Python VLC MediaPlayer – 获取字幕描述

在本文中，我们将看到如何在Python vlc 模块中获取 MediaPlayer 对象的字幕描述。 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。字幕是从电影、电视节目、视频游戏等中对话或评论的抄本或剧本衍生而来的文本，通常显示在屏幕底部，但如果有，也可以在屏幕顶部屏幕底部已经有文字。

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

Syntax : media_player.video_get_spu_description()

Argument : It takes no argument

Return : It returns list

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 subtitle description
subtitle = media_player.video_get_spu_description()
  
# printing subtitle description
print("Subtitle Description")
print(subtitle)

输出 ：

Subtitle Description
[(-1, b'Disable'), (3, b'English (Full) - [English]')]

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 subtitle description
subtitle = media_player.video_get_spu_description()
  
# printing subtitle description
print("Subtitle Description")
print(subtitle)

输出 ：

Subtitle Description
