• FFMPEG image + music = video

  24 septembre 2017, par Nikita Slastikhin

  Just trying todo video for youtube from image (1080p .png) + music (320Kb mp3).

      ffmpeg -loop 1 -i image.png -i music.mp3 -c:a copy -c:v libx264 -crf 0 -preset veryslow -shortest output.mp4
  

  But converting is to slowly.
  Any ideas, how it make optimize ?

  E:_TEST>ffmpeg -loop 1 -i image0.png -i music0.mp3 -c:a aac -c:v libx264 -crf 0 -preset veryfast -shortest video0.mp4

• Discord.py Music Bot problem with FFmpeg on heroku

  16 mai 2020, par Phantom_7331

  I'm coding my first music bot for discord and successfully tested it on the localhost. After that, I moved it on Heroku and installed FFmpeg buildpack for it. But for some reason, it doesn't work.
Here is proof that I installed FFmpeg buildpack on Heroku : Screen

  



  Here is my code (that works well on localhost) :
