main- and sub-stream streaming prevents use of other clients about neolink HOT 13 CLOSED

Some clarification:

While Neolink is running (both mainstream and substream), I can view the two lower-quality streams on the Reolink Android App ("Fluent" and "Balanced" in the app). However, the app immediately says "live viewing failed" when I try to view the 4K stream.

Also, before substreaming functionality was added to Neolink, I had no trouble loading the 4K stream on other clients. Maybe this indicates a software block of some kind?

I can do some more testing on this today and will post results.

My theory is that there are two hardware encoder units. When something connects, one of them is used for that stream. When it's out of available encoders, you get errors.

If this is true, it's Reolink's fault that the output of the encoder isn't shared to various clients if possible. If you're only streaming either of mainStream or subStream to Neolink, is the official app able to display all possible streams?

So I just tried streaming just one 4k feed from the Reolink client. I then tried to connect Neolink (with both streams running) and I get weird video messages. Could be the camera denying the stream?

from neolink.

Yeah, so you're getting the opposite end of what the client experiences when Neolink is already running. Can you rerun with

set RUST_LOG=neolink=debug

? It will print that "weird video message."

Remember, if you exceed two active streams, the third won't work.

Oooh,

[2020-07-06T17:11:50Z DEBUG neolink::bc_protocol::connection] Ignoring uninteresting message ID 33

that's a new message number.

I'll have to add a line that debug prints any uninteresting messages (or indeed all messages).

from neolink.

Sounds good. I'll run again once you do.

from neolink.

Well, it won't solve the underlying issue. What remains to be seen is if the limit is connections or encoders. I think it's encoders, in which case no amount of changes to Neolink will help - you should just connect your viewers to Neolink, which will correctly share the connection to the camera.

from neolink.

I still can stream the substream in the reolink app though. Even when there are 2 or more connections.

from neolink.

Hm, interesting. I have no immediate idea why that would be the case then.

from neolink.

This is no longer a problem in Neolink v0.3.0.

It must be because Neolink uses one less HD in this update?

from neolink.

Hooray. Yeah, I hosed some things when I merged the substream work (it was requesting a stream named both which is bogus). I'd say it's likely related. Glad it's working.
