Python VLC MediaPlayer - 获取所选视频的高度

在本文中，我们将了解如何在Python vlc 模块中获取 MediaPlayer 对象的高度。 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。 MediaPlayer 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高度，如果没有指定索引，则返回正在进行的视频高度。

In order to do this we will use video_get_height method with the MediaPlayer object
Syntax : media_player.video_get_height(n)
Argument : It takes integer as optional 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 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 height at index 0
value = media_player.video_get_height(0)
 
# printing height
print("Height at Index 0 : ")
print(value)

输出 ：

Height at Index 0 : 
720

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 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 height at index 0
value = media_player.video_get_height(0)
 
# printing height
print("Height at Index 0 : ")
print(value)

输出 ：

Height at Index 0 : 
480
