• discord.py ffmpeg song plays too quickly at the beginning

  30 mai 2023, par C-Gian

  I built a discord bot using discord.py and ffmpeg, it works but the song in the first 0-5 seconds plays too fast, I think it's buffering so I tried to use asyncio.sleep but didn't work, suggestions to solve the problem ?

  


  play func :

  


  with youtube_dl.YoutubeDL(self.opts) as ydl:
    await asyncio.sleep(0.1)
    ydl.cache.remove()
    await asyncio.sleep(0.1)
    info = ydl.extract_info(url, download=False)
    raw_url_song = info['formats'][0]['url']
    await self.real_play(ctx, raw_url_song)


  


  real_play func :

  


  source = await discord.FFmpegOpusAudio.from_probe(processed_url_song, **self.FFMPEG_OPTIONS)
await asyncio.sleep(0.5)
self.vc.play(source, after=lambda e: asyncio.run_coroutine_threadsafe(self.real_play(ctx, processed_url_song), self.client.loop))


  


  these are the options :

  


  self.FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
self.OPTIONS = {'format': 'bestaudio'}
self.opts = {'extract_flat': True, 'skip_download': True}


  


  the functions are separate because I do something else (such as playlists), I have reported only the essential code to understand the problem, and the cache remove is essential to reduce the occurence of HTTP 404 forbidden error, btw also without cache remove the problem persists

  


• ffmpeg batch script that combines multiple audio clips with one image > mp4

  2 mars 2016, par Jamie

  I found this script in another thread and edited it to make this :

  @echo off
  
  for %%F in (*.jpg) do (
  
     if exist "%%~nF.mp3" ( 
  
        ffmpeg -loop 1 -i "%%~nF.jpg" -i "%%~nF.mp3" -acodec libvo_aacenc -vcodec mpeg4 -shortest "%%~nF.mp4" 
  
     ) 
  
  )

  It combines all mp3 files with all jpeg files that share the same filename into a mp4 video with the static image running.

  But the problem is - if I want to convert more than one mp3 file using the same image (let’s say three mp3s), I have to duplicate the same jpeg image three times !

  For example, if I have three Michael Jackson mp3 files :

  MJ1.mp3
  
  MJ2.mp3
  
  MJ3.mp3

  I would need to create :

  MJ1.jpg
  
  MJ2.jpg
  
  MJ3.jpg

  But really I only need one image for all three mp3s.

  What edits do I need to make to the script combine all mp3s with one jpeg file ? Let’s say I wanted every mp3 file in the folder to convert with default.jpg. How would I do this ?
