  • 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 (...)

  • Ffmpeg "no directory found" when passing in a path to the mp3 file

    21 février 2020, par Eugene Levinson

    How my code should work :

    Join the voice channel with the user who sent the command

    Download the video using the link

    Save it as random 16 digit number .mp3

    Then pass the path to the FFmpeg player to play

    My code :

    The random 16 digit number

    def get_digits(amount):
    
    st = ""
    
    for i in range(amount):
    
        n = random.randint(0,9)
    
        st = st + str(n)
    

    
    return int(st)

    Downloading the file

    def get_path(url):
    

    
    #checking if the directory exists
    
    os.makedirs('Music', exist_ok=True)
    

    
    title = YouTube(url).streams.get_highest_resolution().title
    
    current_directory = pathlib.Path(__file__).parent.absolute()
    

    
    print(str(current_directory))
    

    
    #name for the music
    
    name = str(get_digits(16))
    

    
    YouTube(url).streams.filter(only_audio=True).order_by("bitrate").desc().first().download("Music",name )
    
    return str(str(current_directory) + "/Music/" + name + ".mp3")

    This gets called on command play

    #function to connect to a voice chat
    
async def join_auth(ctx):
    
    try:
    
        channel = ctx.author.voice.channel
    
        vc = await channel.connect()
    
        return vc
    
    except Exception as e:
    
        logg("Exception occured when joining a voice channel: " + str(e),"error",str(ctx.guild.name), str(ctx.guild.id))

    The error I get :
    C:\Users\Eugene\Desktop\Discord bot/Music/4343941300524002.mp3: No such file or directory
    But the directory C:\Users\Eugene\Desktop\Discord bot\Music exists and it does contain the 4343941300524002.mp3 file. Does anyone know why do I get the error ?

  • "Pixel format 'yuvj420p' is not supported" when converting image to video using CUDA hardware acceleration

    11 février 2020, par laurent

    I’m trying to convert an image to a video using CUDA hardware acceleration but I can’t get it to work.

    The basic command I have is this one :

    ffmpeg -y -hwaccel cuvid -i tests/MediaSamples/portrait_0.jpg -t 10 out.mp4

    And I’m getting this error :

    [AVHWFramesContext @ 0x32d3f00] Pixel format 'yuvj420p' is not supported
    
[mjpeg @ 0x2d18480] Error initializing a CUDA frame pool
    
cuvid hwaccel requested for input stream #0:0, but cannot be initialized.
    
Error while decoding stream #0:0: Invalid argument

    I’ve tried setting the pixel format like so, but that didn’t help :

    ffmpeg -y -hwaccel cuvid -pix_fmt yuv420p -i tests/MediaSamples/portrait_0.jpg -t 10 out.mp4

    I’ve also tried many other flags but can’t get anything to work. Any idea what the issue might be ?
