  • 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.

  • Que fait exactement ce script ?

    18 janvier 2011, par

    Ce script est écrit en bash. Il est donc facilement utilisable sur n’importe quel serveur.
    Il n’est compatible qu’avec une liste de distributions précises (voir Liste des distributions compatibles).
    Installation de dépendances de MediaSPIP
    Son rôle principal est d’installer l’ensemble des dépendances logicielles nécessaires coté serveur à savoir :
    Les outils de base pour pouvoir installer le reste des dépendances Les outils de développements : build-essential (via APT depuis les dépôts officiels) ; (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • The Future of the VP8 Bitstream

    18 juin 2010, par noreply@blogger.com (John Luther) — vp8

    Recently we’ve seen software products such as VLC, FFmpeg, Logitech Vid, Flumotion and Tixeo adopting and using WebM and VP8 (the video codec in WebM) in exciting new ways.

    In addition to software developers, many hardware vendors have committed to shipping VP8-accelerated products based on our current bitstream in 2011 . Devices that use hardware acceleration for video are a very small percentage of overall web traffic today, but they are a rapidly growing segment of the market and our project must be mindful of these vendors’ needs. Given the longer lead times for changes in chipsets, hardware companies implementing the codec today need to be confident that it will be stable and supported as VP8 content proliferates.

    Like every codec, WebM is not immune to change ; the difference in our project is that the improvements are publicly visible, and compatibility and implementation issues can be worked through in an open forum.

    So, to maintain codec stability while also allowing for quality and performance improvements in VP8, we have added an experimental branch to the VP8 source tree. The WebM community can use this unstable branch to propose changes to VP8 that will produce the best video codec possible, but without the constraints of a frozen bitstream. At some point in the future, when the experimental branch proves significantly better than the stable branch, we will create a new version of the codec.

    Teams dedicated to improving WebM are actively investigating and evaluating new techniques, and are committed to do so for the long term. We encourage the WebM community to keep contributing as well. To learn more about the experimental branch and get involved, see our repository layout page.

  • HTML5 Media and Accessibility presentation

    23 février 2010, par silvia

    Today, I was invited to give a talk at my old workplace CSIRO about the HTML5 media elements and accessibility. A lot of the things that have gone into Ogg and that are now being worked on in the W3C in different working groups – including the Media Fragments and HTML5 WGs – were also (...)

  • Sony Launches Less Useful Z5U

    18 novembre 2009

    Sony today announced the NXCAM, an AVCHD-based "professional" camera which bears a striking resemblance to the EX1 and Z5U.

    You get 1080p exmor CMOS chips (presumably 1/3" ?) and records AVCHD to the highly popular (sarcasm) Memory Stick media.

    Pricing hasn’t been announced, but presumably it’ll be in the $4000 range like the Z5U. I’ll be curious to see how this shakes out in the market.
