No rtsp stream from Reolink Argus Pro 3

[MrMojoR]

Describe the bug I'm running from ARMv7 docker, my docker-compose looks like this:

version: "2"
services:
  neolink:
    image: quantumentangledandy/neolink
    container_name: neolink
    volumes:
      - /storage/neolink/neolink.toml:/etc/neolink.toml
    network_mode: host
    restart: unless-stopped

my neolink.toml looks like this:

bind = "0.0.0.0"

[[cameras]]
name = "kapu"
username = "admin"
password = "***"
address = "192.168.0.233"
uid = "****"
stream = "mainStream"

My docker log looks like this:

After I try to open the stream in VLC I receive this error in the log, in homeassistant when I try to add it as a generic camera, it connects, but no picture is displayed, what am I doing wrong?

Expected behavior The rtsp stream should be displayed in VLC.

Can't really tell from your log what might be up. You could try some things like setting buffer_size = 0, or using one of the older tags.

I'm working on a major rewrite of the code atm which will rewrite how buffers are pushed onto the app src so maybe it will help but the rewrite is still about a week away from completion.

[MrMojoR]

Ok, thanks for you hard work, I'm looking forward to it. Will try these suggestions.

[QuantumEntangledAndy]

If you could set the variable GST_DEBUG to 3 and try again it could provide more information. The log suggests that the gstreamer thread is failing so passing that variable might help. (This debug log can get huge though)

[MrMojoR]

It was working for a bit with buffer_size=0, but I have enabled cameras.pause feature, and there are new errors in the debug log:

[QuantumEntangledAndy]

I need more of the log, failed to preroll pipeline means that something went wrong LONG before this point. While the pipeline was being prepared

[MrMojoR]

Here is the full log, when starting then trying to connect with VLC:

Hmm different error now. Not what I was expecting from the log either. It seems the video is working fine but then gstreamer throws an error. Perhaps the audio is not decoding right. Could you put this environmental variable RUST_LOG to "debug". That should then print what format was detected. You may also want to try disabling audio in the official client to see if that makes a difference.

[MrMojoR]

Thanks, it is working now in HomeAssistant, unfortunately it was draining the battery, so I have tried the MQTT integration, which also works great, but still drains the battery. Also with neolink and using the default reolink app, motion is never detected, and no clips are recorded, no notifications are sent. I think it is because the app thinks that we currently watching the stream when using neolink. I won't be using this for now, but I really like the concept, thanks for your efforts!

[QuantumEntangledAndy]

Yes battery is an issue. There's a couple of plans to address this such as disconnecting when no clients attached and watching push notifications to detect motion to reconnect too.

[QuantumEntangledAndy]

Seems your original issue was addressed so I will close this one
