  • Amélioration de la version de base

    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 (...)

    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 (...)

  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • Looking for a free alternative RTSP server for Node.js [closed]

    2 juin 2020, par Maoration

    I'm looking at running my node.js server as an RTSP streaming server, as well as an http server. the ability to get some ffmpeg video output to stream as rtsp to 'localhost' (which will be the server listening), and for multiple clients to request a stream from the server via the rtsp ://... protocol

    



    The most common online implementation is :
https://www.npmjs.com/package/rtsp-streaming-server

    



    However, this is licensed under GPL-3.0, meaning my product would have to be open-source, or I'll be violating the terms of use. I'm afraid thats not possible..

    



    Other common results when searching for a solution are :

    



    https://www.npmjs.com/package/rtsp-server
which just seems to wrap to lower level rtsp protocol messages.

    



    https://www.npmjs.com/package/node-media-server
which provides solutions to many use cases, but I couldnt figure out how to configure it as an RTSP server, or if this would even be possible.

    



    So, any alternatives ? other suggestions ?

    


  • Mixing audio stream into video stream using ffmpeg while retaining original audio from the video stream as background [duplicate]

    18 mars 2020, par Core7s

    I have a live video stream and a live audio stream. The audio stream has to get mixed into the video stream and the resulting stream is pushed to YouTube. I have this working ffmpeg -i videostream -i audiostream -map 0:1 -map 1:0 -shortest -c:a copy -c:v copy -f flv streamout-youtube;
    However I am losing the original audio in the videostream. I want to have the original audio playing at maybe 20% of the original volume.
    I looked around a lot and found maybe I can modify the above command to use -filter_complex to get ffmpeg -i videostream -i audiostream -filter_complex "volume=0.2" -map 0:1 -map 1:0 -shortest -c:a copy -c:v copy -f flv streamout-youtube;

    However, when I add the -filter_complex option, the stream goes dead meaning it doesn’t get pushed to youtube anymore. I have verified the stream keys are correct. This seems to be a rather simple thing but I can’t put my finger on what’s wrong.

    I am using rtmp module of nginx to receive, mix and push out streams.

  • dnxhddec : Decode and use interlace mb flag

    dnxhddec : Decode and use interlace mb flag

    This bit is 1 in some samples, and seems to coincide with interlaced
    
mbs and CID1260. 2008 specs do not know about it, and maintain qscale
    
is 11 bits. This looks oversized, but may help larger bitdepths.
    

    Currently, it leads to an obviously incorrect qscale value, meaning
    
its syntax is shifted by 1. However, reading 11 bits also leads to
    
obviously incorrect decoding : qscale seems to be 10 bits.
    

    However, as most profiles still have 11bits qscale, the feature is
    
restricted to the CID1260 profile (this flag is dependent on
    
a higher-level flag located in the header).
    

    The encoder writes 12 bits of syntax, last and first bits always 0,
    
which is now somewhat inconsistent with the decoder, but ends up with
    
the same effect (progressive + reserved bit).
