Python VLC MediaPlayer –Setting Audio Delay

  • Last Updated : 19 Aug, 2020

In this article we will see how we can set audio delay to 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. MediPlyer object is the basic object in vlc module for playing the video. An audio channel or audio track is an audio signal communications channel in a storage device or mixing console, used in operations such as multi-track recording and sound reinforcement. Audio delay means that audio will get played after the delay time than normal time.

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

Syntax : media_player.audio_set_delay(n)

Argument : It takes integer i.e milliseconds as argument

Return : It returns 0 on success, -1 on error.



Below is the implementation




# 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 audio delay of 100 milliseconds
media_player.audio_set_delay(100)
  
  
# setting volume
media_player.audio_set_volume(80)
  
# 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




# importing vlc module
import vlc
  
# importing time module
import time
  
# creating vlc media player object
media_player = vlc.MediaPlayer()
  
# media object
media = vlc.Media("1mp4.mkv")
  
# setting media to the media player
media_player.set_media(media)
  
  
# setting volume
media_player.audio_set_volume(70)
  
  
# setting video scale
media_player.video_set_scale(0.6)
  
  
  
# setting audio delay of 100 milliseconds
media_player.audio_set_delay(100)
  
  
# start playing video
media_player.play()
  
# wait so the video can be played for 5 seconds
# irrespective for length of video
time.sleep(5)
