注意:提问前,请先看FAQ(Please read FAQ before file an issue) https://github.com/ossrs/srs/issues/2716

描述(Description)

描述你遇到了什么问题(Please description your issue here) 科达设备做国标平台级联,设备注册正常,推流正常,wireshark抓包正常,srs平台报错decode ps packet error。视频流通过海康平台进行过二次转发,海康平台播放正常。

重现(Replay)

重现Bug的步骤(How to replay bug?)

1.科达平台级联到海康 2.海康平台级联到srs

期望行为(Expect)

描述你期望发生的事情(Please describe your expectation) 希望平台级联后可正常播放
