  • 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" (...)

  • Ffmpeg used to slow down mp3. Some audio players get length wrong [closed]

    14 août 2023, par AlanFRCPath

    I have used ffmpeg to slow down an audio file using :

    


    ffmpeg -i input.mp3 -filter:a "atempo=0.8" -vn output.mp3

    


    It produces a 45'55" output from a 36'44" input as expected.

    


    In linux mplayer shows the output file as 45'55" as does ffprobe but XMMS shows it as double at 91'10". The audioplayer in my car which plays mp3 files on USB keys also misreads it length.

    


    Can anyone provide some insight into what is going on here ?

  • Is it possible to encode an audio stream with the exact length (to millisecond) ?

    27 avril 2019, par v010dya

    I am looking to create an output file with a length exactly 30 seconds in either mp3, aac, or vorbis codecs. I have used avconv (and also tried ffmpeg) with the following command :

    avconv  -i input_file_here -c:a aac -b:a 320k -t 30 out.mp4

    This produces the output, stating that it has encoded exactly 30 seconds, but then :

    $ avprobe out.mp4

# avprobe output

    When i encode in mp3 it correctly displays that it does more than 30 seconds during the encoding. When i try vorbis it does slightly less than 30 seconds.

    Is it possible to achieve the length of 30 seconds to the millisecond using any tool (i prefer either avconv).
