Python VLC MediaPlayer - Setting Volume

Python VLC MediaPlayer - Setting Volume

The VLC MediaPlayer from the python-vlc module can be used to play audio and video in Python applications. If you want to set the volume for a vlc.MediaPlayer instance, you can use the audio_set_volume method, which takes an integer value from 0 to 100, where 0 is mute and 100 is the maximum volume.

Here's an example of how to use the vlc.MediaPlayer to play a media file and set its volume:

import vlc import time # Create a VLC instance vlc_instance = vlc.Instance() # Create a MediaPlayer with the VLC instance player = vlc_instance.media_player_new() # Load the media file media = vlc_instance.media_new('path_to_your_media_file.mp3') # Replace with your file path player.set_media(media) # Play the media file player.play() # Set the volume player.audio_set_volume(50) # Set to 50% of the maximum volume # Let it play for 10 seconds time.sleep(10) # Stop playing player.stop()

In this example:

  • A new VLC instance is created.
  • A new MediaPlayer object is instantiated with that VLC instance.
  • The media to be played is loaded using media_new with the file path as an argument.
  • The media is set to play with player.play().
  • The volume is set to 50% of the maximum using player.audio_set_volume(50).
  • We use time.sleep(10) to let the media play for 10 seconds before stopping it.

Make sure you have the python-vlc module installed, and that the VLC media player is correctly installed on your system for the Python bindings to work. You can install python-vlc using pip if you haven't done so:

pip install python-vlc

Please replace 'path_to_your_media_file.mp3' with the actual path to the media file you want to play. The file can be an audio file like MP3 or WAV, or a video file if you're using this within a GUI application that provides a drawable area for the video.
