Python VLC MediaPlayer – 获取媒体角色

在本文中，我们将看到如何在Python vlc 模块中获取 MediaPlayer 对象的角色。 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。 MediPlyer 对象是 vlc 模块中用于播放视频的基本对象。角色可以是可用的角色，也可以是自定义角色。可以借助set_role方法进行设置。

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

Syntax : media_player.get_role()

Argument : It takes no argument

Return : It returns media player role

下面是实现

# 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(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)
  
# getting media player role
value = media_player.get_role()
  
# printing value
print("Media Player Role : ")
print(value)

输出 ：

Media Player Role : 
2

另一个例子
下面是实现

# 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 media player role
value = media_player.get_role()
  
# printing value
print("Media Player Role : ")
print(value)

输出 ：

Media Player Role : 
2
