Python VLC MediaPlayer – 获取音量

在本文中，我们将了解如何在Python vlc 模块中获取 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。可以借助 audio_set_volume 方法进行设置。

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

Syntax : media_player.audio_get_volume() 

Argument : It takes no argument 

Return : It returns integer

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)
 
# getting volume
value = media_player.audio_get_volume()
 
# printing value
print("Audio Volume : ")
print(value)

输出 ：

Audio Volume : 
50

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)
 
# getting volume
value = media_player.audio_get_volume()
 
# printing value
print("Audio Volume : ")
print(value)

输出 ：

Audio Volume : 
70
