• Trying to choose first audio stream of specific language in ffmpeg using python

  3 avril 2024, par R41D

  I have .mkv files that some of them have more than 1 audio stream in the same language so i need to first map the audio streams with specific language and then use only first of them to output .mp4 file. So it would need two -map audio arguments which doesn't work in ffmpeg.

  


  I found out that i could execute ffmpeg mapping audio with that specific language and then pipe the output to another ffmpeg command that would take the first audio stream from the first ffmpeg command and do the rest of things (scaling, burning-in subtitles, encoding it to different format), but i'm not sure how to pipe that output in python's Popen and if it is even possible in windows.

  


  The solution i found with piping :

• Evolution #4471 (Nouveau) : singulier_ou_pluriel pour l’arabe

  13 avril 2020, par George Kandalaft

  Voici le filtre singulier_ou_pluriel adapté à l’arabe (qui a plusieurs formes de pluriels suivant le nombre d’objets) :

  <span class="CodeRay"><span class="comment">/**
   * Afficher un message "un truc"/("deux trucs" pour l'arabe)/"N trucs" 
   * Les items sont à indiquer comme pour la fonction _T() sous la forme :
   * "module:chaine" 
   *
   * @param int $nb : le nombre
   * @param string $chaine_un : l'item de langue si $nb vaut un (ou $nb > 10 pour l'arabe)
   * @param string $chaine_plusieurs : l'item de lanque si $nb > 1 ($nb est compris entre 3 et 10 pour l'arabe)
   * @param string $var : La variable à remplacer par $nb dans l'item de langue (facultatif, défaut "nb")
   * @param array $vars : Les autres variables nécessaires aux chaines de langues (facultatif)
   * @return string : la chaine de langue finale en utilisant la fonction _T()

• Evolution #4358 : Supprimer l’explication d’inscription qui préjuge de l’utilisation

  5 juillet 2019, par RastaPopoulos ♥

  Et je généralise : un formulaire, c’est un truc fonctionnel, qui sert à faire des actions en base : les formulaires fourni par défaut par SPIP devraient toujours être le plus génériques, car ils peuvent ensuite être appelés de diverses manières (dans l’admin, dans le public, etc), parfois même plusieurs fois dans le même site pour des besoins différents.

  Cela n’empêche en rien de construire des interfaces où il y a des explications humaines. Mais celles-ci doivent être le plus possible à l’extérieur des formulaires noyau génériques. Il peut rester des cas où une explication est impérative à l’intérieur même d’un formulaire, mais c’est quelque chose d’extrêmement rare.

  Là par exemple, ça n’a aucun sens de forcer un sens particulier, vu le nombre d’utilisations possibles d’une inscription.
