GB28181: The SRS deployment is in the cloud. After completing the configuration of the Hikvision camera for GB28181, it shows online. However, when querying all sessions, the devices are empty.

Encountered the same problem. Using the srs branch feature/gb28181. Tested with 2 camera models, both from Dahua and Hikvision. DS-2DC4420IW works fine, but DS-2DC4223IW registers successfully but the devices are empty. Thought it was a 4G transmission issue, so added the server IP to the camera's whitelist, but still unable to use it even when using an Ethernet cable.

1. The camera can work under a local area network.
2. This phenomenon occurs with cloud cameras.
3. It is also possible to use a camera from another location with GB28181 protocol on the cloud. Preliminary investigation suggests that the cloud port is correctly open and the camera protocol header is correct. The issue may be caused by the internal network preventing the camera's packets from penetrating to the external network.

I also encountered the same problem. My SRS is deployed in the local area network. The national standard devices can register, but when querying the session, there are sessions but no devices, and the channel cannot be seen either.

Record the subsequent troubleshooting:

1. It is possible that the issue was caused by not enabling the ONVIF protocol in the web management interface of the Hikvision camera under Network > Advanced Configuration > Inherit Protocol. This needs further verification. Surprisingly, after enabling ONVIF, the GB28181 streaming started working normally.
2. After 24 hours of continuous streaming testing, it was found that the camera was still online, but the video stream (streams) in the SRS console showed no flow status. Restarting the Hikvision camera did not resolve the issue. Querying the session showed that devices were empty.

3. The code continuously prints within a condition in the do_cycle() function. srs_trace("gb28181: 222222222222222222222222222222222 "); This log indicates that there might be an issue with a certain condition in the device here.

I also encountered this problem. After registration, the server occasionally does not send Invite to the device.

I initially used a certain model of Hikvision camera, which could be registered but couldn't generate a media channel. However, when I used a camera from another brand, it could be registered and automatically generate a media channel. Therefore, it was determined that the compatibility issue lies with this particular camera model.
