Python VLC MediaPlayer - 获得规模

在本文中，我们将看到如何在Python vlc 模块中为 MediaPlayer 对象设置比例。 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。设置比例意味着比例因子，即它根据比例因子改变媒体播放器的大小。可以借助video_set_scale方法进行设置。

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

Syntax : media_player.video_get_scale(n)

Argument : It takes no argument

Return : It returns float

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)
  
# 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 scale factor
value = media_player.video_get_scale()
  
# print value
print("Scale Factor :")
print(value)

输出 ：

Scale Factor :
0.6

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 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 scale factor
value = media_player.video_get_scale()
  
# print value
print("Scale Factor :")
print(value)

输出 ：

Scale Factor :
0.6000000238418579
