VLC 媒体列表播放器定时音频暂停

Question

在使用 Python 程序的 Raspberry Pi 上，我使用媒体列表播放器播放一组音频文件。但我用来设置它的具体代码是：

player = vlc.Instance('--no-xlib --quiet ') # no-xlib for linux and quiet don't complain
media_player = vlc.MediaListPlayer()  # creating a media player object
media_list = player.media_list_new()  # creating a new media list
media_player.set_media_list(media_list)  # setting media list to the media player
new = player.media_player_new()  # new media player instance
media_player.set_media_player(new)  # setting media player to it
media_events = new.event_manager()  # setting event handler
# setting up events
media_events.event_attach(vlc.EventType.MediaPlayerMediaChanged, vlc_SongStarted)
media_events.event_attach(vlc.EventType.MediaPlayerEndReached, vlc_SongFinished)

在 MediaPlayerEndReached 事件中，我试图在 vlc（不是实际程序）中插入一个暂停 - 我试图避免使用“time.sleep()”。基本上，我试图在曲目之间暂停 vlc 3 秒钟。我试过了：

media_player.audio_set_delay(3000)

结果：

AttributeError: 'MediaListPlayer' object has no attribute 'audio_set_delay'

有道理，所以我尝试进入实际的媒体播放器并尝试：

media_player.get_media_player.audio_set_delay(3000)

结果：

AttributeError: 'function' object has no attribute 'audio_set_delay'

我被难住了。有没有办法在 Python 中对 vlc 进行定时暂停，而无需暂停整个 Python 程序？

Answer 1

尝试在 get_media_player 中的 media_player.get_media_player.audio_set_delay(3000) 中添加一对圆括号，使其变为 media_player.get_media_player().audio_set_delay(3000) ;-) !
