  • 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.
    Le super Cron (gestion_mutu_super_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 (...)

  • Anomalie #4775 (Fermé) : warning en php 8 avant l’installation

    7 mai 2021, par Franck D

    Hello :)

    Firefox 88.0.1
    SPIP 4.0.0-alpha GIT [master : 42d36eda]

    Laragon avec :
    php 8.0.3
    Apache 2.4.46
    MySQL 8.0.23
    phpMyAdmin 5.1.0

    Juste pour dire que, si je vais sur l’url avant que spip soit installer, j’ai 3 warnings (qui sont aussi visible une fois l’installation faite) dans tous les cas, il suffit d’actualiser la page pour qu’elles disparaissent (voir copie d’écran)

  • Avoiding ffmpeg audio drift for live dash output

    22 mai 2021, par mdale

    Have people experienced playback drift with ffmpeg based dash segment generation ? For example :

    &#xA;

    ffmpeg -threads 2 -re -fflags &#x2B;genpts -stream_loop -1 -i AVSyncTest.mp4 \&#xA;-af "aresample=async=1:min_hard_comp=0.100000:first_pts=0" \&#xA;-c:v:0 libx264 \&#xA;-pix_fmt:0 yuv420p \&#xA;-preset:0 medium \&#xA;-a53cc:0 1 \&#xA;-nal-hrd:0 cbr \&#xA;-x264opts:0 scenecut=-1:rc_lookahead=0 -b:v:0 5000k -bufsize:0 500k \&#xA;-force_key_frames:0 "expr:gte(t,n_forced*2)" \&#xA;-bf:0 8 \&#xA;-r 30 \&#xA;-c:a:0 aac  -ar 48000 \&#xA;-b:a:1 96k  \&#xA;-f tee -map 0:v \&#xA;-map 0:a "[f=dash:media_seg_name=&#x27;chunk-stream_\$RepresentationID\$-\$Number%05d\$.mp4&#x27;:init_seg_name=&#x27;init-stream_\$RepresentationID\$.mp4&#x27;:seg_duration=2:utc_timing_url=https\\\://time.akamai.com\\?iso:remove_at_exit=0:use_timeline=0:http_user_agent=ffmpeg_encoder.0:streaming=1:index_correction=1:timeout=1:dash_segment_type=mp4:method=PUT:http_persistent=1:adaptation_sets=&#x27;id=0,streams=v\:0 id=1,streams=a&#x27; ]http://localhost:5000/out.mpd "&#xA;

    &#xA;

    After a bit of playback it starts audio starts to drift. Analysis of the moof (with tools like mp4box) shows 1024 sample size with 93 Moofs with Moof->traf->default_sample_duration=1024 at 48000 sample rate giving segment duration of 1.984 seconds with every 3rd segment or so with 92 Moofs with duration of 1.962 … While each segment starts aligned ( if you reset playback you get alignment) it drifts against continuous playback.

    &#xA;

    Other examples like Akamai’s public stream. show 94 Moofs or 2.005 duration with every 3rd segment or so at the 1.984 duration. (what one would want)

    &#xA;

    Akamai’s (presumably ffmepg based) stream is averaging out to the 2s target where the above ffmpeg command is not …
