Has anyone figured out yet how to RTSP stream channel 0 "multi stream"?

Channel-0 displays can display all 16-channels simultaneously in a single stream on a single channel and this results in smooth playback and low bandwidth. I have confirmed on SmartPSS that this functionality DOES work when I select "Zero Channel Preview" -> "Split 16" -> "1-16". Then magically, I can see all my 16 cameras on what Dahua calls "Multiplay Stream" @ 1080P. Cars driving by are all smooth like butter.

The problem is... I cannot for the life figure out how to stream this across RTSP. I've tried every single combination like the following. YES RTSP works for me for a single channel. But I cannot access channel zero.

rtsp:/192.168.x.x:554/cam/realmonitor?channel=0&subtype=0
rtsp:/192.168.x.x:554/cam/realmonitor?channel=0&subtype=1
rtsp:/192.168.x.x:554/cam/realmonitor?channel=0&subtype=0&mode=split16
rtsp:/192.168.x.x:554/cam/realmonitor?channel=0&subtype=1&mode=split16
rtsp:/192.168.x.x:554/cam/realmonitor?channel=0&subtype=0&mode=split16&group0
rtsp:/192.168.x.x:554/cam/realmonitor?channel=0&subtype=1&mode=split16&group0

You mean something like that: Dahua NVR2108-I RTSP multi stream in Home Assistant with a low(er) resolution?

As far as I know you must use max. Channel + 1
My NVR2108-I has 8 Channel and so i must/can use Channel 9.
Code:
rtsp:/User:Password@IP:554/cam/realmonitor?channel=9&subtype=0
With you 16 Channel NVR try Channel 17.
Code:
rtsp:/User:Password@IP:554/cam/realmonitor?channel=17&subtype=0

Oh **** it worked. I have a 32 channel so I did channel=33&subtype=0.

HAH! Thanks!

It is works correctly on my NVR2108-I but not on DHI-NVR1108HS-S3/H
As far as I was able to confirm this by testing a total of 7 different video recorders.
Any recorders starting with "1" don't seem to support multi-stream.
NVR starting from 2104 and up support this by specifying max channel + 1 as Jim_OS has pointed out.
On XVR's you can use this by simply specifying channel=0

On some (because I can't check all) this is not the channel 0 style but is streaming the local HDMI output over RTSP.
So you get whatever is on that GUI currently. Select which cameras, layout, do a tour, alarm activation etc.
And if you use the CGI you can control what is being output on the screen remotely.
