• Unable to convert .mp3 to .m4a using ffmpeg [closed]

  26 décembre 2020, par rahulg

  I am fully aware the legal constraints in using libfaac but this is just for my testing purpose.

  



  I have compiled ffmpeg with faac enabled. So when I tried to convert an .mp3 to a .m4a here is the error that I am getting. Please provide a resolution to this problem. I tried it on two different sources of .mp3, still I am getting the same error.

  MP3 file is at http://db.tt/HtpEBpFU

  



  Also while using Faac independently I get this weird error for any file.

• Evolution #4827 (Nouveau) : [UX] Regrouper les versions d’un même plugin

  21 juin 2021, par cam.lafit -

  Il arrive qu’on ait plusieurs version d’un même plugin. Entre autre une version dans plugins/ puis au moins une autre dans plugins/auto/
  SVP liste alors toutes les versions du plugin comme si cela était des plugins distincts. Ce serait plus pertinent de les regrouper dans un même bloc et d’éviter de proposer des actions déjà réalisées (comme la mise à jour)

  

  On pourrait tout regrouper en un seul bloc plugin et proposer les diverses actions disponibles
