我正在尝试用mp3代理互联网广播。它在访问mp3文件时工作正常,但不适用于mp3流。
我想我错过了一些非常基本的差异,但找不到提示。
祝你好运, 狼
我的测试代码:
#!/usr/local/bin/python2.5
import urllib;
import SocketServer, BaseHTTPServer
import subprocess
class Proxy:
def __init__(self, port=4500):
self.port = port
self.server = SocketServer.ThreadingTCPServer(('', self.port), self.Manager)
class Manager(BaseHTTPServer.BaseHTTPRequestHandler):
def do_GET(self):
self.send_response(200)
self.send_header("Content-type", "audio/mpeg");
self.end_headers();
process = subprocess.Popen("lame --mp3input -m m --abr 128 -b 64 - -", shell=True, bufsize=64,
stdin=subprocess.PIPE, stdout=subprocess.PIPE, close_fds=True)
(streamin, streamout) = (process.stdin, process.stdout)
# Does not work
url = urllib.urlopen("http://stream.srg-ssr.ch:80%s" % "/drs3/mp3_128.m3u")
# Does work
#url = urllib.urlopen("http://www.openbsd.org:80%s" % "/songs/song46.mp3")
buffer = url.read(4096)
while len(buffer) > 0:
streamin.streamout(buffer);
while 1:
data = select.select([streamout.fileno()], [],[],.1);
if len(data[0]) == 0:
break
mp3 = streamout.read(4096)
self.wfile.write(mp3)
buf = url.read(4096)
答案 0 :(得分:0)
问题是你正在阅读不是mp3流而是M3U playlist file。该文件本身不包含任何mp3数据。
您的文件内容是简单文字:
http://zlz-stream10.streamserver.ch/1/drs3/mp3_128
http://glb-stream12.streamserver.ch/1/drs3/mp3_128
http://zlz-stream13.streamserver.ch/1/drs3/mp3_128
http://zlz-stream11.streamserver.ch/1/drs3/mp3_128
http://glb-stream10.streamserver.ch/1/drs3/mp3_128
http://zlz-stream12.streamserver.ch/1/drs3/mp3_128
http://glb-stream13.streamserver.ch/1/drs3/mp3_128
http://glb-stream11.streamserver.ch/1/drs3/mp3_128
每一行都是流本身的URL。阅读M3U文件,解析它并从这些URL下载流数据。
