Python VLC MediaPlayer – 设置音量

在本文中，我们将看到如何在Python vlc 模块中设置 MediaPlayer 对象的音量。 VLC媒体播放器是VideoLAN项目开发的一款免费开源的便携式跨平台媒体播放软件和流媒体服务器。 MediaPlayer 对象是 vlc 模块中用于播放视频的基本对象。 VLC 提供我们改变媒体的音量，它可以以百分比的形式设置，即 0 表示静音，100 表示最大声音。

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

下面是实现

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)

输出 ： 另一个例子下面是实现

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("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)
 
# start playing video
media_player.play()
 
# wait so the video can be played for 5 seconds
# irrespective for length of video
time.sleep(5)

输出 ：
