Python VLC MediaListPlayer - 播放项目

在本文中，我们将看到如何在Python vlc 模块的 MediaListPlayer 对象中播放给定项目。 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。媒体列表播放器用于连续播放多个媒体，例如播放一个系列，而不是接受单个媒体，它接受媒体列表。它的工作方式与 MediaPlayer 对象几乎相似，但它能够播放媒体列表。我们可以借助play方法播放媒体，但它从索引 0 开始播放媒体，并且可以借助play_item_at_index方法播放给定索引处的项目。

In order to do this we will use play_item method with the MediaListPlayer object

Syntax : media_list_player.play_item(media)

Argument : It takes Media object argument

Return : It returns 0 upon success -1 if the item wasn’t found.

下面是实现

# importing vlc module
import vlc
  
# importing time module
import time
  
# creating a media player object
media_player = vlc.MediaListPlayer()
  
# creating Instance class object
player = vlc.Instance()
  
# creating a new media list object
media_list = player.media_list_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 media player
media_player.set_media_list(media_list)
  
# 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 media player
media_player.set_media_list(media_list)
  
  
# start playing the media
media_player.play_item(media)
  
  
  
# wait so the video can be played for 5 seconds
# irrespective for length of video
time.sleep(5)

输出 ：

另一个例子
下面是实现

# importing vlc module
import vlc
  
# importing time module
import time
  
# creating a media player object
media_player = vlc.MediaListPlayer()
  
# creating Instance class object
player = vlc.Instance()
  
# creating a new media list
media_list = player.media_list_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 media player
media_player.set_media_list(media_list)
  
  
# 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 media player
media_player.set_media_list(media_list)
  
  
# start playing the media
media_player.play_item(media)
  
# wait so the video can be played for 5 seconds
# irrespective for length of video
time.sleep(5)

输出 ：
