    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 (...)

  • FFmpeg from Python has Corrupted Output

    14 juillet 2019, par Mazyod

    In a python script, I have :

    os.system(ff_cmd)
    # also tried Popen(ff_cmd, shell=True).wait()

    Then, I ran that same ff_cmd from terminal directly. Here are the results :

    # ff_cmd
    ffmpeg -i "114006.mp3" -acodec pcm_s16le -ar 16000 -ac 1 "114-006-a4dec52a.wav"

    # after running from python
    % file 114-006-a4dec52a.wav
    114-006-a4dec52a.wav: Audio file with ID3 version 2.4.0, contains:MPEG ADTS, layer III, v2,  40 kbps, 16 kHz, Monaural

    # after running from terminal
    % file 114-006-a4dec52a.wav
    114-006-a4dec52a.wav: RIFF (little-endian) data, WAVE audio, Microsoft PCM, 16 bit, mono 16000 Hz

    Can anyone please explain why in the world would they result in different outputs ?

  • How to solve issue with ffmpeg being stuck at 'Opening an input file'

    20 mai 2021, par zv989

    I am using a capture card to capture HDMI audio from another machine.

    



    On my host, output of arecord -l is as follow :

    



    **** List of CAPTURE Hardware Devices ****

    The command that I use is :

    



    sudo ffmpeg -f alsa -i hw:CARD=capture,DEV=0 -t 30 test.wav -loglevel debug


    



    When I ran the command, the log seems to freeze at 'Opening an input file' as below :
