• Discord music bot doesn't play songs

  9 octobre 2023, par Gam3rsCZ

  I have made myself a discord bot that also plays music(it's only for my server so strings with messages are in Czech, but code is in English).
Bot worked a while ago but now it stopped, and I don't know where the problem is

  


  I'm getting these errors : HTTP error 403 Forbidden Server returned 403 Forbidden (access denied) and
C :\Users\Me\AppData\Local\Programs\Python\Python311\Lib\site-packages\discord\player.py:711 : RuntimeWarning : coroutine 'music_cog.play_next' was never awaited

  I already tried everything I can think of(which isn't a lot because I suck at programming), and also tried searching for some solution on the internet, but nothing worked.

  


• FFMPEG concat 2 files of different resolution hangs

  I am trying to concat 2 videos of different size and resize it to 426x240 :

  In the output I see :

  Process hangs and I see that ffmpeg uses 500% of the CPU. Any idea how to fix (deal with) this ?

  


  I can open both videos on my computer and play them.

  


• FFmpeg does not encode chapter titles [closed]

  15 octobre 2023, par Shironats

  I am trying to add chapters to a .mp4 file.
When I tried extracting the metadata using the following command :

  


  ffmpeg -i INPUT.mp4 -f ffmetadata FFMETADATAFILE.txt

  


  I got an output file as follows :

  


  ;FFMETADATA1
major_brand=mp42
minor_version=0
compatible_brands=isommp42
encoder=Lavf60.15.100


  


  So now I try to add some chapters as such

  


  [CHAPTER]
TIMEBASE=1/1000
START=0
END=424510
title=mytitle1

[CHAPTER]
TIMEBASE=1/1000
START=424511
END=941600
title=mytitle2

[CHAPTER]
TIMEBASE=1/1000
START=941601
END=1227260
title=mytitle3


  


  I use the ffmpeg -i INPUT.mp4 -i FFMETADATAFILE.txt -map_metadata 1 -codec copy OUTPUT.mp4 command to encode the metadata to my video file, and for some reason I only ever get 'Chapter 0', 'Chapter 1', and 'Chapter 2'.

  


  I tried using the -map_chapters 1 argument as well but results have been unchanged.

  


  I am using the Latest Auto-Build (2023-10-14 13:02) Windows build by BtbN. Thanks in advance for the help.
