  • Initialisation de MediaSPIP (préconfiguration)

    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
    Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.

  • ffmpeg : -copyts makes -t stop at timestamps, not duration

    30 juillet 2017, par arielCo

    From

    -t duration (input/output)

    When used as an input option (before -i), limit the duration of data read from the input file.

    When used as an output option (before an output url), stop writing the output after its duration reaches duration.

    So this should yield a 1-minute file with timestamps starting at 1:49, right ?

    ffmpeg -y -copyts -ss 1:49 -i ~/Videos/input.mkv -c copy -t 1:00 timing-1m49s.mkv

    Wrong. It outputs a file with no frames :

    -rwxrwx--- 1 root users 805 Jul 30 01:36 timing-1m49s.mkv

    I have to specify -t 1:49 or more, and e.g. -t 1:55 produces a 6-second file that starts at 0:00 and according to the metadata should last 1:55.

    I arrived at this point trying to extract a clip and add subtitles in the same command, but this minimal case looks to me contrary to the documentation.
