  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.

    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Documented ffmpeg commands not recognized by ffmpeg

    2 avril 2020, par agconti

    I'm trying to use options like, ldash and http_opts, as the dash muxer docs describe but FFmpeg doesn't recognize them. I'm on the latest released version of ffmpeg, v4.2.2. I see the changes in the ffmpeg master branch but not in the v4.2 release branch. Does ffmpeg not recognize them because they haven't been released yet ?

    



    Here's the dash muxer docs for reference : https://ffmpeg.org/ffmpeg-all.html#dash-2

    



    Here's a minimal example command with uncut output :

    webmdashenc : Support for live stream manifests

    This patch adds support for creating DASH manifests for WebM Live
    
Streams. It also updates the documentation and adds a fate test to
    
verify the behavior of the new muxer flag.

  • Streaming WebM files on unsupported browsers (Safari, IE, etc)

    14 juillet 2015, par Swaathi K

    I’d like to stream WebM videos to browsers that don’t support it (like Safari/IE). I have no problem in converting the video to a supportable format (like MP4), but the encoding should be on-demand, that is, the server should stream the MP4 content while it’s being converted from Web (WebM -> MP4). I’ve seen a few solutions like Dash and Stream-M, but all these seem to do it the other way around (MP4 -> WebM). Is there a solution that already exists for my problem ? Or do I need to build my own hack ? And also is this solution the only way to stream WebM content onto Safari/IE ?
