• ffmpeg : Resampling with input channels greater than 2 unsupported ?

  13 septembre 2011, par user739711

  This question is already been asked but because that thread is old I am posting again.

  When a video file has 5.1 audio channels ffmpeg is not able to convert it to another format giving error :

  "Resampling with input channels greater than 2 unsupported"

  I saw some blogs saying I can modify the code and or patch ffmpeg for it.

  Any solution found yet ?

• avformat/matroskaenc : Ignore AttachedFiles for track limit

  27 novembre 2019, par Andreas Rheinhardt

  avformat/matroskaenc : Ignore AttachedFiles for track limit
  Attachments are streams in FFmpeg, but they are not tracks in Matroska.
  
  Yet they were counted when checking a limit for the number of tracks that
  
  the Matroska muxer imposes. This is unnecessary and has been changed.
  Also use unsigned variables for the variables denoting TrackNumbers as
  
  negative TrackNumbers are impossible.
  (The Matroska file format actually has practically no limit on the
  
  number of tracks and this is purely what our muxer supports. But even if
  
  this limit were removed/relaxed in the future, it still makes sense to
  
  use small TrackNumbers as this patch does, because greater numbers need
  
  more bytes to encode.)

• Discord music bot won't join Voice channel

  16 mars 2024, par Skely

  I followed a tutorial for creating a music bot in discord, but it will not join my vc no matter what. Every command works and it gives the correct responses and songs is in the queue. The bot have every permission know to man, but it still won't join. Any way to fix this issue ?
Thanks in advance !!

  


  This is my code and files

async def main():
    async with bot:
        await bot.add_cog(help_cog(bot))
        await bot.add_cog(music_cog(bot))
        await bot.start(os.getenv("TOKEN"))

asyncio.run(main())
