• Error : Unable to extract uploader id - Youtube, Discord.py

  22 juillet 2024, par nikita goncharov

  I have a very powerful bot in discord (discord.py, PYTHON) and it can play music in voice channels. It gets the music from youtube (youtube_dl). It worked perfectly before but now it doesn't want to work with any video.
I tried updating youtube_dl but it still doesn't work
I searched everywhere but I still can't find a answer that might help me.

  


  This is the Error : Error: Unable to extract uploader id

  


  After and before the error log there is no more information.
Can anyone help ?

  


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

  


  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)


  


• youtube-dl - How do I ensure that the "original" video formats are downloaded ?

  25 juin 2018, par Schytheron

  I am building a C# GUI (Windows only) for youtube-dl where I allow the user to pick the desired video quality and framerate but I am having problems with format selection. youtube-dl sometimes downloads either the wrong video file or the wrong audio file (often it is audio) and after merging them I end up with a .mkv file because according to FFmpeg the files I am trying to merge are incompatible.

  These are the format selection queries I have tried to far :

  bestvideo[height<=?%height%][fps<=?%fps%]+bestaudio/best

  and

  public string[] qualities = { "4320", "2160", "1440", "1080", "720", "480", "360", "240", "144" };
  
  public string[] framerates = { "60", "50", "48", "30", "24" };
  
  private void buildFormat(int qualSkip,int fpsSkip)
  
          {
  
              string[] qualitiesMin = qualities.Skip(qualSkip).ToArray();
  
              string[] frameratesMin = framerates.Skip(fpsSkip).ToArray();
  
              format = "-f ";
  
              foreach (string quality in qualitiesMin)
  
              {
  
                  foreach (string framerate in frameratesMin)
  
                  {
  
                      format += "bestvideo[height=?" + quality + "][fps=?" + framerate + "]+bestaudio/";
  
                  }
  
              }
  
              format += "best";
  
          }

  In the first one I had a problem where on some videos youtube-dl downloaded a video in a lower framerate than what I requested (for example, if I request 1080p60FPS I get 1080p30FPS). I tried to fix this in the second method by searching for the best video for all qualities and framerates that are equal to or lower than the one I picked (for example, if I pick 1080p60FPS it would look for videos from 1080p60->1080p30->720p60->720p30->...->144p30).

  The second method however looks overly convoluted and stupid and another problem still remains. youtube-dl always picks the best audio quality no matter what video quality I choose. I want the audio quality to scale with the video quality (for example, if I pick 144p I want poor audio quality). There has got to be a better way.

  Maybe I am explaining this poorly but I basically want youtube-dl to ALWAYS (consistently) download the exact same video and audio format as the one that is displayed in the youtube video player itself for each picked video quality (see image below). How do I do that ?

  Example 1, Video and audio format codes of video in 4K (the numbers in the red circles are the format codes) :
  

  Example 2, Video and audio format of same video but this time in 720p :
  

  (should also pick a lower framerate video of same quality if that framerate is not available in the YouTube quality selector, for example 1080p30FPS in a 1080p60FPS video)

  Thanks !

• FFmpeg Auto Level, Auto Color etc similar to YouTube's Auto-Fix

  22 juin 2019, par Umer

  I used to use YouTube Auto-Fix which presumably auto fixed levels, color, contrast and added a bit of vibrance (it was almost always a bit high saturated which i kinda liked).

  I am looking for an alternate in ffmpeg. I tried using -vf pp=al but it only lightens the video.

  Any ideas ?

  P.S. I can do this in Premiere/After Effects but am looking for a ffmpeg solution.
