zlm在setup阶段被服务端断开连接，原因已分析，去掉setup时的mode=play就能正常播放， 按照rfc7826，应该是mode="PLAY"，建议去掉mode=play

rfc2326: [Page 61] mode = <"> *Method <"> | Method Example: Transport: RTP/AVP;multicast;ttl=127;mode="PLAY", RTP/AVP;unicast;client_port=3456-3457;mode="PLAY"

rfc7826: 18.54. Transport [Page 180] mode: The mode parameter indicates the methods to be supported for this session. The currently defined valid value is "PLAY". If not provided, the default is "PLAY". The "RECORD" value was defined in RFC 2326; in this specification, it is unspecified but reserved. RECORD and other values may be specified in the future.
