  • 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.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Upload audio file, convert bitrate, save to S3 | server side options ?

    29 septembre 2011, par Jonathan Coe

    Currently using PHP 5.3.x & Fedora

    Ok. I'll try to keep this simple. I'm working on a tool that allows the upload & storing of audio files on S3 for playback. Essentially, the user uploads a file (currently only allowing mp3 & m4a) to the server, and the file is then pushed to S3 for storage via the PHP SDK for amazon aws.

    The missing link is that I would like to perform a simple bitrate & format conversion of the file prior to uploading the file. (ensuring that all files are 160kbs and .mp3).

    I've looked into ffmpeg, although it seems that the PHP library only allows for reading bitrates and other meta, not for actual conversion.

    Does anyone have any thoughts on the best way to approach this ? Would running a shell_exec() command that performs the conversion be sufficient to do this, or is there a more efficient/better way of doing this ?

    Thanks in advance ! Any help or advice is much appreciated.

  • A way to convert bitrate/format of audio files (between upload & storage to S3)

  • Streaming without Content-Length in response

    29 août 2011, par kain

    I'm using Node.js, Express (and connect), and fluent-ffmpeg.

    We want to stream audio files that are stored on Amazon S3 through http.

    We have all working, except that we would like to add a feature, the on-the-fly conversion of the stream through ffmpeg.

    This is working well, the problem is that some browsers checks in advance before actually getting the file.

    Incoming requests containing the Range header, for which we reply with a 206 with all the info from S3, have a fundamental problem : we need to know in advance the content-length of the file.

    We don't know that since it is going through ffmpeg.

    One solution might be to write out the resulting content-length directly on S3 when storing the file (in a special header), but this means we have to go through the pain of having queues to encode after upload just to know the size for future requests.
    It also means that if we change compressor or preset we have to go through all this over again, so it is not a viable solution.

    We also noticed big differencies in the way Chrome and Safari request the audio tag src, but this may be discussion for another topic.

    Fact is that without a proper content-length header in response everything seems to break or browsers goes in an infinite loop or restart the stream at pleasure.

    Ideas ?
