HTTP feed from a substream - 5231R

[dastrix]

hi guys

im trying to put web cam feeds into openhab, by using the URL encoded with the username/password.

I cant seem to work out how to get the live video feed. The only thing that works in the snapshot (http://admin:password@192.168.0.245/cgi-bin/snapshot.cgi

can anyone assist? RTSP isnt an option

thank you!

You should be able to set a substream to mjpeg and use that. All of the other options use RTSP.

You could also transcode/restream the feed via HLS or WebRTC. A number of software VMS have this functionality or it can be done with things like ffmpeg.

Yeah transcoding is something I want to totally avoid. Ill see if I can find the substream mjpeg options

It's basically just

/cgi-bin/mjpg/video.cgi?channel=1&subtype=2

you have to set up substream 2 first.

The other thing that could trip you up is digest authentication, but there's a setting on the camera you can use to turn that off if you need to.

OK, that appears to work! nice, thanks mate

Hi there, well you were right. Digest auth is tripping us up. Which is the setting to change as I only see under SECURITY an option for RTSP? I set it to BASIC and I can see in TCP dump its still using Digest

I think you're right, that setting may only effect the rtsp stream.

Simplest option is probably to figure out a way to get digest auth to work in open hab or whatever you're using.

Not that easy. Working with a freelancer who has tested a python wrapper thats worked - we will test it tomorrow on the cameras and see. I just dnt see why Dahua cant give people the OPTION

Any chance of sharing that Python wrapper?
