  • 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 ;

  • Audio Files downloaded from YouTube-DL are corrupted

    1er juin 2022, par Sushil

    I have written a small piece of code that downloads audios and videos from YouTube using YouTube-DL. Here is my code :

    


    from __future__ import unicode_literals
import youtube_dl

link = input("Enter the video link:")

while True:
    choice = input("Enter a for audio file, v for video file:")
    if choice == "a" or choice == "v":
        break

ydl_opts = {}

if choice == "a":
    ydl_opts = {
        'format': 'bestaudio/best',
        'postprocessors': [{
            'key': 'FFmpegExtractAudio',
            'preferredcodec': 'mp3',
            'preferredquality': '192',
        }],
    }
else:
    ydl_opts = {'format':137}
    
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    info_dict = ydl.extract_info(link, download=False)
    video_title = info_dict.get('title', None)

if choice == "a":
    path = f'D:\\DwnldsYT\\{video_title}.mp3'
if choice == "v":
    path = f'D:\\DwnldsYT\\{video_title}.mp4'

ydl_opts.update({'outtmpl':path})

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ydl.download([link])


    


    This works fine. I am able to play the downloaded audio. But when I try to read the same audio file, it shows me an error.

    


    Code :

    


    from pydub import AudioSegment

song = AudioSegment.from_mp3("D:\\DwnldsYT\\Cartoon - On & On (feat. Daniel Levi) [NCS Release].mp3")


    


    Output :

    Is this because the audio downloaded is corrupted ? And how to solve this problem ? Any help would be appreciated. Thanks !

    


  • How to use python-ffmpeg to stream to platforms like youtube, twtich ? [closed]

    16 mars 2023, par wraient

    I have been using ffmpeg from terminal to stream to twitch for a project. But I have to move it to python I found this python-ffmpeg module but could not find any good documentation. How do I convert this terminal ffmpeg command into python-ffmpeg command ?

    


    "ffmpeg -re -i ./anime/aots8e1.mkv  -c:v libx264 -preset veryfast -b:v 6000k -maxrate 6000k -bufsize 6000k -pix_fmt yuv420p -g 50 -c:a aac -b:a 160k -ac 2 -ar 44100 -f flv rtmp://live-ber.twitch.tv/app/"+streamkey


    


    If there are other better alternative to use ffmpeg and python together, please recommend.

    


  • Converting mp4 file downloaded via youtube-dl from periscope by using ffmpeg gives error

    20 mars 2018, par MonsterMMORPG

    This is command i have used to download from periscope by using latest youtube-dl

    youtube-dl -v periscopeurl

    Then i am running this command to convert it to a proper MP4

    ffmpeg -i gg.mp4 -c:v libx264 -preset veryslow -crf 18 -c:a aac -b:a 192k -pix_fmt yuv420p gg2.mp4

    I am using latest youtube-dl and ffmpeg

    The error i am getting is shown below

    So how can i fix this error ? The file can not be played properly on k lite mega codec player but it can be played on vlc player however can not go to any specific time etc. so it really needs to be properly re-encoded

    C:\temp>ffmpeg -i gg.mp4 -c:v libx264 -preset veryslow -crf 18 -c:a aac -b:a 192k -pix_fmt yuv420p gg2.mp4
