconds or 30 seconds, and it varies from video to video.

  • FFMPEG muxed as a private data stream and may not be recognized upon reading

    4 mars 2021, par Jimmy

    I've came across a mkv with a codec of hevc , while trying to either convert it to m3u8 or mp4 I received this following message :

    


    [mpegts @ 0x7f94de014600] Stream 1, codec flac, is muxed as a private data stream and may not be recognized upon reading.

    


    Is there something wrong with my ffmpeg parameters ?

    


    To m3u8 :
#1 :

    


    ffmpeg -i aaa.mkv -s 1920x1080 -codec copy -bsf:v hevc_mp4toannexb -start_number 0 -hls_time 10 -segment_time 10 -hls_list_size 0 -f hls aaa.m3u8


    


    #2 :

    


    ffmpeg -i aaa.mkv -s 1920x1080 -codec copy -c:v libx264 -bsf:v hevc_mp4toannexb -start_number 0 -hls_time 10 -segment_time 10 -hls_list_size 0 -f hls aaa.m3u8


    


    To mp4 :

    


    #1 :

    


    ffmpeg -i aaa.mkv -c copy ccc.mp4


    


    #2 :

  • ffmpeg ignores every framerate option, locking the result to 25 fps

    1er août 2023, par Goury

    ffmpeg version 3.4.8-0ubuntu0.2 Copyright (c) 2000-2020 the FFmpeg developers

    


    No matter what I do, ffmpeg just ignores everything and encodes it as if it's 25fps.
    
-framerate 60 does nothing
    
-t 60 does nothing
    
-r 60 makes it to interpolate frames
    
-r:v 60 does the same
    
-vf "fps=60" does the same
    &#xA;-vframes <actual number="number" of="of" frames="frames"></actual> makes it to end the encoding prematurely

    Everything google shows seems to be outdated, including ffmpegs own documentation
