  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Seeking to Start Time in Piped FFMPEG Input

    18 septembre 2020, par Trevor Ballard

    I am trying to convert a series of videos into a livestream with FFMPEG. To do this, I have a program which copies video files to stdout and have configured ffmpeg to read from a pipe input.

    


    The only issue is I cannot seek to a particular start time with -ss. I can specify duration with -t, but the output will always begin at the start of the input stream. For example :

    


    cat input.ts | \
ffmpeg -ss 00:01:15 \
    -t 30 \
    -i pipe: \
    -c:v copy \
    -c:a copy \
    output.ts


    


    FFMPEG reports pipe:: could not seek to position XXXX.XX and begins from the start of the stream, but I am wondering if there is some other way to accomplish this without trimming the files before piping.

    


  • Get waveform data from audio file using FFMPEG

    16 septembre 2020, par Lutando

    I am writing an application that needs to get the raw waveform data of an audio file so I can render it in an application (C#/.NET). I am using ffmpeg to offload this task but it looks like ffmpeg can only output the waveform data as a png or as a stream to gnuplot.

    



    I have looked at other libraries to do this (NAudio/CSCore) however they require windows/microsoft media foundation and since this app is going to be deployed to azure as a web app I can not use them.

    



    My strategy was to just read the waveform data from the png itself but this seems hacky and over the top. The ideal output would be a fix sampled series of peaks in an array where each value in the array is the peak value (ranging from 1-100 or something, like this for example).
