In this article we will see how we can set volume of the MediaPlayer object in the python vlc module. VLC media player is a free and open-source portable cross-platform media player software and streaming media server developed by the VideoLAN project. MediaPlayer object is the basic object in vlc module for playing the video. VLC offer us to change the volume of the media, it can be set in the form of percentage i.e 0 means mute and 100 means maximum sound.

In order to do this we will use audio_set_volume method with the MediaPlayer object 

Syntax : media_player.audio_set_volume(n) 

Argument : It takes integer as argument 

Return : It returns if the volume was set, -1 if it was out of range

Below is the implementation 

Python3




# importing vlc module
import vlc
 
# importing time module
import time
 
 
# creating vlc media player object
media_player = vlc.MediaPlayer()
 
# media object
media = vlc.Media("death_note.mkv")
 
# setting media to the media player
media_player.set_media(media)
 
# setting video scale
media_player.video_set_scale(0.6)
 
 
# setting volume
media_player.audio_set_volume(50)
 
# start playing video
media_player.play()
 
# wait so the video can be played for 5 seconds
# irrespective for length of video
time.sleep(5)

Output : Another example Below is the implementation
