• FFmpeg rtp streaming opus file problems

  22 avril 2017, par Yuriy Aizenberg

  i have the next situation.

  1. Have file on remote VPS server.
  2. I want that this file (opus codec) can be accessible through RTP on my android phone.

  3. I tried ffmpeg with next command :

     ffmpeg -ar 44800 -i bon_jovi_loverboy.opus -acodec libopus -ac 1 -ab 96k -vn -f rtp rtp://127.0.0.1:5004 -loglevel 56

  But got next error :

  bon_jovi_loverboy.opus: Invalid data found when processing input

  Full log :

• Anomalie #3152 (Nouveau) : Écriture raccourcie des propriétés typos avec font

  20 janvier 2014, par b b

  Sur un site je déclare les règles css suivantes sur un élément :

  font-size : 2.62em ; font-family : dosis, sans-serif ;
  

  Si j’active le compresseur, elles sont condensée dans une déclaration font comme ceci :

  font : 2.62em dosis, sans-serif ;
  

  Cette écriture ne donne pas le même rendu car j’ai une règle plus haut dans la feuille de style qui colle l’élément en question en bold. L’utilisation de la déclaration font annule la règle en question car :

  Les propriétés pour lesquelles aucune valeur n’est spécifiée sont définies à leur valeur initiale, qui est normal pour toutes les propriétés pouvant être omises : (font-style, font-variant, font-weight et line-height).

  https://developer.mozilla.org/fr/docs/CSS/font

  Je précise que la css en question contient au moins un @media et un @font-face car Cedric me signale ceci :

  Si ta css est simple, c’est une compression simple qui est a l’oeuvre sans regroupement des regles en une seule. Mais si ta css contient des @media ou @fontface alors la compression passe par CSSTidy.
