Python VLC MediaPlayer – 获取当前音轨

在本文中,我们将了解如何在Python vlc 模块中获取 MediaPlayer 对象的当前音轨。 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。对于单个视频,可以在许多音轨中使用,例如,一部电影可以有英语音轨和印地语音轨。当前音轨是当前在媒体中播放的音轨。

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)
  
  
# setting volume
media_player.audio_set_volume(80)
  
# 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 current audio track
value = media_player.audio_get_track()
  
# printing value
print("Current Audio Track : ")
print(value)

输出 :

Current Audio Track : 
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)
  
  
# setting volume
media_player.audio_set_volume(70)
  
  
# 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 current audio track
value = media_player.audio_get_track()
  
# printing value
print("Current Audio Track : ")
print(value)

输出 :

Current Audio Track : 
-1
