Python VLC MediaPlayer – 获取音频输出设备

在本文中，我们将看到如何在Python vlc 模块中获取 MediaPlayer 对象的输出设备列表。 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。音频输出设备可以内置扬声器或耳机以及外部扬声器。

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

Syntax : media_player.audio_output_device_enum()

Argument : It takes no argument

Return : It returns a None-terminated linked list of potential audio output devices. It must be freed with audio_output_device_list_release()

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 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 track
value = media_player.audio_output_device_enum()
  
# printing value
print("Audio Output Devices: ")
print(value)

输出：

Audio Output Devices:

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 track
value = media_player.audio_output_device_enum()
  
# printing value
print("Audio Output Devices: ")
print(value)

输出：

Audio Output Devices: 
vlc.LP_AudioOutputDevice object at 0x0000021A9E961A86
