• Extract music metadata (music title, album title, artist name...) using react-player

  6 juin 2022, par Pierogi

  I'm building a simple web app that plays music streams.
  
The constitution of the web app is

  


  audio.m4a -> ffmpeg -> nginx + rtmp module -> frontend browser

  


  In the frontend browser, use react-player.
  
The audio data is published as HLS audio data.

  


  So, I want to extract the metadata(music title, album title, artist name ...) from the data and display it in the browser. However, I could not find the way to that.
  
Anyone who knows this ?

• My discord.py music bot fails with "ffmpeg not found"

  17 avril 2022, par ThatNoClueDude

  I am using repl.it to host my Discord.py music bot
It fails with an error saying "ffmpeg is not found"
I used multiple ways to fix the error

  


  npm install ffmpeg-static in shell is my first way how i tried to fix the problem, but it did not do anything.

  


  Even if i do any way, repl.it will still give the error ffmpeg not found.
Can someone please tell any way to fix this issue ??
