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。

1. SRS的配置如下(Config):

**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
