  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • Récupération d’informations sur le site maître à l’installation d’une instance

    26 novembre 2010, par

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • need help using ffmpeg to "concat" multiple audio files (webm, mp4) to make one longer MP3 of audio

    28 septembre 2020, par djturbojp7

    I have done some searching (for several hours) and tried to manipulate many examples to work for me, but I still keep coming up empty here.

    


    I am using linux-mint 19, with ffmpeg installed. I have a folder with several audio files. The majority of these are "webm" (with no video) and there are a few "m4a". I am trying to make one long mp3 file from the audio in all of these strung together from start to finish.

    


    Lets say for sake of argument, my directory has the following files :

    


    audio file a.webm
audio file b.webm
audio file c.m4a
audio file d.webm


    


    I found a script that I could write online where someone is creating a file called "mylist.txt" with this bit of code :

    


        # with a bash for loop
for f in ./*.*; do echo "file '$f'" >> mylist.txt; done
# or with printf
printf "file '%s'\n" ./*.* > mylist.txt


    


    this generated a text file with the following type of content :

    


    file './audio file a.webm'
file './audio file b.webm'
file './audio file c.m4a'
file './audio file d.webm'


    


    first, I believe the "./" is causing a problem, because when I look at other examples I don't see this but I am not sure why it is generating this way in my script because I don't see this in web examples online. Second, I have tried to "concate" this with ffmpeg but I'm not sure which is the best option. I found some documentation here :

    


    https://trac.ffmpeg.org/wiki/Concatenate

    


    however this example applies to video specifically

    


    Can anyone lead me in the right direction ?

    


    EDIT******

    


    I tried the solution below, with "mylist.txt" as the input and I am getting an error :

    


        user@machine/TEMP$ ffmpeg -i mylist.txt -filter_complex "[0:a][1:a][2:a][3:a]concat=n=20:a=1:v=0[a]" -map "[a]" output.mp3

  • FFmpeg : building example C codes

    23 février 2021, par J. S.

    I have configured and compiled the FFmpeg library using this link :
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

    



    Now, I am trying to build example C codes provided by FFmpeg from here :
https://github.com/FFmpeg/FFmpeg/tree/master/doc/examples

    



    However, when I run make install-examples or make install (suggested by /example/README), I receive this kind of message :

    



    


    make : *** No rule to make target '/doc/examples/README', needed by
 'install-examples'. Stop.

    


    



    I thought this may be due to the rules not being in the correct MakeFile format (I am not sure why they refers to README). How should I go about in fixing this and compiling the example codes ? I have tried to find solutions about this, but there doesn't seem to be much information online.

    



    Thank you.

    doc/default.css + doc/t2h.init : New styles

    The main motive of this commit is to make the offline copy of the HTML doc as
    
pretty as the online (ffmpeg.org) one. This also introduced new styles for
    
<h2> to <h4>.
