更新:
这是对问题的更合适解决方案的更新。下面还提供了原始帖子以供参考。
这篇文章中的脚本,经过一些错误更正后,使用 PHP 工作并提取流标题:
PHP script to extract artist & title from Shoutcast/Icecast stream.
我不得不进行一些更改,因为最后的 echo 语句引发了错误。我在函数之后添加了两个 print_r() 语句,并在调用中添加了 $argv[1],以便您可以从命令行将 URL 传递给它。

使用更新的代码,它会打印标题和流标题信息的数组。如果只想要 now_playing 曲目,则注释掉这两个 print_r() 语句,并取消注释末尾的 echo 语句。
#Example: run this command:
php getstreamtitle.php http://162.244.80.118:3066
#and the result is...

这是使用 python 和 vlc 的原始帖子
PHP 解决方案一直在搜索,但从未为我返回响应。
这不是 PHP 所要求的,但可以帮助其他人寻找从实时流中提取“now_playing”信息的方法。
如果您只想要“now_playing”信息,您可以编辑脚本以返回该信息。
python 脚本使用 VLC 提取元数据(包括“now_playing”轨道)。您需要 VLC 和 python 库:sys、telnetlib、os、time 和 socket。
#!/usr/bin/python
# coding: utf-8
import sys, telnetlib, os, time, socket
HOST = "localhost"
password = "admin"
port = "4212"
def check_port():
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
res = sock.connect_ex((HOST, int(port)))
sock.close()
return res == 0
def checkstat():
if not check_port():
os.popen('vlc --no-audio --intf telnet --telnet-password admin --quiet 2>/dev/null &')
while not check_port():
time.sleep(.1)
def docmd(cmd):
tn = telnetlib.Telnet(HOST, port)
tn.read_until(b"Password: ")
tn.write(password.encode('utf-8') + b"\n")
tn.read_until(b"> ")
tn.write(cmd.encode('utf-8') + b"\n")
ans=tn.read_until(">".encode("utf-8"))[0:-3]
return(ans)
tn.close()
def nowplaying(playing):
npstart=playing.find('now_playing')
mystr=playing[npstart:]
npend=mystr.find('\n')
return mystr[:npend]
def metadata(playing):
fstr='+----'
mstart=playing.find(fstr)
mend=playing.find(fstr,mstart+len(fstr))
return playing[mstart:mend+len(fstr)]
checkstat()
docmd('add '+sys.argv[1])
playing=""
count=0
while not 'now_playing:' in playing:
time.sleep(.5)
playing=docmd('info')
count+=1
if count>9:
break
if playing == "":
print("--Timeout--")
else:
print(metadata(playing))
docmd('shutdown')
例如,从 Crypt Theatre Station 提取元数据:
./radiometatdata.py http://107.181.227.250:8026
