• Anomalie #3227 (Nouveau) : Bug date de publication

  11 juin 2014, par Eric Camus

  SPIP 3.0.16 standard de base (pas de plugins ajouté).

  Si on change à la main (dans le champ) la date de publication en en donnant une erroné ex : 11/06/0014 (erreur sur le 2 de 2014).
  La date une fois validé affiche l’année 14 au lieu de 2014 mais c’est presque normal, la date affiché sur la page "accueil" est 1-1-1970 !! et l’article est toujours en première position.

  Par contre le paramètre "derniere_modif" et uniquement lui dans la base "spip_meta" change à chaque hit sur le site public. Il me semble que cela dé-valide le cache de façon permanente non ?

• Netflix neutrality

  31 mai 2014, par Mans — Law and liberty

  In the net neutrality debate, a rarely mentioned aspect is the widespread practice amongst ISPs of over-subscribing bandwidth. Before streaming video became readily available and popular, this was viable, even reasonable, since few users managed to actually saturate their links for extended periods of time.

• Problems video playing in some android devices (version 4+) but not in others

  5 juin 2014, par anquegi

  following the settings for video in android developers, http://developer.android.com/guide/appendix/media-formats.html I encoded a video using ffmpeg like this :

  ffmpeg -i gravityTrailer.mp4 -y -f mp4 -vcodec libx264 -profile:v baseline -acodec aac    -strict -2  -profile:a aac_low -b:v 500k -ar 44100 -b:a 128k -ac 2 -r 30 -s 480x360  output_hq.mp4

  which corresponds on sd highquality in table 2 from android developers (link above).

  Then i put this video in a server and use the class android.media.MediaPlayer to reproduce it from that URL like this

  https://cloudapp.somedomain.com/bmftvideos/output_hq.mp4

  The problem is that the video is played on android version 4+

  you can see the video on :
  LG G2,
  Sony xperia S

  you cannot see the video on :
  Samsung galaxy S4,
  BQ (spanish) aquaris 4.5

  And I don not know why

  this is the ffmpeg output :
