  • 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" (...)

  • 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.

  • Splitting single 32-channel audio file into 32 mono audio files using ffmpeg

    16 janvier 2015, par user1066157

    I am trying to split a single 32-channel audio file in .caf format to 32 mono audio files in signed 16 bit little endian .wav format using ffmpeg, but I can’t figure out how to accomplish this exactly. I have tried to do :

    ffmpeg -i myAudio.caf -acodec pcm_s16le -map 0:0 channel_01.wav -map 0:1 channel_02.wav ...

    But this returns a "Stream map ’0:1’ matches no streams" error. Surely I am missing something entirely obvious here... Most likely I am confused about how to reference each individual channel in my single, multi-channel audio file. Could someone show me the right way of doing this perhaps ?

  • Convert two channels into a single channel left or right with ffmpeg

    1er juillet 2023, par kutlus

    I have some .wav files and I would like to convert their frequency (fs) and number of channels (nchannels). I am using ffmpeg on a Jupyter Notebook, Python 3.6. I used the following command and it works.

    


    cmd= 'ffmpeg -i %s -ar %d -ac %d %s.wav'%(filepath,fs,nchannel,wavfilename)
os.system(cmd)


    


    However, when converting two channels into a single channel, I just want ffmpeg takes only left (or right) channel instead of an average of two signal. If I use map channel as follows, would that be correct ? This creates wav files but I am not sure if only one channel is taken.

    


    'ffmpeg -i %s -ar %d -map_channel 0.0.0 %s.wav(filepath,fs,wavfilename)'


    


    If not, how can I modify my code above to achieve that ? I also tried ;

    


    'ffmpeg -i %s -af channelsplit=channel_layout=stereo:channels=FL -ar %d %s.wav'%(filepath,fs,wavfilename)'


    


    but this created empty wav files.
