外部M3U中的udpxy单播源处理错误

[iseku]

问题描述

如果外部M3U中包含了udpxy格式的单播源url ，例如 http://123.226.199.250:4002/rtp/239.253.254.77:8000
应该被解析为http单播源来创建service，但是现在却被当作本地组播源 rtp://239.253.254.77:8000 来处理了
从web服务传入的url没有问题，例如 http://192.168.0.1:5140/http/123.226.199.250:4002/rtp/239.253.254.77:8000

测试样例和日志

加载外部M3U内容：
#EXTINF:-1 tvg-name="CCTV1" group-title="央视频道", CCTV1
http://123.226.199.250:4002/rtp/239.253.254.77:8000

加载配置时日志显示：

使用URL直接请求:
