Substream not working on Argus Pro

[Morphy99]

Describe the bug Substream doesn't appear to be working. I've tried enabling debug logging by opening a sh terminal in portainer with "set RUST_LOG=debug" but the only logs I get are:

To Reproduce Trying to playback url rtsp://un:pw@ip:8554/camera/substream results in "Failed to connect with rtsp://un:pw@ip:8554/camera/substream" error in VLC

Expected behavior Stream to play in VLC

Versions NVR software: Neolink software: 0.4.0 Reolink camera model and firmware: Argus Pro

Could you set GST_DEBUG=3 and post those logs while when you try to connect from vlc. Also I believe that case important so please try subStream instead of substream

I noticed this after starting the container:

It seems your setting usernames and passwords to connect to the rtsp stream. Perhaps you should debug without because from your logs it seems that your not supplying the correct passwords in the url.

Also your log still says media '/front/substream' rather than media '/front/subStream'. This could just be the way gst debug prints but please ensure you show the logs when it is in the subSteam case. Also what happens when you do just /front

[Morphy99]

Sorry for the delay, life getting in the way again! Had another play this morning and it seems the substream isn't working when I define in a user in neolink.toml. The same credentials and player works fine for the normal stream (/front). When I remove the credentials from the config I can connect OK with substream.

[QuantumEntangledAndy]

Intersting. Well please provide the debug log with the environment variable I mentioned before. It should tell us what is not authenticating

[Morphy99]

That is the debug log with GST_DEBUG=3 here

[QuantumEntangledAndy]

Are those the whole logs? I was expecting more such that revealed the login/auth stages of the client etc.

[Morphy99]

FFS my bad. It does work with the subStream url. I'm not sure why, but my VLC changes the url to /front/substream despite me entering the correct one :angry: I've tested it with frigate which is what I'm using the stream with and it's working OK with the correct URL and authentication.
