I am using libVLC in my project to support some additional audio and video files.
Thereby, I found that the audible volume differs compared to other media players when using low volume and libVLC.

This is also true for normal VLC Media Player.

Questions:

• Which formula does VLC volume (0 to 100) use?
• How to set the VLC volume such that the output volume on the speakers is like other media players?

Steps to reproduce:

• Play an audio file in Windows Media Player, AIMP, and normal VLC, where each media player is set to 20% volume.
• Listen to the audio output.
  • VLC is much more quiet compared to the others.
