• Youtube Dlp returns with error code of 400 [closed]

  10 mars 2024, par nikita goncharov

  I have a python discord bot that can play music and uses discord.py https://discordpy.readthedocs.io/en/stable/. To play get the music I use yt_dlp or youtube_dl. But when requesting a video it returns with a 400 error code.

  


  This is the error with yt_dlp :

  


  WARNING: [youtube] YouTube said: ERROR - Precondition check failed.

  


  WARNING: [youtube] HTTP Error 400: Bad Request. Retrying (1/3)...

  


  WARNING: [youtube] YouTube said: ERROR - Precondition check failed.

  


  WARNING: [youtube] HTTP Error 400: Bad Request. Retrying (2/3)...

  


  WARNING: [youtube] YouTube said: ERROR - Precondition check failed.

  


  WARNING: [youtube] HTTP Error 400: Bad Request. Retrying (3/3)...

  


  WARNING: [youtube] YouTube said: ERROR - Precondition check failed.

  


  WARNING: [youtube] Unable to download API page: HTTP Error 400: Bad Request (caused by <httperror>)</httperror>

  


  I will leave some of the code that I use for my bot... The youtube setup settings :

  


  import youtube_dl

  


  or

  


  import yt_dlp as youtube_dl

  


  youtube_dl.utils.bug_reports_message = lambda: ''


ytdl_format_options = {
    'format': 'bestaudio/best',
    'outtmpl': '%(extractor)s-%(id)s-%(title)s.%(ext)s',
    'restrictfilenames': True,
    'noplaylist': True,
    'nocheckcertificate': True,
    'ignoreerrors': False,
    'logtostderr': False,
    'quiet': True,
    'no_warnings': True,
    'default_search': 'auto',
    'source_address': '0.0.0.0',  # bind to ipv4 since ipv6 addresses cause issues sometimes
}

ffmpeg_options = {
    'options': '-vn',
}

ytdl = youtube_dl.YoutubeDL(ytdl_format_options)


class YTDLSource(discord.PCMVolumeTransformer):
    def __init__(self, source, *, data, volume=0.5):
        super().__init__(source, volume)

        self.data = data

        self.title = data.get('title')
        self.url = data.get('url')
        self.duration = data.get('duration')
        self.image = data.get("thumbnails")[0]["url"]
    @classmethod
    async def from_url(cls, url, *, loop=None, stream=False):
        loop = loop or asyncio.get_event_loop()
        data = await loop.run_in_executor(None, lambda: ytdl.extract_info(url, download=not stream))
        #print(data)

        if 'entries' in data:
            # take first item from a playlist
            data = data['entries'][0]
        #print(data["thumbnails"][0]["url"])
        #print(data["duration"])
        filename = data['url'] if stream else ytdl.prepare_filename(data)
        return cls(discord.FFmpegPCMAudio(filename, **ffmpeg_options), data=data)


  


  Approximately the command to run the audio (from my bot) :

  


  sessionChanel = message.author.voice.channel await sessionChannel.connect() url = matched.group(1) player = await YTDLSource.from_url(url, loop=client.loop, stream=True) sessionChannel.guild.voice_client.play(player, after=lambda e: print(                                        f'Player error: {e}') if e else None) 


  


  I searched for posts with the same error and they where either old or didn't solve my problem.

  


  I tried importing instead of yt_dlp, I tried importing youtube_dl. But when I make the request it does not answer, no exception and no warning it just does not answer, as if the funcion is empty

  


  I will link my other post that I asked. It might be usefull : Error : Unable to extract uploader id - Youtube, Discord.py

  


• Multiple download trim videos ffmpeg + youtube-dl [duplicate]

  4 décembre 2020, par sl4g

  I'm tryng to make a bash script to download and trim videos from URLs in a .txt file, using ffmpeg and youtube-dl. From the Internet I found this https://askubuntu.com/questions/970629/how-to-download-a-portion-of-a-video-with-youtube-dl-or-something-else and this How can I batch/sequentially download m3u8 files using ffmpeg ? and based on that I made this :

  


  #!/bin/bash

#only download the half of urls

HoldList="/home/user/desktop/dir1/code/bash/web.txt"

index=0
while read line ; do
    ffmpeg -ss 00:50:30 -to 00:51:00 -i "$(youtube-dl -f best --get-url $line)" -c:v copy -c:a copy output-${index}.mp4
    ((index=index+1))
done < "$HoldList"


  


  This code only downloads half of the videos. Download one, ignore the next, then repeat...

  


  How can I make not skip every other URL from the file ?

  


  I'm a newbie in Bash script (and in this site), and English is not my first language.
