Python VLC MediaPlayer – 获取所选视频的宽度

在本文中，我们将了解如何在Python vlc 模块中获取 MediaPlayer 对象的宽度。 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。我们可以通过传递视频的索引来获取所选视频的宽度，如果没有指定索引，则返回正在进行的视频宽度。

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

Syntax : media_player.video_get_width(n)

Argument : It takes integer as optional argument

Return : It returns integer

编程需要懂一点英语

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 resource locator
mrl = "death_note.mkv"
  
# setting mrl to the media player
media_player.set_mrl(mrl)
  
# 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 width at index 0
value = media_player.video_get_width(0)
  
# printing width
print("Width at Index 0 : ")
print(value)

输出：

Width at Index 0 : 
1280

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 resource locator
mrl = "1.mp4"
  
# setting mrl to the media player
media_player.set_mrl(mrl)
  
# 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 width at index 0
value = media_player.video_get_width(0)
  
# printing width
print("Width at Index 0 : ")
print(value)

输出：

Width at Index 0 : 
854
