  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • MediaSPIP en mode privé (Intranet)

    17 septembre 2013, par

    À partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
    Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.
    Ce système peut être particulièrement utile pour certaines utilisations comme : Atelier de travail avec des enfants dont le contenu ne doit pas (...)

  • Sorenson Video 3 For Posterity

    12 août 2010, par Multimedia Mike — Software Museum

    On a recent dumpster dive, I procured a complete, never-been-opened copy of Sorenson Video 3 Professional Edition Compressor for Windows. And because I’m me, I thought it would be interesting to document it here :



    Not opened until now, anyway :



    I chuckled at the thought that I might open the user manual and find the complete data stream format listed therein. As expected, the guide offers a broad overview of video compression concepts (lossy vs. lossless, inter/intraframes, that kind of thing) and goes on to describe general guidelines for compressing different types of data. Then there is the feature reference. There are standard features and professional features (the latter includes things like bidirectional prediction, masking, and watermarking).

    I was hoping to figure out how to encode some video with this software. But I think I need full Quicktime Pro in order to do that. If you’re interested, here’s the user manual in PDF format : Sorenson Video 3 User Guide (626 Kbytes). Here’s an interesting claim from the chapter on audio compression :

    Most movies are made up of two parts, video and audio. Historically, the video portion of a digital movie was so large that the audio was only a minor piece of the puzzle. However, with Sorenson Video’s excellent compression capabilities it is possible to create a file where audio is the largest portion.

    I know it’s possible to do that, but is it really recommended ? I’m sure I have some samples in my vast repository where this is the case but it still doesn’t strike me as optimal for network delivery.

  • Add filters and effects by FFMPEG on a live program

    2 mars 2014, par M.Yazdian

    Add filters and effects by FFMPEG on a live program.
    I need to add some effects such as writing at the bottom of a live program and impose the Images of other live cameras on the main camera image through FFMPEG but when I want to add these effects and filters I have to stop FFMPEG, edit command and run FFMPEG again which is not professional.

    All other broadcasting software such as wirecast , vidblaster and others work very well while the main event is going on LIVE, you can add filters and effects without any stop start, just apply the effect and the viewer can see every think live without any interruption

    can you advice me how can I use FFMPEG and add filters and effects without any stop start, I need to just apply the effects and the viewer should see every think live without any interruption.

    Thanks
