Dahua IPC-T5442TM-AS-3.6mm Green Screens, other makes work fine........

[pm1961]

Hi,

I have Frigate working as a Docker in Unraid.

I have a working Home Assistant VM through Unraid with the Frigate Proxy addon.

Frigate works fine with two other brands of cameras, however my Dahua refuses to do anything else but "green screen". It has previously worked, but I don't know at what point it broke.

I have the simple config below, with no extra hardware arguments.
The rtsp line works fine with VLC and also within HA using the Custom WebRTC Camera card.

The camera also works fine within a web browser.

Also below are the log lines.

I'm frustrated, so any pointers gratefully received thanks.

Something doesn't seem right with the config you're providing. the logs complain of rtsp://admin:xxxxxxx@10.10.40.60:554/cam/realmonitor?channel=1&subtype=2 which is different than the snippet you provided

Hi, ah, I thought that was because I had a substream entry as well? I didn't include it because I didn't believe it was part of the problem... but here is the entry for that camera............ Thanks for looking.

So the camera is complaining that it can't find that, are you sure that specific camera supports 3 different streams (and are they enabled?)

What happens if you set subtype=1 instead?

[pm1961]

Yes definitely supports 3 streams...... but you've hit the nail on the head....... At some point the substream got "unticked" in the camera settings. My thought that one stream wouldn't affect the other is obviously flawed!

Every day's a school day! I'll take the Numpty of the Day Award.....

Thanks for taking an interest.
