stream - Liquidsoap 不会重新加载播放列表文件

Question

我在使用 Liquidsoap 时遇到了一个非常奇怪的问题。我有以下播放列表:

myplaylist = playlist(mode="normal",playlist_file,reload_mode="rounds",reload=1)

myplaylist = on_metadata(apply_metadata,myplaylist)

其中 apply_metadata 调用一个 python 脚本，该脚本在调用时立即更新播放列表，但有时 Liquidsoap 在重新加载后仍继续播放旧播放列表，即使调用了 apply_metadata 过程也是如此。

预先感谢您的帮助。

Liquidsoap脚本的完整代码:

# This function is called when
# a new metadata block is passed in
# the stream.
def apply_metadata(m) =
  title = m["filename"]
  artist = m["artist"]
  print("Now playing: #{title} by #{artist}")

  filename = string.split(separator="/",title) # rozdelime cestu po lomitkach
  filename = list.nth(list.rev(filename),0) # vezmeme meno suboru
  filename = list.nth(string.split(separator="\.",filename),0) # odpojime koncovku .mp3

  command = "python3.3 feedback.py " ^ filename
  system(command)

end

#!/usr/bin/liquidsoap 
# Log dir 
set("log.file.path","/tmp/basic-radio.log")

#tidy up before playing playlist
playlist_file = "playlist.m3u"
system("python3.3 feedback.py -init")


# Music 
myplaylist = playlist(mode="normal",playlist_file,reload_mode="rounds",reload=1)

myplaylist = on_metadata(apply_metadata,myplaylist)

# Stream it out 
output.icecast(%mp3, host = "localhost", port = 8080, password = "baldur", mount = "stream", myplaylist, fallible=true)

我终于找到了the solution asking in the Liquidsoap's mailing list :

The first though that comes to my mind is that you are perhaps using playlist() in a way this is not intended to be..

Have you though about using request.dynamic? This operator gives you full control over which song is being played next and the next track callback can be written in any language of your choice, which also makes is more convenient..

Good luck!
