Python VLC MediaList - 插入媒体

在本文中，我们将看到如何在Python vlc 模块的 MediaList 对象中插入媒体。 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。 MediaList 对象包含多个媒体，换句话说，它具有可以与 MediaListPlayer 对象一起使用来播放这些多个媒体对象的媒体列表。插入意味着我们可以在给定索引处添加媒体，我们可以借助add_media方法将媒体添加到媒体列表中。

In order to do this we will use insert_media method with the MediaList object

Syntax : media_list.insert_media(media, index)

Argument : It takes Media object and index as argument

Return : It returns 0 on success, -1 if the media list is read-only

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 media list object
media_list = vlc.MediaList()
  
# creating a new media
media = player.media_new("death_note.mkv")
  
# adding media to media list
media_list.add_media(media)
  
# creating a new media
media = player.media_new("1.mp4")
  
# inserting  media to media list at index 0
media_list.insert_media(media, 0)
  
# setting media list to the media player
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)

输出 ：

另一个例子

# 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 media list object
media_list = vlc.MediaList()
  
# creating a new media
media = player.media_new("1.mp4")
  
# adding media to media list
media_list.add_media(media)
  
  
# creating a new media
media = player.media_new("death_note.mkv")
  
# inserting  media to media list at index 0
media_list.insert_media(media, 0)
  
  
# setting media list to the media player
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)

输出 ：
