    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 (...)

  • 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" (...)

  • Announcing Dreamroq

    20 mars 2011, par Multimedia Mike — Sega Dreamcast

    I have pushed the first public version of my new Dreamroq (we open source types are just so creative in our naming schemes) library up to Github :

    https://github.com/multimediamike/dreamroq

    To review, this is a library for playing RoQ video files on the Sega Dreamcast. It has a lot of problems right now, many of which are listed in the README file. It comes with a Dreamcast/KOS sample player. It also comes with a simple Unix testing utility which decodes a file to a series of PNM files. If anyone is interested in debugging RoQ again after all these years that it has been supported in other open source programs, there is still a bug in the video decoder that produces some notable artifacts.

    Also, here are some samples I generated that appear to meet the data rate requirements laid out in this post. These samples are based on this sample media set from Xiph.org.

  • Why is the ffmpeg command have a variable bit rate

    5 juin 2013, par Trace

    I have this command

    ffmpeg -i test.mp3 -ac 1 -ab 64000 -ar 44100 output.mp3

    The requirements are

    mp3 (mpeg-1 layer 3) 
    
Bit rate: 64kbps CBR(constant Bit Rate) 
    
Sampling rate: 44.1 
    
Bit depth: 16bit 
    
Channels: mono

    The sample rate is correct, but file came through with a variable bit rate, not constant bit rate

    Any ideas what im missing here

  • ffmpeg - using crf and setting a mximum bitrate [closed]

    1er mars 2013, par user1963939

    I am trying to transcode a video to h.264/mp4.
    I am using the crf = 20 but according to the requirements I also want to limit the maximum bitrate to 3mbps.

    I was trying to cheat though it by using x264opts like this

    -x264opts crf=20:vbv-bufsize=14000:vbv-maxrate=3000:keyint=40

    is that the right way to do this ?
    Can this be done or I am stuck with using a contant bitrate and no crf ?
