Python VLC MediaPlayer – 获取视频输出数量

在本文中，我们将看到如何在Python vlc 模块中获取 MediaPlayer 对象的视频输出数量。 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。 MediPlyer 对象是 vlc 模块中用于播放视频的基本对象。我们可以借助MediaPlayer方法创建一个 MediaPlayer 对象。视频输出是普通设备的输出源，只有单个视频输出，但也可以大于 1。

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

Syntax : media_player.has_vout()

Argument : It takes no argument

Return : It returns integer

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)
  
# 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 number of video outputs
value = media_player.has_vout()
  
# printing value
print("Number of Video output(s) : ")
print(value)

输出 ：

Number of Video output(s) : 
1

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)
  
  
# 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 number of video outputs
value = media_player.has_vout()
  
# printing value
print("Number of Video output(s) : ")
print(value)

输出 ：

Number of Video output(s) : 
1
