• ytdl python "KeyError : formats"

  7 juillet 2022, par Mondumkreisung

  Im trying to make a discord music bot for personal use, since groovy and rythm got shut down.
It's working okay-ish I guess, but im having a problem with ytdl.
typing "-play" and an url is working just like intended, but i cant type "-play 'song name'".
Typing "-play example" gives me this :

  


  [download] Downloading playlist: example
[youtube:search] query "example": Downloading page 1
[youtube:search] playlist example: Downloading 1 videos
[download] Downloading video 1 of 1
[youtube] CLXt3yh2g0s: Downloading webpage
Ignoring exception in command play:
[download] Finished downloading playlist: example
Traceback (most recent call last):
  File "C:\Users\Dennis\PycharmProjects\groovy's true successor\venv\lib\site-packages\discord\ext\commands\core.py", line 85, in wrapped
    ret = await coro(*args, **kwargs)
  File "C:\Users\Dennis\PycharmProjects\groovy's true successor\voice.py", line 53, in play
    url2 = info['formats'][0]['url']
KeyError: 'formats'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "C:\Users\Dennis\PycharmProjects\groovy's true successor\venv\lib\site-packages\discord\ext\commands\bot.py", line 939, in invoke

    await injected(*ctx.args, **ctx.kwargs)
  File "C:\Users\Dennis\PycharmProjects\groovy's true successor\venv\lib\site-packages\discord\ext\commands\core.py", line 94, in wrapped
    raise CommandInvokeError(exc) from exc
discord.ext.commands.errors.CommandInvokeError: Command raised an exception: KeyError: 'formats'


  


  im fairly new to coding, so im sorry if somethings weird to understand.

  


  okay, so : typing -play with an url works fine, but typing -play with the song name doesnt. its only searching for the first word, downloads the first searchresult and then "crashes".

  


  so "-play Rick Astley - Never Gonna Give You Up" for example only searches for "Rick" and then it says something about KeyError : 'formats'
Here is my code :

  


  @client.command()
async def play(ctx, url):
    channel = ctx.author.voice.channel
    voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
    if voice and voice.is_connected():
        pass
    else:
        await channel.connect()

    ffmpeg_opts = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
    ydl_opts = {'format': "bestaudio/best", 'default_search': 'auto'}
    vc = ctx.voice_client

    with youtube_dl.YoutubeDL(ydl_opts) as ydl:
        info = ydl.extract_info(url, download=False)
        url2 = info['formats'][0]['url']
        source = await discord.FFmpegOpusAudio.from_probe(url2, **ffmpeg_opts)
        vc.play(source)


  


• FFMPEG - 4K HDR - MPEG - BIG FILE convert

  8 mars 2018, par Ian Lodanko

  I would like to ask how through ffmpeg to achieve the smallest file size and yet keep the best quality [LIKE Youtube convert].

  Currently used :

  ffmpeg -i "/home/sampe_4K_HDR.mkv" -map 0:00 -c:v libx264 -preset ultrafast -b:v 66718k -pix_fmt yuv420p10le -x264-params "colorprim=bt2020:transfer=smpte2084:colormatrix=bt2020nc" -crf 18 -c:a libfdk_aac -profile:v baseline -level 3.0 "/home/sampe_4K_HDR.mp4"

  But the size of the video after conversion is very large, I would like to preserve as much as possible the quality of the original video and get the smallest possible video size.

  Could you please advise ? Write some examples of how to get better with smaller sizes ? Thank you in advance and I apologize for my English in advance.
