  libavcodec/sanm : clear codec47 diff buffers with specific color
  The codec47 header provides colors to use to clear the
  
  2 difference buffers. This fixes artifacts (black hair, faces) in
  
  Curse of Monkey Island "CURSERNG.SAN" video.

• OSError : [Errno 9] Bad file descriptor when downloading using pytube and playing with discord.py

  15 septembre 2022, par Trevor Mathisen

  When using pytube to download a YouTube video and discord.py to play it, I am getting a OSError : [Errno 9] Bad file descriptor error. I've had this working at one point and can't seem to figure out what I changed which broke it.

  I've mounted the /media/ dir during docker -v and can see the file is getting downloaded and when I copy the file to my local machine I can play it in an audio player.

  


  The program can access the SQLite database right next to the files in question just fine.

  


  I've deployed the container locally and to two different VPS's with the same file structure with the same behavior. I'm ripping my hair out.

  


• The Mystery of the No such file or directory exception

  22 avril 2022, par JohnWick

  No idea what's going on here. Set a breakpoint after the for of loop in the following function. temp/concat.txt exists but the following exception is thrown :

  


  


  Uncaught Error Error : ffmpeg exited with code 1 : temp/concat.txt : No
such file or directory

  


  


  Outputting stderr gives a bit more info :

  


  


  [concat @ 000001e2e30124c0] Impossible to open
'temp/concat.txt#voiceover #funny #fall #lol.mp4' index.js:19

  And here is the contents of concat.txt, standard ffmpeg concat demuxer format :
