• How to debug "Error in pull function & Input buffer exhausted"?

  15 September 2021, by 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.

  


• FFmpeg chokes on filenames inside of quotes w/ whitespaces [duplicate]

  I’m trying to convert all of my FLACs in to MP3s. Each artist has a folder, and each album has a subfolder. I used the find command to compile a clean list of all of the FLACs in to a file called songlist, and tried dumping it in to FFmpeg with

  (for SONG in `cat songlist` ; do ffmpeg -i "$SONG" -f mp3 -ab 256000 "`basename "$SONG" .flac`.mp3" || break; done)

  Any time ffmpeg reaches a file with a space or special character it interprets it directly. I don’t understand why, as I thought the quotes around $SONG would sanitize it enough. Any thoughts on how to accomplish this task more efficiently or how to fix my code are welcomed.

  songlist is just filled with full paths to the files. No quotes around the paths.
