• 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)


  


• Why do I get UnknownValueError() speech_recognition.UnknownValueError when trying to run .recognize_google ?

  20 juillet 2022, par John Smith

  Following code is meant to transcribe a long audio file to text. It is to do this piece by piece. trimmed.wav holds a 15-second-long piece of a longer audio file (whose path is stored in fname) :

  


  #!/usr/bin/env python3

from subprocess import run
from sys import exit

italic = '\33[3m'
end = '\33[m'

try:
    from speech_recognition import AudioFile, Recognizer
except:
    run("pip3 install SpeechRecognition", shell=True)
    from speech_recognition import AudioFile, Recognizer

def transcribe_piece(fname, lang, stime):
    extension = fname[-3:]
    etime = stime + 15
    cmd = f"ffmpeg -ss {stime} -to {etime} -i {fname} -c copy trimmed.{extension} >/dev/null 2>&1"
    run(cmd, shell=True)
    cmd = f"ffmpeg -i trimmed.{extension} -f wav trimmed.wav >/dev/null 2>&1"
    run(cmd, shell=True)
    r = Recognizer()    
    af = AudioFile("trimmed.wav")
    with af as source:
        r.adjust_for_ambient_noise(source)
        audio = r.record(source)
        t = r.recognize_google(audio, language=lang)#UnknownValueError() speech_recognition.UnknownValueError
        print(f"{italic}{t}{end}")
        with open("of", "w") as f:
            f.write(f"{t}\n")
    run(f"rm trimmed.{extension}", shell=True) 
    run(f"rm trimmed.wav", shell=True)
    
    

fname = input("File name? Skip the path if the file is in CWD. The usage of ~ is allowed.\n")

lang = input("""Specify one of the following languages:
fr-BE, fr-CA, fr-FR, fr-CH

en-AU, en-CA, en-GH, en-HK, en-IN, en-IE, en-KE, en-NZ, en-PK, en-PH, en-SG, en-ZA, en-TZ, en-GB, en-US

#for stime in range(0, 10000, 15):
#    try:
#        transcribe_piece(fname, lang, stime)
#    except:
#        run("shred -u trimmed.wav" , shell=True) 
        #run("shred -u trimmed.wav >/dev/null 2>&1" , shell=True) 
#        exit(0)
        
for stime in range(0, 10000, 15):#this loop is only for the sake of debugging, use try/except above
    transcribe_piece(fname, lang, stime)



  


  It gives me the following error :

  


  Traceback (most recent call last):&#xA;  File "/home/jim/CS/SoftwareDevelopment/MySoftware/Python/speech-to-text/long-audio-to-text.py", line 61, in <module>&#xA;    transcribe_piece(fname, lang, stime)&#xA;  File "/home/jim/CS/SoftwareDevelopment/MySoftware/Python/speech-to-text/long-audio-to-text.py", line 31, in transcribe_piece&#xA;    t = r.recognize_google(audio, language=lang)&#xA;  File "/home/jim/.local/lib/python3.10/site-packages/speech_recognition/__init__.py", line 858, in recognize_google&#xA;    if not isinstance(actual_result, dict) or len(actual_result.get("alternative", [])) == 0: raise UnknownValueError()&#xA;speech_recognition.UnknownValueError&#xA;&#xA;</module>

  


  The said error refers to line 31, that is t = r.recognize_google(audio, language=lang).
Why do I get this error ? How might I rewrite this code so that such error does not appear ?

  


• PiCamera stream to youtube with ffmpeg and capture image every second

  9 octobre 2020, par MisterGray

  I'm sending a livestream with a Python script on a Raspberry Pi 4 to Youtube with ffmpeg.

  


  Additionally I want to check the stream for movements. Therefore I want to compare two frames with each other. Since this is relatively computationally intensive, I wanted to limit myself to "only" compare single frames every second.

  


  The camera.capture() command, however, seems to take very long, so the stream hangs again and again.

  


  What is the best way to get a raw frame during the stream ?

  


  Is there a better alternative to detect movements while creating a stream with ffmpeg ?

  


  #!/usr/bin/env python3
import subprocess
from picamera.array import PiRGBArray
from picamera import PiCamera
import time
import cv2
import numpy as np

YOUTUBE = 'rtmp://a.rtmp.youtube.com/live2/'

avg = None
stream_pipe = subprocess.Popen(stream_cmd, shell=True, stdin=subprocess.PIPE)
resolution = (1280,720)
with PiCamera(resolution = resolution) as camera:

    rawCapture = PiRGBArray(camera, size = resolution)

    camera.framerate = 25
    camera.vflip = True
    camera.hflip = True
    camera.start_recording(stream_pipe.stdin, format='h264', bitrate = 6000000)
    while True:
        camera.wait_recording(1)

        # this command takes a long time to finish
        frame = camera.capture(stream_pipe.stdin, 'rgb')

        """
        further calculations
        """

        rawCapture.truncate(0)

    camera.stop_recording()
    stream_pipe.stdin.close()
    stream_pipe.wait()
