Python VLC Instance – Enumerate the defined audio output devices

In this article we will see how we can get the enumerate audio output devices from the Instance class in the python vlc module. VLC media player is a free and open-source portable cross-platform media player software and streaming media server developed by the VideoLAN project. Instance act as a main object of the VLC library with the Instance object we can create media player, list player or any other player available in VLC. Instance class the base classed used in VLC to create various objects. These audio devices can be speaker or headphone as well.

In order to do this we will use audio_output_enumerate_devices method with the Instance object

Syntax : instance.audio_output_enumerate_devices()

Argument : It takes no argument

Return : It returns list of dict

Below is the implementation

# importing vlc module
import vlc

# importing time module
import time

# creating Instance class object
player = vlc.Instance()

# creating a new media list
media_list = player.media_list_new()

# creating a media player object
media_player = player.media_list_player_new()

# creating a new media
media = player.media_new("death_note.mkv")

# adding media to media list
media_list.add_media(media)

# setting media list to the mediaplayer
media_player.set_media_list(media_list)


# 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 audio enumerate devices
value = player.audio_output_enumerate_devices()

# printing value
print(value)

Output :

[{'name': b'adummy', 'description': b'Dummy audio output'}, {'name': b'afile', 'description': b'File audio output'}, {'name': b'amem', 'description': b'Audio memory output'}, {'name': b'directsound', 'description': b'DirectX audio output'}, {'name': b'mmdevice', 'description': b'Windows Multimedia Device output'}, {'name': b'waveout', 'description': b'WaveOut audio output'}]

Another example
Below is the implementation

# importing vlc module
import vlc

# importing time module
import time

# creating Instance class object
player = vlc.Instance()

# creating a new media list
media_list = player.media_list_new()

# creating a media player object
media_player = player.media_list_player_new()

# creating a new media
media = player.media_new("1.mp4")

# adding media to media list
media_list.add_media(media)

# setting media list to the mediaplayer
media_player.set_media_list(media_list)


# 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 audio enumerate devices
value = player.audio_output_enumerate_devices()

# printing value
print(value)

Output :

[{'name': b'adummy', 'description': b'Dummy audio output'}, {'name': b'afile', 'description': b'File audio output'}, {'name': b'amem', 'description': b'Audio memory output'}, {'name': b'directsound', 'description': b'DirectX audio output'}, {'name': b'mmdevice', 'description': b'Windows Multimedia Device output'}, {'name': b'waveout', 'description': b'WaveOut audio output'}]
