• avformat/scd : add demuxer

  1er décembre 2021, par Zane van Iperen

  avformat/scd : add demuxer
  Adds demuxer for Square Enux SCD files.
  Based off [1] and personal investigation.
  This has only been tested against Drakengard 3 (PS3) *_SCD.XXX files
  
  (big-endian). As it is highly likely that FFXIV (PC) files are little-endian,
  
  this demuxer is marked as experimental until this can be confirmed.

• 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

  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)


  


• Why is my Youtube Video not downloading completely ? "Input buffer exhausted, packet corrupt"

  15 septembre 2021, par user16909319

  Introduction :

  


  I'm working on a Discord Music Bot for personal use only. Basically, when I play a 2min song with the bot, it plays the song for 1min 30secs, then skips it and plays the next one in the queue. The error is shown below :

  


  


  Error in Pull Function
  
IO error : Error number -10054 occurred
  
[mov,mp4,m4a,3gp,3g2,mj2 @ 0000018f86a6f4c0] Packet corrupt (stream = 0, dts = 11154432).
  
Input buffer exhausted before END element found
  
Invalid Data found when processing Input
  
[mov,mp4,m4a,3gp,3g2,mj2 @ 0000018f86a6f4c0] stream 0, offset 0x3e805c : partial file

  


  


  The code block which I think is causing the problem :

  


  Search song method

  


      async def search_song(self, amount, song, get_url=False):
        info = await self.bot.loop.run_in_executor(None, lambda: youtube_dl.YoutubeDL(ytdl_format_options).extract_info(
            f"ytsearch{amount}:{song}", download=False, ie_key="YoutubeSearch"))
        if len(info["entries"]) == 0: return None

        return [entry["webpage_url"] for entry in info["entries"]] if get_url else info


  


  Play_song method

  


      async def play_song(self, ctx, song):
        url = pafy.new(song).getbestaudio().url
        ctx.voice_client.play(discord.PCMVolumeTransformer(discord.FFmpegPCMAudio(url, executable="C:/ffmpeg/bin/ffmpeg.exe")),
                              after=lambda error: self.bot.loop.create_task(self.check_queue(ctx)))
        ctx.voice_client.source.volume = 0.5


  


  Formatting Options I provided :

  


  ytdl_format_options = {
    'format': 'bestaudio/best',
    'outtmpl': '%(extractor)s-%(id)s-%(title)s.%(ext)s',
    'restrictfilenames': True,
    'noplaylist': True,
    'nocheckcertificate': True,
    'ignoreerrors': True,
    'logtostderr': False,
    'quiet': True,
    'no_warnings': True,
    'default_search': 'auto',
    'source_address': '0.0.0.0'
}


  


  Solutions that I've tried :

  


  

  • Running it on both Replit and locally.

  


  • Redownloading FFmpeg

  


  • Ensuring FFmpeg, pafy, and youtube_dl are all up to date.

  


  


  Things to Note :

  


  

  • Playing a 2mins song, it stops after 1min 30 seconds and displays the error above. (75% of the song)

  


  • Playing a 1hr song, it still continues after 10 minutes.

  


  


  I do not have much experience in this yet so I'm not entirely sure where in my code is actually causing this issue or other ways which I can use to test and fix the issue.
