• Pass channel id to ffmpeg

  17 octobre 2016, par snowman

  Is there a way to pass a particular channel id to ffmpeg to control a tuner card ?
  I can run the following and capture my tuner card, but would like to pass a particular channel id.

  ffmpeg -f dshow -show_video_device_dialog true -i video="Hauppauge Cx23100 Video Capture" -r 20 -threads 0 -hls_time 10 -hls_list_size 6 -hls_wrap 10 -start_number 1 TEST.m3u8

• Batch script to convert, youtube-dl webm file to mp3 with ffmpeg

  1er avril 2024, par SneakyShrike

  I'm using youtube-dl to extract the best possible audio quality from youtube videos. However the best quality audio usually turns out to be the webm format, which isn't useful. I would like to write a batch script that converts the webm file to an mp3 with ffmpeg. I've already tried using this guide on reddit to do it, but it doesn't seem to work. It appears to create an empty mp3 file that displays an error when i try to play it and the meta data is also completly blank.

  



  Here is the batch script :

  



  for %%a in ("Downloaded\*.*") do %CD%\ffmpeg\bin\ffmpeg.exe -i "%%a" -vn -ar 44100 -ac 2 -ab 192k -f mp3 "Converted\%%~na.mp3" pause


  



  I'll also give an explanation of how the whole thing should work.

  



  The idea is, is that you use youtube-dl to extract the best possible audio, then put that file into the Downloaded folder (see pic below) and then you run the mp3 script (which uses commands from ffmpeg) to convert the webm file in the Downloaded folder to a mp3 file, and place it in the Converted folder. The mp3 script is the code above. But it doesn't seem to work properly.

  



  I'm not very familiar with batch scripting, nor with ffmpeg so any help would be appreicated.

  



  Here is the picture to complement the explanation part.

  



  

  


• 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)
