VLC Connection Fails: "Cseq mismatch" & "only real/helix" about neolink HOT 8 CLOSED

Hey thanks for the report.

Which cameras are you using this with? Currently it's only tested with a handful of models - the B800/D800.

That's not to say it won't work with the others listed in the readme (just added that section) - but it's untested :)

Reolink RLC-420

edit: and RLC-420-5MP (later issue)

from neolink.

So for the RLC-420, they support RTSP out of the box. For the time being, I am not planning on explicitly adding support for them. I would welcome contributions that add support, but since they're already usable with RTSP, it's fairly low priority.

Or, put another way, would Neolink give you any extra capabilities that you can't already do with those cameras?

Have you noticed discrepancies in the protocol used by various models of the Reolink product line? If so, then may I could capture some transmissions between the Reolink Windows client and the cameras using wireshark?

Another thing that came to mind, I saw in the log:

[2020-05-21T17:04:12Z INFO neolink::bc_protocol::connection] Ignoring uninteresting message ID 79
[2020-05-21T17:04:12Z DEBUG neolink::bc_protocol::connection] Contents: Bc { meta: BcMeta { msg_id: 79, client_idx: 0, class: 0, encrypted: true }, body: ModernMsg(ModernMsg { xml: Some(BcXml { encryption: None, login_user: None, login_net: None, device_info: None, preview: None }), binary: None }) }

I wonder if those messages are alarm signals being sent to the monitoring client to start/stop recording?

from neolink.

That's very possible. My camera sends msg 78 and 79 on connect, which Neolink ignores as you see.

Packet captures would be fantastic - if you can provide them it's possible I can add support. No guarantees, and like I said, your cameras also provide native RTSP.

My ignorance, I did not realize that RLC-420 were supported out of the box. I just installed Moonfire Nvr and am exploring it's ability to handle multiple feeds. The port which seems to work is not 9000, but 554. In the Moonfire configuration (ncurses interface) I populate the admin/password fields and then for the rtsp field I use (for a camera with and permanently assigned IP at 192.168.1.49):

 rtsp://192.168.1.49:554/h264Preview_01_main

I at least got something on the port 554 feed, but with the port 9000, I did not. I recall playing around with these over a year ago and concluding that the port 9000 was not working and speculating that maybe they were not following the protocol.

Perhaps the best resolution for this issue is to close it with the conclusion that RLC-420 on port 9000 are currently not supported.
