Récupération d’informations sur le site maître à l’installation d’une instance
26 novembre 2010, parUtilité
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 (...) -

Audio Files downloaded from YouTube-DL are corrupted
1er juin 2022, par SushilI 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 wraientI 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 MonsterMMORPGThis is command i have used to download from periscope by using latest youtube-dl
youtube-dl -v periscopeurlThen 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.mp4I 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
