  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • How to make a MPEG-DASH MPD which starts the playback in the middle of the first segment ?

    18 septembre 2018, par ravin.wang

    Here are the reproduce steps :

    1. Normalize an H.264 video stream

      ffmpeg -i 2.h264 -c:v libx264 -intra -r 25 -vf scale=640x360,setdar=16:9 2@25fps@intra@640x360.h264

      (*) After that, I got an H.264 stream where all pictures are H.264 IDR frames, and fps is 25, resolution is 640x360, aspect-ratio is 16:9.

    2. Generate an MP4 file

      MP4Box -add 2@25fps@intra@640x360.h264:timescale=1000 -fps 25 2@25fps@intra@640x360.mp4

    3. Make dash MP4 fragmented content, including init mp4, .m4s files and one .mpd file

      MP4Box -dash 5000 -frag 5000 -dash-scale 1000 -frag-rap -segment-name ’seg_second$Number$’ -segment-timeline -profile live 2@25fps@intra@640x360.mp4

    4. Copy and publish all these files to a folder under one HTTPD server
    5. I want to play from 4s of the first segment, and don’t display any frames before 4s, so I changed the .MPD file to modify the fields "SegmentTemplate@presentationTimeOffset", "SegmentTimeline:S@d/t", like as :

      <?xml version="1.0"?>
      <mpd xmlns="urn:mpeg:dash:schema:mpd:2011" minbuffertime="PT1.500S" type="static" mediapresentationduration="PT0H0M26.000S" maxsegmentduration="PT0H0M5.000S" profiles="urn:mpeg:dash:profile:isoff-live:2011">
      <period duration="PT0H0M26.000S">
      <adaptationset segmentalignment="true" maxwidth="640" maxheight="360" maxframerate="25" par="16:9" lang="und">
       <segmenttemplate presentationtimeoffset="4000" media="seg_second$Number$.m4s" timescale="1000" startnumber="1" initialization="seg_secondinit.mp4">
         <segmenttimeline>
             <s d="1000" t="4000"></s>
             <s d="5000" r="4"></s>
         </segmenttimeline>
        </segmenttemplate>
      <representation mimetype="video/mp4" codecs="avc3.64101E" width="640" height="360" framerate="25" sar="1:1" startwithsap="1" bandwidth="2261831">
      </representation>
      </adaptationset>
      </period>
      </mpd>


    6. Play the MPD url from VLC player, or Edge browser, it always starts the the first frame of the first segment, the frames between 0s 4s are also displayed unexpectedly.

    What’s wrong with my steps ? Or any other options for it ?

  • Evolution #4391 : Squelettes de la dist : améliorer le markup et passer à BEM

    14 octobre 2019, par nicod _

    J’ai parlé trop vite, ça c’est le schéma classique, mais il y a des schémas alternatifs possibles : https://en.bem.info/methodology/naming-convention/#alternative-naming-schemes

    Oui, on peut adapter BEM à ses propres habitudes, mais autant adopter le schéma "officiel", ce sera plus simple pour tout le monde.
