  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.

  • Determinate song's tempo using ffmpeg

    10 janvier 2019, par alexey polusov

    I found ffmpeg library pretty good for converting from mp3 to wav.
    I’m using this library to convert :

    https://github.com/WritingMinds/ffmpeg-android-java

    Then I want to do this steps :

    • determinate songs tempo
    • convert it into wav
    • slice the song into segments according to bpm :
      for example per bar or per 1/2 note.

    I haven’t found any command that I can determinate bpm.
    Maybe you guys know if ffmpeg can actually do it, or advice another library that can handle this problem

  • Live audio streaming from IP camera/rtsp to website

    16 décembre 2018, par Peter Pihlmann Pedersen

    I have a Dahua IP camera with a microphone. I would like to get the audio stream playing on a website like a live radio.

    I have a raspberry pi which I was planning to use with ffmpeg, but I haven’t had much success in bridging the gap between that and my website to form an audio stream.

    • Can this be done via sftp/ftp with mp3 files and some fancy php/javascript to play like a live radio ?

    • Do I need to use another service ? (would like to minimise costs as much as possible !)

    Thanks !
