  • 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" (...)

  • Possibilité de déploiement en ferme

    12 avril 2011, par

    MediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
    Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

  • How to reduce the frame-rate programmatically with FFMPEG

    11 avril 2013, par stackr

    I'm looking for a way, or the best way, to get a high-frame-rate movie in a stream (http or rtsp) to run smooth on my (in my case) iPhone app. The normal frame-rate movies run smooth (approx. 30fps), but want special high frame rate movies to also run smooth.

    The way i was thinking was dropping frames when there is not enough time to process the frames.
    Or is there perhaps another way ?

    Can anybody point me in the right direction of fixing this, or perhaps supply me some samples ?

    I use FFMPEG, so there must be some experts here.

  • MP4 Videos on website embed with html5 does not play on iOS

    31 août 2012, par Sidner

    So I have a couple of videos on my website that I shot using the iPhone 4 and then converted to mp4, webm and ogg, so that I can use them with html5. Thing is, the video does not play at all on the 4 iOS devices that I tested and neither on Chrome for Android.

    The Chrome issue could be because some of the mp4 are actually m4v files, but still after encoding with handbrake a video to the iphone 4 presset and in mp4 format, it still does not play.

    What happens, you ask ? Well, it shows the play button crossed out with a diagonal bar, the debug console on Safari does not show any message untill I try to access the video directly. Then it says : QuickTime Movie could not be played.

    What can I do ? I have been trying to encode with ffmpeg, have tried a handful of different solutions, some even found here on stackoverlow, but to no avail. The videos do get shorter, both in display size and MBs, but nothing works to fix the issue at hand.

    I've been trying to get this corrected for a couple of weeks now. Any help and/or suggestions are welcome.

    Thank you.

    By the way, all the videos are on a registred users section of the website, but I have one for debugin on the main page, so feel free to test.
