• ffmpeg incorrect duration when converting video to HLS

  12 octobre 2016, par Julie Bsd

  I’m facing an issue using ffmpeg to convert video, precisely mp4 video => Http Live Streaming (HLS)

  Once converted to HLS, the .m3u8 file has a wrong duration (e.g : 20,1s instead of 20.00s), causing bugs when playing it with AVPlayer on iOS.
  Playing the video with Safari cause the same issue.

  Example :
  1) Open Safari
  2) Play this video that i’ve converted
  3) Look at the download progression, stopped at 98% cause of wrong duration.
  
  4) When you slide between 98% and 100%, the video player can crash.

  EDIT 1 :

  I’ve edited the command line

   ffmpeg -i  video.mp4 \
  
   -codec copy \
  
   -acodec copy \
  
   -map 0 -f ssegment -g 60 -sc_threshold 0 \

• Chrome, ffmpeg, and ogg

  13 novembre 2016, par porton

  We need to convert mp4 into ogg by ffmpeg (or maybe some other converter) in such a way that the ogg file to be compatible with Chrome browser.

  The command like

  ffmpeg -i x.mp4 x.ogg

  produces an ogg file which does not work in Chrome.

  ffmpeg -i video_mp4_01_vlublennaya_mama.mp4 x.ogg 2>&1 | tee log.txt

  produces

• Anomalie #3535 : liste des rédacteurs connectés

  13 octobre 2016, par guytarr °

  Pierre KUHN a écrit :

  Frank, c’est aussi le cas en 3.0.29 ou la valeur par défaut est vide.

  Je viens de tomber sur ce cas lors d’une montée de version 2.1 à 3.0.
  En 2.1, avec imessage vide, on apparaît dans la liste des connectés. Du coup, pour conserver le comportement sans rien touché, que pensez-vous de peupler à "oui" lorsque la valeur n’est pas "non" pour les 1comite et 0minirezo, afin de suivre la même logique ? c’est ce que j’ai fait pour ma part.
  en 3.0 et 3.1 la résultat de la boucle
  

  (#VAL’Y-m-d H:i:s’|date(#VAL’-15 minutes’) !par en_lignepagination 10’, ’>(#ID_AUTEUR">#NOM[&nbsp ;...
   (#GRAND_TOTAL|>10|oui)
   ([(#GRAND_TOTAL|objet_afficher_nbauteur)])
  ]
  

  donne :<br /><pre>
  
  SELECT auteurs.en_ligne, auteurs.id_auteur, auteurs.nom
  
  FROM spip_auteurs AS `auteurs`
  
  WHERE NOT((auteurs.id_auteur = '1'))
  
      AND ((auteurs.statut  IN ('1comite','0minirezo')))
  
      AND NOT((auteurs.imessage = 'non'))
  
      AND (auteurs.en_ligne > '2016-10-12 23:39:09')
  
  ORDER BY auteurs.en_ligne DESC
  
  </pre>

  Autre solution, corriger la boucle pour obtenir le même comportement qu’en 2.1 que la valeur soit à oui ou vide.
