  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Converting AC3 to AAC with minimal loss [on hold]

    20 juin 2016, par forthrin

    iPad does not seem to support the ac3 audio codec.

    Therefore, I am converting an mkv/h264/ac3 movie into m4v/m264/aac using ffmpeg to view it on the iPad.

    The video part is simply copied as it is ; my question is how I preserve the audio as best possible.

    1. Is there any way to do the audio conversion losslessly ?

    2. If no to question 1, what is the best way to preserve the audio quality ? If the source audio is 192 kb/s and 48000 Hz, should I simply use 192/48000 for the target too ? Or will I preserve the audio better if I increase the the bit rate somewhat ?

    3. Side question : I noticed that a lot of mkv files have rather poor audio to begin with. Will the loss of ac3/aac re-encoding be negligable compared to the initial quality loss from the source material ? And why isn’t high audio quality more of a priority for movie files ? It’s not like file sizes matter much anymore with today’s storage and bandwidth.
